Eelgrass is a bay grass with long, ribbon-like leaves. It grows in the saltier waters of the middle and lower Chesapeake Bay.
Eelgrass is made up of long, ribbon-like leaves that can grow to 4 feet long, but vary in size depending on the plant’s location. A wide, tube-shaped sheath is at the base of each leaf. Eelgrass has thick, creeping rhizomes with many roots and nodes.
Grows in salty tidal waters of medium to high salinity. Usually found in shallow, sandy areas and occasionally found in deep, muddy areas.
Ranges from the Honga River on Maryland’s Eastern Shore south to the mouth of the Chesapeake Bay. Eelgrass and widgeon grass are the dominant bay grass species in the Virginia portion of the Bay.
Migratory waterfowl such as brants, redheads, widgeons, black ducks and Canada geese feed on eelgrass, as do green turtles. Although they do not feed on eelgrass, cownose rays destroy eelgrass beds in many areas as they root through bottom sediments for their prey.
Asexual reproduction takes place when the rhizome grows and winter buds called turions form. Sexual reproduction takes place in early summer, when female flowers are fertilized by drifting pollen and develop into seed-bearing shoots. The shoots eventually break off, float to the surface and release their seeds.
