Pycnandra decandra is an endemic shrub or tree of Grande Terre, from Belep island in the North to Port Boisé in the South. It is found in humid forest or shrubland on ultramafic substrate at an altitudinal range 100-700 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 124 and 12,556 km², Pycnandra decandra 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.
