Join us for a lunch webinar on March 20th, 2024, where Vanessa Lee (Associate Environmental Scientist), Karen Verpeet (Resilient Landscapes Program Managing Director), and Kelly Iknayan (Senior Scientist) will speak to members of the ASLA Northern CA Chapter about research, strategies, and projects at the intersection of science and landscape architecture.

The largest brackish marsh on the West Coast, Suisun Marsh is a unique transitional landscape between San Francisco Bay and the Sacramento-San Joaquin Delta. The Marsh supports high ecological diversity and has long been managed for recreational hunting and native species support, yet it is threatened by an uncertain future under climate change. Effective adaptation in Suisun will require coordinated, science-based planning by agencies and private landowners.

The same features in urban parks that support biodiversity can also benefit human health. Even biodiversity itself may help us — and the San Francisco Estuary Institute (SFEI) wants to see more of it. To that end, the nonprofit released an innovative report in September called Ecology for Health. It’s a practical guide for planners and designers to aid both biodiversity and human health in urban settings.

The Ecology for Health guide is based on an extensive review of ecological literature on the potential of cities to support native plants and wildlife, as well as research exploring the health benefits of access to biodiverse greenspace. Anyone making decisions about land use and urban design in cities across the world can benefit from the recommendations in this guide (including community-based organizations, local non-profits, local leaders and policymakers, city planners, urban designers, landscape architects, engineers, gardeners/horticulturists/arborists, residents, and landowners). 

In partnership with the Delta Stewardship Council, the San Francisco Estuary Institute has developed version 2.0 of the Landscape Scenario Planning Tool, a GIS-based analysis toolkit to evaluate user-designed land use and restoration scenarios for the Sacramento-San Joaquin Delta and Suisun Marsh. This free mapping toolbox brings together ten years of science-based research and peer-reviewed methods for California’s Delta-Suisun region. 

As the largest brackish marsh on the West Coast, Suisun Marsh is a unique transitional landscape between the Bay and the Delta portions of the Estuary. The Marsh has long been managed for recreational hunting and native biodiversity, yet it is threatened by an uncertain future under climate change. Sea level rise and increasing salinity pose significant threats to the current structure and uses of the Marsh. Likely impacts include conversion of wetlands to open water, changes in species composition, increased flood risk, and drainage challenges in managed wetlands.
