Abstract

Thirteen grasses and sixteen legumes were tested for their ability to revegetate exposed sand mine areas near Braidwood in the Southern Tablelands of New South Wales. These areas have a high erosion potential. The trial began in 1975 on a site devoid of topsoil. The best grasses tested were perennial ryegrass (Lolium perenne), cocksfoot (Dactylis glomerata), phalaris (Phalaris aquatica) and lovegrass (Eragrostis curvula). Demeter fescue (Festuca arundinacea) showed good potential but was susceptible to complete removal by grazing. Of the legumes used, New Zealand white clover (Trifolium repens) performed the best. Red clover (T. pratense) and lucerne (Medicago sativa) germinated well but did not survive periods of moisture stress. White lupin (Lupinus angustifolius cv. Uniwhite) and blue lupin (L. digitatus cv. Boree Blue) exhibited excellent potential but were susceptible to removal by grazing in early growth stages. Aspects of revegetation techniques which require further investigation are discussed.
