My research is cross-disciplinary with the ultimate goal of scaling plot-based forest health relationships to a landscape-scale using remote sensing and GIS modeling. To date, this work has focused on the detection and mapping of pre-visual forest decline symptoms resulting from invasive species, global climate change and acid deposition/nutrient depletion. These techniques provide a much-needed tool for the early detection of new and existing stressors and will allow forest management agencies to focus management efforts before stands are severely impacted.
