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
