i-resence of anunal species as indicated by capture, sightings, tracks, <br />scats, dens, food remains, or other definitive signs was recorded on wildlife <br />. observation forms. In addition, i<~ortant wildlife habitat was noted <br />and mapped. <br />Hall and Kelson (1959) was the nomenclatural authority used for mamrals. <br />,~lurie (1954) was used for identifying anunal sign. Avian nomenclature followed <br />the American Ornothologist's Union C}iecklist of North American Birds (AOU <br />1957) as updated by the 32nd supplement to the checklist (ACU 1973). <br />INVE ~3RATES <br />Sweep-net sacc~les were used to deternune the species ea~g~osition and relative <br />abundances o° insects in the herb-forb-grass section of the t1,~o major vegetation <br />types on Che study area (see Results, page 45), Of particular concern in the <br />study was to identify groups of insects (i.e., grasshoppers) that might pose a <br />threat to %vegetation success. At five randomly selected locations in upland <br />sagebrush and grassland pasture, a sweep net sample cronsisting of five full <br />sweeps (approximately 10 mZ) was collected. Five samples also were taken from <br />. a revegetatian plot at Nucla mine. Insects were killed with cyanide gas and <br />identified and counted by a qualified entotrologist. <br />T[II2FATINFD AND ESiDANGERED WILDLIFE SPECIES <br />Accoraing to the Federal Register (January 17, 1979) five animal species <br />listed as endangered could possibly occur in the study area: <br />FuZac pererr:nus a~uttum -American peregrine falcon <br />Haliaeetus ZeucocephaZus -northern bald eag .e <br />Crus cvneric¢na -whooping crane (as a migrant) <br />D;usteZa nigripes ^- black-footed ferret <br />Caytis lupus -gray wolf <br />Based on the results of interviews with DOIa personnel and local residents and <br /> <br />-11- <br />JUM 1 1 1Q80 <br />
