HABITAT TYPES AND PLANT COMMUNITIES : 
Cheatgrass is not a climax dominant or indicator species in any habitat
type classification because of its role as a seral invader after
disturbance.  However, it can maintain its dominance for many years on
sites where the native vegetation has been eliminated or severely
reduced by overgrazing, cultivation, or frequent fire.  In these
situations, cheatgrass remains the de facto climax dominant regardless
of the site potential.
