Publication Series: General Technical Report (GTR)

Description: Controlled-exposure studies have shown that several plant species native to the Pacific Northwest are potentially sensitive to elevated ambient concentrations of tropospheric ozone. This guide reports visual and descriptive documentation of ozone injury symptoms for common tree, shrub, and herbaceous species in the region. Symptoms observed in leaves of these species include chlorotic mottle, pigmented stipple, necrosis, and premature senescence, with considerable variation among and within species. Resource managers and scientists can use the photo documentation in this guide to identify potential injury to plants in the field, and to distinguish ozone injury from other pathological conditions.

Keywords: air pollution, forest health, forest pathology, ozone, vegetation injury
