Forty different legume accessions were sown into cultivated strips in otherwise undisturbed grassland at 2 sites in southern coastal Queensland in 1969. The accessions were primarily from cultivars and selections of Kummerowia (formerly Lespedeza) stipulacea obtained from the USA, together with other accessions of lespedeza. Some commercially released cultivars, including Macroptilium atropurpureum cv. Siratro and Aeschynomene falcata cv. Bargoo, were sown as controls. Grazing was controlled in the first 4 years after sowing, but after that the sites were open to farm grazing. The sites were regularly inspected for the first 5 years and then at 5–15 yearly intervals until 1999.
