Catalyzed by the extensive damages caused by the Winter 2016-2017 storms and the opportunity to align flood response with major habitat improvement, Preparing for the Storm is an innovative public-private partnership to improve watershed health and resilience in the Alameda Creek watershed.

SFEI is using bird observations from eBird to study habitat suitability and build occupancy models for California Quail to inform the Presidio Trust and other park managers how management interventions could help improve quail survival.

The Journal of Applied Ecology has just published research by Kelly Iknayan of the San Francisco Estuary Institute (SFEI) and co-authors from the Presidio Trust and SFEI that will help to guide a joint study on the feasibility of bringing back the native California quail to San Francisco. 

Erica Spotswood and a team of scientists published pioneering research in Nature Sustainability, finding that COVID-19 tracks neighborhood greenness in the US, exacerbating existing inequity. The study, titled “Nature inequity and higher COVID-19 case rates in less green neighbourhoods in the United States,” demonstrates a fundamental pattern that low-income and majority-minority communities systematically have less access to nature in urban areas across the U.S.

Nestled in the rugged coastal mountains between San Francisco and Silicon Valley lies one of the ecological treasures of the San Francisco Bay Area: the Peninsula Watershed. Home to mountain lions, marbled murrelets, towering old-growth Douglas-firs, and an immense diversity of other plants and animals, the Peninsula Watershed is a unique and wild expanse of open space just minutes from one of the most urbanized parts of California.

SFEI collaborates with the Google Ecology Program to advance the science and application of urban biodiversity and nature-based sustainability planning.

Cities will face many challenges over the coming decades, from adapting to a changing climate to accommodating rapid population growth. A related suite of challenges threatens global biodiversity, resulting in many species facing extinction. While urban planners and conservationists have long treated these issues as distinct, there is growing evidence that cities not only harbor a significant fraction of the world’s biodiversity, but also that they can also be made more livable and resilient for people, plants, and animals through nature-friendly urban design. 

Can we gain the benefits of restoring nature while making our cities denser and protecting natural and working lands?

This project is integrating research from the largely separate fields of urban ecology and public health to create design guidance that advances both ecological and human health in cities.

SFEI is working with partners across the Bay Area to design tools to help cities achieve biodiversity, stormwater, and climate benefits through multifunctional green infrastructure.

Two key reports support nature-based solutions. Green stormwater infrastructure (GSI) and enhancements to the urban tree canopy offer benefits to stormwater management, urban ecological improvements, and complementary urban greening activities.

On KGO TV, these projects were featured on July 1, 2021.

SFEI worked with local, state, and federal science experts to develop the new Sediment for Survival report. The report provides a regional sediment strategy aimed at examining the future of sediment in the Bay and informing sediment management for the resilience of tidal marshes and tidal flats to climate change.

The tidal marshes and tidal flats along the San Francisco Bay shoreline depend on sediment delivered by the tides. Healthy sediment supplies are essential for maintaining resilient marshes and tidal flats that can persist into the future and build up as sea level continues to rise. Currently, the sediment supply in the Bay is adequate to meet the sediment needed by tidal marshes and tidal flats. However, as sea level rise accelerates in the coming decades, the sediment needed for these habitats to survive will increase considerably.

Through the EPA-funded Healthy Watersheds Resilient Baylands project, SFEI and sixteen partner organizations are developing multi-benefit tools to enhance climate change resilience in San Francisco Bay. Healthy Watersheds Resilient Baylands has two major components: Multi-benefit Urban Greening and Tidal Wetlands Restoration. Through both components, we have developed strategies that inform  policy, planning, and design of innovative implementation projects.

Effective implementation of urban greening strategies is needed to address legacies of landscape change and environmental degradation, ongoing development pressures, and the urgency of the climate crisis. With limited space and resources, these challenges will not be met through single-issue or individual-sector management and planning. Increasingly, local governments, regulatory agencies, and other urban planning organizations in the San Francisco Bay Area are expanding upon the holistic, portfolio-based, and multi-benefit approaches.

SFEI is partnering with the City of East Palo Alto, the urban forestry non-profit Canopy, and HortScience | Bartlett Consulting to develop an Urban Forest Master Plan for the city.

Erica Spotswood and a team of scientists have established a new perspective on cities and nature, identifying the ways cities can contribute to regional biodiversity conservation. "The Biological Deserts Fallacy: Cities in Their Landscapes Contribute More than We Think to Regional Biodiversity" was published in the journal BioScience. Writer Eric Simons discusses the article in the Bay Nature story What a City Can Do for Nature.

SFEI collaborated with the International Union for the Conservation of Nature (IUCN) and the International Olympic Committee (IOC) to create a guide to incorporating nature into urban sports, from the development of Olympic cities to the design and management of the many sport fields throughout the urban landscape.

“Re-Oaking” is an approach to reintegrating oaks and other native trees within the developed California landscape to provide a range of ecosystem services. The concept has emerged from SFEI's research into the distribution and characteristics of California's former valley oak savannas -- a distinctive, widespread habitat that was mostly lost a century ago. Now valley oaks and other native trees are being recognized for the benefits they did -- and could again – provide, as communities design the ecologically healthy and resilient landscapes of the future.
