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.
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.

Prickly pear: Eastern prickly pear cactus grows here — a surprising sight in lush Tennessee.
