Distribution Overview
The geographical range of the species, which is a member of the Yellow meranti group of Shorea includes Malaysia, Indonesia, and the Philippines. The genus is widely distributed, from India and Sri Lanka in the west and extending throughout Burma and several countries in Southeast Asia, up to the Philippines in the east. Highest concentrations of Shorea species are reported to occur in Borneo, Sumatra, and the Malay Peninsula.

Product Sources
Species in the Shorea group are a major source of timber in international trade. They are plentiful, and supplies are universally available, especially in the form of veneers. This popular wood is typically priced in the inexpensive range.
Many species in the Shorea genus are also a source of other economically important non-timber products. Seeds of some species yield fat which is used in the manufacture of chocolate. Others produce nuts, the most common of which is the illipe nuts of commerce produced by S. gysbertisiana . The nuts yield a fat which is similar to cocoa-butter in some of its properties. Shorea trees are also tapped for oleo-resin, and typical dammar is obtained from S. wiesneri which grows in Java and Sumatra. The tree of S. robusta produces dammar which is used as a disinfectant and as incense in religious ceremonies in India. Other non-timber products from Shorea are reported to include tannin and fibers.
