They occupy >260,000 km2in 5 Andeancountries, and if their densities are comparableto those of North Americanblack bears (Ursus americanus),the total populationmay be >20,000. Unbroken tractsof the Andes stretching more than 200 km and extending over 3000 m of elevation exist for this species in Peri and Bolivia, where over2/3 of the bear's rangeoccurs. Approximately18.5%of the rangeis containedwithin 58 protectedareas. Althoughthe species probablyis not on the brink of extinction in the wild, serious threats exist. Hunting may now be as importanta factor in bear populationdecline as habitat destruction. Lack of land ownershipand credit combined with increasedroad access has precipitatedthe spreadof informaleconomic activities (e.g., shifting agriculture,grazing, mining, narcoticproductionand trafficking,timberharvest, and huntingfor animalparts)in bear strongholds. Drug traffickershave infiltrated 16 parks occupied by bears; this number is triple what it was 15 years ago. Internationaltrade in bear gall bladdershas been confirmed in Ecuador. The future existence of wild Andean bears depends on linking conservationwith benefits that have meaningto local communities. The potentialroles of government,communities,and privateorganizationsin managingnaturalresourcesfor both bears and humanprosperityare discussed. Ursus 10:87-100 Key words: Andean bear, Andes, conservation,policy, South America, status, threats, Tremarctosornatus. Andeanbearsarepartof a diverseSouthAmericanlandscape that struggles with the same problems sharedby developing countriesthroughoutthe world. The disparity of resourceownershipbetween rich and poor, which is larger than on other continents (LaFeber 1986), perpetuatesa situationwhere landless farmershave increasing access to bear habitatthat they develop to support themselves. Resourcepolicies can be imposedby central authorities(top-down approach)or decided at the community level (bottom-up). We argue the need for both approachesto addressthreatsfaced by Andeanbears. Most rural communities do not own land; thus, they lack the authorityand will to preventthe destructionof forests. Agencies withinAndeangovernmentsface similarproblems. Ministriesthatoversee extractivelanduses and colonization are typically better funded than agencies dedicatedto preservingnaturalresources. The national parks these agencies establishedwith the help of privateorganizationsarebeing invadedby industriesand colonists, andthe agencies have little meansto preventit. However, governments,communities,and privateorganizationsare redefiningtheirroles in ways thatmay prevent the destructionof Andean watersheds. We summarizethe statusand majorthreatsto Andean bearpopulationsand theirhabitatand place these threats in a broadersocial, economic, and political context. We discuss what can and should be done by social institu- tions and governmentagencies to preserveresourcesfor both people and Andeanbears.

STATUSOF ANDEANBEAR POPULATIONS Andean bears occupy about 260,000 km2 of forested habitatin Venezuela, Colombia,Ecuador,Peru, and Bolivia (Table 1). This estimate was obtainedby drawing boundarieson topographicmapsaroundareaswherefield expeditionsconfirmedthepresenceof bears(Peyton1980, Brown and Rumiz 1988, Suarez 1989). Roadless areas that were not surveyed for bears were included in these boundariesif they were adjacentto surveyed areas and containedhabitattypes thatbearsoccupied elsewhere on the same Andeanrange. Boundariesof unsurveyedareas were drawn from configurationsof these habitat types depictedon governmentvegetationmaps. We estimated the size of these areasby superimposinga grid on them (1 cell = 100 km2)andthen summingthe partsof the grid within theirboundaries.

ANDEANBEAR STATUSANDMANAGEMENT POLICIES* Peyton et al. like those of NorthAmericanblack bears,most of which are hunted (low = 7/100 km2, median = 25/100 km2, Garshelis 1994), the total world population would be 18,000-65,000. Because these estimates are for adult bears, we believe there are >20,000 total bears in the Andes. STATUSOF PROTECTEDAREAS Approximately 18.5% of the Andean bear's range (48,390 km2)is legally protected. Most of the protected range is in Bolivia (52%), followed by Ecuadorand Colombia (17% each), Peru (12%), and Venezuela (2%). These protectedareasinclude58 nationalparks,reserves, or sanctuaries;all but 3 were establishedsince 1968, and 12 were establishedin the 1990s (Table 1). Eight areas consisting of either a single parkor interconnectedones have >1,900 km2of bear-occupiedhabitat(Fig. 1, areas 4-6 and 8-12). This was the mediansize of 41 parksthat were believed to supporta stable or increasingpopulation of Andean bears in 1988 (Peyton 1988), and thus representsa possible targetsize for populationviability. Four more areas could have >1,900 km2 of bear-occupied habitatif bearsexpandtheirrangewithinthem (Fig. 1, areas 1-3 and7). Humanactivities(e.g., grazing,shifting agriculture,and illegal mining) inhibit bears from occupying habitatthatcould supportthem in these areas. Venezuela, Colombia, Ecuador,and Bolivia have enlarged and connected parks during the last 15 years to protect bears and increase the biodiversity within the parks. INPARQUES,the governmentagency that manages Venezuela's parksand naturalresources,is encouraging range expansion by creating new parks that connectedmost of its conservationunits in the Cordillera Merida (Fig. 1, area 1; see Yerena and Torres 1994, Yerena 1998). The result has been the creation of a complex of 5 national parks (e.g., Sierra Nevada, Batallon y la Negra, Chorroel Indio, Potosi, and Tapo Caparo) that includes 5,030 km2 of potential habitat for Andean bears. In 1989 the ColombiangovernmentaddedTiniguaand Los Picachos National Parksto the NationalParkSierra de la Macarenafor a combined area of 12,710 km2(Fig. 1, area4). In 1993 and 1994 the Ecuadoriangovernment added the AntisanaEcological Reserve and the Sumaco