Cumberland Piedmont Network Ozone and Associated Foliar Injury Monitoring

Jernigan J. Cumberland Piedmont Network Ozone and Associated Foliar Injury Monitoring. 2001. National Park Service

Ozone is a naturally occurring gas that can also be generated in reactions with anthropogenically created nitrogen oxides. While stratospheric ozone prevents ultraviolet radiation from making its way to the Earth’s surface, tropospheric ozone that is in higher than naturally occurring concentrations can have harmful effects on the health of people and plants. The goals of ozone reporting and foliar injury monitoring are to assess exposure to ozone and its impacts to susceptible plant life at those parks. The Cumberland Piedmont Network monitors between one and three foliar injury sites within each park. The number of foliar sites depends on availability of sites with adequate ozone-sensitive species richness and abundance living under abiotic conditions that can manifest injury. Parks are sampled on a panel design, with three to four parks sampled each year over the course of a six-year sampling rotation. That sampling is completed annually between late July and late August. Data collected in each site include individual plant assessments of symptomology, site mapping, and site conditions. Ozone exposure indices are retrieved from sources outside the Cumberland Piedmont Network.
