Bay grasses are an important part of the Chesapeake Bay ecosystem. Not only do bay grasses improve water quality, they also provide food and shelter for waterfowl, fish and shellfish. For example, research has shown that the density of juvenile blue crabs is 30 times greater in grass beds than in unvegetated areas of the Bay! There are approximately 20 species of Bay Grasses that can be found in Maryland Bays and Tributaries.
