Taxonomy
Planchonella roseoloba
Red List Status -
Near Threatened (NT) , assessed in 29/11/2019Protected species -
in Northern Province
Planchonella roseoloba is an endemic tree of New Caledonia, where it is restricted to the center and northeast of Grande Terre. It grows in dense humid forest on volcano-sedimentary substrate from 300 to 700 m asl. The main threats to this species are bushfires and possibly also invasive species. Its extent of occurrence (EOO) and area of occupancy (AOO) are 641 and 48 km², respectively, and the number of locations is estimated to be six. Therefore, P. roseoloba is listed as Near Threatened (NT), close to Vulnerable under criteria B1ab(iii,v)+B2ab(iii,v).
