Introduction Section 7 of the Endangered Species Act of 1973, as amended, requires federal agencies to "ensure" that actions authorized, funded, or carried out by them are not likely to jeopardize the continued existence of endangered (E), threatened (T) or proposed (P) species, or result in the destruction or adverse modification of their critical habitats. Also, the Forest Service established direction (Forest Service Manual 2670) to guide habitat management for endangered, threatened, proposed and sensitive species to ensure that these species receive full consideration in the decision-making process. That direction establishes the process, objectives, and standards for conducting Biological Assessments (BA) and Biological Evaluations (BE). The R-6 supplement to FSM 2672.4 identifies a four-step procedure for conducting a BA or BE. The steps are: 1. Pre-field review of existing information, 2. Field reconnaissance of the project area, 3. Risk assessment if species or habitat is present, 4. Biological investigation if data sufficient to complete step 3 do not exist. This BE contains the analyses of the effects of the proposed Deer Jasper Project (Figure 1 and attached project map) after the 2015 Stickpin fire on endangered, threatened, or proposed wildlife species listed by the US Fish and Wildlife Service (USFWS) as having the potential to occur within or adjacent the project project area. The USFWS stated that the following species might occur within or adjacent the area (letters from USFWS on file at the Colville National Forest’s (CNF) Supervisor’s Office): US Fish and Wildlife Service Threatened or Endangered species Woodland caribou Grizzly bear Canada lynx (Endangered) (Threatened) (Threatened) US Forest Service sensitive wildlife species (US Forest Service 2011).

Dragonflies/damselflies Zigzag darner (Aeshna sitchensis) Subarctic darner (Aeshna subarctica) Subarctic bluet (Coenagrion interrogatum) Delicate emerald (Somatochlora franklinii) Whitehouse emerald (Somatochlora whitehousei) 3. Mollusks Fir Pinwheel (Radiodiscus abietum) Magnum Mantleslug (Magnipelta mycophaga) Habitat does not exist in the project area for the following species, this project would either have no effect or no impact to them or their habitat, and they will not be discussed further in this document: Common loons, bald eagles and eared grebes nest on large bodies of water, which do not occur in the project area. Sandhill cranes occupy open, wetland habitat which does not occur in the project area. Harlequin ducks reproduce on cold, high-gradient streams, which do not occur in the area. Harlequin ducks do migrate through the area, the most recent record coming from northeast of the project area (Pierre Lake) on April 25, 2008, and others dating from the early 2000s on Sherman Creek, about 10 miles east of the project area. American peregrine falcon nests have been documented only in the Pend Oreille Valley. The project area does not contain suitable nesting or foraging habitat. Bald eagles nest near large bodies of water containing abundant fish or waterfowl, neither of which occur in the project area. Roosting occurs near nesting areas. Woodland caribou: the nearest recovery area is over 2 mountain ranges and 2 rivers from the project area. Mountain goats occupy higher elevation, primarily rocky and open areas, which do not occur in or near the project area. Red-tailed chipmunks and pygmy shrews occupy dense, more mesic coniferous forests east of the Columbia River and do not occur in the project area (Washington Department of Fish and Wildlife’s Gap Analysis Program). Great Basin fritillary occurs far to the south of the CNF. The single individual caught just south of the CNF boundary was misidentified (J. Pelham, pers .comm.) Zigzag darner, Subarctic darner, Subarctic bluet, Delicate emerald, and Whitehouse emerald. All these odonates occupy high-elevation open-water wetlands, which do not occur in or near the project area. 5 D. Analysis comments We conduct unit-by-unit analysis by computerized mapping. Computerized mapping can give a false sense of accuracy and precision for 3 main reasons. First, the computer provides inflated precision and accuracy, far greater than that of our mapping. Second, maps project a 3- dimensional surface onto a flat, 2-dimensional medium. Third, computer-generated maps look very accurate, but the resulting data are only as good as the map information entered into the computer. To prevent ourselves from portraying a false sense of accuracy, we round the acreage values for each unit's effects to the
