Conteúdo:  Many native, naturalised, and low-input pastures have a low proportion of densirable species. Under the prevailing economic conditions, it is unikely that these pastures would be replaced with sown native species as there may not be seed of suitable cultivars available and costs would exceed returns. Better management is a preferable strategy to improve the proportion of desirable components. Grazing tactics are central to any improved management strategies for these pastures as they offer a lower cost option for land managers. Additional tactics, which will vary depending upon specific circumstances, include some use of fertiliser (to increase the rate of change), herbicides (where weed problems are particularly severe and animals are unlikely to eat the "weeds"), and fire (to reduce dead material and seed numbers and produce green leal for grazing). Several examples of manipulating pasture composition are considered. In situations where the desirable species are C3 perennial grasses (e.g., Danthonia spp., Microlaena, and Dactylis), and the less desirable are C3 annual species (e.g., Vulpia), rests over the summer period, especially in wetter years, improved the perennial grass content. In addition, extra grazing pressure in spring limits seed set by annual grasses. Where the undesirable species are C4 perennial grasses (e.g., Bothriochloa and Aristida), heavy summer grazing is more important. In some instances, the timing of a heavy grazing period will depend upon monitori... Mostrar Tudo
