The South Bay Salt Pond Restoration Project covers 15,100 acres of historically tidal wetlands in southern San Francisco Bay. 85% of the wetlands were lost due to industrial salt production. This project is restoring the wetlands to tidal marsh to reduce flooding, protect infrastructure, provide recreation opportunities, among other benefits.

Nature-Based Solutions Case Study Search
This database contains over 400 implementations of nature-based solutions. Use the filters to identify the case studies most relevant to you.
While all cases here exemplify applications of NBS strategies, they were gathered from various sources and not all were written using the framing of nature-based solutions. To qualify as a nature-based solution, a project must provide benefits to both people and nature. In some instances, the human benefits are present but not emphasized in the case write ups; these cases were included because they still provide useful information to learn from.

The Karuk Tribe of California and the Six Rivers and Klamath National Forests worked on developing a programmatic approach to watershed restoration in the Karuk Ancestral Territory, an area that was degraded by past mining, excessive logging, and road building activities.
To protect native aquatic species, National Park Service (NPS) biologists have conducted bullfrog control in Yosemite Valley since the 1990s. Bullfrog removal continued regularly through 2015, with successful eradication achieved in 2019. Bullfrogs were removed using mechanical techniques such as backpack electrofishing, dip and seine nets, hook and line, and rifle shooting.
Napa County has experienced flash floods that resulted in deaths and hundreds of millions of dollars in damages. Napa and surrounding counties opted for a restorative flood mitigation approach to address environmental issues while increasing flood resiliency. The project design aimed to return the river to its natural state to prevent flooding.
Levees and dams within California’s Central Valley have diminished crucial fish habitat, causing a decrease in native salmonid populations. The Big Notch Project reconnected the floodplain habitat and improved the fish passage by cutting “notch” into the Fremont Weir and install a new gated headworks structure.
