Several animals that were extirpated from the Southern Appalachians are now making a comeback. Beavers, elk, peregrine falcons, and river otters, not long ago gone from the Southern Appalachians can now be found along the parkway. Others that were reduced to low numbers, such as wild turkeys and black bears, are making a strong comeback. Together these animals help to restore the biological health of the Blue Ridge Parkway.
