Mapping Seagrass
Habitats on Two Coasts
Just as plants, water, and the sun are vital to sustaining human life, seagrass found in estuaries helps marine life flourish.
Seagrass is a rooted, aquatic plant that provides food, habitat, and nursery areas for numerous vertebrate and invertebrate
species. Seagrass distribution and extent is a very good barometer of the health and water quality of estuarine systems.
Seagrass habitats have been on a sharp decline around
