A survey of 50 old field evaluation experiments in coastal northern New South Wales and southern Queensland revealed that Aeschynomene falcata cv. Bargoo had persisted in all these experiments and had usually spread from the original plots. Seed reserves of Bargoo in the topsoil at six of these sites averaged 4000 m-2 (range 1150 to 7560). These levels are high for a pasture legume that is a perennial.
