| dc.description |
In 1998, forest vegetation was monitored for ozone injury on permanent plots in two Sierra Nevada national forests in California, at three locations in Mount Rainier National Park in Washington, and at 68 forest health monitoring (FHM) locations throughout Washington, Oregon, and California. This was the first year that extensive monitoring of forest vegetation for ozone injury was carried out in Oregon, and Washington. Injury was detected on ponderosa and Jeffrey pine in the Sierra Nevada permanent plots and on red elderberry at one FHM location in southwest Washington. No injury was detected at the Mount Rainier sites. The authors also report on results of a trial where red alder, huckleberry, blue elderberry, and chokecherry were exposed to ozone under controlled conditions. |
