From the site ChesapeakeBay.net:
"The tidal marshes of the Chesapeake Bay's shallows are border habitats that connect shorelines to forests and wetlands. Just like wetlands and underwater bay grass beds, tidal marshes provide food and shelter for the vast array of fish, birds, invertebrates and other animals that dwell in shallow waters.
There are three types of tidal marshes found along the Chesapeake Bay:
- Freshwater marshes of the upper Bay
- Brackish marshes of the middle Bay
- Salt marshes of the lower Bay
Salt marshes are wetlands dominated by cordgrass, also called Spartina. They are one of the most productive plant communities on earth. Salt marshes are located above and below the high tide line.
- Low marshes are regularly flooded by the tides. The tall form of smooth cordgrass grows here. Low marshes provide critical habitat for juvenile fish, as well as shrimps, fiddler crabs, marsh crabs, marsh periwinkles and ribbed mussels.
- High marshes are irregularly flooded by strong winds or exceptionally high tides. Three-squares, saltmeadow cordgrass and the short form of smooth cordgrass grow here."
I've always referred to it as marsh grass. Spartina? Really?
