|discussion=<p>Subspecies tridentata is the common sagebrush of deep, well-drained soils in the Great Basin of western North America, where it is often the dominant shrub of valleys and open grasslands. On drier sites and on high plateaus, it is replaced by <i></i>subsp.<i> wyomingensis</i>, a taxon that appears to be increasing with prolonged droughts and disturbance from grazing. In dry valley bottoms of the Great Basin, <i></i>subsp.<i> tridentata</i> is conspicuous by its great height and wide arrays of heads along roadways, fencerows, and other areas where moisture is more readily available through runoff or reduced competition.</p>
