Wildlife management in Europe outside the Soviet Union. - NINA Utredning 018: 1-47. Myrberget, S. 1990. Viltstell i Europa utenom Sovjet-Unionen. -NINA Utredning 018: 1-47. A review is given on principles and practices used in wildlife management in Europe outside the Soviet Union. Emphasis is placed on game species, but some conservation measures for threatened mammals and birds are also described. Management practices vary from country to country. The most productive game harvesting systems are found in areas where landowners control hunting rights, or where the harvest is strictly controlled by official authorities or hunting organizations. In some other countries where hunting rights are free, many game populations appear to be over-exploited, and general opposition to hunting is increasing. There are about 8 million hunters in the area described, i.e. 1.6 hunter per km2 land area. En oversikt er gitt over prinsipper og praksis brukt i viltstellet i Europa, Sovjet-unionen unntatt. Vekten er lagt på jaktbare arter, men også noen vernetiltak for truede arter er beskrevet. Metodene benyttet i viltstellet varierer fra land til land. De mest produktive jaktbare bestander har man i land hvor grunneierne eier jaktretten eller hvor myndigheter eller jegerorganisasjoner strengt regulerer jaktuttaket. I en del andre land hvor jaktretten er fri, er åpenbart mange viltbestander overbeskattet, og motstanden mot jakt er økende. Det er ca. 8 millioner jegere i området, dvs. 1,6 jeger pr. km2 landområde. Key words: Game management hunting.

In keepingwith my promiseto do so,the manuscriptwas deliveredto the editorsin 1988. However, it soon became obviousthat there would be considerabledifficulty in obtaining reportsfor all continents. In the autumn of 1989, the book programwas dissolved. This report is a slightlyrevisedversionof the chapter intended for the book. Most changeshave been editorial,or are related to adjustmentsin the emphasison different management schemes.Recentinformationand referencesare added. Some Fennoscandianmanagement practicesare describedin greater detail. However, the report largely follows the plan and styleof the originalmanuscript. Many personsand organizationshavefulfilled my requestfor information.In particularI would liketo thank E. Ueckermann (FRG) and J. Kovacs(Hungary).

Emphasisis placed on management principles. Some management practices are also described in detail, in particular those undertaken by centralor localauthoritiesand by hunting organizations.The reportdoes not providemanyguidelineson how privateindividualsmay aid wildlife. The original proposalfor this report excludedthe European part of the SovietUnion (USSR).lt does not includeany information on wildlife in Cyprus,the Azoresor Madeira. Areas situated outside the Palearctic(e.g. Greenland) are also ex, cluded, as are small republicslike Monaco and San Marino. No informationwas availablefrom Albania. The northern limit of Europeis 800 N at Svalbard(Norway). EuropeincludesIceland in the northwest, and the southern border is formed by the Mediterranean and the islandsof Malta and Crete (approximately350 N). The total land area, exclusiveof the USSR,comprises4900 km2, and the population isabout 500 million. The naturalhabitats,culturesand historyof Europeare asvaried as the multitude of economic and political systems. Therefore, practicesand principlesof wildlife management alsodifferfrom countryto country. The informationgiven is not equallycomprehensiveand detailedfor all partsof Europe.This is mainlydue to restrictions in the author'spersonalknowledge,which is more adequate for Nordic countries.Much of the literaturestudiedwas written in Englishand German. Hence, Mediterraneanareasare lesswell coveredthan other partsof Europe. 1.1 Wildlife versus game This report mainly considersspeciesrecognized as "game", i.e. speciesof birds and mammals which are hunted. The definitionalsoincludesall specieswhich were formerly hunted or which may be hunted in the nearfuture. In this report the term "hunting"is not restrictedto the Britishinterpretation"huntingwith hounds".It includesall forms of harvestingwild mammalsand birds,suchas shootingand trapping, consistentwith the definition given in the lrish WildlifeAct of 1976. The term alsocompriseshunting methods like falconry and the use of bow and arrow, which are only permitted in a few countries (e.g. Turkey and Denmark). • The definitionof "game"does not take into considerationthe purpokeof the harvest,which may be exploitationas meat, skinsor trophies.Much hunting is done for the sakeof sport. Some speciesare controlled for various reasons.In some countries,the pkking of eggs of certain speciesis regulated by game acts,e.g. in Norway and on the Faroes.Commercial sealingand whaling are not included in the categorygame hunting. Specieswhich are hunted vary from country to country and with the passageof time. As an example, the stoat (Mustela erminea) and the squirrel (Sciurus vulgaris) were important sourcesof fur in Fennoscandiauntil World War II, but are seldom exploited today. Eider ducks (Somateria mollissima) have been protected in Norway for more than 100 years, while they constituteone of the most important game speciesin Denmark. Most raptorsand owls are protectedin the majority of Europeancountries today, although they were once heavilypersecuted. Many countries have compiled lists of "game" and "nongame" species.Within the latter category a group of "pesi" speciesmay be defined. Definitionsand their usagevaryfrom countryto country.An example regardingbirdsis the Game Act in Great Britain,which stipulatesa closedseasonfor Galliformesbirds.The Wildlifeand CountrysideAct 1981 included hunting regulatiorisfor some "sporting and quasi-sporting birds"(see RSPB1989). The last act also listed a number of "pest"specieswhich may be caught or killed by authorized persons. In certaincountries,laws regulatinghunting alsogovern the protectionof non-hunted species.Such is the case in Norway, where nearly all mammals, all birds, amphibiansand reptilesare referredto in the WildlifeAct. Seals,which are regarded as game in most other Europeancountries,are not coveredby the WildlifeAct in Norway (but sealsare regarded asgame on Svalbard). This report does not exclusivelytreat problemsdirectly related to game and pest species.Protectionmeasurespertaining to other birds and mammals and their habitatsare alsodiscussed,in Whichcaseemphasisis placedon faunal conservation. For practicalreasons,the contentsof the report are confined to wild living birds and mammals with the exceptionof microtine rodents,bats, insectivoresand whales.The definition of "wildlife"isthus much more restrictedthan the Britishconcept, which includesall fauna and flora. © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 1.2 What is wildlife ment? manage- game foods, and helping vulnerable populations and species. Many hunters seem to believe that these are the most important measures of wildlife management, but often they are mainly of local significance. I adhere to the definition given by Giles (1978, p. 4): "Wildlife management is the science and art of making decisions and taking actions to manipulate the structure, dynamics and relations of populations, habitats and people, to achieve specific human objectives by means of the wildlife resource". In most countries the major goal of wildlife management is to protect the naturally occurring abundance and genetic variation of wildlife species. The European Council Convention on the Conservation of European Wildlife and Natural Habitats, which was signed at Berne in 1979, resolved that populations should be maintained at a level corresponding to ecological, scientific and cultural requirements, while taking into account economic and recreational requirements and the demands of sub-species, varieties, or other forms which are regionally endangered. This is now the basic goal for wildlife management in western Europe. In principal, the same applies to all of Europe. The most important elements of wildlife management are manipulation of wildlife populations and their environment. Wildlife management should serve definite purposes, but should not be restricted to increasing hunting yields. As an example, let us examine the objectives of hunting and hence of game management described by the German Hunting Association (DJV 1987, translated from German): Hunting is applied conservation, when used as a means of safeguarding the survival of a diverse animal and plant life. Hunting should exploit several game species, while endeavoring to maintain the total indigenous fauna, and at the same time ensure the balance between game populations and their native habitat. Threatened species should be protected, and opportunities should be provided for the re-establishment of species which have been eradicated. The destruction of habitat exploited by free ranging populations of game species should be prevented. Exploitation, including taking care of meat, skins and trophies, is a fundamental aspect of game management. However, hunting which is indifferent to the future of a population, or which entails cruel or inhumane methods is not game management. Major issues include planning exploitation strategies and endorsement of laws and provisions pertaining to hunting, and anti-poaching measures. Wildlife management also involves conservation and improvement of wildlife habitats. However, human interference or alteration of habitat may benefit one species, while having negative consequences for another. The habitats of threatened species are of particular importance, Habitat management is today the most important aspect of wildlife management. A third theme of wildlife management concerns solving or diminishing problems caused by certain wildlife species, such as damage to forests, livestock and fisheries, and diseases common to game and livestock or human beings. The fourth major theme of wildlife management involves practical measures for assisting specific wildlife populations, e.g. re-stocking, feeding, carnivore control, production of 7 ninautredning018 2 Historical perspective The history of hunting and wildlife management in Europe spansover 5 different Eras,but the timing variessomewhat within the continent: a) prehistoricEra, b) the Eraof Classic Civilizationfrom 1000 B.C. to 500 A.D. followed by great social disturbance,c) the Eraof aristocratichunting rights and exploitationof game stocksfrom 800 AD. to 1850, d) the Era of conservationawarenessand predator control until 1950, and e) the Eraof modern game managementand natureconservation.During period (e), managementmeasureshave increasinglybeen basedon resultsfrom wildliferesearch. Only the first three Eras(a-c) are treated in this chapter. The divisionof Erasdoesnot relateequallywell to allcountries. 2.1 Prehistory Neanderthalman livedin Europeduring the lastice age, and was replacedby modern man in the great interglacialperiod about 35,000 yearsago. Both of thesetypesof human were hunters and gatherers (Cornwall 1968). They hunted large mammals, and the fauna existing at that time (the upper Pleistocene,100,000 - 10,000 B.C.) was very different from today's(Kurten1968, Kowalski1986). - Among the large prey specieswhich are now extinct were the woolly mammoth (Mammuthus primigenious), the woolly rhinocerus (Coelodonta antiquitatis), the giant deer (Megaloceros giganteus), the auroch (Bos primigenius), the steppewisent (Bison priscus) and the cavebear (Ursus spelaeus). Other specieslike the cave hyena (Crocuta crocuta spelaea), the cavelion (Felis leo spelaea), the saigaantilope (Saiga tartarica) and the caballine horse (Equus przewalskii) have disappeared from Europe, but still exist in other areas, partly as other sub-species. Total or partial extinction during the upper Pleistoceneprimarilyaffectedlargerherbivores,and the carnivoresand scavengerswhich exploited them. These extinctionscan hardly be explained by climatic variation alone. Extinctionstook place parallelwith the expansionof prehistorichuman populationsand their advancementas big game hunters.Therefore one cannot eliminate the possibilitythat hunting may have contributed to the exterminationof some large mammalsduring the Pleistocene(Martin 1971). The substantialclimatic changeswhich took place throughout the Pleistocene,affected vegetation and fauna. During colderperiods,arcticanimalslikereindeer(Rangifer tarandus) and muskoxen(Ovibos moschatus) were evenfound in southern Europe.In certain time periodsand in some areas,hunt- ers specializedon particularprey specieslike the cave bear, the woolly mammoth, primitive horses and wild reindeer (Berger& Grönberg1931, Lindner1937, Spiess1979). Examinationof late stone age settlement sites from after 10,000 B.C. indicatesthat other prey speciesbecame more important, includingsomewhich are significantgame species today (Howell 1972, Clutton-Brock1981). Among thesewere the red deer (Cervus elaphus), wild boar (Sus scrofa), and the roe deer (Capreolus capreolus), while small game like hares (Lepus spp.) were probably lessexploited. Fur bearinggame was alsovital. Birdswere exploited to the extent permitted by available hunting techniques, and then particularlyin coastalareas(e.g. Scheel1947). There is no informationon whether any kind of game management, was practiced in prehistoric times. As previously mentioned,somegame specieswere probablyexterminated. However,the abundanceof carvingsand paintingsmade by stone age man in cavesand on rocks,indicatestheir magical function related to fertility and hunting luck (e.g. Lindner 1937). About 5,000 B.C., animal husbandryand agriculturebecame the main way of livingin large partsof Europe(Clutton-Brock 1981). The consequences were enormousfor wildlife habitat. Hunting and trappingcontinuedto be majoroccupations. 2.2 Historical times up to 1850 The golden age of Greek and Roman civilization.Throughout the first millenium B.C. until around 500 A.D., Greek and Rornanculture influenced most of Europe.This culture was influenced by Egyptian, Babylonian,Assyrian, Phoenecianand Jewish/Christiancivilization.Severalof these cultureshad developedsophisticatedformsof game management (Chalmers1936, Alison1978). Hunting•was regarded as sport among the aristocratsof Greece, although this was ndt always highly approved. In 600 B.C., Solon prohibited Atheniansfrom hunting, in the belief that hunting led to neglect of other cultural activities (Leopold 1933). He also introduced a bounty system for killedwolves(Canis lupus) (Johnsen1947). The first book about hunting was written under the title Cynegeticus by Xenophonwho livedfrom 440-354 B.C.(seeDakyns1897). The book discusseddifferenttypesof huntingon popular game speciessuch as deer, wild boar and hares. Hunting was regardedas a meansof encouragingthe physical developmentof young men and improving their morals. Hareswere often setfree after being caught, asa token offering to the goddessof the hunt. © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 Around 100 A.D., the area controlled by the Roman Empire was bounded on the north by the Donau and Rhine rivers and the narroweststretchof Scotland.The Romansimproved traditional hunting technology including weapons like the spear, the arrow, the use of traps, nets and lime sticks.Falconry was introduced into Europe in the 4th century A.D. (Tillisch1949, Lindner1973). At the time of Christ there was an abundanceof game like the wolf, deer, wisent (Bison bonansus), auroch and moose (Alces alces). Julius Cæsar (100-44 B.C.) related that the abundance of game in Germany made hunting restrictions superfluous(Whisker1981). With the exceptionof agriculturalland, hunting was usually open for all free men, but was largelycontrolled by families and village societies(Lindner 1940). Hunters were given rightsof ownershipwhen prey animalswere localizedsuchas through tracking.Thiswas alsothe casein the Nordic countries where lawswritten down in the 11-13th centuriesconfirmed individualrightsto particularhunting terrain, bearsin hibernationand the nestsof birdsof prey (Østlie S.a.). These laws alsocontained rulesfor dividing up the yield. In some parts of Sweden and in Iceland, hunting rights belonged to the landowner(Lindner1940). The first real hunting lawswere introduced by the Romans. No one owned live game, the principleof res nullius, but a landowner could prohibit hunting on his own land. Ownership rights to game first applied after the game was killed, and this alsoappliedto illegallyhunted game (Lindner1937). A commoner could hunt smallgame, but rightsto deer, wolf and brown bear (Ursus arctos) hunting were reservedfor the aristocracy,who alsohad exclusivepriviledgesto keepcertain breeds of hunting dogs (Whisker 1981). Laws prohibiting hunting on cultivated land were enforced and game parks were established. Beforethe fall of the western RomanEmpire(476 A.D.), and during the followIng two centuries,considerableunrest resulted in large migrations of Germanic and Slavic tribes. Therefore, hunting regulationspreviouslybound by custom no longer applied. In addition, soldiersoften relied upon game for food. In many placeswildlife populationsrapidly declined. There is no evidenceof activewildlife managementin Greek/ Romanculture. Huntingwas not alwaysan honourablesport, as evidenced by the thousandsof animals killed in bloody theatrical performancesin arenas (Auguet 1972). Most of these animalswere imported from other parts of the world, but some Europeanspecieswere alsoused. In many partsof Europe,ruthlesshunting and trapping by the Romansresulted in the decline of severalwildlife populations.Neither did Christianethicsintroduce any moral obligationsfor protecting wildlife populations(Whisker1981). Hunting priviledges of the aristocracy.