Flat Rock Cedar Glades & Barrens State Natural Area
🏆🏆 Cedar Glade & Barrens Mosaic — Exceptional example of the Nashville Basin’s signature landscape
Flat Rock Cedar Glades & Barrens State Natural Area preserves one of the finest examples of the Nashville Basin’s globally unique cedar glade and barrens mosaic. The site features extensive flat limestone outcrops with thin soil supporting endemic plants, seasonal vernal pools that host fairy shrimp and other ephemeral aquatic life, and open grassland interspersed with red cedar stands. Multiple state-listed plant species grow here, including species found only in the Nashville Basin.

Frequently Asked Questions
What are vernal pools?
Vernal pools are seasonal depressions in limestone that fill with rainwater in winter/spring and dry out by summer. They support unique organisms like fairy shrimp that have adapted to this temporary aquatic habitat.
About Flat Rock
Flat Rock Cedar Glades and Barrens State Natural Area in Rutherford County protects an extensive complex of cedar glades and limestone barrens — two of Tennessee’s most distinctive and globally rare plant communities. The flat limestone exposures create extreme conditions (flooding in winter, desert-like drought in summer) that support highly specialized endemic plants.
Things to Do
Viewing the diverse cedar glade and barren ecosystems, observing endemic plants adapted to extreme conditions, botanical study and photography, and learning about these globally significant habitats.
Insider Tips
Flat limestone pavement: Flat Rock exposes broad sheets of bare limestone — resembling a desert pavement but supporting remarkable wildflower displays in the thin soil cracks. Pro tip: After spring rains, temporary pools on the limestone host fairy shrimp — tiny crustaceans that complete their entire life cycle in puddles before they evaporate. Prickly pear: Eastern prickly pear cactus grows here — a surprising sight in lush Tennessee.
Best Time to Visit
Spring: Temporary pools with fairy shrimp and early wildflowers. Summer: Cactus bloom and coneflower season. Fall: Golden grass and asters. After rain: The limestone pavement transforms with temporary water features.
Frequently Asked Questions
There are cacti in Tennessee?
Yes — eastern prickly pear cactus (Opuntia humifusa) grows naturally on Tennessee’s cedar glades. The hot, dry limestone pavement mimics desert conditions — baking in summer sun and shedding water quickly. These micro-habitats support species typically associated with the western US — a surprising botanical quirk of Middle Tennessee.
