CHATTANOOGA, Tenn – Red wolves are apex predators, critical to ecological balance.  Without them, the rest of us – humans, other animals and plants – cannot succeed.  Red wolves are endangered:  only seven known in the wild – and 250 under human care.

Here in Chattanooga, Mark McKnight is president and CEO of Reflection Riding Arboretum and Nature Center – and Tish Gailmard is director of wildlife there.
