My research is directed toward improving our understanding of the fundamental processes and principles of water and nutrient movement through forests and how these may be impacted by our land management activities. I am focusing on spatial and temporal variability of nitrogen and phosphorus concentrations under natural conditions and after disturbances in the Trask Watershed. Through modeling of the relationship between N and P variability and morphometric, soils, geologic, and climatic variables at the catchment scale, controls on nutrient variability under natural and disturbed conditions can be identified. Additionally, natural relationships and potential impacts of increased N and P concentrations due to disturbances on biological parameters (primary producers, macroinvertebrates, stream metabolism) can be quantified.
