Red List Status -

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

Pycnandra deplanchei subsp. deplanchei is an endemic shrub of Grande Terre in New Caledonia, from Bogota in the North to Tamoa in the South. It is found in shrubland on ultramafic substrate at an altitudinal range 10-500 m asl. The main impact identified comes from ongoing mining activites and bushfires. Therefore, this species does not seem globally threatened. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 64 and 1,169 km², Pycnandra deplanchei subsp. deplanchei is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations close to 10.
