Hemlock Bluffs State Natural Area

Hemlock Bluffs Nature Preserve is a joint project between the North Carolina state park system and Cary, Wake County, North Carolina in the United States. Located in Cary, it covers approximately 140-acre (0.57 km2) in the Research Triangle region of the state. The state owns 97-acre (0.39 km2) of the preserve, known as Hemlock Bluffs State Natural Area. The Town of Cary owns approximately 42-acre (0.17 km2) of the preserve, and the town leases the state's land for management. The preserve protects a population of Eastern Hemlock trees and other vegetation more typically found further west, in the Appalachian Mountains. The tall, north-facing bluffs of Swift Creek provide conditions similar enough to the mountains to have allowed the plant communities to have survived there since the last ice age.
