Kathleen is a research scientist with the Aquatic Ecology Group at PSW. She has worked on a variety of marine and freshwater research projects in the US and Canada. Since starting at the Forest Service in 1992, she has led several research projects primarily in the Sierra Nevada on the effects of management activities (cattle grazing, fish stocking, etc.) on the native aquatic organisms of wilderness streams and lakes.
