It is especially abundant in the humid coastal lowlands and in other humid areas. To identify and enhance Leucaena tree suitability as particleboard resource a two- prong study was done. As for particleboard manufacturing, Leucaena: Rubberwood admixture bound with urea formaldehyde (8%, 10%, and 12% resin content) to a density of 700 kg/m3, showed promise of usability when all boards pass the Type P2 board requirement of EN312:2010. This species has potential as an alternative resource for the Malaysian furniture and panel board industries in the coming years because of a shortage of the current frequently used raw material (rubberwood). 0000000679 00000 n Traces of 5MeO-DMT has been found in maidenii wood (October 1995).

Leucaena, Jumpy-bean, jumbay, white leadtree, river tamarind, ipil-ipil. It was observed that with a planting distance of 3 m 3 m, the Leucaena trees planted in the field sagged and grew according to the wind direction, which indicated that young Leucaena trees need to be supported until they are larger in size. In such cases, toxicity problems from ingestion of Leucaena have sometimes been overcome by infusing susceptible animals with rumen fluid from ruminants that possess such organisms,[15] and more recently by inoculating cattle rumina with such organisms cultured in vitro. de Wit white leadtree", "Leucaena leucocephala - Hong Kong Flora and Vegetation", "Activists want Pune Municipal Corporation to allow cutting of subabul trees in city", "Allelopathic research of subtropical vegetation in Taiwan".

This activity was undertaken as part of the BioNET-EAFRINET UVIMA Project (Taxonomy for Development in East Africa). Recently, the wood part of the Subabul tree is used for making pulp in the pulp and paper industry. It has even been suggested that the leaves decompose too rapidly, resulting in leaching of nutrients away from the crop-rooting zone before they are taken up by the crop. Forms dense thickets and displaces the native vegetation in disturbed areas, coastal strands, forest edges and canopy gaps. Leucaena leucocephala is considered one of the 100 worst invasive species by the Invasive Species Specialist Group of the IUCN Species Survival Commission. iucngisd.org. Kasim, J.
