page-4 ` intervals in aspen habitat and at 30-ft. intervals in reclaimed sites. Detection distances for each bird species was selected at the point where calculated densities consistently declined. It was necessary to select a reasonable observation distance for some of the more rare birds. Bird densities were compared among overstory categories with analysis of variance at P=0.05. Differences among overstory categories were determined with the Newman-Keuls test (Lund 1985). Bird diversity profiles were prepared following Patil and Taillie (1979). Lines within the profile that cross are not significantly different (P=0.05), whereas lines that do not cross are different. Correlations were made with bird densities on each sample plot with eight habitat variables. Birds were separated into nesting and feeding guilds for discussion and were compared with analysis of variance for difference in density at P=0.05. RESULTS VEGETATION AsAen sites. The selected aspen sites had several exploratory roads with grasses and forbs in the area, which provided some edge effect. Tree density was higher (1036 stems/acre) than on the aspen-edge habitat (836 stems/acre), and interior aspen (835 stems/acre), and shrub understory was slightly greater in aspen than aspen-edge and interior aspen (Table 1). Canopy cover was higher for interior aspen sites than for aspen and aspen-edge. Reclaimed sites. Reclaimed 1 site was reseeded in 1981 and consisted of a good ground cover of forbs and grasses. Reclaimed 2 also had good ground cover but reclamation was partially with live top soil and was reclaimed in 1980-81. The reclaimed-edge habitat was reclaimed more recently (mostly in 1982-83), and ground cover was less abundant than the reclaimed 1 and 2 sites. Shrub cover was low for both habitats (less than 1~), but reclaimed 1 and 2 were higher than the edge habitat. Tree pads were more abundant on the reclaimed sites than on edge, but the edge sites were about 100 feet from an aspen woodland. Reclaimed edges had higher grass and forb dominance ratings even though there was noticeably less ground cover on the edge sites. Mountain shrub sites. The mountain shrub sites were slightly lower elevation than the aspen sites and about the same elevation as the reclaimed sites. They were located across a narrow canyon from the aspen sites and were about 1/4 mile from the aspen 2 transects. Tree density was higher than any of the aspen sites; however, the trees were much smaller and no aspen were present. Canopy cover was considerably less than the aspen sites and shrub cover was higher than other sites.
