STANDARD 1 - Upland Watershed -Upland soils exhibit infiltration and permeability
rates, moisture storage, and stability that are appropriate to soil, climate, and
landform.
Overall the allotments in this assessment including 44,512 acres of BLM administered
land, are functioning properly, and meeting the standard as indicated by the distribution
and amount of ground cover, long-term trend studies, upland forage utilization surveys
and SSF data compiled from ESL
Indicators used to evaluate this standard are Soil Surface Factor (SSF) which documents
erosion class and soil susceptibility to accelerated erosion; plant community composition
which indicates the root capacity of the soil profile; grazing management, and existing
vegetation monitoring (forage utilization and trend studies). Ecological Site Inventory
(ESI) is preliminary and is used for estimation purposes only. Field surveys for ESI were
done from 1996-2000 for this area. Please refer to allotment specific tables for full
vegetative data including plant species, soil surface factor, observed apparent trend and
ecological status.
SSF data is available on 78% of the area. The acreage without data represents vegetative
areas too small to be mapped, transition zones between vegetative communities and soil
types, and rock outcrops. The majority of the area has an SSF rating of stable to slight,
19% is moderate and less than I % is critical. The recommended grazing systems from the
Lakeview Grazing EIS have basically been followed for the last 20 years throughout the
assessment area. Overall grazing management is maintaining a healthy perennial
vegetative cover which assists in properly functioning soil properties.
Another indicator of Upland Watershed is plant composition and structure. There are at
least 22 different vegetative communities in the assessment area with a diversity of grass,
shrub, and forb species. Overall a diverse plant community exists to provide root systems
throughout the soil profile, providing soil stability and water storage within the plant and
soil systems.
A small percentage (9%) of the overall acreage is recommended for juniper treatment and
restoration projects. These areas are shown in the attached tables and are dominated by
cheatgrass, or juniper and lack diversity in perennial species especially herbaceous and
shrub species. Dominance by a single species reduces the overall root capacity to
stabilize soil and store water within the plant community.
4
STANDARD 2 - Riparian/Wetland-Riparian-wetland areas are in properly
functioning physical condition appropriate to soil, climate, and landform.
The two allotments in this assessment are meeting this standard based on palustrine and
lacustrine surveys. There are no major intermittent or perennial streams. There are 28
acres of palustrine wetlands and 52 acres of lacustrine wetlands that were rated in PFC.
There have been no recent lentic PFC or surveys performed in these allotments. If
surveys are completed in the future, and it is determined that the standard is not being
met due to livestock grazing, appropriate management actions will be taken to bring the
sites into properly functioning condition.
STANDARD 3- Healthy productive and diverse plant and animal populations and
communities appropriate to soil, climate, and landform are supported by ecological
processes of nutrient cycling, energy flow and the hydrologic cycle.
A review of the range monitoring data (photos, trend transects, climate, field observations
OAT) and professional judgment indicate that overall the assessment area is meeting this
standard.
Indicators used to evaluate this standard include animal populations, vegetative
composition, presence of weed species, botanical reports, ecological status, OAT, current
plant composition as compared to a defined Potential Natural Community (PNC) for the
soil type and precipitation zone. SSF, OAT, Range Site, Seral Stage and PNC are from
the Lake County ESI survey. Please refer to the Tables presented in the Allotment
Overview for summary of ESI data. Field surveys for ESI were completed in 1996-2000.
Data is currently being reviewed and updated and is used for estimation purposes only.
The vegetation data presented in ESI tables along with the list of plant species recorded
on field reviews shows the overall diversity of plant species in the assessment area.
The ESI survey compares the current plant composition to a defined Potential Natural
Community for the identified soil type and precipitation zone. Using the 1997-2001 ESI,
2% of the native plant communities are at PNC, 41 % are in Late Seral, 27% are in Mid
Seral and 4% are in Early Seral. Overall the area supports healthy diverse plant
communities.
Observed Apparent Trend (OAT) is a one time trend for the area determined in the 1996­
2000 ESI survey. 78% of the area had a static to upward OAT. 22% had a downward
trend. The majority of downward trend appears to be attributed to and old fire in the
southwest portion of the allotment and to cheatgrass dominating a two small areas in the
north part of the allotment. The downward trend is not attributed to current livestock
grazing practices.
Botany Report
Special Status Plants: Cymopterus nivalis is documented in Allotment 419. This plant is
on the BLM Bureau Assessment list, ONHP List 2. There are 6 populations known in the
Lakeview Resource Area. The plant species list described in Standard 5 shows the
diversity of plant species in the assessment area and indicates the area meets the standard.
5
Weeds A few noxious weeds are known to occur in the assessment area. Medusahead rye has potential of expanding into this area. Treatment of medusahead over large acreages on BLM is difficult. Under the Court injunction on herbicide use in Oregon, selective chemicals for medusahead treatment are not available and there are no proven biological control agents. Mechanical treatment is not practical over large acres of rugged terrain, and would need to be used in combination with some other method such as chemical or biological. Prevention measures are in place to reduce the likelihood of spreading medusahead to new areas and research is underway to explore treatment and restoration of medusahead infested sites. Along Highway 31 there are a few small historic patches of musk thistle and diffuse knapweed. These species have been controlled and the previously infested areas are inspected annually for new or returning weeds. Mediterranean sage and bull thistle are common in the Assessment area but not over large areas and are not widespread. Known sites are under treatment. Wildlife Report Much of these two allotments support healthy diverse wildlife populations. Wildlife habitats are threatened by a few small areas of noxious weeds within portions of allotment 420. Invasive species like medusahead rye and Mediterranean sage occur in small isolated areas, but will increase and spread when the next major disturbance or wildfire occurs. Ongoing efforts are underway to curtail the spread of these two species. There are adequate levels of species diversity within these allotments. This standard is currently being met from the aspect of wildlife populations and diversity. STANDARD 4- Surface water and groundwater quality, influenced by agency actions, complies with State water quaJity standards. This standard is met at this time, because neither the surface water nor groundwater within the allotments has been listed for exceeding State water quality standards. 6
STANDARD 5- Native, T&E, and locally important species. Habitats support
healthy, productive and diverse populations and communities of native plants and
animals (including special status species and species of local importance)
appropriate to soil, climate and landform.
