  1. Use of GIS to EvaluateSensitivity of I&M Parks to Effects from Atmospheric Nitrogen Deposition T.J. Sullivan T.C. McDonnell G.T. McPherson E. Porter S.D. Mackey D.L. Moore George Wright Society Meeting March 15th – 17th, 2011 - New Orleans

  2. Goal • Construct preliminary risk assessment of nutrient enrichment impacts from air pollution sources of N to I&M parks. Approach • Nitrogen Pollutant Exposure • Ecosystem Sensitivity to Nutrient N Enrichment • Park Protection Mandates

  3. Scope • Network Assessment (n=32) • Park Assessment (n=271) Caveats • Preliminary assessment • Imperfect knowledge of pollution exposure and ecosystem sensitivity • Limited availability of national-scale spatial data
