La Cordillera Reef Nature Reserve
The La Cordillera Reef Nature Reserve (Spanish: Reserva Natural Arrecifes de la Cordillera), also known as the Reserva Natural Cayos de la Cordillera (Cordillera Cay Nature Reserve), is a nature reserve located 1.5 nautical miles off the coast of the barrio of Cabezas in the municipality of Fajardo in northeastern Puerto Rico. It consists of a small chain of cays, reefs, and islets, collectively known as La Cordillera (''the mountain range'') or Cayos de la Cordillera (Cordillera Cays). From west to east, the archipelago comprises Las Cucarachas islets, Los Farallones islets, Icacos cay, Ratones cay, Lobos cay, Palominos island, Palominitos island, La Blanquilla cay and islets, Diablo cay, Hermanos reefs, and Barriles reefs. The nature reserve covers about 18 nautical miles and almost 30,000 acres between cape Las Cabezas de San Juan in Cabezas, Fajardo and the Spanish virgin island of Culebra.[1][2][3] With the exception of Palominos island and Lobos cay, which are privately owned, all cays, reefs, and islets in the small chain are protected by the marine reserve. The total land area of the reserve is 218 acres. The nature reserve is also important for local fishermen and eastern coastal municipalities, including Fajardo, Ceiba, and Naguabo, which depend on the reserve for their fishing industries.[4][5] Although occasionally included as part of the reserve, the cays and reefs outside the chain that lie immediately next and parallel to the main coastline of Puerto Rico in Fajardo and Ceiba are not strictly protected by the reserve. From north to south, these are: Obispo cay, Zancudo cay, Roncador reef, Mata Caballos reef, Corona Carrillo reef, Ahogado cay, Ramos island, Largo cay, Piñeros island, Cabeza de Perro cay, Piñerito cay, Cabritas cay, and Cabras island.  HistoryBefore its preservation, Icacos cay was important for the extraction of limestone for use in the sugarcane industry and construction in Puerto Rico. The conservation area that today encompasses the Cordillera Reef Nature Reserve was first designated on January 2, 1980, by the Coastal Zone Management Plan (Spanish: Plan de Manejo de la Zona Costanera) with the goal of preserving the coral reefs and marine habitats surrounding the Cordillera Cays, a small reef archipelago consisting of cays such as Icacos cay, Ratones cay, Lobos cay, La Blanquilla reef, Diablo cay, and Palomino island. Other protected areas include Los Farallones, Barriles, and Hermanos reefs.[5] Administration over the nature reserve was transferred to the Puerto Rico Department of Natural and Environmental Resources (DRNA) in 1991. Management plans included the preservation of important bird nesting areas in some of the keys and the establishment of a marine wildlife refuge for the protection of endangered species such as green sea turtles and West Indian manatees.[5][6] The reserve is considered today a prime eco-tourist destination where visitors can swim along coral reefs and visit the beaches located in some of the cays, particularly Icacos.[7] EcologySome of the marine ecosystems found within the reserve are coral reefs, sandy seashores, and extensive seagrass prairies which are important for sea turtles and manatees. La Cordillera Reef is also one of the largest preserved coral areas in the territory of Puerto Rico; the reefs are of high importance due to their high coverage of living coral. The three types of coral reef found in the reserve are rocky reef, consisting of coral growing on aeolianite and cemented sand, barrier reef, consisting of coral growing along keys and coastlines, and patch reef, consisting of patches of coral colonies growing on sandy seafloor. Some of the most common types of coral found in the area are Montastraea, Diploria, Acropora, Colpophyllia and Porites.[4][6] FaunaThere are more than 83 documented fish species in the reserve, 33 of which are of importance for the regional fishing industry. The spiny lobster (Panulirus argus) and the queen conch (Strombus gigas) are also important species for fishing. The reserve also sustains keystone species that are responsible for important ecological processes such as "reef cleaning" which allows for the settlement, development and growth of new coral polyps; one of these keystone species is the black urchin (Diadema antillarum). In addition to the submerged fauna, this reserve is an important bird area with species such as the brown noddy (Anous stolidus), the bridled tern (Sterna anaethetus), the sooty tern (Sterna fuscata), the brown booby (Sula leucogaster), the laughing gull (Larus atricilla) and the roseate tern (Sterna dougalli), all of which are protected on the territorial and federal level. Humpback whales are also common throughout the winter months of December, January and February.[6] FloraThe most important flora in the reserve is the seagrass Thalassia testudinum and Syringodium filiforme, which form important seagrass prairies that sustain many marine species such as turtles and manatees. This ecosystem sustains one of the largest manatee populations in the archipelago of Puerto Rico.[6][8] See alsoReferences
