Action 13: Seasonal Wetlands
← Back to Estuary Blueprint Actions
Protect, restore, and enhance seasonal wetlands.
Protect, restore, and enhance non-tidal seasonal wetlands outside of historical tidal areas, including vernal pool complexes, using conservation easements and related protection tools, restoration, and improved grazing management practices.

Overview

Seasonal wetlands can be found upland and are called “seasonal” because they periodically flood or fill with rain, runoff, or groundwater during winter rains. Their salinities lie on a spectrum of salty to fresh, since many seasonal wetlands may be former tidal marshes that have been closed off from tidal action by dikes and levees. Seasonal wetlands also provide habitat for large numbers of waterfowl and shorebirds during migratory periods and support rare and endangered plants and invertebrates.

Task Description

Protect non-tidal seasonal wetlands including vernal pool complexes using conservation easements or other protection tools.

Updates and Emerging Issues

Since 2016, this Action’s Tasks have been expanded to cover seasonal wetlands more generally: not just vernal pool complexes. Also, this Action’s protection and restoration Tasks are now aligned with the goals of The Conservation Lands Network 2.0 Report and San Francisco Bay Joint Venture. Looking ahead to the next Estuary Blueprint revision, this Action is expected to explore more opportunities to partner with landowners around grazing management and forest management best practices.

Climate Change Considerations

Climate change will bring more extreme and unpredictable weather to the region. Extended dry periods and prolonged or extreme flooding may result in the increased precariousness of seasonal wetlands.

Equity Considerations

Like other habitat-oriented Actions, projects to restore seasonal wetlands should engage Tribes and frontline communities in planning and implementation. Tasks under the Climate Resilience and Equity Actions address this need.
