~` Table 2.6-5. Native (potential) vegetation for determining range condition on <br />clayey foothills range sites. (1) <br />Percentage composition by weight of [he principal species may total as much as: <br />western wheatgrass 50 <br />big sagebrush 20 <br />Indian ricegrass 5 <br />mu[tongrass 5 <br />beardless wheatgrass 5 <br />Douglas rabbitbrush 5 <br />others 15 <br />(1) Tree species most likely [o grow on [he site are U[ah juniper, one-seed juni- <br />per and pinyon pine. Approximate ground cover is 40 percent. <br />Species most likely [o invade the site or increase from [race amounts are <br />juniper (at upper elevations), rubber rabbitbrush, Colorado rubberweed, <br />snakeweed, cheatgrass and annual weeds. Shadscale and greasewood move into <br />some drier parts of the site, especially those adjacent to salty soils. Big <br />sagebrush commonly becomes dominant as the range condition deteriorates and <br />may make up nearly all [he vegetation. Other plants which increase in some <br />places as the condition deteriorates are black sage and Douglas rabbitbrush. <br /> <br />2-335 <br />
