Meranti-gerutu (Parashorea lucida)
Family: Dipterocarpaceae
Common names: Chengal tiga banir, Damar, Damar cirik ayam, Gerutu, Gerutu gerutu, Icap, Katuko, Lemsa meluit, Meluit, Meranti gerutu, Meranti hitam, Meranti putih, Meranti-gerutu, Red meranti, Surantih, Tambun ranggas, Tengkawang pasir, Timbalon
Distributed in: Brunei, Indonesia, Malaysia, Myanmar (Oceania and S.E. Asia)
Distribution overview: This species is one of three in the Parashorea genus that are reported to occur in the Malay Peninsula. The other two are P. densiflora and P. globosa . Their distribution is restricted and they are comparatively rare.
Common uses: Boat building (general), Boat building, Boat building: framing, Boxes and crates, Bridge construction, Cabinetmaking, Construction, Flooring, Furniture, Heavy construction, Joinery, Light construction, Paneling, Particleboard, Plywood, Poles, Pulp/Paper products, Railroad ties, Vehicle parts, Veneer
Product sources: It is considered to be of little or no economic importance as a source of timber because of its scarcity.
Environment profile: Data source is World Conservation Monitoring Center
This species is Vulnerable within its natural growth range and may move into the Endangered classification if current trends persist. These trends include decreasing population due to over-exploitation, extensive destruction of natural habitat, uncertain future security due to severe depletion, and threat from serious adverse environmental factors currently existing in growth range and which has the potential to drastically reduce species population

Mechanical properties of material from Burma and Malaysia are very similar, but timber from Borneo is rated as inferior in all strength properties. The strength properties of Meranti-gerutu are intermediate between those of heavy Red meranti and White meranti
