Pycnandra heteromera is an endemic shrub or tree of Grande-Terre in New Caledonia, from Ouenghi in the North to Fausse Yaté in the South. It is found in shrubland on ultramafic substrate at an altitudinal range 300-1,000 m asl. The main impact identified comes from bushfires. The subpopulation in Mount Dore is suspected of having been destroyed by fire. Therefore, this species does not seem globally threatened. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 36 and 1,076 km², Pycnandra heteromera is therefore considered Vulnerable (VU) according to criteria B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations equal to 9.
