Abstract: Stream research at Coweeta Hydrologic Laboratory has been directed primarily towards an understanding of long-term responses to logging. Forest logging causes many changes in streams including physical alterations of habitat, changes in hydrologic, chemical, and thermal characteristics of the water, and alterations in the quantity and quality of food resources. Studies at Coweeta have demonstrated that stream recovery from forest disturbance is a long-term process. While stream ecosystems have the potential for rapid recovery from disturbance, this potential is not realized because of stream dependence on inputs from the slowly recovering terrestrial vegetations.
