Photo taken by Jon Class 3: Greater than 5 Percent to 15 Percent Sagebrush Canopy Cover (Shrubland) Rangelands that exhibit a predominantly shrubland aspect are characteristic of this class (Figure 6). The 10 to 15 percent sagebrush canopy cover range is capable of supporting many of the habitat needs of wildlife species that rely primarily on sagebrush and associated understory herbaceous species. Connelly et al. (2000) reported that sage-grouse in Oregon and Idaho select winter habitat with sagebrush canopy cover as low as 12 to 15 percent, gen- erally measured above snow level. Hanf et al. (1994) reported that winter habitat selected by female sage-grouse in central Oregon was dominated by mountain big sagebrush and low sagebrush, with canopy cover ranging from 12 to 16 percent. In addition, unpublished surveys from BLM's Vale District suggested that sagebrush- obligate songbirds began to reoccupy crested wheatgrass seedings when the sagebrush canopy cover exceeded 5 percent. In Nevada, crested wheatgrass seedings with sagebrush canopy cover of about 10 percent provided structural complexity sufficient to sustain a greater diversity of grassland-nesting and shrubland-nesting nongame birds than unconverted sagebrush, monocultural crested wheatgrass, or crested wheatgrass in poor condition (McAdoo et al. 1989). Depending on ecological site potential and past and present use, grass and forb cover can be highly Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Karl,
