This publication is intended as an introduction to how historical ecology can help local residents and resource managers understand current conditions and develop strategies for environmental recovery in the Sonoma Creek watershed. The watershed has experienced substantial physical and ecological change due to the history of human activity and development. Understanding this history can help identify opportunities to restore natural watershed function within the contemporary landscape. This document highlights areas of interest for potential restoration including historical freshwater wetlands and stream channels in the watershed. The highlighted opportunity areas will guide the stakeholders of the Sonoma Creek watershed participating in the Critical Coastal Areas (CCA) Program pilot study to identify and prioritize actions that will improve watershed health.
