Sagebrush-Grassland Complex. The sagebrush-grassland communities in Yellowstone and Grand Teton are located in dry environments generally below 7500 feet. This complex is generally confined to broad valleys and plateaus which are blanketed with sagebrush. The prevalence of sagebrush may be due, in part, to past fire suppression. The groundcover in the sagebrush-grassland complex consists primarily of bluebunch wheatgrass, Idaho fescue, Junegrass, and a variety of wildflowers. Along the edges of this complex juniper, aspen, and Douglas-fir grow in scattered clusters. Pothole lakes in these areas attract many birds. In Grand Teton sagebrush complexes occur primarily on gravelly glacial soils. Several sagebrush-grassland complexes in Yel- lowstone occur on glacial deposits. These include Hayden Valley, Pelican Creek, portions of Lamar Valley, the upper Gardiner River drainage, an area near Lewis Lake, and the area surrounding Yellowstone Lake. In Grand Teton extensive areas of the sagebrush-grassland complex can be found over the entire valley floor. 9.
