Historical ecology has formed the foundation of SFEI’s Resilient Landscapes Program since its inception. This interdisciplinary field synthesizes diverse historical records to learn how habitats were distributed and ecological functions were maintained within the native California landscape.
Given the dramatic changes to California landscapes during the past two centuries, we often have only rudimentary understanding of the systems we seek to protect and enhance. In fact, there is a growing recognition that restoration efforts have often misinterpreted earlier conditions, resulting in missed opportunities and, in some cases, failed projects. However, the development of accurate, reliable, and broadly-supported pictures of historical condition and change can help correctly identify the causes of current challenges, and reveal previously unrecognized management options. Understanding how streams, wetlands, and woodlands were organized along physical gradients helps scientists and managers develop new strategies for more integrated and functional landscape management. Historical reconstructions also educate and engage the public imagination, increasing public will for local and regional landscape stewardship.
SFEI's historical ecology studies have contributed to numerous restoration projects in the Bay Area and coastal California. Projects are carried out in collaboration with local partners and with a team of regional and local science advisers, with results made broadly available through website, publication, and presentation. SFEI's innovative approaches have been featured in New Scientist Magazine, Landscape Journal, The Living Landscape: An Ecological Approach to Landscape Planning, the McGraw-Hill Encyclopedia of Science and Technology, and the Historical Ecology Handbook, as well as general audience science programs such as KQED’s QUEST and the Saving the Bay documentary.

As sea levels continue to rise at an increasing rate, communities will need to adapt the California shoreline to create greater social, economic, and ecological resilience. Sea-level rise, together with high tides and storm surges, will impact roads, wastewater infrastructure, low-lying communities, and ecosystems in many of our region’s most vulnerable areas. Shoreline ecosystems provide multiple benefits such as habitat for wildlife, protection from storm surges, carbon sequestration, and recreation opportunities. With our Shoreline Resilience Focus Area, we continuously work toward the goal of maintaining and improving our natural and built shorelines while making them more resilient to climate change.
With a unique skill set of skills and relationships drawn from decades of working in the San Francisco Bay community, we bring together diverse stakeholders to arrive at science-based landscape-scale solutions for shoreline restoration, adaptation, and resilience. We bring expertise in geomorphology, wetlands ecology, sediment science, planning, and landscape design to make relevant scientific information available for decision-making. We develop regional-scale scientific studies, geospatial tools, and site-scale visions for shorelines across California, focusing on San Francisco Bay and Southern California wetlands. We partner with regional resource agencies, flood control districts, local governments, NGOs, community organizations, wastewater treatment plants, land trusts, and others to develop natural and nature-based strategies for shoreline adaptation with multiple co-benefits. We also serve as advisors to agencies on specific projects, governance decisions, and policy changes.

The Sacramento-San Joaquin Delta supplies freshwater to a large portion of California’s cities and agriculture, supports an agricultural economy and culture, and is home to native wildlife found nowhere else in the world. This complex region is hampered by many environmental challenges, including an over-allocated water supply, invasive species, water quality problems, novel ecosystems that no longer support desired functions, aging infrastructure, and a complex management structure. Beyond these challenges, sea level rise, other impacts from climate change, and earthquakes pose significant risks to Delta ecosystems, agriculture and water supply. The Delta Science and Management Focus Area investigates the ecology, hydrology and geomorphology of the Delta to inform decision making in this complex environment.
The three-part Delta Landscapes Project investigated the historical ecosystems of the Delta, examined how these ecosystems have been modified in the current landscape, and provided a holistic, aspirational approach to restoration. Building on this foundation, SFEI has contributed to multiple regional planning efforts and investigations of how the Delta supports specific functions, including primary production, salmon rearing habitat, and carbon storage. Our work from many of these projects is incorporated in the Delta Landscapes Scenario Planning Tool, a set of resources to assist users with developing, analyzing, and evaluating different land use scenarios to inform ongoing and future restoration planning efforts.

