New Caledonia creates a huge shark sanctuary

Pew Trust congratulates New Caledonia for creating a shark sanctuary


April 2013. New Caledonia has created a vast 1,245,000 square kilometres (480,000 square miles) shark sanctuary giving comprehensive and permanent shark protection in an area roughly the size of South Africa. The ocean around New Caledonia is still considered healthy and intact, and home to spectacular marine life, including approximately 50 species of sharks.

Several shark sanctuaries have been launched recently
Josh Reichert, executive vice president of The Pew Charitable Trusts said "We applaud New Caledonia's decision to create a shark sanctuary by banning fishing for all shark species in the country's entire exclusive economic zone . In the past few months alone, French Polynesia, the Cook Islands, American Samoa, and the Micronesian state of Kosrae have ended shark fishing in their waters.

CITES
"In March 2013, 177 countries voted to protect oceanic white tip sharks, porbeagle sharks and three types of hammerhead sharks at the meeting of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Though great progress is being made, sharks are still threatened throughout much of the world's oceans. The finding of a recent scientific study that approximately 100 million sharks are killed each year in commercial fisheries represents an urgent call to governments around the world to take action before it's too late. Scientists warn that the rate of fishing for sharks, many of which grow slowly and reproduce late in life, is unsustainable and could lead to the extinction of many species. 

"The role of sharks is critical to the health of marine systems. One third of shark species are currently threatened or near threatened with extinction, according to the International Union for Conservation of Nature. There is an immediate need to protect them before they slip below levels from which they may never recover. It's now up to countries to build on this recent success and ensure a promising future for sharks."

Rat eradication success in New Caledonia

September 2011. As part of a David and Lucile Packard Foundation project Société Calédonienne d'Ornithologie (SCO) the BirdLife Partner in New Caledonia, undertook operations in 2008 to eradicate invasive Black Rats and Pacific Rat from three important seabird islands in New Caledonia. The latest follow up surveys has confirmed that Table, Double and Tiam'bouène islands are all officially rat-free, and the bird populations are already showing signs of recovery.

The islands of Table (14 ha), Double ( 6 ha) and Tiam'bouène (17 ha) form part of the Îlots du Nord-Ouest Important Bird Areas (IBA) complex in Northwest New Caledonia. They are globally important for Wedge-tailed Shearwater Puffinus pacificus, Roseate Tern, Fairy Tern, Dark-brown Honeyeater and Green-backed White-eye which were being predated by introduced rats.

In September 2008 SCO completed operations to remove rats from the three islands, and the most recent follow up survey in mid-July 2011 has formally declared these operations successful following 24 months of rat-free monitoring.

Bird numbers recovering & new birds breeding
Already bird populations are showing signs of recovery, and [Vulnerable] Fairy Tern nested on the islands for the first time in 2010; Tiam'bouène hosting a colony of 28 active nests. Another very encouraging result is the first ever presence of [Near Threatened] Tahiti Petrel which was found breeding on Table Island in July 2011.

On each island, along with many new bird species being recorded, SCO report that the eco-systems are also showing positive signs of recovery. SCO are grateful for the support received from several individuals and organizations in completing these eradications and in particular thank the Pacific Invasives Initiative, the New Zealand Department of Conservation, and BirdLife International for their assistance.

The removal of rats on these islands is therefore an important starting point for the management of IBA islands Northwest. It is also an important action for the conservation of Fairy Tern in New Caledonia with between 70 and 90 pairs now found in the IBA out of a total of 130 pairs in the country.

Next steps are to continue monitoring the biodiversity recovery of the islands, seek the creation of nature reserves to protect the tern colonies from human disturbance, and to expand rat eradication to additional islands included within the IBAs complex.