Napo-GalerasNationalParkto the Cayambe-CocaEcological Reserve in northernEcuador (combined area = 7,280 km2,Fig. 1, area 5). The World Heritage Site of Sangay in centralEcuadorwas almost doubledin size in 1992 from 2,719 to 5,177 km2to protectthe PauteRiver drainage,an importantwatershedfor urbanresidents in 89 the mid-Andeanrange (Fig. 1, area6). These recentEcuadorian park developments also protect woolly tapir (Tapiruspinchaque), an endangeredanimal that lives in approximately20% of the Andeanbear's range(Downer 1996). Approximately10,000 km2of bear-occupiedhabitatin northernBolivia was legally protectedwhen Alto Madidi National Park(Fig. 1, area 10) was establishedin 1995. The park connects the national parks of Ulla-Ulla and Pilon-Lajas (Ribera 1996). Amboro National Park (establishedin 1973) andits adjacentmanagementareacontain over 4,000 km2of occupied bear habitat. When an adjacent area was declared CarrascoNational Park in 1988, 12,610 km2of Andean bear habitathad protected statusin centralBolivia (Eulert 1995; Fig. 1, area 12). The creationof parkson countrybordershas been an effective tool in defusing political conflict and promoting cooperative resource management (McNeil 1990). There are 3 Colombianparksthat are paired with parks across borders: El Tama and Tama (Venezuela), CatatumboBari and Perija(Venezuela), and Los Katios andDarien(Panama).Othercorridorscould be protected that would link Ecuador'sparkswith those of its neighbors. Thecorridorenvisionedfor EcuadorandPeruwould join PodocarpusNational Parkto Tabaconas-Namballe National Sanctuaryin Peru and extend 200 km to the northeastto include the Cordilleradel Condor. Another corridorcould link the Awa ForestReserve andEl Angel Ecological Reserve in Ecuadorwith the La PlanadaNatureReserve in Colombia. Measuressuch as these maintain large areasof cloud forestfor Andeanbearsand give the species a more hopeful future. THREATSTO ANDEANBEARSAND THEIRHABITAT Access to Bear Habitatand Land Reform The dominantthreatto Andean bear populationsis a growing population of landless peasants that have increased road access to cloud forests (Suarez and Garcia 1986). Currently,10%of the humanpopulationin these 5 Andeannationslive in the cloud forest and their numbers are increasing at an annual rate of 1.5% (Young 1992). Roadsenablemigrantfarmersto establishillegal settlements in bear habitatand are the axes from which agriculture expands and fragments bear populations. The primaryaxes of fragmentationare the roads in the interAndean valleys. Humansettlementsand degradedland here prevent bears from moving between the 3 Andean 90 Ursus 10:1998 720 Fig. 1. Range of the Andean bear in South America's protected (black shaded) and unprotected (gray shaded) parts of the Andes, 1995. Numbers denote parks or reserves that contain >1,900 km2 of habitat occupied by or available for Andean bears. ANDEANBEARSTATUS ANDMANAGEMENT POLICIES* Peyton et al. ranges, especially in Colombia and Peri where the 3 ranges are most distinct. Andean bears have been displacedby people in almost all valleys <1800 m elevation with the exception of roadless areason the easternslope of the OrientalAndes. The second axes of fragmentationis along roads that cross the Andes. Typically, these roads pass through mountainsaddles;scatsandfeedingsign suggestthatbears use these saddles to cross sides of a mountain range (Peyton,unpubl.data). As humansettlementsproliferate along these roads,bear populationsbecome increasingly isolatedin a processthatcan occurrapidly. In the Yungas regionof Bolivia, Liberman(1991) foundeffects on large mammalssuch as Andeanbearsthatextended2 km from roads duringthe initial stages of road construction. The conditions that forced farmersto move into bear habitatwere lack of land ownership and failure of land reform measures to redistributeland to them (Peyton 1994). By the 1950s, 2-5% of the humanpopulationin the Andean nations owned 60-80% of the arable land (Eckstein 1983, Gradwohland Greenberg 1988). This inequitable land distributionand the increased peasant population forced families to abandonfields that were too small to supportthem. In Peru23%of the population (2 million people) were migrantin 1962. Most of these farmerswent to urbancenters seeking educationand entrance to the industrialclass of society. These emigrations combinedwith high urbanbirthrates (e.g., 4.5-5% annuallyin the 1960s; LaFeber 1986) explain why 5191%(Bolivia-Venezuela)of the humanpopulationis now urbanin the 5 countrieswith bears (WorldResour. Inst. 1992). South American countrieshave the most urban populationsof all developingpartsof the world(Gonzalez 1991). This places tremendouspressureon governments to provide employment and on bear habitatto provide resources. Peasantsleft overpopulatedurbancenterson theirown once accessto morepromisingemploymentwas provided. Governmentsthreatenedwith social unrestfrom unemployed urbanpeasantsbuilt roads over the Andes to the Amazon basin. Colonizationprogramswere initiatedat the ministerial level to encourage migration over the Andes for otherreasons. Oligarchiescould retainpower andnot be forcedto distributetheirland. The statecould populateits remoteregions to defend bordersand to provide labor to producefood and exportproducts(e.g., oil and timber). The latterwas consideredcollateralby the developedcountriesfor theirbilateralaidthathelpedbuild the roads. During20 yearsof roadbuildingin Peru(196080), huntersandfarmersestimatedthatPeru'sbearpopulation declined by a third (Peyton 1981). The Bolivian 91 road system increasedby 70% following the 1952 AgriculturalRevolution. In Colombia73,000 km2have been clearedin government-sponsoredcolonizationprograms, an area equivalentto 28% of the Andean bear's present range. Deforestation and Informal Agriculture An estimate of the rate of deforestationin the entire Andean mountainrange does not exist, but it is severe. In Ecuadorthe