Results of the Hoskins levels-of-growing-stock (LOGS) study in western Oregon are summarized and management implications discussed through the fifth and final planned treatment period. To age 40 thinnings in this low site I Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stand resulted in large increases in diameter growth with reductions in basal area and volume growth and yield. Growth was strongly related to the level of growing stock. Culmination of cubic-foot mean annual increment does not appear to be near for any of the treatments.
