Bringing Native Trees Back into the Bay Area’s Suburban Landscapes.

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.

Management Tools for Landscape-Scale Restoration of Ecological Functions

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

Six coastal wetland systems in north San Diego County: Buena Vista, Agua Hedionda, Batiquitos, San Elijo, San Dieguito, and Los Peñasquitos lagoons

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

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.

News and Notables


Chemistry World, Scientific American, KRCB North Bay Public Radio, and others tackled the story featured on the front page of the San Francisco Chronicle. With respect to the family of chemicals called PBDEs, there appears to be some very good news to report.


How does responsible stewardship of a cultural landscape balance history and ecology?


Several new CRAM training tools and enhancements are now available on the CRAM website and EcoAtlas.


The SF Chronicle features a story describing how scientists have found evidence of widespread and rapid declines in flame retardant pollution in many San Francisco Bay species, according to a new study released by the San Francisco Estuary Institute.


Ariel Rubissow-Okamoto’s article “Stormwater: Beyond the Bag Ban,” based on interviews with SFEI Senior Scientist Lester McKee, BASMAA program representatives Chris Sommers and Matt Fabry, and Tom Mumley of the Water Board, provides a timely overview of stormwater pollution concerns and management directions ahead of the re-issuance of the Municipal Regional Stormwater NPDES permit (MRP).


The Riparian Zone Estimator Tool (RipZET) is a GIS-based decision support tool under development for estimating riparian zones at the watershed and/or project scale. The tool provides reach-scale functional riparian width estimates based on average height of mature riparian vegetation, the steepness of hillslopes adjacent to the channel, and the floodplain inundation extent for large storm events. The appropriate width estimate for a reach is then determined based on the riparian functions associated with different channel types, which range from steep headwater channels to low-gradient, meandering channels with broad floodplains.


With the recent upload of the Klamath Tribes water quality data (1990-2013) by Randy Turner and the Data Services Team, SFEI's Regional Data Center database now contains over 2 million results!


The recent EcoAtlas release delivers new functionality and enhancements to the Landscape Profiler, a tool that summarizes ecological information at various spatial scales for assessment, planning, and reporting. Users can upload a KML file, edit the boundary, and save a polygon for their area of interest. Additional datasets are summarized in the Landscape Profile Report, including the revised 2011 National Land Cover Dataset, eelgrass survey data along the coast from Humboldt Bay to San Diego Bay, and percentages of languages spoken from the US Census data. A date slider helps to visualize the extent of eelgrass surveys over time.


"SFEI could make art objects out of its reports and sell them"


The RMP Update provides a concise overview of recent RMP activities and findings, and a look ahead to significant products anticipated in the next two years. In a new "ebook" format, accessible on any browser, the RMP Update now offers new ways to interact with report content.


An interactive map showing riverine-tidal interface types around San Francisco Bay has been launched!
