摘要

Natural regeneration was good to excellent 5 years after shelterwood cutting to three overstory densities (50, 90, and 130 sq ft per acre) in a mixed conifer stand on the Deschutes National Forest in central Oregon. Seedling density ranged from about 1,875 per acre on the low density plots to 4,627 per acre on the high density plots and consisted of about 85 percent true fir (grand and Shasta red) and 15 percent ponderosa, lodgepole, and western white pine. A residual overstory of about 50 sq ft of basal area per acre appears adequate to provide natural regeneration within a 5-year period.
