Comparative analysis of species composition and productivity of feather kovyl-forb steppe pastures of Central Asia

Based on all the studied parameters investigated steppe pastures: small projective cover, low species diversity, low stocks dead (litter) and live aboveground biomass, with the exception of some communities of the Inner Mongolia and forb - feather (kovylnoe) communities of Mongolia and widespread grazing resistant plants, such as Artemisia frigida, Potentilla acaulis, Carex duriuscula and Leymus chinensis one can mark their moderate pasture transformation. Therefore, to improve the efficiency of the use of these plant resources should be optimized steppe pastures. Special measures to restore and enhance the productivity of steppe pastures to Buryatia, where there is a significant impoverishment of flora and significant low stocks of dead and living phytomass must be taken.
