Color/Appearance: Heartwood is reddish brown, sapwood is yellowish white.
Grain/Texture: Straight grained with medium texture.
Endgrain: Medium-large resin canals, numerous and evenly distributed, mostly solitary; earlywood to latewood transition fairly abrupt, color contrast can vary depending on growth ring spacing; tracheid diameter medium-large.
Rot Resistance: The heartwood is rated as moderate to low in decay resistance.
Workability: Ponderosa pine works well with both hand and machine tools. Glues and finishes well.
Odor: Ponderosa Pine has a faint, resinous odor while being worked.
Allergies/Toxicity: Working with pine has been reported to cause allergic skin reactions and/or asthma-like symptoms in some people. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Ponderosa Pine has a very wide distribution throughout western North America, and is one of the most important lumber species in the western United States. It should be widely available as construction lumber for a modest price. Some Ponderosa Pine is mixed with Lodgepole Pine and sold together as construction lumber under the stamp “PP/LP”.
Sustainability: This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern.
Common Uses: Veneer, plywood, sheathing, subflooring, boxes, crates, posts/poles, interior trim, cabinetry, and construction lumber.
Comments: Although Ponderosa Pine is technically classified as a yellow (hard) pine, it shares many characteristics with white (soft) pines, having a considerably lower density than the yellow pine species found in the eastern United States.
The city of Flagstaff, Arizona was named for a flagpole made of Ponderosa Pine that was used to raise a United States flag (then 37 stars) during a centennial ceremony on July 4, 1876.
