Background
Tim has worked in fisheries resource management since 1984, beginning with fish population assessments and catch monitoring in West African lakes as a Peace Corps volunteer. He later spent nine years with the Skagit River Indian tribes assessing impacts of land uses on salmonid habitats, potential recovery from increased sediment supply and loss of wood, and restoration strategies for Pacific Northwest river basins. He is currently the Science Coordinator for the Watershed Program, and Leader of the Ecosystem Processes Team. He holds a B.S. degree in geology (1983), a M.S. in fisheries (1990), and a Ph.D. in forestry (1998), all from the University of Washington.
Current Research
Since 1990, Tim has studied the natural development of landscapes and salmon habitat, evaluated the relative influences of different land uses on salmon habitat losses, and led the development of a process-based habitat restoration strategy. He has conducted research on the influence of woody debris on fish habitat, recruitment of woody debris from second-growth forests, and recovery of salmon habitat from landslide impacts and removal of riparian forests. He is currently studying the formation and evolution of floodplain habitats, impacts of sediment supply changes on stream habitats, and restoration of incised stream channels in semi-arid environments.