-After the fall of the Roman Empire, a gradually increasingportion of hunting rights was taken over by the aristocracy(Leopold 1933, Whisker1981). The establishmentof royal"forests"in Germany from 648 A.D. was important for the development of hunting rights within the rest of Europe.These forestswere formerlycommon land where the rightsto hunt somespecies likedeer or wild boarwere reservedfor the king and hismen. A king could hand over hisrightsto the aristocracy,a cloister, or a free city, which in turn might transfersome of them to the common people (Lindner 1940). After the development of feudalism,which enjoyedits peakon the continent around 1000 A.D., most land and hunting rightswere controlledby the king and his feudal chieftans.To the presentday, most Europeanhunting ritualsand termsare of Frenchorigin from medievaltimes(Phodpus1978). Some animalsescapedfrom captivity. New specieswere introduced to Europein this manner, while other speciesextended the rangeof their distribution.The pheasant(Phasianus colchicus) is one example. Mythology states that the pheasantwas introduced into Greece from Kolchisnear the BlackSea by Jasonthe Argonaut around 1300 B.C. (Hill & Robertson 1988). The Romans later introduced them to France and Germany. The fallow deer (Cervus dama) was brought from AsiaMinor and kept in game farms.They were brought to France and Germany around 400 A.D. (SOU 1983). Rabbits(Oryctolagus cuniculus) only occurred in the wild in Spain, Portugaland the south of France2,300 years ago, but they were spread to most of the Mediterranean countries by the Romans and Phoenecians(Clutton-Brock 1981). Doves (Columba livia) establishedsemi-feralpopulations (Lever 1987). The doormouse (Glis glis) was considered a delicacy by the Rornans,and was in recent times in Englandafter escapingfrom captivitytreated as a pest(Lever 1985). Anglo-saxonsin Great Britain,originallyadheredto unwritten germanic laws.The oldestgeneralgame law was introduced by the Danishking Knut in 1016. The law establishedthat no one owned wild animals,but that the king had some'hunting priviledges. Feudalismwas establishedin England by William the Conqueror (1066-1087), who also introduced a systemof royal "forests".Rightsto private "chase"were alsomaintained. Illegal huntingwas punishableby death or mutilation. Germanic tribes.- Hunting and trapping were vital to the survivalof Germanictribesliving north of the RomanEmpire. 9 ninautredning018 The first Englishlaw pertainingto the forestand wild animals was introducedby Henry Il in 1184. This and later lawsstated that all hunting of the most important wildlife species was a priviledge reservedfor aristocracyand the church. Fencingof game forests was permitted, and management within such parksincluded many types of measures(Gilbert 1979). By the end of the 11th century there were 31 red and fallow deer parksand more than 70 hayes,i.e. lessformal enclosuresfor deer (Vandervell & Coles 1980). These lawsresultedin an extreme stateof bureaucracyand the appointment of knightsfor the purposeof protectingthe hunting rightsof the king. the people.Thiswas the caseboth in Franceand in countries occupiedby Frencharmies(e.g. Bubenik1989). Hunting seasons.-Accordingto the first Englishbook about huntingwritten by EdwardII Duke of Yorkin 1406-1413 (see Baillie-Grohman& Baillie-Grohman1907), traditional limitationson hunting methodsand hunting seasonswere already enforced at that time. Good sportsmanshipprohibited the shootingof pregnant animals,or femaleswith smallyoung. Seasonalchangesin the conditionof furs and peltswere also taken into consideration.Customsconcerningthe protection of animalsduringthe breedingseasoncan be tracedto much older traditions,asdescribedin the Fifth Bookof Moses22:67 (seeGilbert& Dodds1987). After 1200, violation of hunting laws was not as seriously punishedin England as previously.The bureaucraticsystem was graduallydissolvedby corruptionand as a consequence of the BlackDeath of 1348/49. By around 1600, mostof the royalforestshad been turned over to privatelandownerswho were also given the right to control trespassingand hence hunting on their property. In 1578-80 more than 700 deer parkswere registered(Vandervell& Coles1980). Regulationsfor the protection of individual wildlife species were firstlegallyenforcedin Englandin 1536 (Whisker1981). However, the moosewas seasonallyprotected in Swedenas early as 1351 (SOU 1983). Much older Swedishlandscape laws enforced seasonalprotection of the squirrel (Lindner 1940). In Germany local restrictionsin hunting seasonsof brown bears and wild boars were enforced already in 890 (Lindner1940). Hunting priviledgesoffered hunting as a means of physical trainingand enjoymentfor the nobility.Noblemencompeted not only for quantitiesof game, but alsofor the qualityof trophies,particularlyred deer antlers.The weight and number of pointsof the antlerswere carefullyrecorded,and the best were mounted (e.g. Bubenik1989). Active wildlife management.- Organized management designedto increasegame populationswas first initiated in Europe after 1500. Most of the methods used were Indirect", i.e. they were aimed at preventing habitat encroachment such as burningcovervegetation, or disturbanceduring the breedingseason(Leopold1933). Establishmentof regal and aristocratichunting priviledgesoccurredsomewhatlater in the Nordiccountriesthan in Central Europe.Hunting big game becamethe exclusiveright of the Swedisharistocracyin 1351 (SOU 1983). Swedishfarmers were completely deprived of shooting rights in 1647, and alsoof all trapping apart from carnivoresin 1664. The hunting rights of Swedish landownerswere renewed in 1789 (Nordell & Weinberg 1983). By deliberateintroductionsor escapesfrom captivity, many game speciesexpandedtheir distributionin Europealso before that time (see above). It islikely that vikings brought grey partridges(Perdix perdix) to Öland and Gotland in Sweden already around 500 A.D. (J. Dahlgren in Andersson 1988). In Denmarkthe king and noblemenexdusivelyheld hunting rightsin 1537, and a death penaltywas imposedfor extensivepoaching(Hansen 1928). In 1781, the Danishlandowners got back most of their hunting rights. Hunting rights in Finland, Norway, and Switzerlandcontinued mainly to be held by farmersand other landowners,with the exceptionof the Swedish/Finnish AalandIslands(Salo1976). Pheasants,were kept in Great Britain in the 11th century (Vandervell& Coles1980), and were introducedinto Ireland around 1500 (Lever1987). Rabbitsgraduallyspreadto most of Europeafter escapingfrom captivity(Clutton-Brock1981). Reddeer and roe deer were introducedto the Aalandislands around 1500 (Salo1976). Mallards(Anas platyrhynchos) were bred and releasedin Englandfrom at least 1651 (Leopold 1933). The 16th and 17th centurieshave been calledthe golden era of hunting(Bubenik1976). Farmersand cloisterswere forced to assistthe aristocracyduring the hunt, which was often conducted regardlessof ripening crops. The situation was particularlyabusedin Franceand Germany,where aristocratic priviledgeswere first revoked after the revolutionsin 1789 and 1848. After the French Revolution,Codex Napoleon replaced Rornan law and proclaimedthat game belonged to The popularityof game introductionsand stockingincreased after 1700. Pheasantswere imported to Swedenin the beginning of the 1700's, and the wild boar was re-introducedto Öland in Swedenin 1731 (Berger& Gröndahl1931). The capercaillie(Tetrao urogallus) was re-introducedto Scotlandin the 1800's, and stockingsof pheasant and grey partridge took placein severalcountries(Lever1987). Brownhares(Le10 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 pus capensis) were introducedinto Irelandin the 1800's (Lev- which became extinct in 1844 on Iceland(Greenway1967). Royalhuntson swans(Cygnus spp.) during the moultingperiod (Weismann1931) led to populationdeclines.The beaver (Castor fiber) was exterminated on the BritishIslesaround 1200, and in most of the remainderof Europein the period 1500-1800. er 1985). Around the sametime, active habitat management measures alsobecamemore common. Forinstant,partridgeswere wintered in indoor pens in Sweden in 1760. Salt lickswere set out and cabbagewas plantedasextra fodder for game populationsin Swedenat the sametime (SOU 1983). In spite of their deficiencies,hunting laws introduced after 1000 A.D. did protect many wildlife populations,by limiting the number of personsallowed to hunt. When these restrictions were removed, many game populationswere quickly overexploited.AlreadytWo yearsafter the revolutionof 1848 in Germany,regulationsconcerningminimum sizeof hunting areaswere introduced to reduce hunting pressure(Ueckermann 1984). Combating predatory animals.- Much hunting was done to combat predatoryanimalsresponsiblefor injuring and killing domesticlivestockor preferredgame species.The wolf was a major target for such measures.The last wolf was killed in Englandin the 1500's, in Irelandin the 1600's, in Scotlandin the 1700's (Bibikov 1988), and in Denmark in 1813 (Weismann 1931). From about 1350, all of the inhabitantsof Sweden were obliged to contribute to the extermination of predators,and after 1442 all Swedishfarmerswere required by law to maintainspecialwolf nets(SOU 1983). Some changesin human use of landscapeswere favourable to manywildlifespecies,su,chas reforestationof earlierarable or barren land (e.g. Ueckermann1984). Of particularimportance were plantings and other measuresto increasethe amount of hedgerowson agriculturalland in the 18th and 19th century (e.g. Nielsen et al. 1967, O'Connor & Shrubb 1986, Moore 1987). A systemof bountieswas already introduced in Englandin the 1500's. A wolf bounty was establishedin Swedenin 1647 (Johnsen1947). Otters (Lutra lutra) were controlledbecause of their supposeddamage to fisheries(see Baillie-Grohman Baillie-Grohman1907). A bounty systemdesigned to control birdsof prey and owls was introducedin Swedenin 1741 to increasesmall game populations(SOU 1983). Bounty systems covering a varying number of specieswere in use in many countriesaround 1800. 2.3 Synthesis Many of the game managementstrategiesusedin Europetoday were developed in the 1800s, although many practical measureswere introducedeven earlier. The effects of hunting on wildlife populations.- The effect of hunting on wildlife populationsdepended somewhat on the effectivenessof the methods employed. Trapping methods in general usewere continuallyimproving (Frank 1984). The crossbowwas alreadycommon by 1100. Hunting guns became available around 1500. By the beginning of the 1500's, the shotgun had also been developed (e.g. Brander 1971). The practiceof usingpointingdogs was steadilymore popular during the 1600's. However, truly effectivehunting weaponswere not invented beforethe beginningof the 19th century(e.g. Hansen1928, Danneviget al. 1983). Leopold(1933) describedthe order of succession of different game management measuresas follows: 1) restrictionof hunting, 2) control of predators,3) establishmentof game parks, 4) introductionsof game, and 5) improvement of wildlife habitat. However,the order of successionof points1 and 2, measureswhich both started in pre-historictimes, is largely built on the fact that hunting predated animal husbandry. The goals of game management had until 1850 changed from a meansof safeguardingaristocraticpriviledges,to protection and improvement of wildlife populations.Although publicationsconcerning animal rights date back to 1723 (Whisker1981), these attitudeswere not reflectedin historical game management. In associationwith the developmentof more effectiveweapons in the 1600's, and the more widespread use of guns, many wildlife populations in England, Central Europe and Spainwere overexploited(Whisker1981). The qualityof deer trophiesdeclined(Bubenik1989). Populationsof otter were alreadyheavilyreduced in Sweden in the 1500's. The wild boar becameextinct in Englandin the 1500's, likewisethe capercailliein Great Britainaround 1790 (Lever 1987). The last living auroch died in Poland in 1627 (Szafer1968). The only smallgame speciesto be completely eradicated by hunting was the great auk (Alca impennis), 11 nina utredning 018 3 Authority wildlife to manage Germany (GDR) these territories may range in size from 1,000 to 4,000 hectares. Hunting terrain in western Europeis largelyprivatelyowned, but many areasare common property or belong to the government (e.g. seeFACE1986). Hunting rightsusuallybelong to the landowner,who makesuseof them personallyor leasesthem to individualhuntersor hunting associations. Official authoritiesmay, however,in some countries(e.g. in Norway) demand that the landownersellgame licensesto the public, or that propertiesarejoined into common wildlife areasin order to meet the minimum area requirementsfor hunting big game. Wildlife management is generally carried out by official authorities, landowners, personswith legal hunting rights at their disposal,or even by anyone, e.g. in their gardens.To educate management personellat different levelsand hunters, a varying number of educational programs have been started at universitiesor lower grade schools,or are organizedby differentassociations. In this reviewwe concentrateon game management.If other aspectsof wildlife management are taken into consideration, many other authorities,associationsand privatepersonsdo a formidablejob. Hunting isopen to all of the citizensof Portugal,Italy, Greece and Turkey, in all areas except national parks and reserves and some agriculturalland, but regionalauthoritiesmay prohibit hunting in someareas.In some cantonsin Switzerland, all citizens may exercisethe right to hunt within canton boundariesaccordingto a "patent"system(DJV1987). 3.1 Official authorities Game management was traditionally administered by the Ministry of Agricultureand Forestry.This is still the case in eastern Europe, and in some western countries including West Germany (GFR), Finland, and Sweden.This is alsothe case in Turkey (Anonymus 1986b). Today, game management is the responsibilityof the Ministryof the Environment in some countrieslike UK, France, Luxembourgh,Denmark and Norway. Tasksrelatedto game managementare carried out in Iceland by the Department of Education.In Ireland wildlife problemsare since 1987 handled by the Dep. of Finance,Officeof PublicWorks(WildlifeService1989). In many countriesproperty must be of an establishedsizeif the landowner wishesto exercisehunting rights. In some provincesof France,the municipal government administers hunting rightson all propertiessmallerthan 25 hectares.In other parts of France, hunting rights on propertiesof less than 20, 40, 60, 80 hectaresrespectivelyare administeredby a municipal hunting association(Premier Ministre 1966). Hunting territorysizeis alsoregulated by the governmentin West Germany and other western countrieswhere the "revier"systemis used. State, canton and provincialofficesmay alsomake laws and regulationsconcerning wildlife management. Law enforcement may be delegatedto lower levelsof administration.For example, in accordancewith the Wildlife Act of 1981, most legal decisionsconcerning wildlife in Norway are made by the Directoratefor Nature Management. However,many casesare handledat the county level(18) or by municipalgame boards(about 450). 3.2 Hunting At the open sea,and alsoon the shorelinein many countries, hunting is in generalopen for everyone.Certainspeciesmay be hunted regardlessof hunting rights, as is the casewith large carnivorousmammals in Finland (Anonymus 1989b). SwedishLappsare allowedto hunt on some privateproperty belongingto others(Nordell & Weinberg 1983). Legal provisionsin many countriesdelegate hunting rights and responsibilities to huntersassociations.In suchcasesprincipal decisionsare made through joint cooperationbetween huntersassociations and Central or localauthorities.Thissystem of game management is largelyconfined to easternEurope, but is also partly used in some western countrieslike West Germany.Hunting associationsare alsodelegatedsome authority in Swedenand Finland, but have no officialstatus in Great Britain,Denmarkand Norway. However,someof the operational expenses incurred by hunting associationsin thesecountriesarecoveredwith governmentfunds. rights The hunting priviledgesof the aristocracyhave even been maintaineduntil World War Il in partsof Yugoslaviaformerly belongingto Turkey (Isakovic1970, Adamic 1986a). Today, wildlife resourcesare sharedby the peopleof Yugoslaviaand manged by the government. This is alsothe case in other easternEuropeancountrieseven when wildlife habitat is privately owned. Hunting terrain is divided into territories(reviers)which are managed and usedby hunting clubs(Newman 1970, Briedermann 1981, Krzemien 1987). In East . In many countrieswith private hunting rights, the owner must pay a generalstate hunting fee to be allowed to hunt. 12 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 3.3 The number of hunters In addition he may pay the state for each licenseon felling big game. (See Stensaas(1989) concerningpracticein Norway). Table 1 containsa surveyof the number of huntersin those countriesfor which information is available. Unfortunately data is lackingfor some countries,which in mostcasesprobably have relativelyfew hunters. Hunters and landownerswith hunting rights are most interested in carrying out practicalgame management schemes (e.g. Lindner1985, FACE1986). During a Swedishstudycarried out in 1978/79, 74% of all huntersinterviewed replied that they had participatedin practicalgame managementan averageof 6 daysannually(SOU 1983). More activeSwedish hunters contributed the most time to pursuinggame management. In easternEurope,and those areasof western Europe where the "revier"systemhasbeen introduced,practical wildlife management is obligatory for all personspossessing hunting rights. Accountingfor countriesfor which informationis lacking,the total numberof huntersin Europeoutsideof the USSRis estimated at about 8 million. This figure correspondsto about 1.6 huntersper km2 land area, or about 1.6% of all the inhabitantsof Europe.Huntersare usuallymale; as an example only 3-4% of the huntersin Sweden(SOU 1983) and 2% in Norway arefemale.

