Distributed in: Indonesia, Malaysia, Philippines, Thailand (Oceania and S.E. Asia)

Distribution overview: The geographical range of S. leprosula which belongs to the Light red meranti group includes the Malay Peninsula, Indonesia, the Philippines, as well as Sabah and Sarawak. reported to grow at low altitudes and prefers well-drained soils.

Common uses: Beams, Bedroom suites, Building construction, Cabin construction, Cabinetmaking, Chairs, Chests, Concealed parts (Furniture), Concrete formwork, Construction, Decks, Decorative plywood, Desks, Dining-room furniture, Domestic flooring, Dowell pins, Dowells, Drawer sides, Excelsior, Factory construction, Factory flooring, Fine furniture, Floor lamps, Flooring, Form work, Foundation posts, Framing, Furniture , Furniture components, Furniture squares or stock, Hatracks, Heavy construction, Joinery, Joists, Kitchen cabinets, Light construction, Living-room suites, Office furniture, Parquet flooring, Plywood, Porch columns

Product sources: Shorea genus is a major timber source 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 genera 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.
