Alyxia mucronata is an endemic shrub from New Caledonia restricted to the north west of Grande Terre, from Paéoua to Tiébaghi. It is found in shrubland on ultramafic soil between 98 and 1,071 m asl. The population size of Alyxia mucronata is unknown. The main threats are bushfires and mining activities at Tiébaghi and Kopéto, that cause habitat degradation. Its extent of occurrence (EOO) and area of occupancy (AOO) are 910 and 72 km², respectively, while the number of locations is estimated to be 9. Therefore, Alyxia mucronata is listed as Vulnerable (VU) under criteria B1ab (i,ii,iii,v)+B2ab(i,ii,iii,v) with a decline of all the concerned subcriteria.
