Dead Fraser Fir, Abies fraseri, trees - victims of Balsam Wooly Adelgid, Clingman's Dome, Great Smoky Mountains National Park

---

Fraser Fir trees are native to the high elevations (above 4,500 feet) of the southern Appalachian Mountains. Most of the adult Fraser Firs have been killed by the Balsam Wooly Adelgid, an aphid like insect accidentally imported to North America on nursery trees. Stress from acid precipitation and ozone pollution may have contributed to the impact on the fir trees.
