However, the species likely exists today in relatively large numbers. The species is globally imperiled due to its rarity ( defined by about 6 to 20 occurences within its range, few remaining species within its range, or number of species confined to a small area), or some unknown but existing factors that make it vulnerable to extinction throughout its range. Believed to be abundant in Bolivia. Distribution Overview In non-flooded forests around Manaus, Brazil. Heartwood Color Brown Red Reddish brown The heartwood is reddish- or purplish-brown, occasionally with dark streaks. Sapwood Color White Pale brown Not clearly differentiated from the heartwood. Grain Even Straight Interlocked Straight to interlocked Texture Coarse Medium Luster Medium Natural Durability Perishable Non-resistant to powder post beetles Susceptible to insect attack Non-durable Resistant to attack by dry-wood termites Heartwood which is darkly colored is generally durable. Silica Content Likely to have significant impact on machining Contains silica Some Cariniana timbers have been reported as containing silica in excess of 0.05%, above which machining properties are believed to be affected Kiln Schedules T3 - D2 (4/4); T3 - D1 (8/4) US Drying Defects Distortion Special attention required Distortion (twist/warp) is likely Air-seasoning may cause checking/warping Use care to minimize defects Ease of Drying Rapidly Medium to High Shrinkage Reconditioning Treatement Little degrade Dries fairly rapidly but requires care Tree Size Tree height is 20-30 m Product Sources The ITTO reports that timber from produced at a low but regular rate. Export potential is rated as fair. a one of about 10 species of the Cariniana genus that are collectively represented by the trade names of Albarco or Jequitiba.

It compares favorably with Teak, which also has high bending strength. Maximum crushing strength, or compression strength parallel to grain, is high. Some familiar species with high crushing strength parallel to grain include Hard maple, Teak, and White oak. Hardness is rated as medium. It resists denting and marring about as well as white oak or birch. It is a heavy wood. The density is high.
