Pycnandra carinocostata is endemic shrub or small tree of Grande-Terre in New Caledonia, confined to areas with ultramafic soil from Yaté in the south to the Tchingou massif in the north. It occurs primarily in humid forest on ultramafic substrate at high altitudes, from 900m and upwards, and it has occasionally been collected on lower mountains. 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 52 and 6853 km², Pycnandra carinocostata is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations equal to 10.