forests between the Andean ranges is almost gone, and only 4% remainson the westernAndean slope (DodsonandGentry1991). Hendersonet al. (1991) estimated that <10% of the Andean forest remains in Colombia. Most deforestationof Andeanbearhabitatis theresultof slashandbum agriculture.Typically,a farmer clears 1-3 ha of cloud forest, burnsit in the dry season, and plants corn, beans, and squash. When soil nutrients areexhaustedafter3-4 years,the farmercuts a new field, usuallyup-slopefromthe old one, andplantsthe old field in rhizomatousgrass for cattle. In this fashion the forest edge recedes approximately100 m every crop rotation. Most of the cloud forest habitatfor Andeanbears below 1800 m elevation has been replacedby agriculture. Cattle grazingalso damageshabitatfor Andeanbears. Peasantsuse cattle as a hedge againstlean times caused by events such as crop failures;cattle can be tradedfor other goods. One of the ways the aristocracymaintains tight controlof the peasantcommunitieson their land is by employing cattle rustlers to steal peasant livestock. Practicessuch as these encouragepeasantsto thrusttheir cattle deeper into bear habitatwhere they are harderto find. Favored grazing sites are on grasslands above the forest and in the mosaic of abandoned cornfields at the lower forest edge. Cattle knock over trees and trample soil. After a decade cattle can reduce an intact cloud forest to bare pasture with deep eroded gullies. Unfortunately the best areas for crops and grazing coincide with the best food-producing habitat for Andean bears. These are the grasslands above cloud forests (generally above 3,000 m, depending on latitude) that provide bears with berries (Ericaceae spp.), terrestrial bromeliads (Puya spp.), and frailejon (Espeletia spp.), and the cloud forests below 2500 m where Andean bears eat tree fruit, palm leaf petioles, and epiphytic bromeliads (Tate 1931, Peyton 1980, Goldstein 1988, Suarez 1989). Andean bear populations are increasingly restricted to the area between these agriculturalbands; this area is characterized by steep slopes (50?-70?) covered with bamboo (Chusquea spp.), which Andean bears do not eat. 92 Ursus 10:1998 Hunting Illegal huntingappearsto be more widespreadthan it was 15 years ago, partly because increased fragmentation of bear habitatand its conversion to humanhabitation has exposed more bears to hunters. Hunting is consideredto be the greatestproblemfor bears in Venezuela (Yerena 1998). Venezuela has the most urban populationof all SouthAmericannations(WorldResour. Inst. 1992) and has lost a greaterpercentageof its cloud foreststhanany of the other4 Andeannationswith bears. Farmerswho for centuries revered the Andean bear (Randall 1982) increasinglyregardthe animal as a pest and threat to their livelihood. They enlist the help of hunters (e.g, military, civil police, the aristocracy,and foreign sporthunters)who find the bear easy to shoot in the cornfields. Formerly,huntershad limited success in finding Andean bears in the cloud forest, even with the use of dogs to tree them (Peyton 1980). Now, bears are attractedto cornfields at the forest edge. Farmersfrom the eastern slope of the OrientalAndes in northernEcuador,Perui,and southernBolivia say that annually 1-3 bearsarekilled/valleyin theircornfields(Peyton,unpubl. data). Although all 5 Andean countrieshave laws that prohibithuntingAndeanbears,the laws are not enforced due to lack of trainedpersonneland funds to operatean enforcement program (Marconi and Donoso 1992, Young 1992), reluctanceof governmentsto place armed forestrypolice in areascontrolledby terroristsand drug lords, suspicion that armedmembersof the forestrypolice might become terrorists(Peru), and illegal hunting done by those who are chargedto prevent it. TradeBarriers, CommercialAgriculture, and Drugs Commercialagriculture,worldtradeissues (e.g., sanctions and price competition),and subsidies on domestic food productionnow adverselyaffect an estimated20% of the Andean bear's range, and their impacts are increasing. The following example from Colombia illustrates how government policies designed to improve agriculturaloutput tend to fail and increase the illicit economy. In 1971 a consortiumof internationalagriculturalresearch centers developed a new rice variety in Colombia thatcould increaseyield by as much as 40% (Hansen 1986). However, governmentpolicies did not provide owners of small farms (1-5 ha) access to credit, technology, andequipmentto take advantageof the new rice. Colombia's governmentfavored the industrialagriculturalistby extending them low interest loans and training. In the late 1960s and early 1970s, 88% of the financialcreditin the agriculturalsectorwent to the 0.7% of farmsthat were >500 ha (Hansen 1986). The interest rates on loans to small farmswere higher. Additionally, farmers with small land holdings could not obtain the fertilizers and pesticides that the new rice variety required. Consequentlymany farmerswith small plots of land left their fields, which were acquiredby ranchers and farmers with large land holdings (Hansen 1986). Migrantsenteredthe cloud forestillegally. During 195570, the numberof rice farms diminishedfrom 97,000 to 39,000. In the upland sector nearestthe nationalparks with the most bear habitatin Colombia (e.g., Chingaza, Sumapaz,Tinigue, Los Picachos, and La Macarena),the numberof small (<5 ha) to medium-sizedfarms (5-50 ha) declined by 55% and 59% respectively during this period (Scobie and Posada 1977). The consolidationof rice holdings in the Meta region was representativeof the patternof colonization seen throughoutCentraland South America: pioneers arrived and cleared the land that was absorbedinto large ranches (latifundia),while small farms (minifundia)proliferatedon unstablehighland soils. Many displaced farmersnow grow narcotics near or within national parks with Andean bears. Coca (Erythroxylum coca) and heroin poppy (Papaver