Abstract
Ten-year remeasurement of white spruce stems released from aspen competition in Alberta's spruce-aspen forest indicated that over a wide diameter and age range, growth of spruce increased significantly after treatment. Trees above a 5-ineh breast height diameter limit increased in mean merchantable cubic foot volume by 20-40 per cent. Release of spruce from aspen competition should be carried out before the spruce grows into the aspen overstorey. Poisoning cut aspen stumps with ammonium sulphamate prevents regrowth of aspen suckers and sprouts.
