This project is the first regional assessment of the relative distribution and abundance of different wetland habitat types along the historical Southern California coastline.

Rebuilding Habitat and Shoreline Resilience through a New Generation of Flood Control Channel Design and Management

Management Tools for Landscape-Scale Restoration of Ecological Functions

This historical reconstruction documents habitat types throughout the Delta to better understand the native landscape. Knowing how different parts of the vast historical Delta looked and functioned provides information for future restoration.

This study will assess 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 tidal-terrestrial transition zone has been recognized as an important component of the San Francisco Bay, and has been identified as a high priority for restoration in the South Bay and for the Bay as a whole. This project reconstructs the approximate extent of the South Bay T-zone and characterizes it in terms of the adjoining terrestrial and intertidal habitat types and features that were historically prevalent in the region.

BAARI is a base map of the Bay Area's aquatic features: wetlands, open water, streams, ditches, tidal marshes and flats, and riparian areas.

The study area encompasses the estuarine and alluvial portions of the Tijuana River watershed from the river mouth in southern San Diego County to the U.S.-Mexico international border. Limited research will also be conducted on an approximately 10 mile stretch of the river extending through Tijuana, Mexico.

The Annual Meeting of the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) will be held on Tuesday, October 14, 2014 at the David Brower Center in Berkeley, CA from 9 AM to 4 PM.


SFEI recently completed a pilot study focused on creating a framework for a rapid protocol that can be used to delineate the current and future HoT zone for San Francisco Bay tributaries using both “desktop” and field investigations.


New study points the way to habitat restoration and steelhead recovery on Alameda Creek, the Bay Area’s largest local watershed.


In collaboration with BASMAA, RMP, the Regional Water Board and stormwater agencies, SFEI leads a multi-year stormwater monitoring project within the San Francisco Bay area. While this sampling effort fulfills monitoring requirements under the Municipal Regional Permit (MRP), it also contributes to the region’s long-term stormwater dataset.


EcoAtlas, SFEI's flagship product launched last summer, was just awarded three Wetland Program Development grants by the USEPA for further enhancement and support.


"Environmental Informatics" is the new and inclusive name for the SFEI technology program that produces, manages, and analyzes information for the benefit of California's aquatic resources.


A recent RMP technical report summarizes a series of RMP monitoring and research projects that have investigated the impacts of the flame retardants polybrominated diphenyl ethers (PBDEs) in San Francisco Bay.


The Resilient Landscapes (RL) team delivered a number of presentations during the last quarter highlighting recent accomplishments and initiatives.


Phil Trowbridge, formerly of the Piscataqua Region Estuaries Partnership and the New Hampshire Department of Environmental Services, joins SFEI to serve as the San Francisco Bay RMP Manager. SFEI feels very fortunate to attract such a high-caliber professional engineer with an admirable list of accomplishments.


Bayfront water levels are forecast to rise 1 foot by 2050
