Abstract

During the early 1930's, as use of the logging truck and tractor increased, a form of partial harvesting mature and overmature virgin stands developed in the Douglas-fir region (2). The cutting pattern varied from taking a few scattered high-grade trees per acre to clear cutting small areas. Partial harvesting caught on quickly because at that time only the high-grade trees could be logged at a reasonable margin of profit. This was a new procedure in the Douglas-fir type, and its effect on the future stand was unknown.
