Dipterocarpus retusus, commonly known as hollong, is a large tree and perhaps the best known species in the genus Dipterocarpus. It is native to China, Vietnam, Philippines, Laos, Cambodia, Malaysia, Indonesia, Myanmar, and India. The tree, some 20–30 metres (70–100 ft) tall, is found in Cambodia in dense forests of the plains, common on hillsides and along rivers and in forests between 800 m (2,600 ft) and 1,500 m (5,000 ft) altitude.
Dipterocarpus is a genus of flowering plants and the type genus of family Dipterocarpaceae.

It is native to peninsular Thailand and Malaysia and also Borneo, where it is locally known as keruing merkah or keruing beludu. It is an emergent tree up to 60 m tall. The tree occurs in mixed dipterocarp forests found on sandy and sandy clay soils on coastal hills and inland ridges, up to 1000 m altitude. It occurs in at least one protected area.
Dipterocarpus caudiferus is a species of tree in the family Dipterocarpaceae, endemic to Borneo. It grows as a large tree, up to 65 metres (200 ft) in height. Its habitat is mixed dipterocarp forests at altitudes up to 800 m (2,600 ft). Dipterocarpus caudiferus is threatened mainly by conversion of land for palm oil plantations.

Danum Valley Conservation Area is a 438 square kilometres tract of relatively undisturbed lowland dipterocarp forest in Sabah, Malaysia. It has an extensive diversity of tropical flora and fauna, including such species as the rare Bornean orangutans, gibbons, mousedeer, clouded leopards and over 270 bird species. Activities offered are jungle treks, river swimming, bird watching, night jungle tours and excursions to nearby logging sites and timber mills.
Dipterocarpus grandiflorus is a species of flowering plant in the Dipterocarpaceae family. It is an endangered medium hardwood tree in South-East Asia and India. Its wood is used to produce good quality charcoal, paper pulp, and timber sold under the Keruing designation. Its gum is used locally as a waterproofing varnish. The tree itself is very useful for nitrogen fixing, erosion control, soil improvement, and watershed regulation.
The lesser large-footed bat is a species of vesper bat. It can be found in Cambodia, India, Indonesia, Malaysia, Myanmar, Sri Lanka, Thailand, and Vietnam.
Shorea obtusa, the Siamese sal, is a species of hardwood tree in the family Dipterocarpaceae, native to Southeast Asia.
Dipterocarpus alatus, also known colloquially as the resin tree, is a tropical forest tree, of dense evergreen or mixed dense forests, in tropical Asia. It is considered vulnerable. It often occurs gregariously along river banks and is a key planting species for regenerating deforested land around the Dong Nai river and Cat Tien National Park.
Dipterocarpus tuberculatus is a species of tree in the family Dipterocarpaceae found in Bangladesh, Myanmar, Thailand, Cambodia, Laos and Vietnam. The tree is found in clear forests of plains, at altitudes up to 800-1000m. It grows to a height of 5–25 m.
Dipterocarpus costatus is a species of tree in the family Dipterocarpaceae found in the Indochinese and Malay Peninsulas, including Cambodia. The tree is found in "mixed dense deciduous or half-deciduous forest of the plain and in wet dense altitude forest, up to 1200 m, on well drained rich grounds." It grows to a height of 25-40m. In Cambodia the resin is used particularly for the caulking of boats, and the preparation of torches, the wood used for work not exposed to the elements.
Dipterocarpus dyeri (Khmer: rôyiëng, chhë tiël pruhs, chhë tiël th'nô:r, local name Kompong Thom: chhieutiel chgor, name used for commercial timber and the group of trees harvested for such: keruing, Vietnamese: Dầu Song Nàng, is a species of tree in the family Dipterocarpaceae found in Myanmar, Thailand, Peninsular Malaysia, Cambodia and Vietnam. The tree is found in rain forest and lowland semi-evergreen dipterocarp forests, an alternative habitat description is mixed dense forests of the plains, mainly among rivers and valleys. The tree is a climax or late successional species, which in some secondary forests forms relatively young pure colonies. The conservation status is based on rates of habitat loss, the major threat to the taxa, though in Vietnam it is cited as having a less threatened conservation status of Vulnerable.
Dipterocarpus intricatus is a species of tree in the family Dipterocarpaceae found in Thailand, Cambodia, Laos and Vietnam.
Dipterocarpus obtusifolius is a common species of tree in the family Dipterocarpaceae found throughout Southeast Asia, including Andaman Islands, Myanmar, Thailand, Cambodia, Laos and Vietnam.
