Foliar injury, tree growth and mortality, and lichen studies in Mammoth Cave National Park. Final report, 1985-1986
Technical Report

OSTI ID:6159701
Foliar condition, tree growth, tree mortality, and lichen communities were studied in Mammoth Cave National Park, Kentucky, to document the present forest condition and to provide a basis for detecting future changes. Foliar injury by ozone was common on many plant species in 1985. Species showing the most injury were white ash, green ash, redbud, sycamore, tulip poplar, milkweed, and wild grape. Injury apparently depended on canopy position and vigor. Tree growth was equivocally related to visible symptoms in 1986, probably because of the low ozone levels in that year. Tree mortality rates from 1966-1985 in two natural stands were somewhat lower than mortality rates known for other midwestern woods.
