Red List Status -

Near Threatened (NT) , assessed in 10/05/2016

Pycnandra decandra subsp. coriacea is an endemic Shrub or treelet distributed discontinuously on Grande Terre in New Caledonia, from Prony to Plaine des lacs in the South and Kouaoua to Mont Ouazangou in the North. It is found in shrubland on ultramafic substrate at an altitudinal range 100-700 m asl. The main impact identified comes from ongoing mining activities. Therefore, this species does not seem globally threatened. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 112 and 7,958 km², Pycnandra decandra subsp. coriacea is considered Near Threatened (NT) close to VU B1ab(iii,v)+2ab(iii,v) with a decline of habitat quality and number of mature individuals and a number of locations close to 10.
