In a mulga (Acacia aneura) woodland pasture, the survival of mature grasses and their seedlings was more strongly influenced by seasonal conditions than by grazing, although heavily grazed pastures fared worst. After two years of very dry weather, very few of the plants initially present were still alive. Subsequent pasture regeneration was heavily dependent on seedlings, apparently recruited at the end of the dry period. Undesirable grasses reestablished more readily than the principal desirable ones. The implications of this for pasture management are discussed. . . . .
