Pinus taeda, commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from East Texas to Florida, and north to southern New Jersey. [2] The wood industry classifies the species as a southern yellow pine . [ 3 ]
Pinus elliottii, commonly known as slash pine, [2] [3] is a conifer tree native to the Southeastern United States. Slash pine is named after the "slashes" – swampy ground overgrown with trees and bushes – that constitute its habitat. Other common names include swamp pine, yellow slash pine, and southern Florida pine. [3]
Jeffrey pine wood and ponderosa pine wood are sold together as yellow pine. [6] Both kinds of wood are hard (with a Janka hardness of 550 lbf (2,400 N)), but the western yellow pine wood is less dense than southern yellow pine wood (28 lb/cu ft (0.45 g/cm 3 ) versus 35 lb/cu ft (0.56 g/cm 3 ) for shortleaf pine).

There is a strong relationship between the properties of wood and the properties of the particular tree that yielded it, at least for certain species. For example, in loblolly pine, wind exposure and stem position greatly affect the hardness of wood, as well as compression wood content. [30] The density of wood varies with species.
Pine: Pinus spp. Pine wood is hard and tough except white pine which is soft. It decays easily if it comes into contact with soil. It is heavy and coarse grained. It is used for pattern making, frames for doors and windows, and for paving material. White pine is light and straight grained and is used in the manufacture of matches. Red cedar ...
For example, balsa wood, which is a hardwood, is softer than most softwoods, whereas the longleaf pine, Douglas fir, and yew softwoods are much harder than several hardwoods. [ citation needed ] Several specific natural, macroscopic and microscopic features of wood are used in the identification process of a softwood species.
Spruce-pine-fir (SPF) is a classification of lumber that can be traded on commodities exchanges. In Canada , and parts of the United States , most of the spruce tree species , pine tree species , and fir tree species share similar physical and mechanical characteristics, to the point where lumber derived from any of these species are ...
