An Environmental History of the Tillamook Bay Estuary and Watershed

Historical research was performed to characterize and quantity cultural and natural resource trends within the Tillamook Bay estuary on the Oregon Coast. The research documented a history of environmental changes in Tillamook Bay and its watershed since the time of the Euro-American settlement. A characterization of these changes was done by focussing on key indicators of environmental change, including sedimentation, water quality and estuarine, wetland and riverine habitat. The environmental history findings are intended to provide insight for future resource management decisions in the estuary, as part of the Comprehensive Conservation and Management Plan (CCMP) for the EPA Tillamook Bay National Estuary Project (TBNEP).
