Dead Fraser Firs, the result of balsam woolly adelgid (aphids) infestation due to air pollution, are fast becoming a common part of the landscape at Great Smoky Mountains National Park, which spans the borders of North Carolina and Tennessee, and is one of the largest protected areas in the eastern United States. The Great Smoky Mountains, named for naturally-occurring mist-like clouds that frequently surround the mountains, are affected by air pollution from nearby industry, power plants, and cars. The pollution appears as a uniform haze, which threatens the health of flora and fauna and degrades visibility. The National Park Service works with state agencies to monitor nearby industry to minimize the amount of new pollution produced and carefully monitors the air quality in the park.
