San Francisco Bay is more than a defining geographic feature: it is home to hundreds of types of fish, birds, and other wildlife, and provides food and shelter to abundant resident and visiting wildlife. Many are unaware that the Bay, the largest estuary on the west coast of North America, is in a league with Chesapeake Bay on the east coast and the Mississippi Delta on the gulf coast. While humans appreciate its beauty and presence, millions of birds use the Bay as a critical stopover point on their migration along the Pacific Flyway each year, finding  food and shelter in the saltmarshes and tidal mudflats. But these places are under threat, not just from sea level rise but also from invasive plants. In the 1970s, well-meaning engineers planted Atlantic cordgrass (Spartina alterniflora) for erosion control. Unfortunately, it began to spread, displacing the native vegetation, and altering vegetation communities. Since 2005, the Coastal Conservancy’s Invasive Spartina Project has used airboats, genetic testing, sophisticated GIS, and a lot of hard work to push back the invasive cordgrass. Learn about how hometown heroes are doing their part to address the global biodiversity crisis.
