Abstract

In planning thinnings and final harvest cuttings for stands of young-growth Douglas-fir, foresters need reliable information on the capacity of young-growth stands to bear seed, on the periodicity of seed crops, and on the effects of thinning and other forest practices on seed production. One of the first studies designed to help provide this information was begun in 1950.
