AMERICAN SOUTHERN YELLOW PINE
V. Ryan © 2008
|A much under utilised softwood.
Made up of four botanical species:
Shortleaf Pine - Pinus echinata
Longleaf Pine - Pinus palustris
Loblolly Pine - Pinus taeda
Slash Pine - Pinus elliotti
Commercial names: Carolina Pine. Must not be confused with Quebec Yellow/White Pine (Pinus strobus) which originates from Eastern Canada and North Eastern USA.
Distribution: The species grows on an area of 78 million hectares of forest-land in Southern USA; Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North and South Carolina, Oklahoma, Tennessee, Texas and Virginia.
General Description: The heartwood is orange to
reddish-brown in colour and may be resinous. The growth rings are clearly
marked by the contrast between the earlywood and darker, more dense
latewood giving a coarse texture, especially in rapidly grown timber.
Southern Yellow Pine sheds its branches as it grows with the crown
generally consisting of the upper one-third of the tree. As a result,
knots are intergrown and sound with few holes or dead knots in the timber.
Since, with increasing frequency the trees are grown and harvested on
short rotation, saw-logs are comparatively small with sapwood
predominating. The weight varies between 537 and 626 kg/m3 (34 -
39lb/ft3); specific gravity 0.54 to 0.63.
