The tree legume, Albizia lebbek (Indian siris), although known elsewhere as a useful forage tree and planted for shade in Queensland, has never been grown for feed in northern Australia. Measurements from trees in the Townsville area show that mature trees in open woodland can make substantial edible dry matter available without cutting or browsing through the natural seasonal fall of leaves (c. 60kg/tree), flowers (30 kg/tree), and pods (30 kg/tree). The existence of a significant feed resource in the fallen inflorescence was unexpected and previously unreported. In addition the tree canopy has a positive effect on grass dry matter production.
