Abstract

A survey of shelterwood cuttings in mixed conifer and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests in the Cascade Range in Washington showed that, on the average, shelterwood units were adequately-stocked with a mixture of advance, natural postharvest, and planted reproduction of a number of species. Shelterwood cuttings in the Douglas-fir type had abundant regeneration, whereas those in the mixed conifer type had generally adequate stocking but fewer seedlings. Much of the understocking appeared to be related to a nonuniform overstory, lack of advance reproduction, or high elevation.
