Post-pasture demutation in communities of the Ob forest-steppe



Influence of protection regime on natural degraded pasture areas at different stages of pasture digression was studied under the conditions of the right Ob riverside forest-steppe during the years 1994–2004. It has been revealed that the isolation of pasture phytocenoses of a steppe meadow from pasturing leads to an increase in the productivity of grass owing to different economic-botanical groups of plants. The increase in the productivity at the initial stage of digression is due to legumes and forbs, while at the final stages it is mainly due to increased mass of grasses. Removal of pasture load promotes the formation of intermediate communities; in this situation, an increase in their species diversity is to a high extent due to the adjacent floristically richer phytocenoses.
