Ponderosa Pine (Pinus ponderosa) 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.
Pinus ponderosa, commonly known as the ponderosa pine, [3] bull pine, blackjack pine, [4] western yellow-pine, [5] or filipinus pine, [6] is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America. [7]: 4.
Mature Ponderosa Pines are easily identified by their distinctive orange-brown bark, arranged in large plates. Trees average 30 to 49 metres in height, with some exceeding 60 metres; diameter ranges from .6 to 2.4 metres. The dark, yellow-green needles are 127 mm to 254 mm long and grow in clusters of three.
Ponderosa Pine has a minimal amount of of reddish-brown heartwood and exceptionally wide sapwood which is honey-toned or straw-like in color. It has a straight, uniform grain which machines to a clear smooth surface.
Old-growth ponderosa pine produces clear, knot-free, high grade lumber, but young trees are often limby because self-pruning develops slowly, causing knotty lumber. The mature tree's uniform grain makes it desirable when appearance rather than strength is important.
Ponderosa pine, the largest of the western pine species, is found on semi-arid plateaus and slopes in B.C.’s southern interior. The wood is straight-grained, nonporous with a fine and uniform texture, and light in colour, ranging from cream to yellow to pale reddish-brown.
