However, if underused or poorly managed, it can be a source of headache to farmers and the country as a whole. Acacia leucocephala (Lam.) [17], Leucaena leucocephala has been considered for biomass production because its reported yield of foliage corresponds to a dried mass of 2,00020,000 kg/ha/year, and that of wood 3040 m/ha/year, with up to twice those amounts in favorable climates. Leucaena leucocephala is a small fast-growing mimosoid tree native to southern Mexico and northern Central America (Belize and Guatemala)[1][3] and is now naturalized throughout the tropics including parts of Asia.
