The Green Swamp is a swamp that lies in Brunswick and Columbus counties in North Carolina. The 15,907-acre (6,437 ha) swamp was designated a National Natural Landmark in 1974. The carnivorous plant known as the Venus Flytrap is found within this swamp, and it is important for other unique and endangered species. North Carolina laws prohibit the removal of these plants from their habitat. The wetlands support a rich ecology and are important as habitat along the Atlantic Flyway of migrating birds and other species.
