Synopsis 



Density and cover of Pinus 

 ponderosa growing on Judith 

 Mountains in background have 

 increased dramatically over 

 time. So have the density and 

 cover of riparian shrubs, par- 

 ticularly Symphoricarpos 

 occidentalis, Prunus virginiana, 

 and Crataegus succulenta. 

 Although the upland herbaceous 

 vegetation in the foreground is 

 species rich, upland vegetation 

 in the background is largely 

 dominated by Agropyron smithii 

 and Poa pratensis.
