Detailed Description
Sagebrush-steppe landscapes have changed in fundamental ways over the past 100 years. In general, the area of land dominated by sagebrush has decreased, plant community composition at low-elevation sites has become dominated by non-native annual grasses, trees have expanded downslope from high-elevation sites to dominate lower slopes and valleys, and large patches of non-native annual grasses have fragmented habitats.
