Approach
Goal
Nitrogen Pollutant Exposure Ecosystem Sensitivity to Nutrient
N Enrichment Park Protection Mandates
Construct preliminary risk assessment of nutrient enrichment impacts from air pollution sources of N to I&M parks.
3
Caveats
Scope Network Assessment (n=32) Park Assessment (n=271)
Preliminary assessment Imperfect knowledge of pollution
exposure and ecosystem sensitivity Limited availability of national-scale
spatial data
4N Pollutant Exposure
Nitrogen Pollutant Exposure VariablesI. N emissions by
countyTotal county-level annual N emissions, as areally weighted average of lands within network, per unit area
II. Human population within network
Total human population per unit area within network
III. Human population within buffers
Total human population per unit area within 100-mile buffer around network
IV. Percent developed land within network
Percent of land within network classified as developed area
V. Percent agricultural within network
Percent of land within network classified as agricultural
VI. Average N deposition within parks
Average total annual N deposition for all park lands that occur within the network
5
Total Nitrogen Emissions by County

Total Nitrogen Deposition

8Ecosystem Sensitivity
Ecosystem Sensitivity Variables
VII. Percent sensitive vegetation types within parks
Percent of land within parks that occur within the network occupied by arctic, alpine, meadow, wetland, arid, and/or semi-arid vegetation
VIII. Number of high- elevation lakes within parks
Number of high-elevation lakes found in or partially within parks that occur within the network
9
10Park Protection
Park Protection Variables
IX. Amount of lands in the park receiving special protection
Area of park lands within network designated as wilderness and/or Class I
X. Percent of lands in the park receiving special protection
Percent of park lands within network designated as wilderness and/or Class I
XI.Percent of network in designated wilderness
Percent of all lands within network designated as wilderness
