The ponderosa pine (Pinus ponderosa) is a large coniferous tree native to western North America. It typically grows in mountainous regions and can reach heights of 100 feet or more. The tree is known for its distinctive yellow-brown bark, which becomes thick and deeply furrowed as it matures. Its long, slender needles grow in bundles of three and can be up to 10 inches long. Ponderosa pines thrive in a variety of soil types and are often found in dry, open forests. They are important for wildlife, providing habitat and food for various species. The wood of the ponderosa pine is valued for its strength and is commonly used in construction and furniture making.
