araucaria rulei

Araucaria rulei (Rule araucaria, graceful pine) is a species of conifer in the family Araucariaceae. It is endemic to New Caledonia, where it is an endangered species. Its populations are fragmented and are generally made up of scattered individuals. It is restricted to serpentine soils, often with high nickel levels, and its natural range is almost completely restricted to areas rich in nickel. Nickel mining in New Caledonia has consequently been a major cause of its decline.
