Yellow meranti
Yellow meranti (Shorea acuminatissima)

Family: Dipterocarpaceae

Common names: Yellow meranti, Yellow seraya

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

Distribution overview: The Yellow meranti group in the Shorea genera grows in Malaysia, Indonesia, and the Philippines. The growth range of Shorea genus is rather extensive, from Sri Lanka and India on the west and throughout Burma and several countries in Southeast Asia, up to the Philippines on the east. Species concentration is highest in the forests of Borneo, Sumatra, and the Malay Peninsula.

Common uses: Balusters, Bent Parts, Building construction, Building materials, Cabinetmaking, Chairs, Chests, Construction, Decorative plywood, Desks, Dining-room furniture, Domestic flooring, Drawer sides, Excelsior, Fine furniture, Flooring, Furniture , Furniture components, Furniture squares or stock, Hatracks, Interior construction, Joinery, Kitchen cabinets, Light construction, Living-room suites, Moldings, Office furniture, Paneling , Parquet flooring, Plywood, Radio - stereo - TV cabinets, Rustic furniture, Stairworks, Stools, Stringers, Sub-flooring, Utility furniture, Wainscotting, Wardrobes

Product sources: Shorea is a major source of timber in Southeast Asia. Supplies are plentiful, especially in the form of veneers and price is typically in the low 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.

Environment profile: Data source is World Conservation Monitoring Center This species is currently classified as Vulnerable within its natural habitat in Kalimantan and the Sabah region in Malaysia
