Acropogon jaffrei is an endemic small tree of the west coast of Grande Terre in New Caledonia. This species is known from only two populations (Koniambo, Boulinda). It is found in sclerophyl and humid forest on ultramafic substrate at an altitude of 30-300 m asl. Its area of occupancy (AOO) and its extent of occurrence (EOO) are estimated respectively to be 60 and 561 km² while the number of locations is 3. The threats to A. jaffrei are linked to habitat degradation due to bushfires and mining activities related to Koniambo and Boulinda mining projects. Using criteria B, A. jaffrei does qualify for Endangered (EN) B1ab(iii)+2ab(iii).
