<br />i-resence of a,,:t„at species as indicated by capture, sightings, tracks, <br />scats, dens, food rAna<~4, or other definitive signs was recorded on wildlife <br />observation forms. In addition, important wildlife habitat was noted <br />and mapped. <br />Ra11 and I;elson (1959) was the nomenclatural authority used for n~axm~als, <br />Marie (2954) was used for identifying ariinal sign. Avian nomenclature followed <br />the American Ornothologist's Union Checklist ~of North American Birds (T.OL7 <br />1957) as updated by the 32nd supplesent to the checklist (AG(J 1973). <br />IAZ/EFYI'EE3I2AZ1'S <br />Slueep-net samples wem used tD det,eunino the species cafq~osition and relative <br />abundance o° insects in the herb-fort-grass section of the two major vegetation <br />types on the 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 revegetation success. At five randanly selected locations in uplanc <br />r sagebrush and grassland pasture, a sweep net sample consisting of five full <br />sweeps (approximately 10 mz1 was collected. Five sattgles also were taken fmm <br />a revegetation plot at Nucla mine.
