Northwest Conifers

Pines – Pinus

Although pines are the most common conifer throughout the world, they don't compete as well in the climate of the Northwest, where forests are dark, damp, and dense. You will find them high in the mountains in more open forests and east of the Cascades where the weather is dry. Pines have long needles that grow in bundles. You can usually identify a pine by the number of needles in each bundle. The cones are the largest you will find in the Northwest. Unlike the thin scales on hemlock and spruce cones, pine cones have thick, woody scales. Pinus, of course, means "pine tree." Four species of pine grow throughout the mountains of the Northwest.