Thisfigure is particularlyhigh in Italy with about 5 huntersper km2. Statisticsfor easternturope and Fennoscandiaindicate less than one hunter per km2 area. 3.5 Education in wildlife ment and hunting In German speaking countries, training and education in wildlife management is traditionallyassociatedwith forestry programs (see Ueckermann 1984). For example, in Austria higher educationis providedat the AgriculturalUniversityat Wien, and there are two junior collegeswith training programsfor professionalkeepersor conservationofficers.Hunting organizationsare responsiblefor training and education of professionalhunters. The percentageof huntersin the general populationalsovaries geographically(Table 1). In Nordic countries,this percentageisespeciallyhigh (up to 6% in Finland).Thispercentage is particularlyhigh (17%) on the FinnishAaland Island (Harberg 1988). More than 3% of the populationof Ireland and Greeceare hunters.The percentageof huntersis lowerin eastern Europe, West Germany, the Netherlands and Belgium. 3.4 Hunting manage- In Great Britain, Norway and Sweden, higher education in wildlife managementand wildlife ecologyis alsoprimarilyoffered by agriculturalcolleges.In some countrieslike France and Finland,there are no higher educationprogramsin wildlife management.Wildlifeecologyisoften includedasone aspect of a generaleducationin zoology at universitiesin most Europeancountries. organizations Membership in hunting associationsmay be obligatory or voluntary. There are often severalnational hunting associations in each country. National federationsin countriesbelonging to the EEC(EuropeanEconomicCommunity) are affiliated with FACE(Federationof HuntersAssociations of the EEC). FACEwas establishedin 1978 with headquartersin Brussels, and represents6.5 millionhunters.The International HuntersUnion, CIC (Conceil Internationalde la Chasseet la Conservationde Gibier, InternationalCouncilfor Game and Wildlife Conservation)has influencedthe progressof game managementin Europein severalways. Comprehensivetraining at lower levelsis availablein many countriesincludingGreat Britain,Denmark, Finland,Norway and Sweden. Many young people in Great Britain between 16 and 17 yearsof age, participatein a two year educational programson practicalwildlife management. Personswishing to becomeprofessionalkeepersor huntersusuallytake on apprenticeships. Hunter examinationshave been obligatory in easternEurope for many years. In Poland,all huntersmust first practicein a hunting associationfor one year. If the candidate makes a good impression,he or she is permitted to take a courseand a theoretical examination.All candidatesmust document a working knowledgeof practicalwildlife managementand the useof weapons.After three yearsas an authorized hunter, a new courseis offeredwhich qualifiesthe candidateto shoot male deer. In eastern Europeancountries, hunter authorization is usuallyassociatedwith the right to own a weapon. In western Europe, membership in one or more national hunting associationis voluntary. One exceptkm is Finland, where all hunters belong to a central hunters organization (JägernasCentralorganisation).In a municipalityall inhabitantswho have paid their hunting license,form a game management association(Anonymus 1989b).-No one may belong to more than one association. There are no membershipsfeesand the organizationissubsidizedby funds from the government hunting licensingsystem.The organization is divided into 15 districtsand comprises297 associations. Theoreticaland practicalhunting exarninationshave been introduced in severalwestern Europeancountries. Obligatory examinationswere introduced in Finland in 1964, Denmark in 1969, Francein 1976, the Netherlandsin 1978, Sweden 1982, and Norway in 1987. A type of hunting examination hasexistedin Austriasince1938. Membershipin a hunting associationis obligatoryin eastern Europe,becausehunting associations controland dispenseall hunting rights which are leasedfrom the government. No huntersare allowedto join more than one club, but they may be invited as gueststo the hunting territory of other clubs. Most clubsin EastGermany leasethe rightsto 3 to 5 hunting reviers(Briedermann1981). The content of hunting examinationsvariesfrom country to country (e.g. Helminen 1977, Briedermann 1981, Spitzer 1982, Swartenbroekx1985). Theoreticaland practicalaspects of wildlife management and marksmanshipmay be tested. The only requirementon Icelandisa declarationof satisfactory marksmanshipfrom local policeauthorities.In Swedenthe exam allowsthe purchaseof certaintypesof guns. 14 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 4 Management Somewestern EuropeancountriesincludingGreat Britainand Italy, do not have obligatory hunter examinations.Both of these countrieshave high densitiesof hunters.The Ministry of the EuropeanCouncil (CE 1985a) has ratified a proposal recommendingthe introductionof obligatory hunter examinationsin all member countries. systems Management principlesmay vary from country to country, and with the speciesof animalinvolved(e.g. Dagg S.a.).Variation often dependson the purposeof exploitationor protection, whether the speciesis migratory or stationaryand how hunting rightsare administered. One comprehensivelaw concerninggame managementand hunting is found in most countries.In Great Britainthere are five lawsconcerninghunting (SOU 1983). In the past, hunting laws itemized all wildlife specieswhich were protected, as well as closedor open seasonsfor legal game species.When protectionor hunting seasonof a particularspecieswas not specifiedin regulations,the specieswas regarded as legal game. Today, the opposite practice has graduallybeen introducedin all countries;and all hunting is prohibited unlessspecificallymentioned in hunting regulations. Here "big game" comprisesall large herbivorousmammals. However,thisdefinitionis not alwaysconsistentwith hunters' language.Forexample,in Norway, roe deer are not tradition, ally recognizedas big game, whereasbrown bear are included. Environmentalconservationlaws and regulationscontrolling human use and disturbanceof nature (forestry,agriculture, fishing,industry,pollution,development,recreation,trespassing and traffic) have significant consequencesfor wildlife management. Several veterinary regulations also apply to wild animals. 4.1 Migratory birds The most important management tactics for pbpulations which visit severalcountriesduring the courseof a year are: regulationof hunting pressurein different countriesand conservationand management of breeding, moulting, restingand wintering localities. The managementof migratorybirdsis primarilya nationalresponsibility,but internationalcooperationis vital. In western Europeagreementsand conventionslikethe EECDirectiveof 1979 on the Conservationof Wild Birds,and the 1979 Berne Conventionareof major importance(Batten 1987). The Ramsar Conventionon Wetlands of International Importanceas Waterfowl Habitat in 1971 has alsocontributedsignificantly to improved management of migratory birds(Klemm 1979, Smart 1987). The 1979 Bonn Convention on the Conservation of Migratory Speciesof Wild Animalshas had a minimal 15 nina utredning018 effect becauseno bilateral or multilateral agreementshave been concludedto date (UNEP, pers.comm). In total 14 Europeancountrieshave signedthe Bonn Conventionin 1989. In 1988, 8 countrieswere partiesto the BarcelonaConvention concerning Mediterranean Specially Protected Areas (Grimmett & Jones1989). additional 20-30% may be wounded (Lampio 1982). Many duck populationsare probablyover-exploited(e.g. Harradine 1985, Tamisier 1985), demonstrating the importance of measuresfor regulatinghunting pressure.About 16% of the autumn population of geesein Europeis shot (Scott 1982). Following the recent introduction of strict regulationson goosehunting, most goosepopulationshave increased(e.g. Mehlum & Ogilvie 1984). The RamsarConventiondoesnot only promotethe conservation of certain listedwetlands, but also the "wiseuse"of all wetlands. A conferenceof the Contracting Partiesin 1987 adopted the following definitionof the conceptof "wiseuse" of wetlandsas "their sustainableutilizationfor the benefit of human kind in a way compatiblewith the naturalproperties of the ecosystem".The conferencerecognizedthat comprehensivenationalwetland policieswill be a long term process, and hence urged that immediate action should be taken to stimulatewiseuse(IWRB,pers.comm.). (b) Habitat management.- The ICBP(International Council for Bird Preservation)and the IWRB(InternationalWaterfowl and Wetland ResearchBureau)have worked out criteria for internationallyimportant bird areas(see Scott 1980). These criteria mainly apply to waders,waterfowl and birds passing through "bottle-necks"during migration. Registrationof significantwetland areashas been carriedout in Europeover severaldecades,e.g. by the AQUA project(Luther & Rzoska1971). The first publishedsurveyof western Europeincluded 15 countriesand 500 different areas(Scott 1980). The IWRBand the ICPBhave continued this work often commissionedby the EEC. By 1986, 11 countries remainedto be investigated,and only short listsof internationally significant areas were compiled for an additional 25 countries(ICBP & IWRB1987). Therefore a three year program, designedto cover all of Europe,was started in 1987, and a comprehensivereview has already been published (Grimmett & Jones1989). Management of bird specieswhich breed in Europeand migrate to other partsof the world, cannot be regardedmerely from a Europeanperspective.Hence,work hasstartedto produce an agreement under the Bonn Conventionfor western Palearcticwaterfowl, but it hasbeen recognizedthat it will be difficult to develop such a management plan (UNEP, pers. comm.). (a) Hunting regulations.- Despitethe availabilityof adequate informationon migration routesof mostwetland birds,hunting pressureis not regulatedalong European"flyways",such as is the case in North America (Scott 1982, Piersmaet al. 1987, Boyd& Pirot 1989). One reasonmay be that hunting statisticson relevantspeciesare lackingfor severalcountries (seeBertelsen& Simonsen1986). A large number of wetland reserveshave been established, many of them as Ramsarsites. Some of these have been createdwith internationalhelp. For examplethe World Wide Fund for Nature (WWF) has contributed to the purchaseof largewetland areasat LasMarismasin Spain. Internationalagreementson the prohibitionof non-selective trappingmethodslikenetsand baitedtrapshavebeena major stepforward. However,in severalcountries,netsare stillused to catchmigratorybirds(Bertelsen& Simonsen1976). The annualnetcatchof birdsin Italyisestimatedat 320,000 individuals,while statisticsfor Franceare more than one millionbirds, most of which are larks(Alaudidae).A "guestimate"done for the standingcomtnittee of the BerneConvention(CE 1986), indicatedthat more than 100 millionpasserinebirdswere annuallycaughtin Europe(includingCyprus),mostof them illegally.Alsoindiscriminateshootingof birdstakesplacein many countries,e.g. in Malta (CIC, pers.comm.). 4.2 Resident small game Populationswhich staywithin the boundariesof one country throughout the year are here regardedas resident.However, some indMduals may crossbordersto neighbouring countries, or engage in short migrationswithin their own country. The following is a discussionof measurescarried out by private individualsor organizationsto assistlocalwildlife populations.Suchaction may take placeon private, common and state property. lt is not imposed by the government, but may be regulatedby legislationor encouragedby statefunding. National regulationof hunting pressureon migratorybirdsis mainly enforcedthrough closedand hunting seasons.In recent years,daily or annualbag limitshave been introducedin somecountries(seeLampio1983). Many handbooks describedifferent managernent practices (e.g. Coles1971), but little is knoWnabout their application. Leopold (1933) mentions the following major subjects:es- About 45% of the autumn population of Europeanducksis estimatedshot during the hunting season(Scott 1982). An 16 nina utredning018 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. tablishment of game reserves,control of disease,hunting, predators,food, water and cover, and introductions.These practicesare alsorelevantin Europetoday: ln the early 1900's, predator controlwas one of the most important methods for helping small game populations. Predatorcontrolwas encouragedby the bounty system.The populationsizeof many predator speciesdeclineddrastically (Hagen 1952, Bijleveld1974, Newton 1979). The purpose of a game reserveis to produce a surplus populationin protected areas,which may migrate into nearby areaswhere hunting is permitted. Thissystemis not common in Europe,but 86 game reserveshave been established in Denmark for similar purposes (Jepsen 1985). National parksand nature reservesmay also partly serve similar purposes,but hunting may be permitted within some national parks,e.g. in Norway. Modern attitudestoward predator control are influencedby the followingconditions:1) Protectionof birdsof prey isgiven high priority.The most effectivemeansof control(poison and traps) are most often illegal. All raptors and owls are protected in most countries. 2) Researchhas shown that predators reduce populations of harvestable game (e.g. Strandgaard Asferg 1980, Korsch 1985, Potts 1986, Marcström et al. 1988, 1989). On the other hand, some studieson the effectsof predator control are not conclusive (Göransson& Loman 1978, Parker1984). 3) Predatorcontrol and in particular applying to specieslike the red fox (Vulpes vulpes) and crows (Corvidae) which may eat eggs and young, remainsan important aspectof game management in many countries, e.g. in Great Britain (Hudson Rands1988). Hudson(1986) suggestsmethodsfor reducingthe abundance of nematodesin Scottishred grouse(Lagopus lagopus scoticus), and for exterminatingticksresponsiblefor spreading the diseaselouping ill". Up till now these methodshave not, however, been used in any large-scaleway. In Sweden arcticfoxes (Alopex lagopus) have recentlybeen held in captivity for a period and treated for sarcopticmange. Small, adjoining, private estatesare often organized into management areas.This is an important management practice in Fennoscandia(e.g. Hamilton 1980). In Great Britain, syndicatesorganizeseveralsmallerestatesin large areas.The syndicateis responsiblefor hiring a gamekeeperand leasing hunting (e.g. Waddington 1958). Severalguidelineson the care and management of wetlandshave been published(e.g. GC 1981, Scott 1982, Lutz 1986). Only major themes are mentioned here: Vegetation like Carex, Phragmites and low bushes may be removed from inland waters by machinery or grazing animals.New wetlands may be created, and spoiledwetlands may be restored. Water levelsmay be regulated. Fertilitymay be increasedthrough the useof fertilizeror lime. Potentialbreeding habitat may be improved with nest boxes and artificial breeding islands. Food resourcesfor young may be increasedby controllingfish or lining nutrient poor poolswith straw. Open water areas may be maintained during winter. Eutrophicationlevels may be reduced by regulating husbandrymeans. Landownerswho use or leasehunting rights may regulate hunting pressure.The rate at which hunting yields are compensated for by lower natural mortality or increased production, determines the need for small game hunting controls(e.g. Kalchreuter1977, 1987). Among Scottishred grouse, reductionsin winter mortality may compensatefor high hunting pressure (Watson & Jenkins1968). Several population models have been devisedfor small game (e.g. Moss et al. 1979, Potts 1979, 1986), but little is known about sustainableharvestfor most species(Myrberget 1985, Hudson& Rands1988). When hunting pheasants,it may be wise to shoot more cocks than hens (Hill & Robertson 1988). Hedge planting,sowingwild meadowsand reducedpesticide usemay improve terrestrialhabitat (Coles1971, Ueckermann & Scholz 1981, Potts 1986). Heather (Calluna vulgaris) burning is beneficialto Scottishred grouse(Watson Miller 1976, Miller 1980). In Norway burning of dwarf birch (Betula nana) may be beneficialfor better game food spedes, suchasVaccinium spp. (e.g. Phillipset al. 1984). In severalareas including the Nordic countriesand parts of southern Europe,small game hunting pressureis only regulated by the length of the hunting seasons,the degree of hunting enthusiasm, and the number of personsthat are permitted to hunt. Blue hares(Lepus timidus) are-often fed with grain and hay (Aarnio & Vikberg 1980). Blackgrouse (Tetrao tetrix) in Finland are fed oats and wheat at 11,000 automaticfeedingstations situated on their display grounds (Marjakangas1985, Valkesjärvi6.1ljås 1989). Resultsare unknown (Willebrand 1988). In some southern countrieswhere hunting rights are free, the hunting pressureon smallgame hasincreasedrapidly in later years, so that many stocksseem to be overexploited. This may also be a consequenceof an increasednumber of gunsin some of thesecountries. In many countries,large numbersof galliformesand mallardsand other animalsare introducedto provideshortterm 17 nina utredning018 Table2.

