Canacomyrica monticola is an endemic shrub of New Caledonia, widespread in southern Grande Terre from Thio in the north to Goro in the south. It occurs in forest or shrubland on ultramafic substrate at an altitudinal range 160-1,300 m asl. The main impact identified comes from mining activites around Goro and bushfires. Its area of occupation (AOO) and extent of occurrence (EOO) being respectively estimated to 116 and 2,221 km², Canacomyrica monticola is considered Near Threatened (NT) close to VU B1ab(iii,v)+2ab(iii,v) with a decline of habitat quality and a number of locations above 10.
