FORAGE VALUE 



Major species of the understory vegetation are given in table 1. We computed 

 species composition on each site from percentage aerial crovv-n cover. Separate palata- 

 bility ratings for cattle, sheep, and elk were assigned to each of the species that 

 contributed 3 percent, or more, to the cover on at least one site. Ratings ranged from 

 to 6, with a rating for unpalatable plants and a 6 rating for excellent species. 

 Species contributing less than 3 percent of the cover were arbitrarily rated 3, about 

 midway in the scale. Sources consulted for information on palatability included Dayton 

 (1960), Hayes and Garrison (1960), Hermann (1966), and USDA Forest Service (1937). 



Table I . --Composition^ aerial aroun cover, and frequency of vegetation on 

 lodgepole pine clearcuts. Includes only those species contrib- 

 uting 2 percent or more to the vegetal cover on at least one site 

 and occurring on at least 4 of the 25 sampled sites
