James River Bat Cave
Information Line

This unique preserve is home to 4 million to 6 million Mexican free- tailed bats and one of the largest concentrations of warm-blooded animals in the world. The cave supports a maternity colony where females give birth to and raise their pups. Because this species roosts in such large numbers, colonies are vulnerable to disturbance and could be destroyed by a single destructive act. Additionally, the population recovery rate for a colony of Mexican free-tailed bats is slow because females give birth to only one pup each year. Richard Phillip Eckert and Virginia Eckert Garrett donated the cave to The Nature Conservancy in honor of their father, Lee Eckert, and grandfather, W. Phillip Eckert. The Eckert family acquired the property in 1907 when W. Phillip purchased the ranch on which the cave is located. In the early 1900s, W. Phillip mined the bat guano in the cave and sold it to local farmers for crop fertilizer. W. Phillip’s son, Lee Eckert, continued his father’s legacy of bat conservation and guano mining and left the site to his wife and children when he passed away in 1967. This generation of Eckerts wanted to ensure permanent protection of the bats, so in 1990, they donated the cave to The Nature Conservancy on condition that the land around the cave remain open to the public for enjoyment and education, as it had been for more than 100 years.
