Physical and Environmental Profile
A variety of this species found in Cuba, P. caribaea var. caribaea, is currently classified as Rare. Another variety, P. caribaea var. bahamensis, has also been classified as Rare in the Bahamas (Source - World Conservation Monitoring Center - 1992).
The species is reported to naturally occur in the Bahama Islands, western Cuba, Honduras, Guatemala, and Nicaragua, but it has been established successfully in Queensland, Western Australia, Fiji, Sri Lanka, South Africa, and elsewhere. In South Africa, the species is reported to be confined to the heavy rainfall areas of the Eastern Transvaal, Zululand, and the Cape Midlands. Until recently, Slash pine (P. elliottii) from southeastern United States is reported to have been known as Pinus caribaea.
It is currently unknown whether some material from this species is available from sustain ably managed, salvaged, recycled, or other environmentally responsible sources.
The tree is reported to attain a height of about 100 feet (30 m), with a trunk diameter of 30 to 40 inches (75 to 100 cm), sometimes larger. It develops boles with a moderate taper, that are about 70 feet (21 m) long.
The sapwood is easily distinguishable, and is lighter in color than the heartwood.
The color of the heartwood is generally golden brown to red brown. Resin canals are reported to be numerous.
The grain is usually straight.
The texture is described as somewhat coarse.
The wood has medium luster.
The wood imparts a strong resinous odor.
Ease of Drying
The timber is reported to air-season rather slowly, with very little degrade.
Timber in thicker sizes may end-split, and low-density plantation wood may warp slightly during drying.
T10 - D4S (4/4); T8 - D3S (8/4) US
T/R Ratio - 1.33
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).
Performance against attack by decay fungi is reported to be determined by the amount of resin in the wood. Heartwood resistance is rated as generally moderate, and could last from 10 to 15 years in contact with the ground without any chemical protection. The sapwood is prone to blue stain.
Resistance to Impregnation
The heartwood is reported to have moderate response to preservative penetration, but the sapwood is reported to be highly permeable.
Abnormal Wood Tissue
Compression wood is reported to be common.
The wood has low resistance to sawing although cutters may be gummed up because of high resin content.
Planing properties are reported to be generally good.
The wood turns well, but resin may gum up cutters.
Moulding characteristics are reported to be generally good.
The material is reported to respond well to boring.
Routing & Recessing
Routing qualities are reported to be generally good.
The wood is reported to respond well to ordinary tools in mortising.
The material has good carving properties.
The timber is reported to have satisfactory gluing properties.
The wood is reported to take nails well.
Screwing properties are rated as good.
Sanding qualities are reported to be generally good.
Response to Hand Tools
The wood responds well to hand tools.
The species has high bending strength in the air-dry condition (about 12 percent moisture content). Maximum crushing strength, or compression parallel to grain in the air-dry condition, is also in the high range. It is fairly hard, resisting wear, denting, and marring fairly well. The wood is heavy and dense.
