It occurs on the edge of a swampy section of North Carolina’s coastal plain, and the sandy, acidic soil is either wet or submerged. This habitat experiences periodic wildfire every few years which clears brush, creating an open canopy. This fire regime is apparently vital to the rare Carex and other plants that cannot grow if the woody brush grows up and outcompetes them. Fire suppression efforts in the area threaten the plant and its ecosystem; some of the populations occur on private land that is not allowed to burn. It generally does not grow in an area without periodic fires unless it is mowed to clear the brush or it is too wet for large woody vegetation to grow. Other threats include logging and herbicide use. Destruction of the habitat or alterations in its hydrology could damage populations
