Physical and Environmental Profile

Environmental Profile
The conservation status of this species within its natural growth range has not been officially assessed.

 

Distribution
Restricted to eastern Mexico from Tamaulipas to Oaxaca; a favored plantation species in Angola, Kenya, Tanzania, South Africa, and elsewhere in Africa. Planted as well in New Zealand, Australia, India, Brazil, and Argentina.

Tree Data
Heights to 115 ft with trunk diameter of 18 to 60 in. are reported.  Boles straight and cylindrical.

Sapwood Color
one of the whitest of pines

Heartwood Color
Heartwood in plantation-grown material is not easily distinguishable from sapwood; one of the whitest of pines; growth rings are distinct.

Ease of Drying
Reports are variable; material from 30-to 40-year-old trees seasoned well with little degrade; dries rapidly. Air-drying from green (150 to 200% moisture content) to 20% required 2 to 3 weeks for 4/4 stock. Reported to kiln-dry rapidly without severe degrade. Kiln schedule similar to T13-C4S has been suggested for 4/4 stock. Shrinkage green to ovendry: radial 4.1%; tangential 7.9%; volumetric 12.6%.
