Eelgrass once grew in abundance in Barnegat Bay, New Jersey, where it was harvested, dried and used for insulation in houses, such as the governor's summer mansion in Island Beach State Park. A blight decimated the eelgrass, which ended harvesting of the plant. The plant is making a gradual comeback.
Seagrasses grow in salty and brackish (semi-salty) waters around the world, typically along gently sloping, protected coastlines. Because they depend on light for photosynthesis, they are most commonly found in shallow depths where light levels are high. Many seagrass species live in depths of 3 to 9 feet (1 to 3 meters), but the deepest growing seagrass (Halophila decipiens) has been found at depths of 190 feet (58 meters).