The Wetland Monitoring & Assessment Focus Area provides scientific and technological support for coordinated, collaborative, cost-effective wetland planning, management, assessment, and reporting across government policies and programs. Working with other Focus Areas at SFEI, and with many outside partners, we help all interests develop place-based goals for wetland protection by developing and implementing tools, such as Historical Ecology, the California Aquatic Resource Inventory (CARI), and the California Rapid Assessment Method for wetlands (CRAM) to understand how the abundance, diversity, and condition of wetlands have changed due to nature and people, and to explore alternative ways to protect and restore wetlands for the future.
Products of the WMA Focus Area are designed for consistent adoption into wetland regulatory and management procedures at all levels of government, to promote coordinated, consensus-based, scientifically sound wetland and stream restoration and protection. Products include WRAMP, the state wetland definition and delineation method, California Aquatic Resource Inventory (CARI) and its eco-regional versions, Habitat Project Tracker, the Riparian Zone Estimator Tool (RipZET), the California Rapid Assessment Method for wetlands and streams (CRAM), Landscape Profile Tool, Green Plan-IT for large scale restoration planning, and the Science Frameworks for the Russian River Regional Monitoring Program (R3MP) and the Bay-Delta Wetlands Regional Monitoring Program (Wetlands RMP).
The WMA POD features projects that integrate all of these products into quantitative watershed-based assessments of wetland and riparian abundance, diversity, distribution and condition that are accessible through EcoAtlas to support a watershed approach to aquatic resource restoration and protection. Example assessments have been produced for the Upper Truckee River (Alpine Co), Santa Clara County watersheds, Wildcat Creek (Alameda Co), Napa River (Napa Co), and Mark West Creek (Sonoma Co). WMA personnel serve on many regional, state, and national committees to advise wetland policies, programs, and projects.

The Watershed Science and Management Focus Area investigates physical and ecological processes to help develop resilient landscape management approaches for watershed ecosystems. With expertise in geomorphology, hydrology, and ecology, the Watershed Science and Management Focus Area uses a variety of analytical tools to provide an understanding of historical, contemporary, and projected future watershed processes and landscape evolution at a range of spatial and temporal scales. This understanding is used to help managers determine landscape sensitivity to natural and anthropogenic influences, identify short-term and long-term management priorities, and develop multi-benefit solutions for habitat restoration that account for changing climatic and land use conditions.
The Watershed Science and Management Focus Area is currently working with partners around the San Francisco Bay region and the state of California on the following efforts:
- Developing watershed-scale management visions that identify opportunities for ecosystem improvement
- Conducting focused field investigations of hillslope and channel physical and ecological processes
- Investigating physical drivers for in-channel and riparian ecological condition
- Assessing the potential impacts of climate change on future watershed conditions and sediment delivery
- Developing innovative approaches for urban green infrastructure that provides multiple hydrologic and ecological benefits

With over a million acres of protected land and a strong agricultural heritage, the San Francisco Bay Area is home to a unique mosaic of open space and working lands. This landscape offers multiple benefits to local ecosystems and Bay Area communities, with shared uses spanning biodiversity conservation, water resource protection, recreation, and agriculture. Terrestrial Ecology at SFEI supports natural resource management in these open spaces, drawing from ecosystem ecology, spatial ecology, and community ecology. Using best-available science, we help land managers make ecologically-informed decisions around management goals such as biodiversity conservation, carbon sequestration, and fire risk management.
Terrestrial Ecology at SFEI brings expertise in biogeochemistry, landscape ecology, community ecology, and geospatial analysis to projects in the Bay Area and beyond. In partnership with natural resource agencies, land trusts, and other land managers, we leverage this expertise to evaluate co-benefits and tradeoffs among ecosystem services, and to identify opportunities for improved land stewardship. Our work spans quantitative and qualitative data analysis through synthesis, modeling, and field-based research, and we collaborate with scientific advisors from local universities, agencies, and research institutes to integrate science across multiple disciplines and management priorities. Collaborating with other SFEI focus areas such as Historical Ecology and the Urban Nature Lab, Terrestrial Ecology at SFEI offers scientific and locally-specific guidance for healthy and resilient parklands, agricultural lands, and wildlands.

The Urban Nature Lab at SFEI uses the quantitative science of nature in cities to guide innovative, ecologically-based urban planning and design. The Lab responds to the growing interest among planners, designers, policy-makers, and the public in gaining the diverse benefits nature can provide to urban communities, and the need for science-based design tools that draw from interdisciplinary research on cities. We bring together expertise in data science, ecology, ecosystem services, landscape architecture, and urban planning to create accessible, actionable guidance that makes the best available science available to those who need it.
The Urban Nature Lab helps cities create and support well-designed networks of nature that provide the critical functions we need from nature in our cities: reducing extreme heat, attenuating and purifying stormwater, improving physical and mental health, providing equitable access to nature and its benefits, and supporting local and regional biodiversity. We perform advanced data science analyses of land use, citizen science, health, census, and other data; synthesize emerging research from diverse fields; and collaborate with teams of design professionals to incorporate nature into projects, plans, and policies. We work closely through partnerships in the San Francisco Bay Area and around the world to advance the tools needed to create the healthy and resilient cities of the future.
