Section 779.20 (c) Continued. • At lower Foidel Creek the stream was electrofished in an upstream direction from the road crossing to the dam of the small impound- ment or about 100 yards. Approximately 200 yards of stream were fished in an upstream direction (about 100 yards above and below the USGS gaging station) cn lower Fish Creek. All fish captured were identified to species, measured, and condition noted. Results of Wildlife Habitat Investigations Small Mammals. A total of twenty-one mammal species were recorded during the study shown in Table 44 Total Number of Observations of Mammalian Species on Proposed Mine Expansion Area During August, 1975. Nomenclature in Table 44 follows that of Armstrong (1972). Aspen and oak brush had the greatest diversity; 14 and 13 species respectively; eight species were recorded in sagebrush and only two in dry meadow. Oak brush and aspen supported a more diverse mammal • fauna than sagebrush or dry meadow because a greater array of microhabitats is associated with woodland growth-form. Many mammals utilize more than one community (See Table 44, Total Number of Observations of Mammalian Species on Proposed Piine Expansion Area During August, 1975. Among small mammals, all species trapped in 1975 occurred in woodland and oak brush areas, but only deer mice were trapped in sagebrush and meadow communities. Since the diversity was greatest in oak brush followed by aspen woodlands, these two communities appear to be the more important habitats for small mammals. The six species trapped in oak brush range from carnivorous to seed and vegetation consumers, suggesting not only a diverse habitat but a diverse food resource base within this community. The mammal composition in dry meadow and sagebrush was less diverse than in the woodland communities. Of the eight species recorded • in sagebrush and the two in dry meadow (see Table 44, Total Number 779-147
