Alstonia odontophora is a tree growing up to 6-10 m high endemic from New Caledonia. It is restricted to the Grand Sud massif in the south the Grande Terre, from the far south of the Grande Terre to the upper limit at Dumbea area with a discattered observations at Thio. It grows in forets on ultramafic substrate at an altitude range of 150-1,100 m asl. This species does not seem threatened although some subpopulations may be impacted by bushfires and a mining activities at Goro. This species is common and it occurs in several protected areas. With an Extent of Occurrence (EOO) and Area of Occupancy (AOO) respectively equal to 1,955 and 240 km², Alstonia odontophora is considered as Least Concern (LC).
