SFEI conducted a historical ecology assessment of natural resources in East Contra Costa County in partnership with Contra Costa County and the Contra Costa Watershed Forum. Through the study, SFEI collected and analyzed data to build understanding of the historical alignments of creeks, the natural pattern of riparian and dryland habitat types, and the locations of former seasonal and perennial wetlands. This study developed new methods for assessing uplands, including use of Wieslander Vegetation Type Maps, compiled in the 1920s and 30s. The data developed through the project can help identify valuable habitat remnants, prioritize restoration opportunities and strategies, and recognize landscape trends. The project was been designed specifically to inform the East Contra Costa County Habitat Conservation Plan process.
The project was completed in November 2011.
