North Bay Mercury Biosentinel Monitoring (Project)

In 2011-2014 SFEI and UC Davis developed and implemented a multi-species biosentinel monitoring approach as an effective and efficient way of monitoring methylmercury exposure in wetland restoration projects across the North Bay. The monitoring design for this project was developed with input from a Science Advisory Group (SAG) of regional and national experts and input from local stakeholders, in order to build a design that would address questions of management concern.

Petaluma Valley Historical Hydrology and Ecology Study (Project)

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.

Understanding Change in Primary Production at a Landscape Scale in the Delta (Project)

Constraints on primary production and the relative importance of different production sources to the food web remain major uncertainties in the Delta ecosystem. Newly available spatial data developed as part of the Delta Historical Ecology and Delta Landscapes projects make it possible to explore the effects of landscape configuration and hydrodynamics on primary production in a way that was not previously possible. Proposed order-of-magnitude calculations estimating primary production can ‘bookend’ the potential magnitude of production in the Delta, and inform what is possible in terms of restoration and management options.

Peninsula Watershed Historical Ecology Study (Project)

The Peninsula Watershed, located in San Mateo County on the San Francisco Peninsula, is the site of three of the Bay Area’s largest reservoirs—San Andreas, Upper and Lower Crystal Springs, and Pilarcitos—which provide drinking water for residents throughout region. Encompassing the upper portions of San Mateo Creek and Pilarcitos Creek watersheds, the “Peninsula Watershed” also supports some of the largest intact remnants of contiguous habitat in the region, including extensive oak woodlands, old-growth Douglas Fir forests, serpentine grasslands, and chaparral.

Sycamore Alluvial Woodland Habitat Mapping and Regeneration Study Released (News)

California sycamore (Platanus racemosa) is an iconic native tree species found in California and northern Baja California. The health and regeneration of California sycamore have been substantially affected by a wide range of factors, including hydrologic modifications of creeks, hybridization with London plane tree (Platanus x hispanica), and anthracnose.

Sycamore Alluvial Woodland Habitat Mapping and Regeneration Study (Project)

This study investigates the relative distribution, health, and regeneration patterns of two major stands of sycamore alluvial woodland (SAW) in Santa Clara County, representing managed and natural settings.  Using an array of ecological and geomorphic field analyses, we, along with our partners at H.T. Harvey, discuss site characteristics favorable to SAW health and regeneration, make recommendations for restoration and management, and identify next steps.

Lower Walnut Creek Historical Ecology Study (Project)

During the mid-19th century, the lower Walnut Creek watershed was a landscape dominated by extensive wetlands, meandering creeks, and grassy plains. The marshes, sloughs, and meadows provided habitat and food for a huge number of wildlife species ranging from grizzly bears and elk to clapper rails and steelhead. Over the past 150 years, urban development, diking and filling of wetlands, and channelization of streams has resulted in dramatic changes to the watershed, and much of the historical habitat has been lost.

Lower Novato Creek Vision Just Released! (News)

SFEI recently released a resilient landscape vision for lower Novato Creek that incorporates habitat restoration actions into flood risk management. The vision, developed in coordination with a team of regional science experts, highlights opportunities for restoring and sustaining vital tidal wetland habitats around lower Novato Creek while supporting a high level of flood protection under rising San Francisco Bay water levels.