Small passerinesmay also damage gardens and farmland (e.g. Bieber & Meylan 1984, Tahon 1985, O'Connor & Shrubb1986). excesspopulationsfor hunting (Table 2). The pheasant is the specieswhich is most often re-stocked.The birdsare frequently hybridizationof the subspeciescolchicus, torquatus and mongolicus(G. Göranssonin Andersson1988). Releasedanimals are either raised in captivity or originate from wild living populationsin other areasor countries.The latter type of re-stockingis common in Italy, where at least 800,000 individualsare annually imported for introductim, including 300,000 brown hares at a cost of 35 million U.S. dollars.Stockingof ptarmigan, capercaillie,and blue hare in Scandinaviahave not been of particularsignificancefor the existing indigenouspopulations(e.g. Lindlöf 1979). On the other hand, introductionsof haresto Norwegian coastalislandswith no previoushare population,have been quite successful(Huseby& Bø 1985). On the other hand, it is important to reduce lossesof birds and mammals due to agriculture machinery and practices. Small changes in agricultural and forestry practicessometimes help to avoid uneccessarynegative consequencesfor wildlife populations. Lessintensive use on the outskirtsof crops, may reduce the negative effectsof pesticideson the food of specieslike pheasantsand the grey partridge (e.g. Strandgaard1985, Potts1986, Rands1986). The capercaillie is adapted to primaryforesthabitat, and slightchangesin forestrypracticescould be beneficial,without resultingin larger economic lossesfor the landowner (Wegge 1984). Norwegian forestry authoritiesnow adviseall forest owners to include wildlife management plans in their general forestry plans(see alsoFalck& Mysterud 1988). It is also possibleto take better care of wildlife in cities and other urban areas (e.g. Gerell1982). Large-scalere-stockingsof small game have been criticized for severalreasons.Many introducedanimalsdie prior to the startof the huntingseason(Mikkelsen1986, Potts1986, Robertson & Whelan 1987), and introductionsmay lead to increasedexploitationof natural populations.Introduced animals may alsoinfluencethe genetic composition,behaviour and reproductivecapacity of the natural population (Hill & Robertson1986, 1987, 1988). Experiencefrom many countrieshas demonstrated the efficiency of information campaignsin influencing public attitudes to multiple use of habitats. The best resultsare obtained when information is spread by respected organizationsand individualsactivelyengaged in agriculture and forestry. (i) In many casessmallgame productionis economicallysubordinate to most other activitiesinvoMng natural habitats, and game management should be seen as part of multiple useschemesfor habitat. Firstly,game populationsshould be managedto avoiddamage to forests,cropsand pasture(e.g. 18 nina utredning018 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. 4.3 Big game hunting noscandia outside Fen- Great Britainare estimatedby field sightingand habitatquality (Prior1987). Poachingis a problem in some areas,e.g. in Ireland. In Ireland most (78%) of the forestsare owned by the state(FACE 1986). Most Irishfarms are small, 10-20 ha, and the hunting rightsare generallyheld by hunting clubs.About 5-600 hunting licensesfor deer with no restrictionon the numberspermitted to shoot, are issuedannually by the Wildlife Service (ForestSzWildlifeService1986 a, b). Only in Denmark, Ireland and Great Britain(e.g. Fog 1983, Prior 1987) may landowners themselvesfreely determine how many deer they shallshoot(Figure 1). Harvestingof red deer on private estatesin Great Britainis regulatedaccording to advice given by "The Red Deer Commissions"(Nahlik 1974, Miller 1981). The sizesof the roe deer populationsin Although the Danish owners themselvesdecide how many deer they want to shoot, they have a duty to ascertainthat deer do not damage agriculture in nearby areas, e.g. they can be forced to put up deer fences.To prevent damage to forestryby red deer, the owners may demand that the deer population must be decimatecLNo compensationis paid by the state for big game damage, but the state may subsidize plantingsfor managementpurposes. In Portugal,southernItaly and Greece,deer are almostcompletely protected(e.g. Bugalhoet al. 1986), and in the European part of Turkey,the deer is totally protected (Anonymus 1987, Serez 1990). In some cantons in Switzerlandand in north-westItaly the harvestis controlledby licensesonly. In Iceland, the Netherlands, Belgium (since 1989), Luxembourgh and Francethe harvestis controlled by licenseand hunting ground ownership, accordingto somewhatvarying systems(Haaften 1986, Gill 1988). For example, in Iceland central authoritiesdetermine the numbersof reindeerwhich may be shot, and municipalityauthoritiesauthorize hunters to do the culling.In Spain, ICONA (Instituto Nacionalpara la Conservacionde la Naturaleza) has the authority to regulate the frequencyof drive huntson privateland (Gill 1988).

The system is basedupon hunting traditionsfrom the 1800's (Raesfelt 1898, Bubenik1976), and was made obligatoryby law in Germanyin 1934 (Ueckermann1984). A descriptionof (a) red deer management in West Germany and (b) supplementaryinformation on other big game speciesis usedto illustratethe methodsemployed in the "territory"system.(The systemis alsoappliedto smallgame populations). Hunting territoriesin West Germanymustcomprisean area of 75-1000 hectares(DJV 1987). Territoriesof 75-150 hectaresare managed by landowners. Larger territoriesare managed by a hunting federation, under the leadershipof a committee composedof local landownersand municipalofficials. There are approximatdy 50,000 hunting territoriesin West Germany. nina utredning018 During a visitto Germanyin the 1930's, Aldo Leopold(1936) was impressedby the fact that in contrastto what he had observed in North America, Europeandeer lived on habitats stronglyinfluencedby humansand in the absenceof any effective predators.The main goal for deer management was to improvethe qualityof trophies,i.e. stag antlers.The situation today remainslargelythe same. - A harvestplan, which attemptsto maintain an equal number of malesand females,is approvedby a councilappointed for larger areas. Harvesting is controlled according to predetermined criteria on the sex and age distributionof the hunting yield (Figure 2). The optimum sizeof the trophy is the main objectiveof regulatingthe age distribution(Drechsler 1980), and hence is the main objectivedeterminingthe lifespanof the oldest stagsto be about 12 years. Formerly, major emphasiswas placed on harvestingweak or sickanimals (e.g. Newman 1979). Now apportionsare related to a certain extent to culling the weakestindividualsin each age class.Antlersand mandiblesare displayedat obligatoryannual exhibitions to ensure that the harvesting program for malesisfollowed. (a) Red deer.- According to Ueckermann (1960, 1986a, 1987), Gottschalk(1972), Bubenik (1976, 1989), Wagenknecht (1981) and Jelinek(1986), the purposesof red deer management are: 1) to establishpopulationsin all suitable habitat, 2) to regulate populationsin accordancewith other economic interests,such as forestry,farming, and to avoid trafficcollisions,and 3) to increasethe carryingcapacityand the quality (trophies)of the game yield. The following main measuresare usedto obtain thesegoals: - Feedingconditions are improved to increasethe carrying capacityof a territory and the quality of individualanimals (Ueckerman & Scholtz 1971). During the winter, different kinds of fodder are made accessible(Onderscheka 1986, Ueckermann1986b), preferablyto cover 50-75% of nutritional requirements(Ueckermann1971). Placementof feeding stationsaids controlling areasinhabited by deer during the winter, thereby reducing damage to vulnerable forest areas. - Carryingcapacityof the terrainshouldbe classifiedby registering borderzones,pasture,soilquality, and forestcomposition according to a system developed by Ueckermann (1955). The desiredspring population is set at 1.5-2.5 deer per km2 dependingon the carryingcapacityof the territory. Densitiesmay be increasedto 4 red deer per km2 by usingartificialfeeding, and decreasedif other speciesof deer occurin the territory. - Practicalmeasuresare employed to preventforest damage and include1) fencingof particularlyvulnerableforestsuccession stages,and 2) protection of certain trees through the use of chemical or mechanicalrepellents(e.g. Ueckermann 1960, 1981, Reimoser1986). Reddeer inflictthe most damage to treesin Europe(Ueckermann1987). - The spring population is estimated by counting deer at feeding stationsand through tracking. Individualanimalsare alsoidentified in some areas.Harvestableproductionis estimated as 65-70% of all adult hinds in the population as of April 1. •• • •• •• • • • o • • • • • 2• 1 • 9 • • , 8 • 7 6 • 5 4 3 2 1 0 • • • 6• • • 5 4 3 2 1 0 • • • • • • 20 • • ••••• •• • •• • • •• • Figure2 Above:Age compositionof an idealisedred deerpopulationof 100 individualsApril 1 in West Germany.