somniferum)productionis 2-5 times more lucrativeto these farmersthan subsistence crops (Lee 1989). Consequently more land is being converted to agriculture than would be converted for subsistence use. An estimated 425-510 km2 of forest is cleared each year in Colombiafor the productionof heroin(CavelierandEtter 1995). In 1987 an estimated 7,000 km2 of coca fields occupied the Chapareregion of Cochabamba(Bolivia) wherethereonce were bears. The 2 oldest nationalparks in Peruwith bears,CutervoandTingo Maria(established in 1961 and 1965, respectively)have been destroyedby the expansion of coca production from the Huallaga Valley where half the world's supply of cocaine originates (Garcia 1991). Coca field eradicationfrom the HuallagaValley has precipitatedthe spreadof coca productionto bearhabitatin the ProtectedForestof MatiasSan Carlos and the Cordillerade Sira, (A. Brack-Egg, Ecodesc, Oxapampa,Peru,pers. commun., 1994). Presently 16 parks, most of them in Colombia, have been infiltratedby narcotictraffickers.This representsa threefold increase since 1970. Finally, tradepolicies of foreign governmentshave increased the presence of social unrestand drugs in areas occupiedby bears (Peyton 1994). After Colombiancoffee growersmoved farmersoff theirlandin the Santander Provincesduringthe early 1900s,foreignnationsimposed ANDEANBEAR STATUSANDMANAGEMENT POLICIES tradebarriersand stiff tariffsthat still preventColombia from exportingprocessed coffee. The industrialcoffee growerswho could not penetrateworld marketschanged their productionto drugs. They and their descendants control the drug trade in places like Medellin and Call. The dangerof the drugtradehas preventedfield research and meetings aboutbear conservationfrom occurringin most of the centralandeasternAndeanrangesof Colombia. For the same reasons little is known aboutbears in the CordilleraPerija(Venezuela-Colombia),several areas in Peru (e.g., the coastal Andes north of Chota, the upperApurimacRiver Valley in the CentralAndes, and the Province of La Convenci6n in the southernOriental Andes), and the northernhalf of the Andean bear range in Bolivia. Soil Erosionand Mining The combined effects of land strippedfor crops and overgrazingon steep Andeanslopes erodedsoil. Most of the top soil in cloud forests in the easternAndes is lost immediatelyafterthe forest is cleared (Liberman1991). The total effect of many such small clearings is enormous. For example the sediment load of the Beni River in Bolivia indicated a mechanical erosion of 3,000 tons/km2/year, or 27 times the rate of topsoil erosion in the Amazon Basin (Goodlandand Irwin 1975). The Cauca watershedlost 4,000 tons of topsoil/km2duringa 10-monthperiod,mostly due to farmingon 1-3-ha plots on erosion-pronebear habitat(Hansen 1986). In 1983 the culminationof a decade of deforestationin the highlandsabove AmboroNationalParkresultedin floods that destroyed2/3 of the arableland thatsustainedthe inhabitantsof SantaCruz, Bolivia (Clarke 1983). Increased sediment loads in rivers from erosion has encouragedminersto enterbearhabitatin pursuitof gold (Cifuenteset al. 1989). Minerspenetratefartherinto bear strongholdsthan subsistencefarmers. Their land clearing threatensforests of many parksin the Andes including Perijain Venezuela, most of the parksin the Central Andes in Colombia,Podocarpusin Ecuador,YanachagaChemillenandManuiin Peru,andall the parkswith bears in Bolivia. Tradein BearPartsand LegalProtection Illegal trade in Andean bear gall bladdersby Korean businessmen was confirmed in Cayambe-Coca and Cotacachi-Cayapas (Ecuador; M. Castillo, Fundacion Natura,Quito, pers. commun., 1993). Domestic tradein bear parts has a long history in the Andes (Baumann 1963), but evidence of demand from Asian marketsis recent. Farmers were offered $115/bear gall bladder, Peyton et al. 93 which is many times the monthly wage. The spreadof the narcoticindustrymentionedearlierand its associated violence could provide an impenetrableprotectivecover for full-scale traffickingin Andeanbears and theirparts. Forestrylaws in each of the 5 Andeannationsprohibit the hunting of Andean bears and trade of their parts. During 1992-93, Peruenactedlaws thatallowed the governmentto collect a fee for the transferof endangered wildlife bredin captivity(Andeanbearsincluded)to other captive breedingcenters, creatinga loophole in the prohibition.Transferof Andeanbearsunderthese provisions cost $1,000 (D. AguilarandM. Leo, Asociaci6n Peruana parala Conservacionde la Naturaleza,Lima, Peni, pers. commun., 1993). The laws do not provide for adequate backgroundchecks on either the source of the wildlife (captive bred or wild caught), the integrity of the recipient'sclaim as a captivebreeder,or the fate of bears. The laws thus provide a legal cover for the sale of bears for parts. Similarlaws of 1990 now compromiseAndean bears in Bolivia. CONSERVATION POLICY What should be done to maintainAndeanbears in the wild? We present a threefold message. First, design projects that address the problems of lack of resource ownership,unemployment,and lack of political empowerment. Second, ensure that projectsare commensurate with their location and the capacity of the people who undertakethem. Third, intend for those who are most adverselyaffectedby conservationactionto benefit from projects. Implementingprojects is not so much about achieving biological targets,but a social activity. With that in mind, we will examine the role governments, communities,and privatenon-governmentorganizations play and how to improvethem. Roleof Government Strengthsand weaknesses.