Tidal Wetland Project: Marsh Loss and Habitat Erosion

the Tidal Wetland Project.

Fifty percent, or 1,000 acres, of Elkhorn Slough’s salt marshes have been lost over the past 150 years due to human actions. Marsh loss and estuarine habitat erosion in Elkhorn Slough is currently ongoing with channel bank erosion rates from 1 to 2 feet per year and interior marsh dieback rates of at least 3 acres per year. These rapid changes not only affect the estuary’s animals and plants, but also impact public access sites and railroad and road infrastructure. In addition, Elkhorn Slough’s estuarine habitats suffer from subsidence, degraded water quality conditions, and invasion of non-native species.
