Description
The Douglas Fir is one of the world’s most important and valuable timber trees. The native range of this species is the greatest of any commerical conifer of western North America, stretching from Vancouver Island and interior British Columbia at its northern limit, along the Rocky Mountains west to Montana and Wyoming, east to the coasts of Washington and northern California, and south to Colorado, Nevada and Utah. Found on a variety of soils, but grows best on deep. well-drained, sandy loams where moisture in the soil is abundant. Its exceptionally strong lumber is often used for structural purposes, interior and exterior finishes, and railway ties. It is also prized as a Christmas tree when grown in its native range.
