Summary:

This report documents the history and results of the Rocky Brook installation of the cooperative levels-of-growing-stock (LOGS) study in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), over the 41-year period 1965 to 2006. This 1938 plantation is one of the two site-IV installations among the nine installations in the study Much public ownership in the region is on similar poor-site lands. Results are generally consistent with those from the other LOGS installations, although growth has been much slower than in the installations on more productive sites. Volume production increased with growing stock. Periodic annual increment is still considerably greater than mean annual increment. On similar public lands, rotations considerably longer than indicated by conventional economic analysis could reduce land use conflicts and increase carbon sequestration, while maintaining or increasing long-term timber output and timber-related revenues. The principal future value of the data is for use (in combination with other data) in development of growth models.
