Psychotria oubatchensis is an endemic shrub, known in Grande Terre from col d'Amoss in the north to Mont Panié in the South of New Caledonia. It occurs in dense humid forest on volcano-sedimentary substrate at an altitudinal range 400-1,250 m asl. The main impact identified may come from bushfires on one sub-population (col d'Amos), however it is a forest species that occurs mostly in high altitude and population does not seem to decline. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 40 and 275 km², Psychotria oubatchensis is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality.
