Douglas-fir is not a true fir at all, nor a pine or spruce. It is a distinct species named after its discoverer Archibald Menzies and a botanist, David Douglas. A major characteristic that distinguishes it from true firs is its cone which falls from the tree intact. Douglas-fir is.

Interior Douglas-fir is a prevalent forest type throughout the central Rocky Mountains. Past management actions, specifically fire suppression, have led to an expansion of this forest type.

Although Douglas-fir forests cover a broad geographic range, few studies have described the interactive effects of various disturbance agents on forest health by: 4.

GENETICS OF DOUGLAS -FIR Roy R. Silen 1 INTRODUCTION In the natural forest, Douglas -fir (Pseudot- suga menziesii iMirb.] Franco) is a remark- ably successful species. It vies with coastal redwood for height supremacy among the world's the droughty, fire -prone natural environment of Western North Amer- ica, it has dominated the better sites, often.

The coast Douglas-fir variety is the dominant tree west of the Cascade Mountains in the Pacific Northwest, occurring in nearly all forest types, competes well on most parent materials, aspects, and slopes. Adapted to a moist, mild climate, it grows larger and faster than Rocky Mountain : Tracheophytes.

of Douglas-fir in old-growth compared with young stands. In typical, closely spaced young stands, Douglas-fir generally have short crowns with structurally simple live branches confined to the upper one-third to one-quarter of the bole. Franklin et al.
