No critical habitat has been <br />identified for federally listed species in the Basin (BLM 1984). <br />Furthermore, no essential habitats for threatened and endangered <br />species are known 1:0 occur in the project area (CDM 1983b). <br />H.5 Seasonal Use <br />Wildlife species I^equire special habitat features before any given <br />area will be utili:ted by a species. Seasonal use by wildlife species <br />of special concern needs to be seriously considered during project <br />development and operation. The most important habitat feature within <br />the grid west is the distribution and availability of water. Table <br />H-3 illustrates tFle species of special concern identified by BLM and <br />the important habitat features for these species (BLM 1984b). <br />• <br /> Seasonal use of the project area by wildlife species of special concern <br /> is limited primarily to mule deer. Mule deer use the sodium lease and <br /> project area exclu:>ively during the winter and these areas are con- <br /> sidered to be important winter habitat. Other species of special <br /> concern which occasionally use the project area include raptor species. <br /> Red-tailed hawks, Cooper's hawks, long-eared owl, and possibly sharp- <br /> sfiinned and goshawks may nest in the pinyon-juniper woodlands habitat <br /> type within the project area. The area may be occasionally used by <br /> mountain lions in conjunction with mule deer use during the winter <br /> months. Elk may migrate across the project area during some years. <br /> However, CDOW states that the area is not an important migratory route, <br /> and is not an area that is used frequently by elk (Morris 1984). <br /> Individual sage grouse may use nearby areas as wintering grounds during <br /> some years, but neither the project area nor any of the nearby area is <br /> considered to be important to sage grouse (Morris 1984). As noted in <br /> Section H.4, Thl-eatened and Endangered Species, bald eagles may <br />• occasionally use the sodium lease area (BLM 1984a).
