Large areas of the zone, however, are dominated "by second growth and some old-growth Douglas-fir forests. Much of the subregion has been logged, or logged and burned, during the past years. Major forest species are Douglas-fir, western hemlock, western redcedar, grand fir, Sitka spruce (near the ocean), and western white pine. Prescribed understory burning is presently used on a limited basis on the West Side, but may increase in applicability as more "second growth" Douglas- fir stands are intensively managed "Old growth" Douglas-fir stands on the West Side may accumulate up to several feet of litter and duff under natural conditions. A closed-dynamic-chamber system (CDCS) was used to measure the spatial and seasonal variability of the soil CO2 efflux (Fs) in beech and in Douglas fir patches of . Old-growth forests often have complex, uneven age structures reflecting both the long time elapsed since a major disturbance and the periodic formation of small canopy gaps.
The monograph describes some distinctive biological and ecological features of our forest trees in layman’s terms (in a popular form). It gives consideration to all the tree species such as.

(4) That, assuming timber production is one of the more important objectives on a given area, clearcutting is the most desirable practice, giving full consideration to other resource values, overall environmental impacts, and economics, over much of the Douglas-fir region.
