Located within Tilden Regional Park in the hills above Berkeley, California, this enchanting 10-acre garden is a sanctuary for many of the state's rare and endangered plants and a place for visitors to wander among trees, shrubs, flowers, and grasses from plant communities throughout the state. The Botanic Garden is welcoming to all visitors from our entire Bay Area community and travelers to the Bay Area.

Twilight Bat Walk
Aug 28
Twilight Bat Walk

The Regional Parks Botanic Garden is home to many native bats! Their sensitivity to habitat and climate disturbance makes them useful indicators of ecosystem health.  Dr. Chelsea Andreozzi spent 407 summer nights monitoring bats using ultrasonic detection equipment across a spectrum of forest management types and microclimates.

Join Dr. Andreozzi for an evening twilight bat walk in the Garden. The evening will consist of a brief classroom portion followed by a walk through the Garden with bat monitors. Meet inside the Visitor Center Auditorium at 6:45pm. Sign up for the walk.
