    Description

    Timber inventory data for all owners in western Washington and western Oregon were summarized by age classes to provide an estimate of the remaining amount of old growth timber. The data suggest that roughly 30 percent of the timberlands in the Douglas-fir region contain essentially mature timber (stands whose age is in excess of culmination of mean annual increment). Available information on value of old growth is scanty but does suggest that old-growth Douglas-fir is some 56 percent more valuable than second-growth Douglas-fir.
