Project: Southern California Coastal Wetland Change Analysis

Description: A grant to Southern California Coastal Water Research Project Authority for a cooperative project with the State Coastal Conservancy (SCC) and the U.S. Fish and Wildlife Service (FWS) to provide an initial estimate of change in extent and composition of Southern California’s coastal wetlands in Santa Barbara, Ventura, Los Angeles, Orange, and San Diego Counties. The useful life is 25 years. The goal of this project is to provide an initial estimate of change in extent and composition of southern California’s coastal wetlands between circa 1850 and 2005. The analysis will be based on a comparison of wetlands mapped on the historical U.S. Coast and Geodetic Survey topographic maps created between 1850 and 1880 with the contemporary FWS National Wetlands Inventory maps. Previous work in southern California provided a foundation for long-term change analysis by acquiring, digitizing, and analyzing coastal wetlands based on the historic maps. This project would build upon past efforts by augmenting historical analysis and comparing historical and contemporary coastal wetland mapping. The scope of work covers the acquisition of 25 additional historic maps to complete basic documentation of the southern California coast, compare them to contemporary wetlands mapping, and analyze the habitat changes that have occurred along the southern California coast. The goal is to provide an initial estimate of change in coastal wetlands between the mid-19th century and today.
