We also grow and harvest several other native species, including noble fir, grand fir, western red cedar, Sitka spruce, Engelmann spruce, ponderosa pine, western larch, lodgepole pine and red alder. Our timberlands in the western U.S. are proof of the core tenet of sustainable forestry, as we are now planting our third generation of trees in many locations - including more than 400,000 acres of the original land our founder purchased back in 1900. In Washington and Oregon, we reforest all our harvested sites by directly planting superior and climate-adapted tree seedlings. Our timberlands in the western United States were historically dominated by Douglas-fir, the primary species we still plant and harvest today.

This interaction of geology, topography, soils, biology and climate makes the region among the most productive conifer-growing areas in the world. The rugged terrain is the result of the continued uplift of mountains, and, as the mountains rise, they are subject to the erosive forces of weather, and those of streams and rivers that carry sediment and nutrients to the ocean. The volcanic peaks that make up the Cascade Mountains testify to a long history of eruptions that continue today, including the 1980 eruption of Mount St. Chains of volcanic islands collided with the North American continent to become portions of western Oregon and Washington. The geology of the region tells a compelling story. Our timberlands span from southern Oregon to the North Cascade Mountains in Washington, and they range in elevation from a few hundred feet to as high as 5,550 feet. The region's wet and mild climate, with most of the annual precipitation falling during the winter months, makes for incredible growing conditions. Today, we own approximately 2.6 million acres of highly productive forests in Oregon and Washington. Weyerhaeuser’s first timberlands were in the Pacific Northwest, dating back to when we purchased 900,000 acres of forestlands in Washington state in 1900.
