Stability of grass ecosystems

Two aspects of grass ecosystem stability are considered theoretically: (1) the ability to maintain structures and functions and (2) the ability to recover them after disturbances. The low resistance of the species structure of grass community and the high stability of biotic turnover are demonstrated. In spite of low resistance, the species structure of phytocenosis possesses high resilience, which is expressed in its rapid recovery upon removal of stressing impact.
