Fall Creek second-growth Douglas-fir thinning study.

Abstract

As the supply of old-growth timber in the Douglas-fir region decreases, there will be a continuous increase in the use of second growth. Eventually the entire wood-using industry will be wholly dependent on the younger timber stands, The exact amount of second growth being cut at present is not known, but it is estimated that close to one-third of the lumber production in the Douglas-fir region came from timber less than 160 years old, or what are commonly known as second-growth stands. The acreage of these young timber stands is sizeable. Recent surrey figures show second-growth forests, plus recently cut-over lands, amount to approximately two-thirds of the commercial forest land in the Douglas-fir region.
