What are the roles of bay grasses?
What are the roles of bay grasses?
Bay grasses serve many important ecological roles such as improving water quality, providing food and shelter for other species as well as stabilizing sediment at the bottom of the water column.
Why are SAV or underwater grasses so important for the Bay?
Underwater grasses are a critical part of the Bay ecosystem: they provide wildlife with food and habitat, add oxygen to the water, absorb nutrient pollution, trap sediment and reduce erosion.
What are Bay grasses also known as?
The Bay grasses, also known as submerged aquatic vegetation (SAV), provide several benefits for the Bay, including providing habitat for Bay animals, providing oxygen and reducing turbidity in the water column, and reducing erosion along the Bay’s shorelines.
Is there grass underwater?
There are more than a dozen varieties of underwater grasses, also called submerged aquatic vegetation or SAV, that grow in shallow water regions of the Bay and its rivers. At its most pristine, the Bay may have supported several hundred thousand acres of underwater grasses.
What do underwater grasses do?
Underwater grasses not only provide critical habitat for critters, they also protect shorelines from erosion, improve water clarity, and can even help reduce the effects of climate change. Underwater grasses are a critical habitat in the Bay and its tidal rivers.
Why are Sav submerged aquatic vegetation important to the wetlands?
Submerged aquatic vegetation is one of the most productive fish habitats on earth. SAV is a great habitat for fish, including commercially important species, because it provides them with a place to hide from predators and it hosts a buffet of small invertebrates and other prey.
What is grass that grows in water called?
Known as underwater grasses or submerged aquatic vegetation (SAV), they improve water quality by reducing erosion, trapping loose sediment and absorbing nutrient pollution.
What kind of grass grows underwater?
Widgeon Grass Like eelgrass, it is one of the dominant underwater grass species found in the Virginia portion of the Bay. Widgeon grass is also known as ditch grass, because it sometimes grows on land in the ditches alongside roads and farm fields.
What is the scientific name for underwater grass?
Description. Zosteraceae. The family Zosteraceae, also known as the seagrass family, includes two genera containing 14 marine species. It is found in temperate and subtropical coastal waters, with the highest diversity located around Korea and Japan.
What is the habitat of underwater plants?
Most aquatic plants live in freshwater—in lakes, ponds, reservoirs, canals, or rivers and streams. These habitats are very different in water depth, flow rates, temperature, acidity and alkalinity (pH ), and mineral content.