However,in many areas,e.g. in EastGermany the huntersexperiencegreat difficultiesin followingthe'recommendedplan (Briedermannet al. 1986). Experimentshave been conducted in the Alps to protect deer from disturbanceby touristsand to reduceforestdamage, by fencing deer in prime habitat during the winter (Gossow Stadlmann1985). Diseasecontrol is one aspectof the "territory" systemwhere in some areas medicine is mixed with food at feeding stationsto combat lung and other parasites (e.g. Spenik1985). into over-huntedareas.Populationdensityand habitat quality may affectreproductionratesof roe deer (Loudon1987). Fallowand sikadeer (Sika nippon) are managed in principally the sameway as red and roe deer (see e.g. Ninov 1990, Rumohr-Rundhof 1990). Higher percentages of these exotic bopulationsare, however, often raisedin captivityor under semi-naturalconditions. Wild boarsin Central Europeare also managed accordingto the territorysystem(Ueckermann1977, Briedermann1986). A number correspondingto 100-200% of the springpopulation isculled, and the averageis 140-150%. Economiccarrying capacityis 0.5 -1.5 wild boarsper km2. Estimatingpopulationsizeisdifficult,and in some casesculling is plannedon the basisof the extent of crop damage, which isoften extensive (Ueckerman1981, Briedermann1986). In Turkey, wild boars may be hunted year round (Anonymus 1987, Serez 1990). Many countrieshave recentlystartedto realizethat red deer and other cervidsare not countable, although their hunting lawsand regulationsassumethat they are (Gill 1988). Counting deer is especiallydifficultin forestterrain (Gossow1976). Thereforepopulationnumbersare often underestimated,and underexploited(Gill 1986). Somepopulationsmay alsobe intentionally underestimatedor overestimated.The sex of the animalshotisnot alwayscorrectlyreported. Management principlesfor chamois (Rupicapra rUpicapra), mouflon (Ovis aries) and ibex (Capra ibex) are similarto those for other ungulates (Wotschikovsky1977, Schröder 1985). However,these speciesoften occupy isolatedand remote habitat, and local management traditions play an important role. One of the goalsof management is to preserve the characteristicsof different sub-species.As an example, there are eight sub-speciesof chamoisin Europe. However, mostre-introductionshaveonly involvedanimalswhich originated from the alpine sub-species(rupicapra), even within the distributionalrange of other sub-species(Lovari 1984). Muflon is alsooften kept under semi-wildconditions,e.g. in the Netherlands(Litjenset al. 1989). There are also severalfundamental argumentsagainstusing this system.Bubenik(1970, 1986) statedthat the harvesting program does not account for population social structure. The systemmay also reduce genetic variation (Lang 1986). Bobeket al. (1990) claim that the influenceon trophy quality obtained through genetic changes induced by selective shooting of stags is lesspronounced than effectson antler sizefrom varyingpopulationdensityand habitatquality. Some opponents contend that the program gives greater precedenceto the detailed desiresof hunters,than to more _generallong-term goals (e.g. Wotschikowskiet al. 1986). It also discriminatesbetween the common and the wealthy hunter (Bubenik 1989). There is an increasingpolarization between hunting interestsand those of environrnentalprotection (Wolfe & Berg1988). 4.4 Big game in the Fennoscandia The following.wild deer speciesare found in Fennoscandia: moose, red deer, roe deer, fallow deer, reindeerand whitetailed deer (Odocoileus virginianus) (only in Finland).Harvest planningoften tendsto keepstocksbelow the ecologicalcarryingcapacityof a given area. Significantfactorsin determining the "economicalcarryingcapacity"of an area are damages causedby deer to agricultureand forestry,and accidents on roadsand railwaysinvolvingdeer (e.g. Stensaas1989). (b) Other species.-In centraland easternEuropethe "territory" systemusedfor hunting roe deer is basicallythe same as for red deer (K8nig 1982, 1983, Ueckermann 1982). The number of animalsharvestedin prime areasmay be equal to the springpopulationof adult females,while only 70-90% of the same figure is taken in poorer habitat. Harvestingplans involvea pre-determinedsexand age distribution(seeFigure 2). At least 110 000 roe deer are killed by automobiletraffic in West Germany and 60 000 by agriculturalmachinery(DJV 1,987). In contrastto the red deer, the roe deer populationis regulatedby socialmechanisms(Strandgaard1972), leading to an influx of animalsfrom areaswith lesshunting pressure Management of big game in Fennoscandiamay be saidto belong to a "territory"system (Bubenik 1989), but many practical measuresare different from those used in Central Europe.Althoughthere are geographicand specificvariations within Fennoscandiain practicalmeasuresusedwhen hunting quotas are set, the general procedure is as follows:The numberof hunting licensesissuedfor deer and often alsothe quota compositionof the yield isdecided by regionalauthori21 nina utredning018 ties.The number of licensesissuedis determined by the size of the population and the area. Landownersset the actual boundariesof hunting terrains,providedthey control an area which is at least equal to the size required for one license. They may sell their licensesif they wish to do so. One problem arisinghere is that the price in some casesis very high, up to 300 US dollar for one roe deer in Norway (Hagen 1989). cerningthe number, age and sexof animalsobservedduring the hunt, the "Moose seen" scheme (e.g. Pedersenet al. 1988). Most of thiswork hasbeen voluntary. Until recently,the mooseyield in all three countriesincreased as a resultof controlled harvestingand habitat improvement (Figure 3). Hunting is the greatestcauseof mortalityamong Nordic moose, and it is therefore possibleto calculatethe populationstructurewhich is conduciveto optirnal calf production (e.g. Stålfelt 1966). Harvestingis mainly aimed at calves,yearlingsand bulls,whereasreproductivefemalesare savedto a varyingextent. Thistactic resultsin highercalf production relativeto the total winter population.One problem with thesecalculationsis that they assumea fixed number of mooseafter hunting. This meansthat no considerationistaken to the fact that different populationcategoriesdo not eat equal amountsof winter food. The following examples are described:(a) management of the mooseand (b) modificationsapplyingto other species. (a) Moose.- The purposeof moosemanagementis to restrict the number of moosein order to reducedamage to forestry, crops and traffic to an acceptablelevel, and to manipulate population structure and size to obtain optimal hunting yields(Myrberget 1979, Rificker& Ståffelt1986, Haagenrud et al. 1988). The interestof trophy huntersassumesa low priority. Hunting quotas are determined by county administratorswho cooperatewith localrepresentatives.Fixedlimitsfor moosedensityin Finlandvary between 0.5 and 4 animalsper km2 (Nygren 1984), but such limits do not exist in Sweden and Norway. 150000 Only registered"moosehunting areas"are open for licensed hunting. One exception is the right to shoot an unlicensed number of moose calvesduring a short open seasonin unregisteredareasof Sweden. Hunting areaswithin a particular municipalityare in most casesdefined as belonging to the same "moosemanagementdistrict".However,this definition only inadequatelyconsidersecologicalrealities. 100000 Sweden Finland 50000 Norway In Sweden, county administrationis divided into 23 areas, and playsa significantrole in the distributionof quotas. Provincial moose boards propose harvesting plans for each moosedistrict.The systemissimilarin Finland. 25000 1945 In Norway, quota permitsare issuedby the County Governor according to a "minimum area" for each animal permitted shot. The size of quotas is largely based on experiencesin earlieryears,yield statistics,and simulationmodelsinvolving the size of the yield in previousyears and the number of mooseobservedduring the previoushunting season(e.g. Jaren 1988, Pedersenet al. 1988). Quotas are assignedto each landowner by a municipalgame board, in accordancewith minimum areas. 1950 1955 1960 1965 1970 1975 1980 1985 Figure3 Harvestof moosein Fennoscandia1945-86. (Mainly after Haagenrudet al. 1988). The winter population of moose has alsoincreasedin many areas. In some Scandinaviandistrictsthe moose population has reachedan abundancewhich exceedscarryingcapacity, which has led to unacceptablyhigh levelsof damage in recent years.Reducedreproductionhasbeen reportedin some populations. Deliberate action has been taken to reduce some of these populations,but considerabledoubt remains asto how thissituationshouldbe treated (e.g. Jaren1988). Management in Finland includessystematicinvestigationof availablepasture land and forest damage. In Finland, compensation is paid for damage to forestry and agriculture, whereasin Norway and Sweden only damage to agriculture may be compensatedfor. In Sweden, many populationsare counted from a helicopteror an airplane. Moose huntersin all three countriesare provided with a questionnaire,con- (b) Other species.-Practicalmeasuresusedto set quotas are largelythe same as for moose. However, non-licensedhunt22 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 duce reindeernumbersthrough intensivehunting, sothat the sizesof populatlonsandyieldsfluctuatefrom year to year. ing of roe and fallow deer is also permitted during an open seasonin Sweden(Nordell & Weinberg 1983). In fact, in later yearsmost roe deer are felled by this system.In Finland,roe deer hunting isallowedonly on the Åland Islands. Roedeer and red deer are difficultto count, and hunting statisticsfor roe deer in Norway yield figureswhich are far too low (Myrberget 1988). Reddeer and reindeeronly give birth to one calf, and the effectof age-specificselectiveharvesting is not asgreat asfor the moose.It is, however, alsofor these species important to ascertainthat hunting leads to few motherlesscalves: Roedeer populationsare in this northern area mainly limited by climaticfactorsand snow conditions(e.g. Hjeljord1980), and wild reindeerdo little damage. Therefore,ecologicalcarrying capacity is the primary limiting factor for population levelsof thesespeciesin a given area (Stensaas1989). In Scandinaviasnow depths may increasemortality among roe deer during particularlyhard winters(Hjeljord 1980), and supplementaryfeeding is reccommendedunder such conditions. Roe deer feeding programs are common in Sweden, but little is known about their effectiveness(Sandberg1985). Wild reindeerare only hunted in southernNorway. Management units are comprisedof about 25 more or lessnaturally separatedmountain ranges,each usuallymade up of several municipalities (Krafft 1981). Reindeer management relies even more heavily upon information about the relationship between population production and density, and available winter food resources(see Figure 4, Skogland1986), than other Europeanbig game management schemes.The population iscounted and populationstructureand habitat quality are monitoredat 1-5 year intervals. The development of a small huntable population of wild boarshas only been permitted in the Stockholmarea, while boarsin all other partsof Swedenare treated as "pests".The same is the case in Finland. It has not been possible,however, to count and controlthe Swedishpopulationaccording to plans. In several reindeer areas there are continual difficultiesin maintaining suitablewinter populations.One reasonis that herdsmay wander long distancesin responseto weather conditions,and it isthen difficultto organizeeffectivehunting in an entire area. Sometimesit is necessaryto deliberatelyre- 4.5 14 c 30 12 10 20 8 c 10 4 1 2 3 predators There is no common systemfor the management of brown bear, wolf, wolverine(Gulo gulo) and lynx (Lynx lynx) in Europe. However,the objectiveof management in many countries is similar, namely to maintain "viable"populations(see Soulé1987) responsiblefor acceptablelevelsof damage. The most seriousdamage is to livestockand semi-domesticreindeer, but locally killingof big game and damage on honey bee hives are taken into consideration (e.g. Sørensenin press). 16 cl) Large mammalian Thesespecieswere formerlyheavilypersecuted,and bounties were common. Today, most populationsare small, and are largelyprotectedagainsthunting. However,for some species and areas, licensehunting is permitted, e.g. in Sweden. In other areasan open seasonschemecontrolshunting, e.g. on lynx in Norway. 3 Norway is one of severalcountrieswhich have worked out a national plan for management of large predatory species (Vaag 1987). Registrationsare a major part of this plan (Sørensenet al. 1984). The term "viable"refersto any population where the probabilityof decline over a 20 year period is lessthan 15% (see population modelling by Stenseth& Steen 1987). For thesespecies,which occur in low densities and uselarge home ranges,cooperationbetween neighbouring countriesis imperativeto ensuretheir conservation(e.g. Mysterud& Falck1989). 4 Populationdensity (n/km2) Figure4 Estimatedannual productivity curvesfor Norwegian reindeer in terms of numerical abundance (dotted curve) and biomass (full curve). The arrows indicate the densitiesat which maximum sustainable yield is obtained. (After Skogland 1986). 23 ninautredning018 5 Game population distribution, status and harvest To illustrate management of populationstreated as game, the management of bearsin Yugoslaviamay serveas an example (following Cicnjak& Ruff 1990): In one of the republics(Macedonia) the hunting is not regulatedand bearsmay be hunted year-around. In the other five republicsbearsare carefullymanaged and hunted. Management methodsusually includeregulatedbaiting/feedingsites.Systernaticobservations of bear visitsat feeding stationsare used to estimate population size. In Slovenia, management includes habitat protectionfor areasknown to be important for denning, and orchardsare planted to provide additionalfoods. The length of the hunting seasonvaries between republics,but usually begins in early September or October and ends in mid- or late May. Fearof the wolf isa common featureof many human cultures (e.g. Naess & Mysterud 1987). Although there are a few known caseswhere escapedcaptivewolves,or wolvesinfected with rabieshave attackedand killed humans(e.g. Pimlott 1975), there are no documentedcasesof attackson humans by healthywolvesin recent times. On the other hand, more examplesexist of humans being killed by brown bears(e.g. Cicnjak& Ruff1990). Becauseof variationsin natural conditionsand differencesin hunting regulations,the number of game speciesin Europeis high. In Sweden, approximately 150 speciesare considered game (SOU 1983). At least 100 bird speciesare legallyhunted in one or another western Europeancountry (e.g. Bertelsen & Simonsen1986). Fewer speciesare hunted in Great Britain,the Nordiccountriesand easternEurope.Asan example, in addition to ducks, 29 bird speciesmay be hunted in Hungary, but some speciesmay also be shot by speciallicense. • In the past the polar bear was heavily hunted on Svalbard (Larsen1972). The speciesis now protectedthrough the InternationalPolarBearAgreementof 1973 (seeStirling1986). One man hasbeen killedby polarbearson Svalbardin recent years,and a few bearshave been shotin selfprotection. A relativelynew surveyof the statusof all Europeanbird spe& Sharrock1985). I am not cieshasbeenworkedout aware of any correspondingsurveyon mammals, but handbooks such as those by Brink (1968) and Niethammer & Krapp(1982) givegeneraldata on distribution.-Onlythe status and yield of the most important game speciesare describedin this paper. 5.1 Waterfowl The mallard is the most important game speciesamong ducks(see Table 3). However, probablyabout one half of all mallardsshot have been raisedin captivity.Other duck speciesshot in any numbersare teal (Anas crecca), garganey(A. querquedula) and wigeon (A. penelope). Most of the geese hunted are the greylag (Anser anser), pink footed goose (A. brachyrhynchos) (mostly in Great Britain) and the whitefronted goose (A. albifrons). The population statisticsmust, however, be usedwith great caution, becausemany uncertain data and errorsmay be included. Some of the data are certainlyalsoout-dated. Many of the management principlesusedon large terrestrial predatorsalsoapply to seals(e.g. Bonner1975). A frequently discussedissue is the transmissionof nematode parasites from sealsto fish (e.g. Helgadottiret al. 1985). Suchparasites may be of economicimportancein commercialfisheries,and hence lead to sealculling programs,e.g. in Norway (Bjørge 1987, Wiig 1988a). The majorityof swan,geese and duck specieshave increased in numbersin recentyears(Mehlum & Ogilvie 1984, Nilsson & Fog 1984, Kalchreuter1987). However,there are some exceptions to this rule, e.g. light-bellied brent geese (Branta bernicla hrota) (Madsen 1987). Introductions of Canada geese (B. canadensis) have resulted in large populations which are hu'ritedin Scandinaviaand Great Britain(Owen et al. 1984, Heggberget1987). In addition, more than one million coots (Fulica atra), lapwings (Vanellus vanellus), woodcocks (Scolopax rusticola) and common snipes(Gallinago gallinago) are killed. Significant numbersof jack snipe (Lymnocryptes minimus), moorhen (Gallinula chloropus) and curlews (Numenius arquata) 24 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 Table 3.

