%X The biomass and composition of grazed pastures near Menindee, in westem New South wales, were estimated over a range of seasonal condilions between 1980 and 1985. Differences in biomass and composition of pastures grazed separately by kangaroos and by a mixture of sheep and kangaroos were minor. Pasture biomass ranged from 7 kgha during a drought to 1,100 kgha following high summer rainfall. Overall, biomass average 374 kgha with a slandard deviation among years of 302 kgha. Pasture biomass fluctuated markedly among calendar seasons and years in response to erratic rainfall and grazing. I-Iigh summer rainfall triggered a switch in pasture dominatnace from annuals to shoa-lived perennials.
