Sustainable grazing management systems need to be both economically viable and environmentally sustainable. Pasture spelling is now widely recommended, with its timing of great importance. Three key perennial grasses were investigated to determine their response to timing of spelling and defoliation rate. Markedly different responses were obtained between treatments over one wet season, with Mitchell grass increasing in basal area for some treatments, bluegrass showing mixed response and wiregrass declining. Investigations of longer duration will be undertaken to determine consistent results.