-The government'sresponsibility is to ensurethat resourceuse at local levels does not compromisethe nationalinterest. The main attraction of administeringprojectsfrom the top-down is efficiency. Directivescan takeplace overnightandbuy time for bottom-up(locally initiated)measuresto have an effect. Of the 5 countrieswith Andeanbears, Venezuelan land managershave been the most successful at employing a top-down approachto protectingwatershedsand Andean bears. With the use of state-of-the-arttechnology (e.g., satellite imagery, geographicinformationsystem mapping, and computer models that included biological concepts of population viability), 94 Ursus 10:1998 INPARQUES technicians were able to estimate how much forest cover they had in Venezuela and how many Andean bears each forest fragment contained (Yerena and Torres 1994). They determinedthat forests were vulnerableto fragmentationand too small to maintain viable bear populationsif surroundedby human settlements. Their analyses prompted officials to triple Venezuela's national park system, now at 15% of the nationalland area (Colombia has 17%and Ecuadorhas >17%of its landareadesignatedas parks). Whenthe new park of Tapo Caparo has its boundariesfinalized and GuaracamalNationalParkis connectedto otherparksin the CordilleraMerida (e.g., Sierra Nevada, La Culata, GuirigayandParamosdel Batallony la Negra,andChorro El Indio)thejoint parkareawill be approximately10,230 km2(Yerenaand Torres1994). Peru'sbearswould benefitfrom Venezuela's approach by creatingprotectedbridgesbetweenconservationunits. AlthoughPeri has >30% of the totalrangeof the Andean bearin SouthAmerica,only 7% of thatrangeis included withinparkboundaries.In contrastBolivia has 3.6 times as much of this bear range underprotectedstatus. Only 5% of the montaneforest above 1,500 m on the eastern slope of the CordilleraOrientalis included within the boundariesof Perui's3 largest parks with bears (Young 1992), and these parksare separatedfrom each otherby >250 km of unprotectedforest. Six potentialpark candidatesexist in PeruandBolivia where2/3 of the Andean bear's range is found. These corridorshave roadless cloud forest extending for >3,000 m of elevation; these areas, stretchingfor >200 km along the OrientalAndes (facing Brazil), have habitatand elevational conditions that are likely adequateto sustain bears (Peyton 1988). The main weakness of top-downpolicies is the inability of governments to enforce them locally (Bodmer 1994). Top-down implementationis capital intensive and relies on stronginstitutions. AlthoughVenezuela is currentlyundergoinga bankingcrisis, its financial ability to implement top-down approachesto conservation is betterthan that of the other 4 Andean countrieswith bears. A consolidationand decentralizationof resource managementagencies occurredin Peri in the late 1980s and is now occurring in Colombia (since December 1993), severely straining these countries' abilities to implementpolicies. For example, there is only 1 park guard/5,700km2of Andeanbear habitatin Peru (Young 1992), and no vehicles for transportation. With few guards,forestrylaws that protectbears and their habitat tend to be ignored. The situation is similar in Bolivia where only 3 of 36 parks had guardsin 1991 (Marconi and Donoso 1992). Solutions.-Lack of people and capitalresourceshave promptedAndean nations to initiate management-sharing programs,which have benefited both wildlife and indigenouspeople. Collectively, these programsinvolve the decentralization of authority. One of these is privatization,where governmentsrelinquishthe authority to manage naturalresourcesto privategroups. This approachhas been developed to the greatest extent in Colombia, but is increasingly popular throughoutthe Andes. Power-sharingmechanisms exist in Colombia to manageparks and unprotectedforests. For example, regional corporationsand utility companies manage approximately25,000 km2of bear habitatoutside national parks. They are well-funded and capable of protecting habitatfrom development. Another example of decentralizationis the creationof park buffer zones that supportindigenousgroups. Extractiveor biospherereserves that also preserveindigenouscultureexist for many ethnic groupswho sharelandwith bears:Paez, Inga,Ingano, Sibundoy,andKamsa,in Colombia;the Awa andCofane on the border of Colombia and Ecuador, Quechua of Ecuadorto Bolivia, the Amuesha in Peru, and Aymara in Bolivia. More of these kinds of programswill exist in the future as the budgets of resource management agencies get tighter. A conditionfor verticalcontrolof policies is their coordinationhorizontallyacrossministriesanddepartments. Policy contradictionsat the ministeriallevel harmcompliance with policies at lower levels. For example Ecuador's concession of 6,000 km2 for petroleum explorationwithin days of declaringpart of the same area a nationalpark (Sumaco Napo-Galeras)reinforceddistrust of governmentpolicies in the region's communities (Wray and Alvarado 1996). Finally, to provide communities with incentives to move toward sustainable resource use, governments must ensure that local people achieve legal ownership of land and have a principle role in decisionmaking (Hill and Press 1994). Lack of enforcement and the vague terms of ownership that characterize much of the bear habitat in the Andes have left communities with little authority to prevent its destruction (Brown and Wyckoff-Baird 1992). In some cases governments encourage the destruction of forests. Government recognition of land ownership in communities adjacent to 2 Ecuadorean parks with bears (Sumaco Napo-Galeras National Park and CayambeCoca Ecological Reserve) was conditional on the inhabitants converting 50-60% of the forest into cattle pasture, an inefficient way to use land (Wray and Alvarado 1996). ANDEANBEAR STATUSANDMANAGEMENT POLICIES* Roleof Communities Strengths and weaknesses.