Douglas Fir

West of the Cascade Mountains, Douglas fir dominates the forested landscapes often accounting for 90% or more of the trees in an area. Disturbance in the form of wildfires, volcanic eruptions, earthquakes and landslides have perpetuated these forests in Douglas fir for centuries. Today, foresters mimic the cycles of natural disturbance and renewal, managing commercial timberlands primarily in natural stands on long rotations for a variety of forest values.
