Levels of exploitation are very high. Little regeneration takes place after disturbance. Individuals reach a seed-producing age at 30 years, although large seed crops appear only at three to four year intervals. The tree is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2010)[

Other Uses

The heartwood is a pale reddish-brown; it is more or less demarcated from the 3 - 8cm wide band of yellowish-brown sapwood. The texture is medium; the grain interlocked. The wood is light in weight; soft; fairly durable, being resistant to dry wood borers, moderately resistant to fungi but susceptible to termites. It seasons rapidly with only a slight risk of checking or distortion; once dry it is moderately stable in service. The wood is easy to work with ordinary tools; there is a tendency to woolliness so the tools need to be kept very sharp; care needs to be taken when planing due to the interlocked grain which can cause tearing; nailing and screwing are good; gluing is correct. A high quality timber, it is used above all for high-quality cabinet work, furniture and expensive interior finishing. Large quantities are also used for boat and ship construction[
