Synopsis 



The major change is the in- 

 crease in density and cover of 

 Pinus ponderosa across the 

 landscape. Growth of individual 

 trees is apparent. Landscape on 

 left side of picture shows rem- 

 nants of a fire from 1984, which 

 left some snags and removed 

 several conifers. Cropland in 

 center of photo has existed at 

 least since 1918.
