ACE Basin
The ACE Basin NERR, designated in 1992, consists of about 140,000 acres and is one of 27 national reserves located along the US coastline. The National Estuarine Research Reserve System (NERRS) is a network of federal, state, and local partnerships that emphasize resource stewardship, monitoring of estuarine conditions, management-oriented research, technical information transfer, and environmental education.
It is ironic that while Spartina alterniflora, is valued in East Coast marshes, in West Coast marshes it is considered a noxious, invasive species because it converts valued mudflat areas into marsh; it is a “weed” that is smothering San Francisco Bay’s mudflats.
