Range and habitat
editQuercus gaharuensis is known from widely scattered sites in Sumatra, Peninsular Malaysia, and Borneo (East Kalimantan, Sarawak, and Sabah).[1]
It grows in lowland mixed dipterocarp rain forests and lower montane rain forests up to 1,400 metres elevation.[1]
Conservation
editQuercus gaharuensis is threatened with habitat loss from widespread deforestation across its range. The populations in northern Sumatra, comprising 25% of the species' known sites, are in or adjacent to protected areas. The known sites in central Sumatra and on Borneo are unprotected and have been logged or converted to agriculture.[1]
