Figure 2. Environmental strata within the mapped extent of the sagebrush-grass scrub vegetation type. Each color represents a unique combination of high or low vegetation density index, standard deviation of vegetation density index, slope, elevation, and distance from stream. White areas represent the other seven vegetation types (strata not shown).
