What killed the trees? The balsam wooly adelgid, a pinhead-size insect native to Europe, is responsible. It began attacking the Fraser fir forests here in the 1970s. The red spruce, unaffected by the adelgid, survives in the midst of this devastated forest.

Airborne pollutants that change the chemical composition of fog, rain, and snow also might contribute to forest decline. Studies suggest these pollutants combine with moisture in the air to form "acid precipitation," one of the factors suspected of slowing the growth of trees and making them more vulnerable to disease and insect damage.

Scientists are seeking ways to reverse this forest decline. Meanwhile it is possible that future generations of Fraser firs will develop their own defense against these destructive influences.

[ Sidebar : ]
The adelgid usually selects a 15 to 20-year-old tree as a host. It feeds by inserting a slender mouthpart through the tree's bark. This feeding causes cellular changes in the tree that block the tree's ability to transport life-sustaining fluids.
