Abstract

Results of the first 20 years of the Stampede Creek levels-of-growing-stock study in southwest Oregon are summarized. To age 53, growth in this site III Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stand has been strongly related to level of growing stock. Marked differences in volume distribution by tree sizes are developing as a result of thinning. Periodic annual increment is about twice the mean annual increment in all treatments, which indicates that the stand is still far from culmination.
