Grevillea exul is a species of flowering plant in the family Proteaceae, endemic to New Caledonia. [2]
It grows up to 10 metres in height and has narrow lanceolate to elliptic leaves which have a blunt apex. [2] The flowers are usually white, followed by follicles which are 12–20 mm (0.47–0.79 in) long and 9–15 mm (0.35–0.59 in) in width. [2] It is a manganese accumulator. [3]
New Caledonia is a sui generis collectivity of overseas France in the southwest Pacific Ocean, south of Vanuatu, about 1,210 km (750 mi) east of Australia, and 17,000 km (11,000 mi) from Metropolitan France. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre le Caillou, a nickname also used more generally for the entire New Caledonia. Pro-independence Kanak parties use the name (la) Kanaky to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indigenous Melanesian Kanak people who make up 41% of New Caledonia's population. New Caledonia is one of the European Union's Overseas Countries and Territories (OCTs), but it is not part of the European Union.
The geography of New Caledonia (Nouvelle-Calédonie), an overseas collectivity of France located in the subregion of Melanesia, makes the continental island group unique in the southwest Pacific. Among other things, the island chain has played a role in preserving unique biological lineages from the Mesozoic. It served as a waystation in the expansion of the predecessors of the Polynesians, the Lapita culture. Under the Free French it was a vital naval base for Allied Forces during the War in the Pacific.
New Caledonia is a major source for nickel and contains roughly 10% of the world's known nickel supply. The islands contain about 7,100,000 tonnes of nickel. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the world's fifth largest producer after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000). In recent years, the economy has suffered because of depressed international demand for nickel due to the 2007-2008 global financial crisis. Only a negligible amount of the land is suitable for cultivation, and food accounts for about 20% of imports. In addition to nickel, the substantial financial support from France and tourism are keys to the health of the economy. In the 2000s, large additions were made to nickel mining capacity. The Goro Nickel Plant is expected to be one of the largest nickel producing plants on Earth. This plant produces an estimated 20% of the global nickel supply. However, the need to respond to environmental concerns over the country's globally recognized ecological heritage, may increasingly need to be factored into capitalization of mining operations.
Nouméa is the capital and largest city of the French special collectivity of New Caledonia and is also the largest francophone city in Oceania. It is situated on a peninsula in the south of New Caledonia's main island, Grande Terre, and is home to the majority of the island's European, Polynesian, Indonesian, and Vietnamese populations, as well as many Melanesians, Ni-Vanuatu and Kanaks who work in one of the South Pacific's most industrialised cities. The city lies on a protected deepwater harbour that serves as the chief port for New Caledonia.
