This report documents the history and results of the Iron Creek installation of the cooperative Levels-of-Growing-Stock (LOGS) study in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), over the period 1966-2006 (ages 19 to 59). This is a 1949 plantation on an excellent site, and is one of nine installations in the study. Results are generally consistent with those from other LOGS installations. Volume production of thinned stands increased with increased growing stock. Current volume growth shows no sign of decreasing, and is still about twice mean annual increment. On similar public lands, rotations considerably longer than indicated by conventional economic analyses could reduce land use conflicts and increase carbon sequestration while maintaining or increasing long-term timber outputs. Small plot size prevents further thinning, which would otherwise be desirable in some treatments. The principal future value of the data is for use (in combination with other data) in development of growth models.
