Perennial grasses: their uses and impacts in agricultural systems
Tim Prance, Rural Solutions SA, PO Box 1439, Victor Harbor, South Australia 5211, Australia.
Summary
Perennial grasses are very important for soil protection, managing water use and nutrients, and livestock production. There will always be someone, somewhere, at some time, who wants to try something different in the way of new perennial grass species. Hence there should be a mechanism for evaluating perennial pasture plants before they are introduced. Most, if not all, of the factors that make a perennial grass a potential weed are under the control of the grazier, in particular grazing management. We must learn to understand our ecosystems, so we can manage them appropriately.