This standard is met at this time based on the following botany and wildlife information. Botany Report Native plant species in the assessment were recorded on visits to the area in December 2003 and March 2004. The following Native Plant Species were found: Agropyron spicatum, Arabis sp., Artemisia arbuscula, Artemisia tridentata var. tridentata, Artemisia tridentata var. vaseyana, Artemisia tridentata var. wyomingensis, Astragalus sp., Chrysothamnus viscidiflorus, Cryptantha sp., Danthonia sp., Eleocharis sp., Elymus cinereus, Elymus elymoides, Epilobium sp., Ericameria nauseosus, Festuca idahoensis, Iva axillaris, Juniperus occidentalis, Lomatium sp., Oryzopsis hymenoides, Poa secunda, Stipa comata, Stipa thurberiana, and Zigadenus venenosus. Special Status Plants: Cymopterus nivalis is documented in Allotment 419. This plant is on the BLM Bureau Assessment list, ONHP List 2. There are 6 populations known in the Lakeview Resource Area. There are no special status plants documented in Allotment 420.
Locally Important Plant Species: No cultural plants were noted during the field trips to
the area.
Wildlife
Special status wildlife species or their habitats that are present within these allotments
include the bald eagle (Haliaeetus leucocephalus), ferruginous hawk (Buteo regalis),
peregrine falcon (Falco peregrinus), burrowing owl (Speotyto cunicularia), kit fox
(Vulpes macrotis), sage-grouse (Centrocercus urophasianus), and pygmy rabbit
(Brachylagus idahoensis). There are also three species with high public interest. These
are mule deer (Odocoileus hemionus), California bighorn sheep (Ovis canadensis) and
pronghorn antelope (Antilocapra americana).
No nesting habitat exists within these allotments for the bald eagle or peregrine falcon. It
is suspected that they are occasional visitors to the area. No incidental sightings of
peregrines exist within the vicinity of these allotments. There are no good foraging areas
for peregrine falcons within close proximity of these allotments. No surveys have been
conducted for ferruginous hawk. Ferruginous hawk foraging habitat exists through
much of these allotments. Bald eagle foraging does occur within the allotment; however
it is probably restricted mostly to road killed deer adjacent to the major roadways and
occasional carrion scattered through the allotments. There are no resource conflicts for
peregrine falcons, ferruginous hawks or bald eagles.
7
Burrowing owls have been observed at a few locations within these allotments. No nest
burrows have been observed in either allotment. There are no resource conflicts for this
speCIes.
Habitat is present for kit fox, but no known locations exist within the allotment for this
species. No inventories have been conducted for kit fox within the allotment, however
they are suspected to occur within portions of the allotment. There are no resource
conflicts for these species.
Pygmy rabbits occur in at least one sight in allotment 419. Only isolated surveys have
been completed for this species. It is suspected, however, that pygmy rabbits occur in
several isolated pockets within both allotments. Additional surveys are scheduled for
2005 within these allotments. No conflicts exist for pygmy rabbits within these
allotments.
Bighorn sheep are occasional visitors to both allotments. Scattered broken rims provide
habitat scattered across both allotment. Most habitats within these allotments are only
used seasonally by bighorns. There is moderate overlap in range between bighorns and
cattle within these allotments. No major conflicts exist between bighorn sheep and cattle
grazing within these allotments.
Pronghorn antelope are common in both allotments. Pronghorn use is scattered across
portions of these allotments that have low sagebrush or short stature Wyoming big
sagebrush. No major conflicts exist between pronghorn and cattle grazing within this
area.
Mule deer inhabit much of the area, but are widely spread and in low numbers. No high
concentrations of wintering mule deer inhabit these allotments. No conflicts exist
between mule deer and cattle grazing within this allotment. Bitterbrush is not very
abundant and sagebrush browse use appears to be somewhat stable at this time.
There are 6 known active sage-grouse 1ek sites within these allotments. Five are located
in allotment 420 and one located in allotment 419. Most of these allotments are currently
within active sage-grouse habitat. Much of the allotments are available for sage-grouse
nesting and brood rearing habitats. There are portions of the allotments where there is a
lack of native understory plants and cheatgrass is common. These areas are not currently
much of a threat to sage-grouse habitats. In order for sage-grouse habitats to improve
within these allotments, steady upward or stable trends in range conditions are needed.
No major conflicts exist between cattle grazing sage-grouse within this allotment at this
time.
Overall, this standard is being met for wildlife species within these allotments. The
occurrence of scattered areas of noxious weeds and native ranges with poor understory
forbs and grasses appear to be the limiting factors for sage grouse and most sagebrush
wildlife habitats. Efforts to improve this standard should focus on control of noxious
weeds and maintaining an increasing trend in range condition.
