Ozone Risk Assessment for Vital Signs Monitoring Networks, Appalachian National Scenic Trail, and Natchez Trace National Scenic Trail

Kohut RJ. 2007. Ozone Risk Assessment for Vital Signs Monitoring Networks, Appalachian National Scenic Trail, and Natchez Trace National Scenic Trail. NPS/NRPC/ARD/NRTR—2007/001. National Park Service. Fort Collins, Colorado

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. Initial assessments were completed in 2004 using ozone monitoring data from 1995 through 1999. A reassessment of ozone risk was completed in 2007 for 8 National Park units using monitoring data from 2000 through 2004 in parks that appeared to experience increased levels of ozone exposure since the initial assessment. Together the two assessments provide insight to the changes in ozone exposure over a ten-year period, and examines how the changes may have altered the risk of ozone injury to plants.
