Data source is World Conservation Monitoring Center Its status in the wild is currently listed as unknown because of insufficient information in Papua New Guinea and Indonesia Distribution Overview Native to the Philippines and other western Pacific islands, including Australia and New Guinea. Favored as a plantation species throughout the world in lowland humid tropics. Heartwood Color Red Reddish brown Pale red to pink Pale brown Red Brown Yellow to golden-yellow to orange Light red Light brown Dark brown Sapwood Color White to yellow Pinkish Color not distinct from heartwood Whitish Well defined Paler than heartwood Grain Interlocked Straight Rippled (figure) Figure Even Texture Medium Medium to coarse Coarse Medium Luster Lustrous Slightly lustrous Natural Growth Defects Brittleheart is often frequent and extensive Natural Durability Very durable Moderately durable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Non durable Susceptible to attack from termites (Isoptera) Resistant to attack from powder post (Lyctid & Bostrychid) beetles Susceptible to marine borer attack Sapwood is susceptible to wood staining fungal attack Vulnerable to attack by powder-post beetles Pinworm (ambrosia beetle) often present in the heartwood Perishable Moderately resistant to termite (Isoptera) attack Heartwood susceptible to attack by decay fungi and insects. Durable Odor No specific smell or taste Kiln Schedules Drying (speed) is fast Kiln Drying Rate (in days) is fairly rapid Dry at a slow speed Dry at a moderate speed Drying Defects Moderate collapse and honeycombing Slight twist/warp Slight collapse and honeycomb Moderate surface checking Slight surface checking Moderate twist/warp Moderate end spitting 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. Ease of Drying Moderate Difficult Plantation grown wood is easier to dry than forest-grown material. Backsawn material is also difficult to kiln dry. Kiln Drying Rate Fairly rapid (11-17 days for boards under 32 mm, to 31-51 days for boards greater than 63 mm) Tree Identification Bole/stem form is straight Bole/stem form is cylindrical Bole/stem form is not buttressed Product Sources Comments General finishing qualities are rated as good Blunting Effect Slight effect Blunting effect on sawing green wood is moderate Blunting effect on machining is moderate Boring Easy Cutting Resistance Cutting Resistance with green wood is easy Cutting Resistance with dry wood is easy Good sawing properties Cutting Resistance with green wood is moderate Cutting Resistance with green wood is difficult Cutting Resistance with dry wood is moderate Cutting Resistance with dry wood is difficult Gluing Easy to glue Good properties Mortising Finishes well Finishes satisfactorily Moulding Satisfactory moulding results Movement in Service Small Medium Nailing Possible if prebored Holds nails well Good nailing properties Easy to nail Planing Planes to a satisfactory finish Easy to plane Ease of planing is moderate Planes well, to a good finish Resistance to Impregnation Sapwood is permeable Heartwood is resistant Heartwood is highly resistant Heartwood is moderately resistant Resistance to Splitting Poor Response to Hand Tools Easy to machine Moderate working qualities Sanding Good sanding finish Very good characteristics Easy to sand Screwing Screwing yields good results Turning Poor results Veneering Qualities No steaming needed during bolt preparation.
