North Carolina's Western counties are home to one of the country's rarest natural habitats, mountain bogs. As Asma Khalid reports, the federal government is on a mission to preserve this unusual landscape by creating a national wildlife refuge in Southern Appalachia.
Asma Khalid: If you've never visited a mountain bog, think of a mini swamp, but isolated and patchy. Mountain bogs breed diverse creatures, and sometimes even endangered species.
