Psychotria pulchrebracteata is an endemic shrub, known in the northeast part of Grande Terre moutain range, from Colnett to Bopope/Inédète in the North of New Caledonia. It occurs in dense humid forest on volcano-sedimentary at an altitudinal range 400-950 m asl. The main impact identified comes from bushfires and invasives species. However, this species does not seem globally threatened. Population is reported sparsely distributed but does not seem to decline. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 32 and 517 km², Psychotria pulchrebracteata is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations equal to five.
