Stemflow was collected from live and dead trees of trembling aspen, largetooth aspen, and maple from a mixed deciduous forest in Chalk Riber, Ontario, for each rain event occurring between May and August, 1984. The data showed that the chemistry of dead-tree stemflow is qualitatively differentfrom that of live trees, with dead-tree stemflow contributing verly large prop ortions of the total amount of nitrate and phosphate available within the system. Given the increasing mortality of these tree species in the Chalk River area, dead-tree stemflows may assume major importance in influencing nutrient cycling of nitrogen and phosphorus within the forest.
