Absolute cover by lifeform was as follows: <br />frees--18.3 percent, shrubs and subshrubs--16.0 percent, perennial <br />graminoids--12.9 percent, perennial fortis--2.4 percent, succulents-- <br />0.3 percent, annual (orbs--0.3 percent, cryptogams--0.3 percent, and <br />annual graminoids--0.1 percent (Table 61. <br />Trees comprised about 33 percent of the relative cover. <br />Pinyon pine was generally dominant with 12.4 percent absolute cover <br />and one-seed juniper was a secondary species with 1.9 percent cover. <br />Ponderosa pine and Douglas-fir averaged only 2.4 and 1.4 percent cover, <br />respectively.

Rocky Mountain juniper l'funipeitu~ <br />~cvpu.iv2uml accounted for only 0.2 percent cover, and was generally <br />associated with ponderosa pine and Douglas-fir. <br />A variety of shrub species accounted for about 32 percent <br />relative cover. Gambel's oak If„~eacv~. ymabe.liil was the most common <br />species with 11.7 percent absolute cover. Cover of Gembel's oak varied <br />from extremely sparse on dry, southern exposures, to very dense thickets <br />in more mesic areas. Mountain mahogany was alsc conrran with 2.9 percent <br />cover.
