Description
Back to top

Locally known as Keruing kesat, Dipterocarpus gracilis is distributed in Borneo and the Philippines. It can be found in mixed and upper dipterocarp forest on humus-rich clay soils, at altitudes up to 800 m. The leaves are thinly coriaceous and not concave, and the bark is reddish-brown (Soepadmo et al., 2004). This species is a large emergent tree, growing between 40 and 50 m in height (Ashton, 2004; Singh et al., 2014). The woods are used for timber (Mark et al., 2014). Within Sabah and Sarawak, this species is assessed as Near Threatened but in Peninsular Malaysia, it is only assessed as Least Concern (Chua et al. 2010). The latest conservation status for this species is Vulnerable as it is threatened by habitat loss (Ly et al., 2017).
