Bracken Cave Preserve Established Through One Health Assessment

Bracken Cave Preserve Established Through One Health Assessment

The Bracken Cave Preserve is home to the largest bat colony in the world, an estimated 20 million Mexican free-tailed bats (Tadarida brasiliensis). Plans to construct a residential complex along the 1,521-acre tract adjacent to the cave mouth posed a serious risk to wildlife and the potential human population. Motivated by concerns for a nearby aquifer, but limited by a lack of zoning laws in the area, the local government commissioned a report on the potential public health risks of the development. The report outlined concerns for human exposure to various pathogens, from both exploring the cave and the bats’ presence around the new residences. To protect the bat and human populations, advocates from diverse sectors, including conservationists, health experts, city and county governments, and the public water utility, came together to purchase the tract of land. In 2014, the property was officially made into the Bracken Cave Preserve, protecting this area essential for environmental, animal, and human health in perpetuity.
