Invasive Species | FY23-24 $498,500

The National Park Service (NPS) will reconnect and restore tidal marsh to provide access and enhance quality of federally listed salmon rearing habitat in the lower Columbia River estuary and San Francisco Bay area parks.

Why? Past marsh development has dramatically shifted the historically clear fish passage and habitat to unpassable, degraded, hydrologically isolated spaces. By removing invasive plants, removing levees and reconnecting channels, this project will restore the historic marsh conditions that support threatened and endangered salmon and other species.

What Else? Region staff will measure the number of fish passages created, number of acres restored, number of salmon using the areas, and the increase in native plant coverage over time.

Bipartisan Infrastructure Law – Ecosystem Restoration

The Bipartisan Infrastructure Law makes critical investments in the resilience and restoration of America’s lands, skies, and waters, and enhances conservation and recreation opportunities. Visitors will see tangible results such as repaired and upgraded trails and campgrounds, removal of invasive species, as well as healthy wetlands, grasslands, and forests.