Out-dated data 5.2 Other small game species are also shot (Hepburn 1984, Sheddon 1986). Statisticson hunting of smallerwaders do not distinguishbetween species. Several million gulls (Larus spp.) are shot. Auks and other diving seabirdsare or were popular game in northern areas. The brown hare and the rabbit are the most abundant of all mammals hunted, and 10 million of each speciesare probably killed annually, although few statisticsare available. Rabbit populationsthroughout Europedeclined rapidly after the deliberate introduction of myxomatosis in France in 1952 (Moore 1987). In some partsof Great Britain,the population was reduced by 99% (Lever 1985). Numbers of rabbits have increased somewhat since. In northern Europe, Scotland and the Alps, the brown hare is replaced by the blue hare. Earlierthe red squirrel was commonly hunted. The alpine marmot (Marmota marmota) is locally hunted in the Alps. Accordingto Nowak (1974), the numbersof waterfowl killed per unit area in France,Great Britain,Denmark and the Aaland islands(Finland)are particularlyhigh. However,hunting statisticsare lackingfor some countries(see heading Table 3). and some statisticsmay underestimatethe numbersshot (e.g. Göransson& Larsson1987). 25 ninautredning018 The beaverwas almostcompletelyexterminatedin Europein the'last century. Protectionmeasuresand introductionshave led to improvements.Today there are at least50,000 individuals in Scandinavia,where the speciesis shot and trapped (e.g. Myrberget1987). The Canadianbeaver(Castor canadensis) hasbeen introducedto Finland(Lahti& Helminen1974). resultof previousover-exploitation(Strandgaard1979). Roe deer do not occur in Ireland and Iceland. To establishroe deer in more areasin Finland, some animals have been releasedfrom captivityin recentyears(Vikberg1988). There are more than one million red deer, and 300,000 are annually killed (in Great Britain 50,000 annually, most of them in Scotland).Some deer specieshave been introduced to Europe (see Lever 1985), and there are 200,000 fallow deer, 40,000 white-tailed deer (see Pulliainen Sz Sulkava 1986) and 20,000 sikadeer. A smallsemi-wild populationof axisdeer (Cervus axis) is found in Yugoslavia,while Chinese water deer (Hydropbtes inennis) and muntjac (Muntiacus muntjac) occur in Great Britain. Sika deer and red deer hybridsare found in many areason the BritishIsles(Harrington 1982, Ratcliffe1987). Anotherintroducedspeciesisthe grey squirrel(Sciurus carolinensis) on the BritishIsles(Lever 1985). Escapingfrom captivity, populationsof coypiu(Myocastor coypus) have been establishedin Great Britain (now erradicated),central Europe and Italy (Lever 1985). Muscrats(Ondatra zibethicus) have also escapedfrom fur farms since 1905, and are today regarded as pests in large areas of Europe (Popelin 1969, Troostwijk1976, Danell 1977). The woodpigeon (Columba palumbus) is among the most often killed small game speciesin Europe,and more than 12 million are shot in Great Britainalone (Bertelsen& Simonsen 1986), and 6 millionin France(L'OfficeNationalde la Chasse 1986). At least 20 million pheasantsare killed (possibly10 millionin Great Britainand 6.5 millionin France).Statisticsindicate that more than one million individualsof each of the followingspeciesare killedannually:grey partridge(2 million in Francealone), red-legged partridge (Alectoris rufa) (more than 1.1 million in France), and willow ptarmigan and red grouse(Lagopus lagopus) on the BritishIslesand in Fennoscandia. In addition, millionsof thrushes(Turdus spp.) including 15-25 million in France,crows(Corvidae)and small passerinesare killed.In Francemore than half a millioncommon quails(Corturnix corturnix) are shot. The moose is the most important big game speciesin Fennoscandia,where the population approaches500,000. Harvestingvariesconsiderably,and in recentyears150-225,000 havebeen killed(seeFigure 3). Norway, Svalbardincluded,is the only country supportinglarger populationsof wild reindeer (Reimerset al. 1980, Krafft 1981), but some smaller populationsare alsofound on Iceland(Thorrisson1980), and in Finland(Sulkava1980, Heikuraet al. 1985) where they are protectedagainsthunting. Yieldsvary considerablyon mainland Norway, 7-15,000 annually. Followingre-introductions,chamois are now found in most central and southern Europeancountries.The total population is about 350,000, and 75,000 are harvested,most of them (25,000) in Austria. Previously, mouflon were only found on Corsicaand Sardinia(Spagnesi& Appolonio1985). Today there are more than 70,000 individuals spread throughout severalcountries(Briedermannet al. 1989). Harvestinghasincreased,and 10,000 mouflon are annuallyshot. In the Alps,ibex originatefrom a small populationwhich surrived there about 100 years ago. At the presenttime there are more than 25,000 animals(Schröder1985). Grouseincludingthe capercaillie,blackgrouse(Tetrao tetrix), hazelgrouse(Tetrastes bonasia) and rockptarmigan(Lagopus mutus) are popular game in Fennoscandia.The rock ptarmigan isthe only-wild-livinggrousespecieson Icelandand Svalbard. Populationsof woodland grousein central Europehave sharplydeclined (e.g. Haarstick1985); the same is the case for blackgrouseon the BritishIsles(McKelvie1987). 5.3 Wild livingforest wisents(Europeanbison) were exterminated in the 1920's. Re-introductionsof individualssurvivingin captivity(Glover 1947, Krysiak1967), have resultedin a population of about two thousand animals in areas along the border between Polandand the SovietUnion, of which nearly half livewithin Poland. Big game The surveyof the abundanceof big game, givenin Table 4 is somewhat inadequate. Numbers have increased in some countriesafter the estimateswere made. The estimatesare not equallyaccurate,and the figuresare not alwayscomparable. In the majorityof casesstatisticsreferto the springpopulation, but someautumn populationsmay be included. The wild boar is found in most countrieson the continent. Numbersare very low in Finlandand Denmark.A smallpopulation hasbeen establishedin Sweden after escapesfrom capivity(Kristiansson1985). The wild boar is not found in Norway, on Iceland,or on the BritishIsles.The springpopulation approaches500,000 individualsand 400,000 animalsare annuallykilled(Bäumleret al. 1986). The most abundant speciesisthe roe deer of which there are more than 6 million.Two million are killedannually,most of them (700,000) in West Germany(DJV1987).

SoMe attempts have been made to re-introducethe lynx to Central Europe(Festeticset al. 1982). Small numbersof pardel lynx (Lynx pardina) occurin Spainand Portugal(e.g. Delibes 1984). Some hundred wolverineslive in Fennoscandia. The largestotter populationsare found in northern Norway and on the BritishIsles(Reutherand Festetics1980). The polar bearonly occurson Svalbard. Populationsof larger carnivoresare heavily reduced in Europe. The largest brown bear population of a maximum 8,000 animals livesin the Carpathian-Balkanarea (Sørensen in press).Some 1,500 bearslive in Fennoscandia,while isolated populationsarefound in Italy, Franceand Spain. A wolf populationwhich may compriseas many as4000 individuals,inhabitsthe Carpathian-Balkanregion (Mech 1982), and isolatedwolf populationsare found in Italy, Spain,Portugal and Norway/Sweden.Wolvesoccupyterritoryon the borders between Soviet Union and Poland (900) and Finland (lessthan 100), respectively. The common seal (Phoca vitulina) and the grey seal (Halichoerus grypus) are the most common sealspecies.In 1988 a great proportion of common sealswas killed by a virus(e.g. Anonymus1989a). Arcticsealsare common on Svalbard,and they are observedin other northernareasduring migrations. A residualpopulation of ringed seal (Phoca hispida) alsooccursin the BalticSea(JärvinenST. Varrio 1986). The entire population of lynx is unlikelyto be greater than 1,500 individuals,most of which are found in Fennoscandia, 27 nina utredning 018 The red fox is the most commonly hunted carnivore,and is found in most of Europeexcept Svalbard,Icelandand Crete. No combined statisticsare available, but the total number killedcertainlyexceedsone million.Numbersin Fennoscandia and Denmarkhavedrasticallydeclinedin recentyearsbecause of sarcopticmange (Lindström& Mörner 1985, Eis1989). The arcticfox occurson Svalbard,Iceland, and in Fennoscandia. The speciesis regarded asthreatened in Fennoscandia,while being covetedgame on Svalbard.The arcticfox is hunted on Icelandto curb actualor imagineddamagesto livestock. The potential estirnatedvalue of hunting of approximately 300 U.S.dollarsper hectaréforestfor landownersin England, is higher than the income from forestry. In EECcountries, hunting directly or indirectly creates 100,000 jobs (CE 1987a), and thesefiguresmay be doubled when accounting for all of Europe(Myrberget 1990). Hunting isthereloreof great socio-economicsignificance.1n many wayshuntingis alsoan important sourceof incomefor rural districts(CE 1987a). In eastern Europe, hunting yields must partly be sold to the government, and are exportedtO the international market. Hunting tourism is common in many of thesecountries(Bubenik1989). In suchcaseshunting alsoprocureswesterncurrency. Other small and medium-sized Europeancarnivoreswhich are harvestedare primarilythe pine marten (Martes martes), beech martin (Martes foina), polecat (Putoris putoris), stoat and badger (Meles meles). The raccoon(Procyon lotor) was introducedin West Germanyaround 1930-40. Largepopulations are found there today, and the specieshas spread to Franceand the Netherlands(Lever1985). The Americanmink (Mustela vison), which escaped from mink farms is now found in most of Europe.The poputationis probablygreatest in Scandinavia,the BritishIsles,and Iceland(e.g. Lever1985, Bevanger& Ålbu 1987). Populationsof raccoondog-(Nyctereutes procynoides) originating from introductionsin the Soviet Union, have spreadto mostof Europe.The speciesis particularly abundant in Finland where 60,000 animals are annuallykilled(Helle 6.1Kauhala1987). 5.5 Economic value of hunting In every country, venison and shot small game are legally saleable,but different regulationsmay restrictthe sale,e.g. in time (e.g. RSPB1989). A game meat draft directivehas been proposedwithin the EEC-countries,but this has been met with strong criticism,e.g. from UK (BASC1989). In Turkey, only meat of wild boarsmay be sold(Anonymus1987). Regulationsconcerningthe saleof meat and skinsof wildlife also apply to animalsfound dead, e.g. killed in traffic accidents. In Sweden, the possessorof a hunting right owns all wildlife found killed as long as he properly disposesof the carcass.However,somespeciesare designatedasthe property of "the crown" (Nordell 6.1Weinberg 1983). 1nNorway, all dead game which is not killed through legal hunting, is in principlethe property of the wildlife authorities.Hence, authorizationof comrnercialwildlifetaxidermistsis alsodone by wildlifeauthorities. The first-hand value of game killed in Europeoutside USSR around 1970, was calculatedto be about 100 million USdollars(Nlisslein1974). About 1985 the value had increasedto 700 million US dollars(Myrberget 1990). When the value of hunting is estimatedon the basisof annual hunting expenses,the figure may be about 3,500 milliondollars. 28 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 6 Challenges and special problems 1988, natural poisonousalgaes(Chrysochromulina polylepis) killedmost life in the littoralzone of Skagerrak;the causefor the algae floweringis not fully known (Dahl et al. 1989). Another threatenedseais the Mediterranean(e.g. Pastor1988), and severaldifferentorganizationsin the United Nationsratified an Action Planagainstpollutionin 1975 (e.g. CE 1987c, Saliba1988). To reduce marine pollutionin Europeanwaters many agreementsand conventionshave been signed, most recentlyat the SecondNorth SeaConferencein 1987, and in the Haaguein 1990. In common with the restof the world, natural habitatsin Europe are exposedto global threatsincludingpollution,reduction of the ozone layer, the greenhouseeffect and human overpopulation(e.g. Myers 1985, Brown 1990). Most of the land area of Europe has been altered by human activities, through agriculture,forestry,industry,housingdevelopment and transport (e.g. Goudie 1981). Here, we will examine some of the greatestthreatsto game in Europe,but alsodiscussa few lesssignificantproblems. 6.1 In the 1960's, attention was drawn to heavy metals,such as the useof alkylmercurycompoundsfor seed dressing(Borg et al. 1969). This problem was solvedby changingmethods. Many wetland birdsdie as the resultof poisoningfrom lead in shot (e.g. Danell 1980, Bløtekjær1988). Only Denmark has until 1989 introducedlimitationson the useof lead shot for hunting or marksmanshiptraining (Anonymus 19864. Deer are locallypoisonedby fluoridedischargesfrom industry (Borg 1978, Kierdorf& Kierdorf1990). Metalslikealuminium are releasedinto the ecosystembecauseof increasingacidity (Nyholm 1981). Long-term population effectsdue to nonlethal levelsof metal pollution are, however, poorly understood(e.g. Pedersen& Nybø 1989). Pollution Severalchemicalagentsand bondsare conveyedinto the environment to an extent which hasdirect or indirect negative consequencesfor game populations (e.g. Murton 1971). Some of these are metals, pesticidek PCB, ozone, and sulphur and nitrogenoxides. Acid rain representsthe most seriousimmediate threat. As early as around 1960, it was clear that sulfateions in precipitation killed invertebratesand fish in severalwatercourses.In Norway thousandsof lakesare now devoid of fish. Although sulfateemissionshave been reducedin recentyears,water remains acid becauseof increasingdischargesof nitrate ions (Fjeldstad1987). Accessto nourishmentis reducedfor game specieslivingon fishand invertebratesin many watercourses, but the total effect is poorly understood.On the other hand, increasedemissionof nitrogen may improve habitat quality for browsingspecieslike roe deer (Ellenberg1985) in some areas. Most environmentalpoisonsaffect game populationsin the form of reduced reproduction (Moore 1987). Reductionin the thicknessof egg shellsof many birdsof preyisone example (e.g. Cooke et al. 1982). PCBpollutionof the Balticand the North Sea is responsiblefor uteralfusionand reducedreproductionin seals(Helle & Stenman 1987). PCB may also be the causeof populationdeclinesin Europeanotter populations(Olsson& Sandegren1989). Pollutionmay render game meat unsuitablefor human consumption. It is a well known fact that large amountsof cadmium are absorbedin the liver and kidneysof some game species(e.g. Eisler1985, Frøslieet al. 1986). After the accident at Chernobylin 1986, concentrationsof radioactivityin game in Scandinaviawere high (e.g. Danell et al. 1987). Particularlyhigh concentrationsof up to 100,000 becquerellpr. kg wet weight, were demonstratedin wild reindeerin Norway (e.g. Skogland 1987, pers comm.). One may not rule out the possibilitythat these concentrationsare so high that they damage genetic materialin reindeer(Skogland& Espelien 1990). Although the causesare very complicated,acid rain and exhaust from autômobilesappear to contribute greatly to the increasingextent of forest damage (Hutchinson & Meema 1985, Schneider1986, Innes 1987). Damage is most severe in Czechoslovakiaand southern Poland. Extensiveand widespread forest dieback has been observed in seNieralother countriesin central Europe,and to a lesserdegree in Scandinavia(CE 1987b, Krauseet al. 1987). Acid rain affectsdeciduoustreesaswell asconiferousforest.Browsingby deer makes plantingof acid-resistanttree speciesdifficult(Szukiel1987). Oil spillagefrom shipsor land basedindustryhaskilledthousandsof seabirds,includingabout 100,000 birdsin Skagerrak durihg the winter of 1980/81 (Anker-Nilssenet al. 1981). Chemical treatment of oil-spill at sea may negativelyaffect the marine ecosystems(Zachariassen1989), but the effects on sea bird populationsare poorly known. In countrieslike Norway, environmentalimpact analysesare mandatory pre- Different types of pollution are carried by riversto the sea. The Baltic is renowned as the most polluted sea in Europe (e.g Lassig1987, Rapport1989). Wa-terfrom the Balticempties into Skagerrakand the North Sea, and along with pollution agentsfrom countriessurroundingthe North Sea hasaltered the ecologicalbalanceof the sea(e.g. Carlson1986). In 29 nina taredning018 requisitesto exploratory oil drilling at sea (Griffiths et al. 1987, Anker-Nilssen1988). cluding brown hare, grey partridge and pheasant(e.g. Frylestam et al. 1981, Potts 1986). Habitat lossand detoriation may interact with increasedpredation in driving the game populationsdownwards(Potts 1984). Severalwildlife species are killed by agriculturalmachinery,and this is probablythe main reason for the declines in populations of corncrake (Crex crex) (Cadbury& O'Meara 1985). International cooperation is vital in fighting pollution, and severalagreementsconcerning a variety of substancesfrom many regionshave been ratified. For example governments have agreed upon halving the pollution of the North Sea from 1985 to 1995. Statisticson dischargesof toxic wasteare regularlycollected (e.g. ECE 1987, OECD 1987). Prognosis concerning developments in pollution levels are being workedout (e.g. Alfsen& Glomsrød1986). To reduce the threat to traditional farming systems,and henceto many wildlifespecies,the EECin 1985 (EECRegulation 797/85) introduced the concept of "Environmentally SensitiveAreas"(ESA). This enables member States to pay farmers in "ESA"an annual premium per ha if they manage land in prescribedways to sustainwildlife. From 1987 "ESA" could be supportedalsoby EECbudgets. However, it is difficult to securemanagementto safeguardwildlife populations in "ESA"(Woods1989). National monitoring programs similar to those imposed in Sweden (Bernes1985) are imperative.Although game may be used as indicatorsof environmental pollution (e.g. Diamond & Filion1987, Stokesand Piekarz1987), no major European program on this kind of study has been initiated. A potential project is now being evaluated by the Statistical Commissionof the ECE(United Nations EconomicCommission for 'Europe). In many countries,pollutersare forced to payfor cleaningu-p. Central European moorland is particularly vulnerable, and only vestigealpopulationsof black grouse remain in these areas(Niewold & Nijland 1988). In Great Britainsheepgrazing has led to lossof rfioorland,and hence of lossof habitat suitableto many wildlife species,such as red grouse(Anderson & Yalden1981). 