 The plants that grow in the shallow waters of the Chesapeake Bay and its rivers, streams, and creeks are a critical part of the Chesapeake Bay ecosystem. Known as underwater grasses or submerged aquatic vegetation (SAV), these underwater grasses improve water quality by reducing erosion, trapping loose sediment and absorbing nutrient pollution. During photosynthesis, the plants ass the dissolved oxygen to the water that underwater critters need to survive. They also serve as a habitat for young fish and crabs to provide food for migrating waterfowl, such as ducks and geese.
