Abstract

Seed spots established in the spring of 1953 were remeasured in August 1959. Variables included Engelmann spruce (Picea Engelmanni Parry) and alpine fir (Abies lasiocarpa (Hook.) Nutt.); two site types—wet (VO) and dry (VM); three degrees of light—full shade, part shade, and full sun; and five seedbeds—mineral soil, burn, moss, litter, and rotted wood. The observed data on survival and growth are further evidence of the need to provide adequately disturbed seedbeds to ensure reproduction of Engelmann spruce and alpine fir. The poor survival, even with first-year screening, and slow juvenile growth of these species suggest that planting may have advantages over direct seeding.
