Coral and seagrass beds

The Réserve Naturelle of Saint Martin does a scientific study of the ocean’s depths since 2007.
Each year, they make a repertory of all coral less than two centimeters, count and measure conch and sea urchins, inventory underwater plants, and verify the layers covering of the substratum. Underwater plant beds provide a nursery for numerous species and offer them protection and food.
These plants represent a fragile, endangered ecosystem, that plays a determining role in the purification of coastal waters.
