|discussion=<p>In the Great Basin and Mojave deserts, <i>Coleogyne ramosissima</i> is the dominant shrub in areas of shallow soils underlain by a caliche layer (S. A. Lei and L. R. Walker 1997). In deeper soils, grasses and other shrubs prevent dominance by <i>C. ramosissima</i>. The species has a notably long life span; seedling establishment is rare in arid sites but is more likely at higher elevations and in cooler portions of the species's range (R. H. Webb et al. 1987; S. E. Meyer and B. K. Pendleton 2005).</p><!--
--><p>In some areas <i>Coleogyne ramosissima</i> provides important cover and winter browse for mule deer and desert bighorn sheep (D. L. Jeffries and J. M. Klopatek 1987). It is used to a much lesser extent by domestic livestock. B. K. Pendleton and R. L. Pendleton (1998) show the species is wind pollinated.</p>
