Pinus ponderosa, commonly known as the ponderosa pine, is a large coniferous tree native to western North America. It typically grows in mountainous regions and can reach heights of 100 to 200 feet. The tree is characterized by its long, straight trunk and thick, yellow-brown bark that develops deep fissures as it matures. The needles of the ponderosa pine are long, usually in bundles of three, and can grow up to 10 inches in length. This species produces large, woody cones that can be 3 to 6 inches long. Pinus ponderosa is valued for its timber, which is used in construction and furniture making.
