Ozone Risk Assessment for Vital Signs Networks

Ozone risk assessment employs a biologically-based method to evaluate the risk of foliar injury from ozone at parks within the 32 Vital Signs Networks, the Appalachian National Scenic Trail, and the Natchez Trace National Scenic Trail. The assessment allows resource managers at each park to better understand the risk of ozone injury to vegetation within their park and permits them to make a better informed decision regarding the need to monitor the impacts of ozone on plants. Select a Vital Sign Network or National Scenic Trail from the map or list below to view an assessment. Assessments were not done for the Alaska and Pacific Islands networks; ozone estimates could not be made for park units in those networks because of the relative lack of monitoring data. Based on the limited ozone data available (from monitors at Denali NP and Hawaii Volcanoes NP), the risk of foliar injury from ozone in Alaska and the Pacific Islands networks is considered low. Assessments are in PDF format (70 - 400kb). A Network Risk Assessment Table, also in PDF format (494kb), provides summary information on risks for all networks.
