  1. Monitoring of Biological Integrity in Tributaries to the Lower Fox River, Wisconsin The Lower Fox River Watershed Monitoring Program May 19, 2004

  2. We end, I think, at what might be called the standard paradox of the twentieth century: our tools are better than we are, and grow faster than we do. They suffice to crack the atom, to command the tides. But they do not suffice for the oldest task in human history: to live on a piece of land without spoiling it. Aldo Leopold, 1938

  3. Fish Are In Trouble  HERE !Threatened Species per Country USA leads the Way

  4. Lake Sturgeon (below DePere Dam)

  5. Urbanization & the Loss of Fish SpeciesSoutheastern Wisconsin Wang et. al. 1998

  6. Effects of Urbanization on Stream Biological and Habitat Integrity • Increased Peak Flow • Decreased Baseflow • Increased Bank Erosion • Decrease Water Quality • Substrate Degradation • Habitat Loss • Species Loss - Fish, Invertebrates, Plants

  7. Social & Economic Natural Landscape Factors Land Use Patterns Abiotic Responses Primary Production  Benthic Invertebrates  Fish Community Hydrology  Chemistry  Habitat Biotic Responses Continuum of Effects in Watersheds

  8. Data Collected & Analyzed • Stream Hydrology and Water Quality • Stream Habitat Quality • Aquatic Macroinvertebrate Abundance and Diversity • Fish Abundance and Species Composition

  9. Some Fishes of the Fox River and its Tributaries
