Synopsis 



A fire went through this area in 

 1984, causing a major decrease 

 of Pinus ponderosa. The ridges 

 in this picture are dominated by 

 shrub species, predominantly 

 Rhus trilobata. Grass is sparse 

 in the foreground but is much 

 more apparent in the lowlands. 

 Agropyron smithii dominates the 

 lowland and upland vegetation. 

 However, Bromusjaponicus and 

 Poa pratensis have invaded 

 some localized areas.