-Communities provide 3 things most projectsrequire:knowledge, labor, and administrativecapabilitiesbeyond the capacity of outsiders. Local people have more experience with bears and their habitatthan most project planners,particularlyin remote tropicalareas where little is known about bears. Plannersareoftenignorantof the ways communitiesmake decisions and allocate resources,yet such knowledge is essential for projectsuccess. For example contributions of labor in returnfor state taxes and tangible goods has existed since pre-Colombiantimes in the Andes and is knownby a varietyof names (mita,minga). Use of mitas could greatlyimprovethe implementationof projectsthat requirelocal labor. To capturelocal labor,plannersshould base project tasks on currentskill levels (Peyton 1994) and not let dependence on outside specialists undercut local administrativeinstitutions(Lewis andCarter1993). Many communities do not have institutionsthat can simultaneouslyprovidelocal needs, controlthe behavior of their own members, and interactwith outside groups (Brandon 1996). Where these exist, the centralgovernment should empower them with the authorityto stop, and notjust monitor,resourcedegradation(Poffenberger 1994). When possible, projectmanagersshould use existing institutionsratherthan creatingnew ones. Communities that cooperate on irrigationprojects, markets, and sharedcropfields generallyhave capable leadership to undertakeprojects. Solutions.-Successful projectsat the communitylevel balance costs with benefits. Costs include foregoing income generatedby harvestingforestproductsand killing bears, providinglabor to projectsinstead of to more securemeansof livelihood,reducedagriculturaloutput,and crop depredation. Project planners should try to minimize these costs. For example, if the project goal is to increase a bear population,funds should be secured to employ communalcropguardsto scarebearsout of cornfields. Benefits must be realistic. People tend not to leave bears and theirhabitatalone if the benefit does not compensatetheirlost opportunities.Privateconservationorganizations in the Andes that promote environmental educationby itself, without including more meaningful benefits, fail to compensatepoor farmers. For example, 18 Andeanbearswere killed in the CapazRiver drainage (Stateof Mrida, Venezuela)despiteeducationprograms duringthe same period (1988-96) that taughtlocal residents about the need to protect Andean bears (Garcia, 1996). Local inhabitantsgenerallydo not thinktheir future livelihood will be compromisedwhen bears are ex- Peyton et al. 95 tirpatedandthe forestis replacedwith pasture.They tend to discountfuturereturnson resourceswhen they need to harvestresourcesto feed themselves (Ostrum1990), and they rarelyvalue biodiversityintrinsically. Instead,they often experiencebiodiversityin a negative sense, such as an increasedvarietyof pests that attacktheirfood crops. A betterway to create a cooperativeincentive for improvingbear populationsis to link the adoptionof costs to the provisionof benefitsthathave the most meaningto people. In descending orderthe benefits with the most value to Andeanfarmersare land tenure,access to capital (creditandemployment),politicalempowerment,technical assistance, and training opportunities. However, these are interrelated.Withouttenurelocal farmerscannot borrow money because banks do not recognize untitled land as collateralfor loans. Withoutloans farmers can not invest in the means that make their agriculture more permanent(e.g., irrigation,fertilizers, pesticides, etc.). Withoutpoliticalempowerment,communitieshave little incentiveto invest in permanentagriculturebecause the centralgovernmentor otheroutsiderscould taketheir investment away. Land tenure, access to capital, and political empowermentare not sufficient to secure bear habitat,but are essential parts of a package of benefits that can be linked to slowing down deforestation. The existence of these benefits does not guaranteesuccess, but their absence is often why community-basedconservation efforts fail (Wells and Brandon1992). Finally, technical assistance and trainingare often required to enable local participantsto use resourcesin a sustainable way that minimally harms bears. The Amuesha who live in and aroundYanachagaChemillen NationalPark(Peru)were taughtto harvesttrees in bear habitatusing a strip clear-cut method. The method allows the soil to retainnutrients,and forest regeneration occursrapidlyfromexistingseed stocks(Hartshorn1989). Unsoldtimberis madeinto charcoalwhich is used to bake potteryfor sale. Otherrevenuegeneratingactivities that can be less damaging to bear habitatthan grazing and shifting agricultureinclude tourism, alternativeagriculture (palm oil and fronds for festivals, orchids, and medicinal plants), and education. The Toroche-Protoprojectto provide irrigationwater to farms on the borderof PodocarpusNational Park in southernEcuadoris an example of how technical assistance and trainingcould be combinedto benefit Andean bears inside the park. Food productionin fields bordering the parkdeclined,forcinginhabitantsto cut new fields out of the forest above. The continuedexistence of bears in Podocarpusmay depend on increasingcrop yields on existing land. A new irrigationcanal built with technical 96 Ursus 10:1998 assistance from the park's bordermay double the yield on surroundingfarms (Knapp 1991). The link between improvedagriculturaloutputandsustainedforestrycould be improved by authorizingproject leaders to create a cooperativelyowned fund from the sale of excess production and using part of the fund to employ and train local people as parkguards. Similar funds and systems for managingthemhave been successfully establishedin Costa Rica (Donovan 1994) and Surinam(Thomsenand Brautigam 1991), where a portion of the interest is income to local farmersand the rest is reinvestedto ensure the sustainabilityof local resourceuse. Trainingin basic skills, such as recordkeeping, will be requiredto enable residentsto managethis fund. Some skillscouldbe learnedby participatingin research andmonitoringprojectsof Andeanbearpopulations.With training,Andean peasantscould learn to record data on habitatuse from bear sign, take measurementsof habitat variables such as food abundance,and gather information on humanuse of bear habitatand local attitudestowards bears. Project managerswould need to develop methods to ensure the accuracyof these data. As skill levels increased,local residentscould participatein more sophisticatedaspects of projects such as mapping bear and humanuses of landscapes. A productof such participation could include a better understandingof the community's present and estimated future use of resources. Armed with this information, communities would become more able to respond to their resource needs andto outsiderdemands. The incentivecommunities have to achieve this goal is to receive recognition fromthe centralgovernmentof theirauthorityto regulate local resourceuse. Roleof Nongovernmental Organizations Strengthsand weaknesses.