this investigation, which took place as part of the forest watershed and riparian disturbance (forward) study in west-central alberta on the boreal plain, measured key components of a nitrogen (n) budget in a relatively undisturbed, forested watershed. the first component examined was n inputs from bulk deposition and the effect of different forest soil/canopy types (upland deciduous, upland conifer and wetland conifer stands) on n flux from the bulk deposition to the forest floor.
