variation in Total vegetal Cover 



Total vegetal cover for the 66 plots sampled at the detailed level varied from 9 

 to 80 percent. Average total vegetal cover for these plots was greater than 35 per- 

 cent for about half of the mountain ranges sampled (table 4) . Figure 3 shows that 

 higher average vegetal cover is concentrated on the high plateau of central Nevada, 

 the plateau's extensions toward southwestern Utah, and the higher elevation ranges 

 such as the IVhite Mountains of California-Nevada and the Deep Creek Mountains along 

 the Utah-Nevada border. Woodlands on the mountain ranges with lower average elevation 

 and/or lower latitudinal position have less average vegetal cover. The northernmost 

 pinyon- juniper woodlands, in southern Idaho, have higher average total vegetal cover 

 than would be expected from the low elevation of the woodlands there. In this 

 instance, latitude strongly compensates for elevation.
