Abstract

The impressive, integrated forest products industries and large forest ownerships of the Douglas-fir region are well known. Sometimes overlooked are the 53,000 owners of woodlands of under 100 acres, the average holding being 35 acres. These small tracts, totaling 1,900,000 acres, are growing timber at rates far below their potential.¹ To secure localized information helpfuI to these owners, a 40-acre tract on the McCleary Experimental Forest² in Grays Harbor County, Wash., has been managed for the past 13 years to demonstrate that an annual income can be produced from thinnings, and, at the same time, the potential growth of the land can be maintained or even increased.
