"As if to mock our attempts to keep these foreign creatures from entering our country on nursery stock, ...the balsam woolly adelgid (Adelges piceae), has all but eliminated the Fraser fir (Abies fraseri) from the high altitudes of the Great Smoky Mountains National Park.... Because Fraser firs are endemic to the Smokies (found nowhere else in the world), their loss from the area is equivalent to their extinction." — Douglas W. Tallamy, Bringing Nature Home
