Quercus gaharuensis is a species of oak native to Borneo, Sumatra, and Peninsular Malaysia.[1][2] It is placed in Quercus subgenus Cerris, section Cyclobalanopsis.[3]

Range and habitat

Quercus 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

Quercus gaharuensis is threatened with habitat loss from widepread deforestation across its range.
