Environmental Profile
This species is reported to be secure in most areas within its natural habitat, including the Philippines. Its status in the wild is currently listed as unknown because of insufficient information in Papua New Guinea and Indonesia (Source - World Conservation Monitoring Center - 1992 ).
Distribution
The species is reported to be native to the Philippines and other western Pacific islands, and occurs in dense stands along rivers. It is reported to be one of the fastest growing hardwoods, and is cultivated widely as a plantation tree in lowland humid areas in the tropics.
Product Sources
Some material from this species is reported to be available from environmentally responsible or sustainably managed sources.
Tree Data
Kamerere trees are reported to be among the largest and tallest trees in the Philippines, attaining heights of 200 feet (60 m) or more, with trunk diameters of up to 80 inches (200 cm). Boles are often straight, and are reported to be free of branches to about 100 feet (30 m).
Sapwood Color
The sapwood is white or pinkish in color, and is not clearly defined.
Heartwood Color
The color of the heartwood is reported to vary from light red, light brown, to dark red brown. The wood is reported to be similar in appearance to Karri (E. diversicolor ).
Grain
The grain may be straight, but it is usually interlocked. A pronounced ribbon figure is reported to be present on quarter sawn surfaces.
Texture
The texture is medium to coarse.
Luster
The surface of the wood is lustrous.
Odor
There is no characteristic odor or taste.
Ease of Drying
Plantation grown wood is reported to be easier to dry than forest-grown material. Backsawn material is also reported to be difficult to kiln dry.
Drying Defects
Timber from plantation grown trees are reported to dry with little degrade, but forest-grown wood has a tendency to collapse and is prone to honeycomb during drying.
Kiln Schedules
T6 - D2 (4/4) US
T/R Ratio
2.00
This indicator is more meaningful if it is used together with other drying information and actual shrinkage data in the tangential and radial directions. (Refer to the Numerical Values window).
Natural Durability
The heartwood is reported to be susceptible to attack by decay fungi and insects. The sapwood is vulnerable to attack by the powder post beetle.
Resistance to Impregnation
The heartwood is reported to respond poorly to preservative treatment, but the sapwood is permeable.
Blunting Effect
Blunting effect on cutters is rated as slight.
Cutting Resistance
Sawing properties are reported to be good.
Planing
Although the timber is described as moderately tough and hard, material from plantation and forest grown trees are reported to work easily in all machining operations including, planing, boring, turning, mortising, and sanding. It responds readily to most ordinary tools but quartersawn stock is reported to be difficult to dress to a smooth finish.
Gluing
Gluing properties are reported to be good.
Nailing
The timber is reported to have good nailing properties.
Sanding
The timber is reported to have good sanding characteristics.
Polishing
The timbers is reported to generally finish and polish very well.
Staining
Staining properties are reported to be good.
Painting
Painting properties are reported to be good.
