Seagrass beds are shallow coastal ecosystems dominated by rooted, flowering marine plants adapted to saline, underwater environments. In Costa Rica, they are mostly found in calm, shallow waters along the Caribbean coast and in some Pacific bays such as Golfo Dulce. These ecosystems play a crucial role in stabilizing sediments, cycling nutrients, and supporting diverse marine life. They provide essential nursery grounds for fish and invertebrates, feeding areas for sea turtles and manatees, and contribute significantly to carbon sequestration in marine environments.
Protected Areas:
Gandoca–Manzanillo Wildlife Refuge
Cahuita National Park
Golfo Dulce Marine Area
Ramsar sites associated with coastal wetlands
February to April (dry season ensures better visibility and lower turbidity)
Seagrass beds are blue carbon ecosystems, storing more carbon per hectare than tropical forests. They are essential for the survival of juvenile marine life and as grazing zones for iconic species. Conservation of these habitats is linked closely to the health of coral reefs, mangroves, and local fisheries.
