Brazilian Atlantic Islands: Fernando de Noronha and Atol das Rocas Reserves

Brazilian Atlantic Islands: Fernando de Noronha and Atol das Rocas Reserves

Peaks of the Southern Atlantic submarine ridge form the Fernando de Noronha Archipelago and Rocas Atoll off the coast of Brazil. They represent a large proportion of the island surface of the South Atlantic and their rich waters are extremely important for the breeding and feeding of tuna, shark, turtle and marine mammals. The islands are home to the largest concentration of tropical seabirds in the Western Atlantic. Baia de Golfinhos has an exceptional population of resident dolphin and at low tide the Rocas Atoll provides a spectacular seascape of lagoons and tidal pools teeming with fish.

Îles atlantiques brésiliennes : les Réserves de Fernando de Noronha et de l'atol das Rocas

Les sommets de la dorsale sous-marine de l’Atlantique Sud forment l’archipel de Fernando de Noronha et l’atoll das Rocas, au large des côtes brésiliennes. Ils représentent une grande partie de la superficie insulaire de l’Atlantique Sud et leurs eaux fécondes constituent des lieux de reproduction et de subsistance extrêmement importants pour les thons, requins, tortues et mammifères marins. Ces îles abritent la plus grande concentration d’oiseaux marins tropicaux de l’océan Atlantique Ouest. La baie de Golfinhos accueille une population exceptionnelle de dauphins résidents et, à marée basse, l’atoll das Rocas offre un paysage spectaculaire de lagons et de bassins de marée grouillants de poissons.

Бразильские острова в Атлантике: Фернанду-ди-Норонья и атолл Рокас

Архипелаг Фернанду-ди-Норонья и атолл Рокас, которые представляют собой выходящие на поверхность океана вершины подводного Южно-Атлантического хребта, лежат у восточных берегов Бразилии. Эти острова – одни из крупнейших в этом районе Атлантики, а их прибрежные воды отличаются высокой биопродуктивностью и играют исключительную роль в качестве мест обитания и размножения тунца, акул, морских черепах и морских млекопитающих. На островах отмечены самые крупные в Западной Атлантике скопления морских тропических птиц; также здесь сложилась большая местная популяция дельфинов. Во время отливов на атолле Рокас можно наблюдать впечатляющую картину: обмелевшие лагуны, кишащие рыбой.

Islas atlánticas brasileñas – Reservas de Fernando de Noronha y Atolón de las Rocas

Cimas de la gran dorsal submarina del Atlántico Sur que emerge frente a las costas de Brasil, el archipiélago de Fernando de Noronha y el Atolón de las Rocas representan una gran parte de la superficie insular de la región. Debido a sus aguas ricas en nutrientes, el sitio es de suma importancia para la alimentación y reproducción de atunes, tiburones, tortugas de mar y mamíferos marinos. Estas islas albergan la mayor concentración de aves marinas tropicales del Atlántico Occidental. La bahía de los Golfinhos es famosa por su excepcional población de delfines y, durante la marea baja, el Atolón de las Rocas ofrece un espectacular paisaje, salpicado de lagunas y pozas repletas de peces.

Braziliaanse Atlantische eilanden Fernando de Noronha en het reservaat Atol das Rocas

De pieken van de Zuid-Atlantische onderzeese bergkam vormen de Fernando de Noronha archipel en het Rocas atol voor de kust van Brazilië. Ze beslaan het grootste deel van het eilandoppervlak in de Zuid-Atlantische Oceaan. Hun rijke wateren zijn zeer belangrijk voor de voortplanting en het voedsel van tonijnen, haaien, schildpadden en zeezoogdieren. De eilanden vormen het leefgebied van de grootste concentratie tropische zeevogels in de West-Atlantische Oceaan. De baai van Golfinhos kent een uitzonderlijke populatie van lokale dolfijnen en bij eb verschijnt er bij het Rocas atol een spectaculair zeegezicht van lagunes en getijdenpoelen vol met vis.

