Physical and Environmental Profile
The environmental status of this species within its natural habitat has not been officially assessed.
Loblolly pine is reported to be native to fifteen southeastern states in the United States. Its range is reported to extend from southern New Jersey south to central Florida, west to eastern Texas, and north to the far southeastern region of Oklahoma. It grows on various soil types, from deep, poorly drained flood plains to well-drained slopes of rolling, hilly uplands, and it often forms pure stands, usually on abandoned farmlands. It is reported to grow from sea level to an elevation of 1500 to 2000 feet (457 to 610 m).
It is currently unknown whether timber from this species is available from sustainably managed or other environmentally responsible sources.
The primary commercial southern pine, Lololly pine is reported to be among the fastest growing of the southern pines, and is widely planted in forest plantations for pulpwood and lumber.
The following species in the database is reported to be as dense and as strong as Loblolly pine:
Parana pine (Araucaria angustifolia)
Loblolly pine is described as a large, resinous, and fragrant tree. It usually matures to a height of about 80 to 100 feet (24 to 30 m) and a diameter of about 24 to 36 inches (60 to 90 cm).
The wood is initially pink brown, and matures to a slightly darker color upon exposure. Sapwood is not distinct from the heartwood.
Grain is described as closed, with high figuring, and pattern ranges from clear to knotty.
The texture is fine and even.
There is no distinct odor or taste.
Ease of Drying
The material is reported to dry, but conditions should be controlled to prevent excessive degrade.
There is a tendency for the timber to distort and check during drying.
T/R Ratio - 1.40
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).
Heartwood resistance to decay is reported to be moderate. The sapwood is reported to be vulnerable to powder-post beetle attack and is prone to stain.
Resistance to Impregnation
The heartwood is reported to be difficult to penetrate with preservatives, but the sapwood is treatable.
The timber is reported to work fairly well but some material may pick up during planing. A reduced cutting angle is recommended.
The timber is reported to work easily in turning and most machining operations.
Moulding operations are reported to be generally easy.
The material is reported to respond well to boring.
Routing & Recessing
Routing operations are reported to be relatively easy.
Mortising characteristics are reported to be good.
Carving characteristics are rated as generally good.
Gluing characteristics are reported to be good.
The timber is reported to have good nailing and nail-holding qualities.
Screwing and screw-holding characteristics are reported to be good.
Frequent sandpaper changes are recommended since resin in the wood tends to clog up sanding materials.
Polishing properties are rated as good.
Bending strength and crushing strength of air-dried wood are fairly high. The wood is soft, and surfaces may dent easily. It is heavy and dense.
Loblolly pine, like all the other Southern pines, is reported to have many characteristics that are similar to Douglas-fir. Wood produced by old-growth Southern pine trees is reported to be generally higher in density and more stable.
