Coral Sea Reserves Ramsar Site

The Coringa Islets and the Magdelaine and Herald Cays, as well as those of Lihou Reef, lie within the Coral Sea Reserves Ramsar Site

The Coral Sea Reserves Ramsar Site comprises the 17,292 km2 of oceanic island and reef habitats within the former Coringa-Herald National Nature Reserve and the former Lihou Reef National Nature Reserve in the Australian Coral Sea Islands Territory.

History

The existence of the islands and cays within the two reserves has been known to navigators since the early nineteenth century. Lihou Reef was named after Captain John Lihou of HMS Zenobia, who discovered the reef and its cays in 1823. The Coringa Islets were named after the cargo ship Coringa Packet, which foundered off Chilcott Islet in 1845. The Herald Cays were named after HMS Herald, which conducted hydrographic surveys in the Coral Sea, under the captaincy of Henry Mangles Denham, from 1849 to 1861.[1]

During the 1960s many of the islands and reefs in the Territory were visited by scientific survey parties. Following an assessment of the conservation status of the islands and reefs, and recommendations for the total protection of a sample of islands in the Coral Sea, eventually the two reserves were proclaimed on 16 August 1982. Since then many further surveys have been conducted, including a multi-disciplinary scientific expedition by the Royal Geographic Society of Queensland which visited the Herald Cays and their surrounding reef in 1997.[1]

The site was designated as a wetland of international importance under the Ramsar Convention on Wetlands. It was listed on 21 October 2002 as Ramsar Site 1222.[2]

Description

The site is centred on the Coral Sea Plateau, about 440 km east of Cairns, Queensland, and east of the Great Barrier Reef, from which it is separated by an area of deep water known as the Queensland Trough. Lihou Reef NNR lies to the south-east of the Coringa-Herald NNR and is separated from it by about 100 km of open sea.[1]

The key conservation values of the site, as listed in the reserves’ management plan are the:[1]

Flora and fauna

Several of the site’s 24 islets provide undisturbed sandy beach habitat for nesting green turtles, as well as forest and shrubland supporting breeding populations of terns and other seabirds. Its coral reefs support a distinct community of marine benthic plants and animals, a diverse decapod crustacean and hydroid fauna, and feeding habitat for migratory shorebirds and seabirds. Seaweed communities are also important.[2] There are no known native terrestrial mammals within the Reserves; introduced black rats were present on South West Coringa Islet for many years, but were eliminated by 1991 after an eradication program.[1]

Birds

The only breeding landbirds in the site are the purple swamphen and buff-banded rail. Among the 14 species of seabird recorded as breeding in the site are the lesser frigatebird, great frigatebird, red-footed booby, brown booby, masked booby, black noddy and red-tailed tropicbird.[1]

Access and usage

The large number of shipwrecks within the area give it marine archaeological significance. There is no resident human population; the site is used principally for nature conservation and scientific research. The reserves are internationally renowned for diving, snorkeling and bird watching. Access by commercial tour groups is regulated and limited, though there is some visitation by private yachts.[2]
