PNII~L DISTRIB[TPICN S'I47DIF5 AND DCx[II~PPATiCN OF ANIMAL PAGSENCE • <br />Animal distribution on the project site was determuted on the basis of a <br />compilation of wildlife observation data obtained during field investi- <br />gations and from previous data obtained by the DOW, Peabody Coal Con~any, <br />and others. Canpiled information was plotted on study area maps to <br />depict the distribution of the following important wildlife groups: <br />1. I~h~le deer <br />2. Elk <br />3. Raptors and raptor nest sites <br />4. Waterfowl <br />5. Upland game birds <br />6. Mammalian predators <br />Presence of animal species as indicated by capture, sight; mss, tracks, <br />scats, dens, food remains or other definitive signs was recorded on <br />wildlife observation forns. In addition, important wildlife habitat • <br />was noted and mapped. <br />Hall and Kelson (1959) was the ncn~enclaturai authority used for manmals. <br />Murie (1954) was used for identifying animal sign. Avian nomenclature <br />followed the American Ornithologists' Union Checklist of North American <br />Birds (AOU, 1957) as updated by the 32nd supplement to the checklist <br />(AOU, 1973). <br />Sweep net samples were used to determine the species ~iposition and <br />relative al~inr3anCe of insects ]S1 the herb-forb-grass section of the <br />too major vegetation types on the study area. A particular concern <br />of the study 'eras to identify groups of insects (e.g., grasshoppers) <br />that might pose a threat to revegetation success. At five randomly <br />selected locations in mixed brush and upland sagebrush vegetation, a sweep <br />net sample consisting of five full sweeps (approximately 10 m2) was o01- • <br />lected. Five samples were taken fran a revegetation plot at Seneca II <br />-14- <br />
