Discussion
In the Great Basin and Mojave deserts, Coleogyne ramosissima 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 C. ramosissima. 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).
In some areas Coleogyne ramosissima 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.
