The park is comprised of 316,160 acres of marine and coastal habitat along the mainland and around the Islands of Salango and La Plata; the surrounding ocean encompasses Ecuador's only continental coral reefs. The park’s marine boundaries protect 40 percent of coastal fisheries in the country. La Plata Island is a major feeding ground for several shore birds, including pelicans, frigate birds, and boobies and protects the only known population of waved albatross outside of the Galapagos Islands. Humpback whales also breed within park boundaries. The park is also known for its tropical dry forest, fog forest, coastal scrub, islands and islets.
