The grazing of domestic livestock has commonly led to decline in productivity and stability of rangeland pastures. Palatable perennial grasses decrease, ephemeral forbs increase, and inedible shrubs invade, lowering efficiency of animal prodcution. A severely degraded ecosystem is the extensive (1.6 M km2) mulga woodlands (1).. This poster paper reports the grazing pressure on perennial grasses in an eastern mulga woodland in relation to sheep density and the consequences of high grazing pressure for plant survival, seed production and recruitment.
