William Davenport Refuge is 120-acre natural area located in Polk County. It was named after the previous owner's father. The area is significant for both ecological and historical reasons. The ecological aspects are exceptional due to the occurrence of a rare Southern Appalachian bog community. The bogs contain cranberry (Vaccinium macrocarpon) and tawny cotton-grass (Eriophorum virginicum), both rare species in Tennessee. It is hypothesized that this unusual bog community is a refuge of northern boreal species that migrated into the Blue Ridge from more northern latitudes during the last ice age. The area is significant from a historical standpoint since the land exists within the Copper Basin, a physical feature that dominates extreme southeast Tennessee, a part of southwestern North Carolina, and northern Georgia.
