Tree damage resulting from thinning in young-growth Douglas-fir and western hemlock.

Abstract

Thinning trials on three cooperative experimental forests in western Washington have provided an excellent opportunity to evaluate tree damage resulting from typical thinning operations in young-growth timber. The type and degree of damage can, of course, be expected to strongly affect condition and vigor of the residual stand and ultimate success of a thinning regime.
