Why are SAV or underwater grasses important for the Bay?
SAV, or submerged aquatic vegetation (underwater grasses) are important to the Chesapeake Bay for many reasons. They provide shelter from predators for young crabs and fish that can’t really protect themselves. They provide food for lots of different species of waterfowl. They produce oxygen that the fish need to survive. And they help prevent erosion, because their roots hold soil together so that it doesn’t wash away.
