SF Invasive Spartina Project

San Francisco Estuary Invasive Spartina Project

Hybrid Spartina rapidly colonized mudflats, such as these surrounding Alameda Island.

The Invasive Spartina Project is a coordinated regional effort among local, state and federal organizations dedicated to preserving California's extraordinary coastal biological resources through the elimination of introduced species of Spartina (cordgrass).

Introduced cordgrasses are highly aggressive invaders that significantly alter both the physical structure and biological composition of our tidal marshes, mudflats and creeks.
