Grasses dominate the vegetation of both plots (fig. 8). 

 In addition to the two dominants, Festuca scabrella and 

 F. idahoensis, Koeleria cristata and Agropyron spicatum 

 are the most abundant grasses. Lupinus sericeus, 



Achillea millefolium, and Solidago missouriensis are 

 common on both plots, but many of the less common 

 species were only found on one or the other of the plots. 

 Despite a similarity index of 65 percent, the two plots 

 have only 15 of 35 species in common.
