AbstractEfficiency of harvest, overstory regrowth, and regeneration establishment are compared among 12 even- and uneven-aged regeneration cuttings installed in 1984 in subalpine Engelmann spruce and lodgepole pine forests on the Fraser Experimental Forest in central Colorado. Individual tree selection and overstory removal prescriptions were much less efficient to log than two- or three-step shelterwood cuts, clearcuts, or group selection cuts. Considerable overstory growth has occurred in all treatments, but most noticeably in the spruce-fir shelterwood and lodgepole pine uneven-aged treatments. Abundant regeneration was present in all treatments, but subalpine fir dominated in partial harvest treatments, illustrating the need for precommercial thinning in subalpine forests.
