About Campbell Bend Barrens

These barrens once covered extensive areas of middle Tennessee but have largely been lost to development and fire suppression. The area supports prairie-like plants at the eastern edge of their range.
Things to Do
Observing rare limestone barren plants and grasses, birdwatching for grassland species, botanical study, and photography. These barrens are living remnants of a once-widespread Tennessee ecosystem.
Insider Tips
Cedar glade ecology: Campbell Bend protects one of Tennessee’s unique cedar glades — thin-soiled limestone outcrops supporting rare plants found almost nowhere else. Pro tip: Tennessee’s cedar glades are a globally rare ecosystem — endemic species like Tennessee coneflower (Echinacea tennesseensis) were once believed extinct before being rediscovered here. Limestone bedrock: The shallow soil over limestone creates conditions that exclude most trees but support specialized prairie-like vegetation.
Best Time to Visit
Late spring: Cedar glade wildflower bloom — May/June. Summer: Tennessee coneflower bloom. Fall: Goldenrod and aster season. Winter: Interesting bare-rock geology.
Frequently Asked Questions
What is a cedar glade?
Cedar glades are open rocky areas where thin soil over limestone bedrock prevents most trees from growing — only eastern red cedars and specialized wildflowers thrive. Found almost exclusively in Middle Tennessee’s Central Basin, they support dozens of endemic plant species. Cedar glades are the rarest terrestrial ecosystem in the eastern United States.
