North Solomon Islands between Bougainville (an autonomous region of Papua New Guinea) and the sovereign state of Solomon Islands, which is the successor state to the British Solomon Islands Protectorate renamed in 1975 prior to achieving independence in 1976. On 17 February 1568, the archipelago was discovered by Spanish explorer Alvaro de Mendaña y Neyra, who named its "Islas de Salomon". In April 1885 a German protectorate ("Schutzgebiet") was declared over the northern Solomon Islands: Bougainville, Buka, Choiseul, Santa Isabel and Ontong Java. In 1893 the British declared a protectorate over the southern Solomon Islands of New Georgia, Guadalcanal, Malaita and San Cristobal,
Choiseul Province Taro Island. The largest reptile is the saltwater crocodile ("Crocodylus porosus") known from Australia. Known birds are the Sanford's fish eagle ("Haliaeetus sanfordi"), the Pacific black duck ("Anas superciliosa"), and the eastern reef egret ("Egretta sacra"). Until the beginning of the 20th century, it was the only habitat of the now extinct Choiseul crested pigeon ("Microgoura meeki"). Choiseul is also an important breeding place for the loggerhead sea turtle ("Caretta caretta"). The flora is represented by mangroves and coconuts. Commercial logging continues to operate in Choiseul throughout the entire province. Nickel Mining is planned to commence in 2016 in Katupika
