Aspen ( Populus tremuloides ) stands usually occur on moist sites adja- 

 cent to or among conifer stands. The aspen forest type was sampled at ele- 

 vations of 4,200 to 6,300 feet. The most commonly associated species were 

 lodgepole pine and ponderosa pine. 



Periodic wildfires seem necessary for aspen stands to perpetuate (Pfister 

 et al. 1977). In areas where wildfires have successfully been suppressed, 

 aspen stands seem to be succeeding towards conifer stands. 



Aspen is not an important commercial species in Working Circle 3. How- 

 ever, there has been some recent experimentation in using aspen as feed for 

 cattle.
