Few animals have become one with their habitat quite like hellbenders. The very act of searching for them often means mistaking rocks for hellbenders and hellbenders for rocks. But that close connection to the benthic environment means the health of a hellbender population is inseparable from the health of the riverbed itself. Hellbenders need clean, stable streambeds, free of excessive silt and sediment, and one of the best ways to protect those conditions begins far beyond the water’s edge, in the forest.
A healthy forested watershed acts as a natural filter, slowing runoff and trapping sediment before it reaches the stream. But the connection goes beyond the trees lining the banks. Hellbender streams also depend on a steady supply of large, fallen trees entering the river. Large logs and logjams change the way water moves through a stream. They slow and redirect currents, spread the force of high flows, and help distribute sediment and gravel rather than allowing it to wash downstream all at once. As water moves around and beneath the wood, it scours some areas while depositing gravel and sediment in others, creating a constantly shifting mosaic of pools, riffles, and stable hiding places. That complexity provides habitat not only for hellbenders, but for the aquatic insects, fish, crayfish, and other organisms that make up Southern Appalachian stream ecosystems.
In this way, a hellbender tucked beneath a rock is connected to something much larger than the rock itself. It is connected to the forest.
Follow along with Freshwaters Illustrated over the coming years as we work alongside biologists from the University of Montana, USDA Forest Service, N.C. Wildlife, The Nature Conservancy and Trout Unlimited to better understand these connections in Southern Appalachian streams and what they mean for the future of hellbenders, and all the life that call these rivers home.
