Parque Nacional del Este (Cotubinama)

The marine portions of Cotubinama are among the most ecologically important in the Dominican Republic:

• Coral reefs: The park protects extensive barrier and fringing reef systems with over 50 species of hard coral and abundant soft corals and sponges.
• Manatees: The West Indian manatee, an endangered species, inhabits the park's coastal waters. While sightings are rare, their presence indicates a healthy marine ecosystem.
• Sea turtles: Hawksbill and green sea turtles nest on the park's beaches and are regularly seen while snorkeling and diving.
• Seagrass beds: Extensive underwater meadows serve as nursery habitat for fish and feeding grounds for turtles and manatees.

Conservation challenges include managing the enormous tourism pressure (particularly on Isla Saona), controlling illegal fishing, and protecting nesting beaches. Visitors can support conservation by choosing responsible tour operators, not touching coral or marine life, and respecting the park's regulations.
