Abstract
Abstract Mongolia's Eastern Steppe is one of the largest remaining temperate grassland ecosystems and is habitat for Mongolian gazelles (Procapra gutturosa). During four surveys, we quantified vegetation composition, forage quality, and trace elements to gain insights on characteristics of forage that could be influencing how gazelles are distributed across the steppe. Grasses made up between 57% and 68% of all species, Stipa spp. (24–42% of all grasses) being the most abundant. Forbs made up 6% to 23% of all species with Allium spp. (11–44% of all forbs) the most abundant. The shrubs and dwarf shrubs were least common (7% and 12% of all species) with Artemisia frigida Willd. (18% and 47% of all shrubs) most common. Spring crude protein values of green vegetation averaged 21.9%. Considered an important forage for gazelles, Stipa spp. was below optimum value in phosphorous (P) and magnesium (Mg). The forbs Allium spp. and Astragalus spp. and the dwarf shrub Artemisia frigida had some of the highest crude p...