6.2 Human use of land and resources Modern forestrytechniqueseliminate important environmental nichesprovided by primary forest, and increasehabitat coarse-patchfragmentation (BurgessEz Sharpe 1981, Harris 1984, Ahlen et al. 1986, Ellenberg1987). Herbicidesremove low bushyvegetationwhich previouslyprovided nutrient resourcesfor game species(e.g. Lund-HøyeEtzGrønvold1988). The capercailliehassufferedmost from modern forestryfragmentation and lossof suitablehabitat, i.e. old forestswith an abundant ground layerof bilberry (Vaccinium myrtillus) (e.g. RolstadEzWegge 1987, in press,Klauset al. 1989, Gossowin press). On the other hand, browsing for moose and other cervidshas increasedconsiderably(e.g. Ahlen 1975, Adamic 1986b). Much of the natural environment in Europeis today either createdor heavilyinfluencedby human activity(e.g. Gossow 1985, Strandgaard1985). Some previouslyproductivegame habitats have become wildlife desertsbecauseof urbanization, industry, power development and road building, to mentiononly a few. In West Germany, one million hectaresof wildlife habitat were lost between 1953 and 1983, and today there are only 370 regionswith a 100 km2 area which have not been fragmented by development and road building. These figures correspondto about 15% of the entire area of West Germany. Through these areasthere are numerousfoot paths and ski,tracks. Recreationalactivity in forested regions has increasedby 500% between 1950 and 1980, in some areasby 1000%, e.g. seeVolk (1986) and CE(1987b). Tourism and outdoor recreationalsports have increased,resulting in greater disturbance of wildlife habitat (e.g. G6tmark 1989). Examplesare camping which affectsshoreline habitat for birds, and skiing in Central- Europe (Volk 1986). The pressurefrom tourism is particularlyheavyin the coastalzone of the Mediterranean(Saliba1988). Changes in methods employed by agricultureand forestry have had enormousconsequencesfor wildlife.About 50% of the entire area of Europeis exploitedfor agriculturalpurposes. Modern agricultureis characterizedby monoculture.The sizeof fields hasincreased.Chemicalsare usedto kill weeds, fungi and insects. Bushy vegetation around fields and in hedgesare removedand open ditchesand dams are filled in. Fertilizerdrains into watercourseswhich become eutrophic. Theseagriculturalpracticesaffectseveralgame species(Murton 1971, O'Connor & Shrubb 1986, Andersson1988), in- Fisherieshave reducedthe availablefood'for severalseabird species(Croxall et ai. 1984). Over-exploitation of herring (Clupeus harengus) is responsiblefor the decimationof puffin (Fratercula arctica) populationsalong parts of the Norwegian coast,where young puffin$have starvedto death since 1970 (Barrettet al. 1987). In 1987, the collapseof the capelin population(Mallotus villosus) in the BarentsSeahasled to near total exterminationof severalcoloniesof guillemot (Uria 30 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 aalge) on the Norwegiancoast(Vader et al. 1990). Drowning lated at 100 million dollars annually (DJV 1987). Big garrie collisionswith trains result in delays and inconveniencefor railwaypersonnel. in fishingnetsis a significantcauseof death for many seabird species,but accurate data is lacking. Harp seal (Pagophilus groenlandicus) populationshave alsobeen affectedby lackof food, as demonstrated by the massinvasionof sealsalong the coastof northern Norway during the winter of 1986/87. At least60,000 sealsdrowned in fishingnets(Wiig 1988b). A large numberof wildlife speciesmay causeconsiderablelocal damage, suchas is the casewith damagesto aquaculture by eiders,grey herons (Ardea cinerea), otters and seals(e.g. FAO 1989). Oystercatchers (Haematopus ostralegus) may harm Britishmusseland cocklefishing (Murton 1971). Beavers may by dam-building over-flow forest planting areas. Birds may be hazardousfor aircraft (e.g. Busnel& Giban 1968). Locallyeven honey buzzards(Pernis apivorus) may be persecutedfor harming bee hives(Dontshev1990). Many birdsare killedby power lines(e.g. Bevanger1988, Bevanger & Thingstad 1988). Big game and small game may be killed in large numbersby traffic (e.g. Ueckermann1964, Almkvistet aL 1980). Orienteering competitionsmay affect wildlife, particularly pregnant deer and calves (Sennstam 1974, Jeppesen1987). Game farming may transportdiseases and competewith wild livinggame speciesfor habitat. In UK there are at least10,000 red deer in farms, or parks,in West Germany (FRG) 25,000 fallow deer (Hansen 1988). Hydroelectricdevelopmenthasoften a negativeimpact on the habitats of many wildlife species(e.g. Bevanger & Thingstad 1986). One frequentlyemployed measureusedto reducedamage is reduction of population size for the species in question through increasedordinary hunting or special pest killing schemes(Putnam 1989). These measuresmay be effective providedthat they increasetotal mortality rates(e.g. Murton et al. 1974, Potts1981). However,control measuresmust be specificif they are not to damage more vulnerablespecies (Wright 1980). Official game management planning may reduce the effects of permanent encroachmenton game habitat. In Norway, maps indicating particularlyvulnerable wildlife areas have been worked out for the entire country. In 1985 a master plan was ratified for the use of Norwegian water resources and productionof electricpower. 6.3 Wildlife A problem arising may be that the speciesdoing damage is not alwaysclassifiedas game with an open hunting season. This means that they can only be killed after considerable damage hasalreadybeen observed,or in some casesonly by speciallyauthorized personell(e.g. RSPB1989). Threatened speciesdoing damage may only be killedon speciallicenseissued by local or central wildlife authorities.In certain such cases,the killing may be done regardlessof landowner or hunting rights. For example, in Norway, individual brown bearsand wolverineswhich are supposedto be responsible for considerabledamage to livestockmay be killedby specially appointed teams of hunterswithin the bordersof a given municipality. damage Wildlife may alsocauseproblems.Darnagesto forestry,agriculture and animal husbandryhavealreadybeen mentioned. A "pest"is commonly defined as "any speciesor population which by its activitiesconflictswith man'sintereststo a level where the damage caused becomes of economic significance"(Putnam 1989). However,the matter of when this level of significanceis reachedis largelyevaluatedon a subjective basis(e.g. Troostwijk1976). The activitycausingconflict may be part of the normal behaviouralrepertoireof the species,or resultfrom abnormalor unusualbehaviour,e.g. "garbage bears". Wildlife may transmit diseasesto domestic animalsor humans.Some examplesare salmonella,tularemi, anthrax, and hoof and mouth disease(Borg 1978). The most dangerous diseaseis rabieswhich is very widespreadin Central Europe. It is absent from the BritishIsles,Iceland, Portugal, Greece and Scandinavia(but occurson Svalbard).In West Germany, 1000-5000 casesof rabiesare annuallyobservedamong red fox, and 150-500 in roe deer (DJV 1987). In 1987, 5 million samplescontainingvaccineswere laid out throughout 1/3 of the entire area of West Germany, to irnmunizeanimalssucceptible to infection. Similartacticsare alsousedin Belgium, France,Italy and Austria(CE 1988), and in Finland(Westerling 1989). To stop the northerly spread of rabiesin Denmark, comprehensiveexterminationsof red fox and badger were carried out in southern Denmark (e.g. Strandgaard& Asferg1980). The most serious damage to forestry and agriculture is causedby big game species,such as red deer, roe deer and wild boar (e.g. König 1976, Ueckermann 1981). Not only mammalian predatorscan kill livestockand reindeer,but also golden eagles (Aquila chrysanos) may kill calvesand lambs (e.g. Karlsen1978). Big game animals may causetraffic accidents,which sometimes even lead to human mortality. In West Germany,traffic accidentscausedby wildlife have resultedin damagescalcu31 nina utredning018 7 Fauna protection However, measuresundertakento help certain speciesmay be harmful to other species.Hence, certain measureswhich intend to increaseexploitedgame populations,may be detrimentalto other wildlifespecies,or to the generalproductivity of the habitat. Earlierin this report, many examplesof protectionof certain speciesagainsthunting have been mentioned. In somecases alsohabitat conservationmeasureswere used,aswas already the casewith the last living aurochsin Polandaround 1600 (Szafer1968). 7.1 Threatened However,more modern conservationmeasuresbecamemore populararound 1900, and than to a large extent inspiredby North Americanpolicies.National associations for natureconservationwere founded in Great Britainin 1895, in Francein 1902, in Germany and in the Netherlandsin 1905 (Madsen 1979). species Smit & Wijngaarden(1976, 1981) list36 speciesof mammals asthreatenedin Europe.Fordefinitionsof differentcategories of threat, see Fitter & Fitter(1987). Excludingthe SovietUnion, the following mammalianspeciesare regardedasendangered: Europeanmink (Lutreola lutreola), otter, monk seal (Monachus monachus) (in the Mediterranean) and mouflon (the purebred population on Corsica). In addition to some speciesof whale, the following are characterizedas vulnerable: wolf, wolverine,lynx, pardel lynx, walrus (Odobemus rosmartis) (on Svalbard),common seal, ringed seal, grey seal, SpanW-libex(Capra pyrenaica) and red deer (sub-specieskursicanus on Sardinia).The following are categorized as rare species:brown bear, polar bear, genet (Genetta genetta), wildcat (Felis catus) and muskox (after introductionsin Scandinaviaand Svalbard,seeMyrberget 1987). Most conservationwork during the firstyearswas, however, relatedto sitesof particularbeauty. But protectionof characteristicecosystemsand vulnerablespecieswere alsooften taken into consideration.A famous contribution is a book by Hornaday(1913) on our vanishingwildlife. There are many legal methodsfor protectingwildlife species and their habitats(e.g. Ranerås1985) includingthe following: 1) protect habitat as reservesand national parks,2) protect particularspeciesagainsthunting, 3) minimizethe detrimental effectsof human use of habitat and resources,4) ascertain that the total benefits of certain human activitiesare greater than the costs,and 5) control that the level of output of certain chemicalsare lessthan given limits. Measures (1) and (2) are most commonly used. However, protected areascoveronly small partsof any country, e.g. about 4% in Fennoscandiancountries(Norderhaug & Norderhaug1986). Therefore the management of unprotected areas is also of great importance.Other species-orientedmeasuresthan protection may be of significance(see Temple 1977). Here, measuresdirected at conservationof particularspecieswill be emphasized. Within the partsof Europedescribedin this paper, only one bird speciesis classifiedas endangeredin the IUCN BirdRed Data book (see Parslow& Everet1981, ICPB& IWRP1987), i.e. the Spanishimperialeagle (Aquila adalberta). Three speciesare internationallyregardedas vulnerable:the Dalmatian pelican (Pelicanus crispus), the white-tailed eagle (Haliaëtus albicilla) and the peregrine(Falco peregrinus). Audouin'sgull (Larus audouinii) and roseatetern (Sterna dougallii) are rare. Severalspecieshave been registered as candidatesfor the Red Data book. Among thern are the lesserwhite-fronted goose (Anser erythropus), four speciesof birdsof prey, the little and great bustard(Otis tetrax and 0. tarda) and the corncrake. The list also includesthe probably most threatened bird speciesin Europe,the slender-billedcurlew (Numenius tenuirostris) which breedsin Siberiaand is hunted during migrationsover the Mediterranean. International protection of threatened specieshas in later yearsbeen the responsibilityof IUCN's SurvivalServiceCommission(SSC)which was founded in 1950 and becamea full commisionin 1956 (Fitter & Fitter 1987). A milestonewas the publicationof the two first Red Data books,on threatened mammals and birds, in 1966. A Red Data book is defined as a registerof threatenedwildlife that includesdefinitionsof the degree of the threat (Fitter& Fitter1987). Most countriescompile national listsof threatened species. In Francethe listcontains59 threatened speciesof mammal and 36 birds. Seven mammals and 61 birds are listed in Norway (Christensen& Eldöy 1988). In Finland, 17 mammals and 38 birdsare listed, although many of these in the category of unsufficientlyknown (Miljöministeriet 1986). Figuresfrom differentcountriesare unfortunatelynot directly comparable, because different criteria are used (e.g. järvinen & Miettinen 1988). The ECEhas now started a project for coordinating national listsof threatened speciesin Europe. Lateron, most Europeancountrieshave made their own national Red Data books. Main measuresin fauna protection now involve habitat protection, including wildlife reserves and nationalparks. 32 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. nina utredning018 The mostsignificantthreatsto wildlifespeciestoday are alteration of habitat, biocidesand measuresfor predator control. Ordinary hunting alone hardly representa seriousthreat to any European speciesof wildlife. Illegal collectionsof eggs and young of rare bird speciesis a problem in many areas (e.g. Cramp 1977). suchasthat of wild boar troductionshave been unsuccessful, to Ireland(Lever1985), and of penguinsto northernNorway (Niethammer 1963). Severalsuccessfulre-introductionshave already been mentioned, including the beaver in Scandinavia.Birdsof prey such as the white-tailed eagle in Scotland(Love 1988), the goshawk (Accipiter gentilis) in Great Britain (Marquiss & Newkin 1982) and the griffonvulture(Gyps fulvus) in France, håve also been successfullyre-introduced. Even the raven (Corvus corax) has been re-introduced to Belgium (Lever 1987). Re-introductionof ibex to Czechoslovakiaby using (Read & two exotic subspecieswas, however, unsuccessful Harvey1986). Globally speaking, Europe has a low number of threatened species(Diamond et al. 1987). One explanation for this is that civilizationin Europeis ancient, and many specieswere probablyalreadyexterminatedin the past. In addition, there are few isolatedoceanicislands,and no rainforestswhich on other continentssupportmany threatenedspecies(e.g. Soul 1987). The international conventionspreviouslyitentioned are of major importancefor conservationwork (Grimmett & Jones 1989), while the World Heritage Convention of 1972, and CITESor the WashingtonConventionof 1973 on International Trade in EndangeredSpeciesof Wild Animals (see Lyster 1985) has hardly resultedin significantadvantagesfor European wildlife, althoughthey are of great importanceon other continents,e.g. in Third World countries. 