Abstract
Annual dry matter increments in stems and branches of mature aspens (Populus tremuloides) were estimated from a regression of oven-dry weight on stem diameter and from ring width measurements. Before a local outbreak of forest tent caterpillar (Malacosoma disstria), the largest trees increased annually by about 6 kg per tree, the smallest by less than 2 kg. At the middle of the outbreak all trees produced less than 1 kg annually. The method described provides rapid quantitative description of the recent history of annual dry matter production in the aerial portions of trees. Forest Sci. 18:135-138.
