Agroforestry Uses:

A pioneer species, often colonizing clearings[].
The tree has been planted to stabilize slopes and to prevent soil erosion, especially in the Darjeeling Hills of India[]. It is also used in reforestation projects[].

Other Uses

The bark yields a little tannin[].

Yields a medium-weight to heavy hardwood that is moderately hard and fairly strong and elastic[]. The heartwood is deep red-brown with a purplish tinge, not clearly differentiated from the paler sapwood; grain shallowly to broadly interlocked; texture fine and even; wood with broad stripes on quarter-sawn surface due to the interlocked grain, planed surfaces lustrous. Sawing is moderately easy to easy and it is easy to plane, it finishes exceptionally well and takes a high polish. The wood is easy to peel and yields a good-quality veneer. It is slightly to moderately durable. The wood is slightly susceptible to ambrosia beetle attack, the sapwood is non-susceptible to Lyctus[].
The wood is used for light and medium heavy construction under cover (beams, scantlings, planks), joinery, furniture, millwork, flooring and interior work. In India it is also used for bridges, door and window frames, general carpentry and tea chests[]. The wood is recommended for the production of veneer and plywood[].

Propagation

The seed shows about 30% germination in 17-73 days. Seedlings develop very slowly in the nursery during the first 2 years, only reaching 10 - 25 cm in height[].
There is no difference in viability between seeds collected off the trees and those collected from the ground, provided the capsules of the latter have not yet opened[].
