Roadside Wildlife Survey 



Each of the five roadside wildlife survey routes were run in May, 

 June, and July, 1978, using methods outlined in the WBS and follow- 

 ing the 1977 dates as closely as possible. The theoretical total 

 number of species (St) was determined for cumulative sample abundance 

 distributions as breeding-season (May-July) data were pooled for (1) 

 each route, and (2) the five routes combined. The average sample abundances 

 of each indicator species were plotted in order to graphically portray 

 the nature and magnitude of year to year fluctuations. 



Factor analysis (principal component analysis) was used to analyze 

 between-year (and, in some cases, between-month) differences in breeding 

 season habitat use for selected species. May-July sample abundance data 

 for each of the 250 roadside wildlife survey stops, as well as habitat 

 descriptions for each stop, provide the data base. Habitat descriptions 

 included in the analysis included elevation and the percentages of the 

 following habitat categories: grassland, cultivated, saltgrass, blue- 

 bunch wheatgrass. Rocky Mountain juniper, little bluestem, badlands, 

 big sagebrush, badlands plus big sagebrush, silver sagebrush, big sage- 

 brush plus silver sagebrush, horizontal juniper, wild hayland, buildings, 

 snowberry/rose, cattail marsh, alfalfa, tall shrubs, trees, and tall shrubs 

 plus trees. 



B reeding Bird Census 



In 1978, the five breeding bird census grids established in the 

 baseline study were censused using standard methods. 



Small Mammal Trapping 



Eight small mammal traplines (numbers 15, 17, 18, 20, 33, 34, 35, 

 and 44) were snap-trapped for three consecutive nights in May and again 

 for three consecutive nights in October using methods outlined in the 

 WBS. 



Lagomorph Survey 



The two lagomorph survey routes were run consecutively on each of 

 three mornings (October 6-8) beginning with the mining area route at 

 4:00 A.M.