Justification for Inscription

Criterion (ix): FNNMP/AdRBR represents over half the insular coastal waters of the Southern Atlantic Ocean. These highly productive waters provide feeding ground for species such as tuna, billfish, cetaceans, sharks, and marine turtles as they migrate to the Eastern Atlantic coast of Africa. An oasis of marine life in relatively barren, open ocean, the islands play a key role in the process of reproduction, dispersal and colonisation by marine organisms in the entire Tropical South Atlantic.

Criterion (vii): Baía dos Golfinhos is the only know place in the world with such a high population of resident dolphins and Atoll das Rocas demonstrates a spectacular seascape at low tide when the exposed reef surrounding shallow lagoons and tidal pools forms a natural aquarium. Both sites have also exceptional submarine landscapes that have been recognised worldwide by a number of specialised diving literatures.

Criterion (x): FNNMP/AdRBR is a key site for the protection of biodiversity and endangered species in the Southern Atlantic. Providing a large proportion of the insular habitat of the South Atlantic, the site is a repository for the maintenance of marine biodiversity at the ocean basin level. It is important for the conservation of endangered and threatened species of marine turtles, particularly the hawksbill turtle. The site accommodates the largest concentration of tropical seabirds to be found in the Western Atlantic Ocean, and is a Global Centre of Bird Endemism. The site also contains the only remaining sample of the Insular Atlantic Forest and the only oceanic mangrove in the South Atlantic region.

Long Description

Peaks of the Southern Atlantic submarine ridge form the Fernando de Noronha Archipelago and Rocas Atoll off the coast of Brazil. They represent a large proportion of the island surface of the South Atlantic and their rich waters are extremely important for the breeding and feeding of tuna, shark, turtle and marine mammals. The islands are home to the largest concentration of tropical seabirds in the Western Atlantic. Baia de Golfinhos has an exceptional population of resident dolphin and at low tide the Rocas Atoll provides a spectacular seascape of lagoons and tidal pools teeming with fish.

The Fernando de Noronha part of the site covers the majority of the main island and includes the majority of smaller offshore islands and islets. The Fernando de Noronha Archipelago and Rocas Atoll represent the peaks of a large submarine mountain system of volcanic origin, which rises from the ocean floor some 4,000 m in depth. The Fernando de Noronha volcano is estimated to be between 1.8 million and 12.3 million years old. The coastline is complex, with a number of high cliffs and sandy beaches. The north-west facing shores are relatively calm, whereas the south-east shores face the predominant currents and winds and are largely rocky shores with significant wave action.

The Rocas Atoll is a reef formation on a submarine mountain rock substrate, with an area of some 7.5 km2. During high tide only two sandy islands with a maximum height of 3 m above sea level and some isolated calcareous formations, the 'rocas', stand above water. Farol Island, the larger of the two, has a stretched 'S' form, with approximately 1,000 m in length and 200 m average width. During low tide the reef ring of the atoll is exposed, consisting of a natural wall some 1.5 m high and bordered by sandbanks. Inside the atoll is a large lagoon with shallows and pools 1-5 m deep.

The highly productive coastal waters around islands are used by many fish species for spawning and as a refuge for juvenile fish. The shallow waters also provide habitat for benthnic organisms (such as coral, sponges and algae). Oceanic islands therefore play a key role in the reproduction and dispersal of marine organisms, providing a staging point for the colonization of other coastal areas and the surrounding ocean. There are less than 10 oceanic islands in the South Atlantic and the Fernando de Noronha Archipelago and Rocas Atoll represent more than 50% of the islands in terms of surface area. As the site makes up such a large proportion of insular South Atlantic coastal area, it is an important repository for the maintenance of biodiversity for the entire South Atlantic basin.

Fernando de Noronha is also the only know location for Insular Atlantic Forest - a subtype of Atlantic Rainforest. To date over 400 species of vascular plants have recorded in FNNMP, including three endemics. FNNMP also contains the sole oceanic mangrove in the South Atlantic. The vegetation on Atoll das Orcas is mainly herbaceous, salt-resistant and typical of sandy beaches.
