Pine is pine, right? Not quite. There’s quite a range in density and strength when it comes to the Pinus genus. Take one of the species of southern yellow pine, Shortleaf Pine, for instance: it has strength properties that are roughly equivalent to Red Oak (with the notable exception of hardness)—and in some categories, such as compression strength parallel to the grain, the pine is actually stronger!
This grouping can be thought of as an intermediate position between the soft pines and the hard pines. Unlike southern yellow pines, this group doesn’t quite fit the bill of the usual characteristics of hard pines. Although the included species have relatively abrupt earlywood to latewood transitions, they tend to be lighter in weight, (average dried weights range from 28 to 29 lbs/ft3), and have a more even grain appearance. The two main species in this grouping are so similar in working characteristics that they are sold and marketed interchangeably. Construction lumber from this group is stamped with the initials PP-LP, representing the two species of western yellow pine:
Although these two woods are difficult to distinguish from an anatomical standpoint, (Ponderosa Pine tends to have slightly larger resin canals), they can sometimes be separated by viewing the wood on a larger scale.
Ponderosa Pine trees typically have larger trunk diameters than Lodgepole Pine (two to four feet for Ponderosa versus one to two feet for Lodgepole). Accordingly, the wood of Ponderosa Pine usually furnishes wider, more knot-free wood, and has broader arcs in the growth rings when compared to Lodgepole Pine.
