Cache River Wetlands Center. Join Refuge Biologist Karen Mangan to learn about 12 species of bats found in the Cache River Watershed. With the installation of artificial roosts and use of acoustic detectors, Refuge staff has been able to identify bats and monitor their activity on the Refuge. The evening includes an indoor program from 6:30-7:30pm followed by an optional field trip on the Refuge to experience bats’ evening emergence. Questions, call Cypress Creek NWR office at 618-634-2231.
