🦇 20 million bats need a little mower power!
Bracken Cave Preserve is home to the world’s largest known bat colony—and protecting it means caring for the 1,500 acres surrounding the cave.
After 19 years, our trusty mower has mowed her last acre. This Big Give, help us raise $6,000 for a new one and keep Bracken wild and thriving for bats, wildlife, and people.
🚜 Give Big for Bracken!
