Environmental Profile
Vulnerable in parts of its natural habitat
Status unknown in many of its growth areas
Rare in parts of its natural range
Data source is World Conservation Monitoring Center

The environmental profile of this species within its natural habitat in the Orissa State in India is classified as Rare. Its conservation category in Vietnam is Vulnerable. Its status in the wild is currently listed as unknown due to inadequate information in most areas in its range including, China, Myanmar or Burma, India, Nepal, Thailand, Malaysia, and Sri Lanka

Distribution Overview
Widely distributed in the moist tropical forests of South and Southeast Asia where it is a dominant canopy tree. In peninsular Malaysia, it occasionally occurs as a coloniser of bare lands. In the area of natural distribution it is found in the lowlands and up to 800 m altitude, in areas with 1400-4000 mm rainfall/year. Prefers annual rainfall of more than 2000 mm a year, although it tolerates as little as 850 mm but then growth is slow. It thrives in areas with uni- as well as bimodal rainfall regimes. Best growth when mean annual temperature is 20- 25°C and absolute minimum of 5-10°C. Outside its natural distribution it is grown in plantations in West and South Africa plus some Caribbean countries and Costa Rica..
