Common Rengas

<em>Gluta wallichii</em>, the common rengas, is a tropical tree in the family Anacardiaceae, order Sapindales, related to mangoes, cashews, and poison ivy. The species is assessed as Least Concern on the IUCN Red List. Rengas trees typically inhabit lowland and hill dipterocarp forests, as well as peat swamp and freshwater swamp forests across Southeast Asia, particularly in the Malay Peninsula and Borneo. The wood of <em>Gluta wallichii</em> is valued commercially for timber, though the sap contains urushiol-like compounds that can cause severe dermatitis in sensitive individuals, a trait shared with other members of the Anacardiaceae family. The genus Gluta is known for large, canopy-forming trees that typically reach substantial heights in undisturbed rainforest settings. As a flowering angiosperm, rengas produces fruit that serves as food for forest birds and mammals including hornbills and civets, contributing to seed dispersal. Biological traits such as lifespan, body measurements, and detailed diet ecology remain poorly documented for this taxon in published literature. Threats to this species include deforestation, logging, and conversion of peat swamp forests for agriculture, particularly oil palm cultivation, across its Southeast Asian range.
