Projects Related to the Historical Ecology

Delta Landscapes Project

The Delta Landscapes Project, which began in 2012 and will run through 2016, has developed a body of work to inform landscape-scale restoration of the Sacramento-San Joaquin Delta ecosystem.


California's EcoAtlas provides access to information for effective wetland management. EcoAtlas is a set of tools for generating, assembling, storing, visualizing, sharing, and reporting environmental data and information. The tools can be used individually or together, and they can be adjusted or tuned to meet the specific needs of environmental planners, regulators, managers, scientists, and educators. The maps and tools can be used to create a complete picture of aquatic resources in the landscape by integrating stream and wetland maps, restoration information, and monitoring results with land use, transportation, and other information important to the state’s wetlands.

Sacramento-San Joaquin Delta Historical Ecology Study

The San Francisco Estuary Institute-Aquatic Science Center, in collaboration with the California Department of Fish and Game, has completed a historical ecology study of the Sacramento-San Joaquin Delta. The project improves understanding of what the Delta looked like and how it functioned prior to the significant modification that has occurred over the last 160 years.

Coyote Creek Watershed Historical Ecology Study

This report synthesizes historical evidence into a picture of how Coyote Creek looked and functioned before intensive modification. Prepared for the Santa Clara Valley Water District, the report helps explain contemporary landscape conditions and identify options for watershed restoration, natural flood protection, and integrated water management.

Tijuana River Valley Historical Ecology Investigation

The Tijuana River Valley Historical Ecology Investigation synthesized hundreds of historical maps, photographs, and texts to reconstruct the the ecological, hydrological, and geomorphic conditions of the valley prior to major European-American landscape modification.

Western Santa Clara Valley Historical Ecology Study

This study produced GIS layers and a report describing historical habitats in the Guadalupe, West Valley, and Lower Peninsula Watershed Management Areas of Santa Clara County (the valley floor from Palo Alto to San Jose).

Resilient Silicon Valley

Drawing on resilience science, regional data, and local expertise, we will develop the vision and tools that will allow stakeholders in the region ensure that local actions contribute toward the creation of a high-functioning and resilient Silicon Valley ecosystem.

Ventura County Historical Ecology Study

This project investigated the historical ecological patterns and hydrological dynamics of most of lowland Ventura County.

Alameda Creek Historical Ecology Study

The Alameda Creek Historical Ecology Study assesses watershed conditions prior to significant Euro-American modification, as a basis for understanding subsequent changes in watershed structure and function, and potential options for future environmental management. The geographic focus is the floodplains, valleys, and alluvial plains adjacent to Alameda Creek (to the diversion dam) and its tributaries. This includes the Livermore and Amador valleys, Sunol Valley and Niles Canyon, and the Niles cone and adjoining baylands. A pilot portion of the project also focuses on documenting landscape changes in the uplands of the San Antonio Creek watershed.

Petaluma Valley Historical Hydrology and Ecology Study

This project reconstructs the historical hydrology and ecology of the Petaluma River watershed prior to major Euro-American modification. It demonstrates the efficacy of historical hydrology and ecology in identifying and prioritizing multi-benefit restoration opportunities.
