Success Hands-on activities such as bank stabilization, trash removal, and the fencing of riparian areas to prevent trampling from livestock are all making a difference for plants and wildlife in this ecosystem. These actions have helped to preserve and enhance the Clinch's water quality. There have been significant reductions in sediment from erosion and other pollutants that threaten the aquatic life of the Clinch. Stream- bottom habitats essential for aquatic creatures have been protected from trampling by livestock and the smothering effects of silt and muck. The future of the Clinch River depends on the continuation of such efforts. Residents of Hancock County are learning more about the rich natural heritage of the Clinch River valley thanks to this ongoing project. Gray Bats On The Comeback

Dedicated field biologists, help save and recover species, but it other mammal in the United States. researchers, and conservation minded can be done. To thrive, these bats require cavers have made this possible by undisturbed caves for winter fencing or gating cave entrances and These efforts have been rewarded hibernation, and warm caves for restricting access during the times with a significant increase in the raising their young in the summer. the bats are present. This allows the numbers of gray bats in Tennessee.
