With respect to geologic setting, the Carolina Sandhills NWR consists of Quaternary sands of eolian (wind-blown) origin that were active episodically from ~75,000 to 6,000 years ago, but the sands are stabilized by vegetation under modern climate conditions.[3] These Quaternary sands, which are mapped as the Pinehurst Formation, overlie Cretaceous units of sand, sandstone, conglomerate, and mud of fluvial (river) origin that are mapped collectively as the Middendorf Formation.[4][5]
Ecology
The Carolina Sandhills NWR is dedicated to the preservation of a portion of the Carolina Sandhills, a distinct ecosystem characterized by inland sand dunes,[3] thin or absent topsoil, and frequent brush fires.
Current refuge management practices at the Carolina Sandhills NWR include a program of prescribed burnings.[7]
Human history
After attempts to farm this portion of the Sandhills were unsuccessful during the Great Depression, the region was consolidated by New Deal federal managers into the current National Wildlife Refuge in 1939.
