Ipil (Tree)
Also known as: Intsia bijuga (scientific name) · Merbau (international timber name) · Kwila (trade name in Oceania)
Definition
The ipil (Intsia bijuga) is a large tropical hardwood tree of coastal and lowland forests in the Philippines and the wider Indo-Pacific, yielding one of the region’s most durable timbers, known in international trade as merbau or kwila. Valued for construction, boatbuilding, and carving, the species is now considered threatened by overharvesting across its range.

Examples and Analogies
In Philippine traditional construction, ipil played the role that teak played in mainland Southeast Asia: the premium, salt-resistant wood chosen for house posts, hulls, and joining exposed to moisture, where lesser timbers would rot within years.
Usage Scenarios
Historically cut for house posts, church beams, ships, and tool handles, ipil wood today appears in fine flooring and furniture where legally available; living trees serve as coastal shade and are planted in reforestation and urban greening projects.
Strategies
Conservation strategies combine harvest regulation, plantation establishment, and certification schemes for merbau timber, while wood identification technologies help customs agencies interdict illegally logged shipments in international trade.
Security and Safety Measures
The species is protected by national logging regulations and international monitoring; enforcement focuses on illegal cutting in remaining coastal forests and on trade documentation, since untraceable merbau has financed deforestation in several countries.
Historical Context
Ipil was among the prized timbers extracted during the Spanish and American colonial timber booms, and its depletion in accessible coastal forests across the twentieth century mirrored the broader erosion of the Philippines’ premium hardwoods, from narra to lauan.
Challenges and Controversies
Illegal logging and land conversion continue to reduce stands, and contested forestry permits, disputed indigenous land claims in some coastal ranges, and debates over plantation-versus-protection approaches keep ipil’s management politically charged.
