  1. Landscape Change in the Napa River Watershed, 1800–2002: Implications for the Restoration of In-Stream, Floodplain, and Valley Floor HabitatGrossinger, R., Striplen, C., Brewster, E., San Francisco Estuary Instituteand L. Collins, Watershed SciencesCALFED Science ConferenceJanuary 16, 2003

  2. Project Goals • a map of the pre-European impact fluvial system • extent of floodplain • location of distributary systems, side channels, riparian habitat  flood control, stream restoration, fisheries recovery • a map of the pre-European impact distribution and abundance of valley floor habitats • oak savanna • seasonal wetland/vernal pools • native grassland  conservation planning (identifying remnants, proportional representation, designing corridors and mosaics) • land use history • spatial extent and duration of grazing, logging, ditching, etc.  identify early uses which may have ongoing effects • community-participatory process acquire needed data greater shared understanding of how the current landscape has evolved and its potential for restoration

  3. Presentation Outline 1. Approach • Partnerships • Issues of scale 2. Methods • 19th-century Historical Documents • Early Aerial Photography • Mapping of Present-day Ecological Remnants 3. Preliminary Findings — methodological and technical • Pleasures and Pitfalls of Historical Sources • Discovery of Counter-Intuitive Changes • Substantial Variation in Historical Landscape within a Small Area ( variation in present-day geomorphic controls)
