Stigmaphyllon taomense is an endemic species from New Caledonia. It is restricted to the north east of Grande Terre, from Népou at the southern limit to Koumac at the northern limit was well as in Art island (Belep islands). This species occurs in scrubland on ultramafic substrate between 5 to 250 m asl. The main identified threats are linked to habitat damage by invasive species such as Rusa Deer (Rusa timorensis)) and uncontrolled bushfires. It can also be impacted indirectly by mining activities (road constructions, mining infrastructures, soil erosions). Its extent of occurrence (EOO) and area of occupancy (AOO) are respectively estimated to be of 3,118 km² and 60 km² while the number of locations is estimated to be nine. S. taomense is therefore assessed as Vulnerable (VU) with criteria B1ab(iii,v)+2ab(iii,v) with a continuing decline of of its habitat quality and number of mature individuals.
