The Nature Conservancy [www.nature.org] says it has completed an artificial cave in Tennessee that should provide a safe refuge from White-nose Syndrome for as many as 250,000 hibernating bats. The subterranean structure, built of precast concrete culverts and covered with soil, will be disinfected each summer after the bats leave. The 78-foot-long cave was completed September 11, and the Conservancy is hoping the first bats will move in this fall andwinter. Learn more.
