Cattle farms use about 57% of the total area, mostly in central and eastern Cape York Peninsula. About 20% is indigenous land, with the entire West coast being held under Native title. The remainder is mostly National Park and managed by the Queensland Parks and Wildlife Service. Land uses include broad acre pastoralism, bauxite and silica sand mining, nature reserves, tourism and fishing. There are big deposits of bauxite along the west or Gulf of Carpentaria coast. Weipa is the centre for mining. Much has been damaged by overgrazing, mining, fires, wild pigs, cane toads, weeds, and other introduced species. But Cape York Peninsula remains fairly unspoilt with intact and healthy river systems and no recorded plant or animal extinction since European settlement.