7.2 • Re-stockingis sometimes essentialfor maintaining populations, as is the casewith the pheasantin the northerlyareas of its distribution.Introductionsmay alsobe usedto strengthen threatened populationslikethe peregrineand the eagle owl (Bubo bubo) in Scandinavia(Myrberget 1987). In Central Europe,introductionsare usedin attemptsto savethreatened populationsof woodland grouse (Aschenbrenner1985). Reintroductionshave been necessaryto conservethe famous population of barbary apes (Macaca sylvanus) at Gibralter (Niethammer 1963). IntroductIons In the past, most exotic specieswhich were introducedaccidentally, had escapedfrom fur farms. More recently,interest for farming deer specieshas increased.Evenin a smallcountry like Denmark, there are more than 400 deer farms with more than 2000 animals,mainlyfallow deer (Hansen1988). In many countriesestablishmentof suchfarmsisstrictlycontrolled to protect wild living populations (see also IUCN 1988, Hudsonet al. 1989). Successfulintroductionsof exotic speciesmay conspicuously alter a country'sfauna (e.g. Ebenhard1988, Whelan 1990). Re-introductionsmay build up populationswhere a species has previouslydied out. Introductionsmay be deliberate,or resultfrom animalsescapingfrom captivity.The IUCN (1987) has passeda resolutionconcerning acceptable premisesfor introductions.Regulationsand lawsin many countriesseverely restrictintroductions.The Council of Europe hasfound it necessaryto passa specialrecommendationon introduction of cottontail rabbits (Sylvilagus floridanus) and other nonnative Leoporidae(CE 1985b). 7.3 Game management conservation versus Today hunting is generallyacceptedasa part of conservation providedit exploitsrenewableresources.Biggame huntingis regarded as necessaryin the absenceof effectivepredators. As previouslymentioned, huntersare often engaged in practical wildlife management, much of which hasdirect positive for general cbnservation efforts. consequences Severalexamplesof successfulintroductionsof exotic species have alreadybeen mentioned. Introductionswere particularly common in Great Britain(Linn 1979), and include 3 species of pheasant, red-legged partridge, bobwhite quail (Colinus virginianus), ruddy duck (Oxyura jamaicensis), mandarin duck (Aix galericulata), Egyptiangoose (Alopochus aegyptiacus) and the red-neckedwallaby (Macropus rufogrisens) (Lever 1985, 1987). Speciesintroducedin other countriesare the California quail (Lophonyx californicus) and the mongoose (Herpestes ichneumon). On the other hand, one must admit that game management often only considersshort-term benefitsdesignedto increase a huntingyield. Exoticgame specieswere introducedregardlessof environmentalconsequences.The numberof gunshas been increasingrapidly in later years. Hunting may increase pressureon speciesalreadythreatened by pesticidesor habitat destruction.On the other hand, nationalparks,nature reservesand speciesprotection may reduceexploitationof cer- European game specieslike the mute swan (Cygnus olor) have also been transferredto other Europeancountries.Another example is the introductionof brown haresto Ireland, Swedenand Finland(Niethammer-1963). However, many in33 nina utredning018 8 Wildlife tain viable populations.Thereforethere is alwaysa degree of conflictof interestsbetween game managementand wildlife conservation. research Wildlife managementshouldbe basedon resultsof research. In many countries,centralinstitutionsare responsiblefor applied research,while in othersresponsibilityrestswith universities.One seriousproblem is that resultsof researchoften never reach thoseengaged in practicalwildlife management (Pettersson1987). Wildlife management is in many cases basedon preconceivedideasabout usefulmeasures. In Europethere is an increasingoppositionto hunting. Attitudes againsthunting are related to scientificaswell as emotional arguments.Oppositionappearsto be particularlyconspicuous in Italy, among both landowners and conservationists (Spina 1987). This may be due to prevailing lackof respectfor hunting laws, high densitiesof hunters,no landowners'hunting rights, little active game management, large numbersof small birds in the hunting yields,and lacking hunting statistics.Two-thirds of the population of Italy areopposedto hunting, and 3/4 of the youngergeneration. On the other hand wildlife researchis not alwaysdesignedto solvepracticalproblems.A scientistis generallyevaluatedaccordingto purelyscientificcriteria,and respectfor appliedresearchshouldbe increased. Antipathy concerning hunting is also increasingin parts of Scandinavia,but hunting is far more accepted.In 1980, 18% of the population of Sweden had a positiveattitude toward hunting, while 54% accepted hunting practices (Ekström 1981). Only 10% were directlyopposed.Aversionto hunting wasgreatestin cities,where it was regardedasan obstacleto the pursuit of other outdoor recreationalactivities.Women frequentlycited ethicalreasonsfor opposinghunting. Large-scaleresearchschemeson centralgame speciesstarted already around 1900, such as researchon deer in Germany (see Raesfeldt1898) and on red grouse in Scotland (Committee of Inquiry on Grouse Disease 1911). Around the World War II, the influencefrom North American scientific publicationswas marked, e.g. the work done by Errington (1946). In the 1950's important researchprojectswere made or started up in many Europeancountries,suchasstudieson roe deer in Denmark(Andersen1953) and on tetraonid birds in Fennoscandiaand Great Britain (Hagen 1952, Siivonen 1957, Jenkinset al. 1963). Studieson general ecology and ethology (e.g. Tinbergen 1951, Lack 1954) inspiredapplied research. The Committee of Ministersof the Council of Europe proposeda hunter'scode of conduct (CE 1985) as a meansfor reducingoppositionto hunting. Thiscontainedguidelinesfor hunter behaviour,and responsibilityfor natural heritage affecting humanity in general. The Council of Europe (CE 1987a) has more recently found it necessaryto emphasize the value of hunting and its role in preservationof wildlife habitat There is no formalizedgeneral cooperationbetween wildlife researchbodiesin the differentEuropeancountries.The main purposeof the IUGB(The InternationalUnion of Game Biologists)is to arrangebiennialinternationalgame researchcongresses,which most often are held in Europe.Formalizedregional researchcooperation schemes such as the Nordic Councilfor Wildlife Researchdo exist.The IWRBhasits headquartersat Slimbridge,Englandand coordinatesregistration and monitoring schemeson waterfowl and wetlands. Other international organizations like the ICBP involve scientists from many Europeancountriesin their work. Many of the congressesand symposiaarrangedwithin Europesuchasthe grouse symposiaarranged by the World PheasantAssociation, are of great significance.International ornithological and theriologicalcongressesare alsoof great value for European scientists. In the rapidlychangingworld of today, wildlife management requires more than ever information obtained through research.Due to more sophisticatedresearchmethodsbeing in use, many more questionsmay be asked now than before.

Progressin wildlife ecology must primarily be made through long term programscombining theoretical, experimentaland practical research. remarks The managementschemesfor wildlife vary from countryto country.This is alsothe casefor management of game speciesand their habitats,and for game harvestingsystems.The most effectiveand productivesystemsare found in countries where the landownerscontrol hunting rights,or where officialsor hunting clubsstrongly regulatethe harvest(see also Bubenik1989). Overexploitationof game stocksis often the casein other partsof Europe. This short review indicatesthat cooperation between different countriesin wildlife management should be improved.I do not thereby imply that all countriesshould have similar hunting seasonsetc., but common managementaimsof animal populationswhich crossnational boundariesare essential. Wildlife managementschemesseem to be built more on tradition than political systems;e.g. the revier systemused in Eastand West Germany have many aspectsin common. On the other hand, the revolutionin Portugalin 1974 hasobviouslycontributedto deterioration in controlsof hunting activities. Many of the mesauresused in wildlife management should be scientificallyevaluated. However, constructivecriticismis largelybeyondthe scopeof this report. In recent years, global and national challengesconcerning the future of wildlife populationshasfortunatelyled to growing awarenessof the need for good basic knowledge, increased international cooperation and generally accepted short- and long-term conservationstrategies.Huntersare increasinglyconsciousof the fact that game populationscannot be managedfor the sakeof hunting alone. Thesetrends combined give hope for the future. However, many of the tasksareformidable,needinggreat effortsto be solvedon local, nationaland internationallevels. 35 nina utredning018 10 Summary migratorybirdsin Europeis highlydependent on international agreements,in particularthe Berne convention of 1979, the EECBirdDirectiveof 1979 and the RamsarConventionof 1971. Thisreport presentsa brief reviewof some practicesand principlesof Europeanwildlife management.The SovietUnion is not discussed.Emphasisis placedon managementof hunted species(game), but conservationmeasuresinvolvingother fauna are also mentioned. The review includesall speciesof birdsand mammalswith the exceptionof insectivores,bats, smallrodentsand whales. Game management practicesused for non-migratory small game speciesare largelyleft up to landowners.In somecountries in central and eastern Europe, certain management measuresare obligatory. Among practicesoften employed are predator control, introduction of game, and feeding. Measuresfor conservingor increasingthe productioncapacity of naturalhabitat or diminishingthe negativeeffectsof human activities,are increasinglyimportant. Applied methodsfor game management and hunting in Europe are clearly influenced by practicescommon in other partsof the world. Game management in Europetoday, has historicalrootsin.classicalGreekand Romancivilization. The most productivehuntable populationsare usuallyfound in countrieswhere hunting rightsare exercisedby landowners,or where authoritiesor hunterorganizationsstrictlyregulate hunting yields. In countrieswhere hunting priviledges are open for everyone, many game speciesare obviously over-exploited. In such countries,opposition to hunting is considerableand increasing. The time between 800 and 1800 A.D. may be characterized as a period where the exclusivehunting rights of the aristocracyexpanded,and little was done to protect game species. Around 1800, the aristocracywas deprived of hunting priviledges,and hunting pressurewas regulatedby game authorities.At the sametime, active methodsfor conservingand increasing the production of game species were gradually introduced. Human activitiesincreasinglylead to problemsfor the production of many game species,and threaten the existenceof some. These activitiesinclude agriculture,forestry, tourism and industry. Pollution, such as acid precipitation and exhaust from •automobiles,have negative consequencesfor game populationsand their natural habitats. 1nsome cases conflictsarise between game management intended to in-. creasehuntingyieldsand the interestsof conservation. Game management is practicedat many different levelsby: central and local authorities,landowners,huntersand other personsinterested in nature. To a varying extent, hunting rights are associatedwith landownership rights. Excluding the SovietUnion,there are about 8 million huntersin Europe, or approximately1.6 huntersper km2. Membershipin hunters associationsis either voluntary or obligatory. 1n most countries,an obligatoryhunter'sexaminationhasbeen introduced. The examination involvestheoretical knowledge as well asthe practicaluseof firearms. Wildlife management increasinglyemphasizes the importanceof research.However,at the presenttime there is no internationalorganizationto coordinatewildlife researchin lurope. Much modern game management is a continuationof age old traditionsand biasedattitudes. Evaluationof which game speciesis most important varies throughout Europe.Economicallyspeaking,different species of big game (larger herbivorousmammals) are of greatbst significance.The initial value of game felled in Europeis estimated at 700 millionU.S.dollars. Although the threat to many game speciesand their natural habitatsincreases,the desireto solve problemshas also becorne stronger. Solutionsare dependent upon considerable localand nationaleffort and internationalcooperation. In certain countries (Denmark, Great Britain and Ireland), each landowner may independently control the number of individualsof each big game speciesto be killedon their own grounds.In other countries,quotasare establishedby authorities or huntersorganizations.1n most countries,huntinglicensesare issuedwithin defined hunting territories,which may be establishedby the government or voluntary agreementswith landowners. In contrastwith common practicein North America,there is no system in Europe to control the hunting pressureand yield of migratory birds along flyways.The managementof 36 nina utredning018 © Norwegian institute for nature research (NINA) 2010 http://www.nina.no Please contact NINA, NO-7485 TRONDHEIM, NORWAY for reproduction of tables, figures and other illustrations in this report. 11 Sammendrag satt i verk. 1 en del land i Sentral-Europaog Øst-Europaer dog enkeltetiltakobligatoriske.Blanttiltak somofte benyttes, er bekjempelseav rovvilt, utsettingerav vilt og utleggingav fôr.

Hovedvektener lagt på forvaltningen av jaktbare arter, men det er inkludert noen tiltak for å bevareden høyerefauna. Oversiktenomfatter alle arter av fugler og alle pattedyr unntatt insektetere, flaggermus,smågnagereog hvaler. De mest produktivejaktbarebestanderfinner man som regel i de land hvor grunneiernedisponererjaktretten, eller hvor strengtregulererjaktmyndigheterellerjeger-organsisasjoner uttaket.I en del land hvorjaktrettener fri, er åpenbartmange viltarter overbeskattet.I disselandene er gjerne motstanden mot jakt storog økende.

Samtidigble mer aktive metoder til å bevareog øke viltproduksjoneni økendegrad tatt i bruk. I økendegrad blir det i viltstelletlagt vekt på forskningensresultater. Noen overnasjonalstyring eller planleggingav viltforskningenfinnes imidlertid ikke i Europa.Mye av viltstellet drivesennå med basisi tradisjonerog forutintatteoppfatninger. Viltstelletdrivespå mange plan:av sentraleog lokalemyndigheter, grunneiere,jegere og andre naturinteresserte.I varierende grad er jaktretten knyttet til grunneier-retten.Utenom Sovjet-Unionener det omkring 8 millioner jegere i Europa, dvs. 1,6 jegere pr. km2 landareal.Medlemskapi jegerforeninger er i varierendegrad frivillig eller obligatorisk.I de fleste land er det nå innført en obligatoriskjeger-eksamen,som både omfatter teoretiskefag og skyteferdighet. Selvom truslenemot mange viltarterog deresmiljø harvært stadigøkende,synesogsåviljen til å løsemange problemerå væreøkende. Men dette vil kreveen stor innsats,både lokalt, nasjonaltog internasjonalt.

En forkortet norskversjon er gitt i en artikkelseriei "Naturen"i 1989-90. I noen få land (Danmark, Storbritanniaog Irland) kan grunneierenefritt bestemme hvor mange av de ulike storviltartene de vil felle på egen grunn. I andre land er jaktuttaketav storvilt i større eller mindre grad regulert av myndigheteneeller av jeger-organisasjoner.I de fleste land er fellingslisensene knyttet til definerte jaktområder, som kan være fastlagt av myndigheteneellerfrivilligav grunneierene. I motsetningtil hva som er tilfellei Nord-Amerika,finnesdet i Europaikke noe systemhvor jaktuttaket av trekkendefugler fastleggeslangs trekkruter (flyways).I forvaltningenav disse artene betyr internasjonaleavtaler mye.
