DescriptionDuring winter 1982-83, five silvicultural treatments were applied on Willow Island (near Fairbanks, Alaska): two types of shelterwood cuttings, a clearcutting, a clearcutting with broadcast slash burning, and a thinning. The effects of these treatments on vegetation, soil temperature, and frost depth were followed from 1983 through 1985. In 1984 and 1985, logged plots had significantly higher soil temperatures than did the controls; clearcut and burned sites had the greatest increases. Vegetation composition was profoundly changed on the clearcut and burned units and altered to a lesser extent on the units receiving the other treatments.
