From the report ….
“Underwater grasses provide significant benefits to aquatic life and serve many critical ecological functions in the Bay and its tributaries, such as:
Providing shelter for young striped bass, blue crabs and other species
Improving water clarity by helping suspended sediment particles settle to the bottom
Adding oxygen to the water
Reducing shoreline erosion