-Nongovernment organizations (NGOs) are catalysts and facilitatorsof projects. Projectsoften originatefrom NGOs because they are not inhibitedfrom brainstormingsolutions by rigid bureaucracies, and they often know more about the biological and social systems thancentralauthorities.Theirknowledge helpsplannersto use existingculturaltraditionswhen designing projects,and thus enables project goals to be understoodby communitymembers. NGO ability to mobilize humanand capital resources enables them to respondrapidly to a situation. For example Arco Iris was able to stop miners from entering PodocarpusNationalParkin 1994, a year afterits founding. The marketingandcapitalmanagementskills NGOs have enablethemto analyzeresource-useoptionsfor their sustainability(May 1992). NGOs can be perceived to be politically independent. This enables them to monitorand evaluate projects and serve as intermediariesbetween central and peripheral authorities. NGO knowledge of rights and responsibilities help governmentsandcommunitiessortout landtenure and otherpropertyissues. NGOs are stronglyinfluencedby their donors' political interests which may not be what wild bear populations need. For example in 1995 the World Society for the Protection of Animals reintroduced 3 orphaned Andean bears into the MaquipucunaNatureReserve in northernEcuador. Althoughreintroductionsmay be useful vehicles to call attentionto species needs, this case was guided by what was perceived to be good for the individualbears,not the wild population.No studieswere made prior to the release on the reserve's capability to providefor the needs of wild or captivebears. Therewas no clear justification to augmentthe local bear population. NGOs need to supportfield research. In the absence of field knowledge, managementis guided more by humanvalues than the needs of bears. LastlyNGO's such as the InternationalAssociationfor BearResearchand Managementhave technicalexpertise and knowledgeto help SouthAmericansfocus theirland managementon the needs of Andeanbears. Lackingare knowledge of distributionand degreeof populationfragmentation,populationsize, habitatrequirements,andthe effect of humanson bears and theirhabitat. Most of the technicalabilityto achieve this understandingis in North AmericaandEuropewherethereis a strongemphasison using scientific researchto managebearpopulationsand humanbehavior. In contrast,AndeanNGOs emphasize the social aspectsof management(e.g., dialogue,achieving consensus, promotingself-determination,etc.) more than their northerncounterparts. They are wary about allowing foreign experts to supplantthe leadershipand institutionsof the hostcountry.Thishas inhibiteda northsouth dialogue that would benefit both parties. Solutions.-NGOs can help understaffedgovernment agencies achieve their objectives. For example, Fundacion Natura and Ecociencia in Ecuador help the government manage 3 parks with bears (e.g., Podocarpus, Cotacachi-Cayapas, and CayambeCoca). The Wildlife Conservation Society helped the Bolivian Forestry Department in 1996 to design timber harvest techniques that maintain long-term productivity of tropical forests and wildlife populations such as Andean bears. Andean governments should not become so dependent on NGOs' abilities to explore solutions and rapidly apply resources that they abandontheir decision-making functions to them. Gov- ANDEANBEARSTATUS ANDMANAGEMENT * POLICIES ernmentagencies should continuouslymonitorNGO actions to ensurethatthese actions do not conflict with national policies. AlthoughNGOs arewell suitedto providestart-upcapital and technical help to community-basedprojects,the effect of these resourcesis slight if the local institutions of authorityare weak. If they are weak, a priorityNGO action should be to strengthentheir ability to controlthe behavior of community members, and to articulatethe community'sconcernsto outside groups. Steps Andean NGOs can take in this regardare to deal separatelywith leadership and technical issues (Wray and Alvarado 1996). NGOs should be careful not to usurplocal leadershipor fosterdependencyrelationswith theirdonations (Murphree1994). ForeignNGOs need to de-emphasize regulationin favor of assistanceto local NGOs, governments, and communities(Stearman1996). By doing so NGOs build stewardshipfor bears where it counts the most and improve the skills of ruralresidents to adapt and manage their own development(Wright 1994). DISCUSSION Futureexistence of wild bears in the Andes depends on limitinghumaneffects on bearsand bearhabitat. The era of designatingparksfor bears in areasof low human habitationis rapidlyclosing. In its place is a rising human populationthat threatensto consume the resources both in and outside parks. Currently,Andean governments are strugglingto accommodatetheir swelling labor force, and increasedcapitalinvestmentis requiredto createjobs in resourcemanagementas well as manufacturingsectors (Glade 1991). The consequenceof unemployment is the huge rise of the informal economy, includingdrugtraffickingand illegal mining in protected bear areas (estimated at 39% of Peru's gross domestic product,De Soto 1989). This raises several questions. Whatis