Agroforestry Uses:

The tree is planted as a pioneer species in northern Thailand in reforestation projects to restore native woodland - it is planted in degraded woodland and open areas in a mix with various other species that all have the ability to grow fast; produce dense, weed-suppressing crowns; and attract seed-dispersing wildlife, particularly birds and bats[].

Other Uses

The wood is rather heavy and dense. It is not highly appreciated[]. It is used for house building under cover, interior finish, furniture, packing cases and tea boxes, and for the production of veneer and plywood. It is suitable for the production of wood-wool board[].
