Dipterocarpus dyeri

Dipterocarpus dyeri (Khmer: rôyiëng, chhë tiël pruhs, chhë tiël th'nô:r,[2] local name Kompong Thom: chhieutiel chgor,[3] name used for commercial timber and the group of trees harvested for such: keruing, Vietnamese: Dầu Song Nàng,[4] is a species of tree in the family Dipterocarpaceae found in Myanmar, Thailand, Peninsular Malaysia (Kedah, Perlis), Cambodia and Vietnam.[1][5] The tree is found in lowland semi-evergreen dipterocarp forests and Schima/bamboo forests,[1] an alternative habitat description is mixed dense forests of the plains, mainly among rivers and valleys.[2] The tree is a climax or late successional species, which in some secondary forests forms relatively young pure colonies.[6] The conservation status is based on rates of habitat loss, the major threat to the taxa,[1] though in Vietnam it is cited as having a less threatened conservation status of Vulnerable.[4]
