DESCRIPCIÓN DEL ÁRBOL
Descripción botánica
It is a medium-sized to fairly large tree, up to 30 m tall. The bole is up to 125 cm in diameter and branchless for up to 20 m, but often much shorter and crooked, with buttresses.
Hábitat natural
Molave is the dominant timber species in monsoon forest in the Philippines. It occurs on well-drained limestone soils. Exploitation of the highly prized timber has led to the reduction of molave forests. The species is now subject to felling controls in t
Existencia de plantaciones?
Plantations of this species are reported in Central America.