the purposeof Andeanbearconservation? How much resourcesshould we allocate to save them in light of the needs of Andean people? While the conservation community is searching for answersto these issues, we point out thatwild bear conservationin South Americacan help slow environmental degradation,perhapsenoughto enableeffective solutions to evolve. While debate continues about whetherproblems of bears and sustainedhuman use of their habitat can best be solved by a centralized authorityor at the communitylevel (Wells and Brandon1992), some roles and proceduralstrategiesare becoming clearer. The existence of a home for wild Andean bears will dependon coordinationof action,particularlyat the gov- Peyton et al. 97 emnmentlevel. Governmentsmust accept the responsibility of what happens to resources and not release that responsibilityto lower organizationallevels of society or to outsiders. The questionis: how best can governments preservewatershedsthatAndeancivilizationsdependon, and simultaneouslyconserve bears? The short-termanswer may include tough top-down measureswhere governmentsretainownershipand control. Partof Venezuela's policy to ensurethe integrityof nationalparks in the CordilleraMerida against agriculturalexpansionwas to relocate communities. However, the risks of not sharing ownership and managementof naturalresources with rural inhabitantsinclude losing controlover theiruse and having to secure them militarily. Resource managers in Venezuela and elsewhere know thatpeople with the least access to resourcesoften ignore authoritiesand take mattersinto theirown hands. In the 1940s investorsof Venezuela's oil wealthacquired large coffee plantationsand cattle ranches aroundLake Maracaibo. They pushed farmerswith small land holdings off theirland. The displacedfarmersmoved up the slopes of the Vertientedel Llano into Andeanbearhabitat,destroying2/3 of the originalcloud forestin the 1950s (Veillon 1977), a loss (12,890 km2)equal to 60% of the remainingAndeanbear distributionin Venezuela. They became violent and engaged in guerrilla activities and drug trafficking. The drug traffickingand illegal immigrationthatcame from the Colombianside of the border added to the government's difficulties to manage resources in the Perija region. By the mid 1980s, INPARQUEScalled on Venezuela's militaryto control naturalresourceuse in PerijaNationalPark(IUCN 1986, Fuerzas Armadasde Cooperaci6n 1987, Yerena 1998). Similarsocial conditionsprecipitatedthe Colombiangovernmentto use its militaryin 1994 to defend the dam in ChingazaNationalParkwhenterroriststhreatenedto blow it up. Chingaza'swatershedsupplies waterand electricity to approximately6 million residents of Santaf6 de Bogota, the capitalcity. These examples emphasizethat resource issues become national security issues unless policies enable a more equitabledistributionof income andopportunityto those on the bottomrungof the socioeconomic ladder. In the Andes these measuresare revision of policies thatlimitland,credit,technology,markets, education, and skills to poor people; the empowerment of local institutionsto play a majorrole in implementing these changes. These are the long-termsocial solutions to maintainbears. Thereis no guaranteethatlocal participationwill save wild bears; however, it is essential given the apparent trends in the status of Andean bear habitat(Brown and 98 Ursus 10:1998 Wyckoff-Baird 1992). The insecuritypoor people feel aboutobtainingbasic needs (e.g., food, clean water,shelter, clothing, health services, etc.) make it difficult for them to make bear conservationa priority. We believe the best approachis to take care of humanneeds where the most bears live and explore ways to link development with bear conservation. The degree to which the benefitsof conservationarecapturedby those who experience most of the costs will determinehow stronga link can be made. Communitieswith stronginstitutionsthat arein andaroundthelargestprotectedareas(Fig. 1) should be given priorityfor projects(see Glick andWright 1992 for criteriafor choosing sites and planningbenefits). There is also no guaranteethat donors who supported NGO efforts to keep people out of biodiverse areaswill now supportsome rural development. Foreign NGOs (e.g., World Wildlife Fund, The Nature Conservancy, Wildlife Conservation Society, Conservation International) and nationalNGOs (e.g., Fondo Andino para la Conservaci6nde los AnimalesSalvajesandFundacondor in Venezuela,Fundaci6nparala EducacionSuperiorand Fundaci6nNaturain Colombia,EcocienciaandFundaci6n Naturain Ecuador,ProNaturalezain Peru,andFundacion Amigosde NaturalezaandtheBolivianConservationData Centerin Bolivia) increasinglypromotethe concept that morebiodiversitywill remainif theyencouragesome local development. To appeal to donors, NGOs use Andean bears to symbolize biodiversity. An estimated 76% of South America's mammalianspecies occur in the 3.2% of the continent'sareaon the easternslope of the Oriental Andes (Mares1992), wheremost of the Andeanbear's range exists. The northernAndes have a greaterfloral diversity(30,000-40,000 spp.) thanwhatis estimatedfor the Amazon Basin, and far greaterthan that of Europe andNorthAmerica(Gentry1982, 1991; Hendersonet al. 1991). The cloud forest above 1,500 m in Peru where bears live contains an estimated 15% of vertebratesand vascularplantsand32%of Peru'sendemicspecies in only 5% of its landmass. On a unit area basis, that level of endemismis 5.75 times greaterthan it is in Peru's Amazonian forests (Leo 1993). The next decade will be characterizedby the building of more efficient and cooperativeinstitutionsto address the problems mentioned in this paper. Currentlythese issues are being discussed in regionalmeetings throughout the Andeanrange. To the extent thatthese dialogues result in capable partnershipsto implement action, the Andeanbear faces a brighterfuture. LITERATURE CITED H. 1963. Gold andgods of Peru.
