Air pollution injury on Pinus Strobus in Acadia National Park - 1985 survey results. Final report

Technical Report ·
OSTI ID:6503676

Visible symptoms of ozone injury were observed on 90% of the Eastern white pine trees (Pinus strobus) sampled in 1985 from permanent pine plots at Acadia National Park. Average injury was low and affected about 4% of the needle surface. Only 10% of the trees sampled had more than 10% injury. Chlorotic mottle was the most common symptom encountered, followed by fleck injury and tipburn. Total ozone injuries were significantly higher than those observed in a similar sample from Great Smoky Mountains National Park; however, the trees at Acadia had notably lower injuries from other biotic and abiotic causes.
