Red List Status -Near Threatened (NT) , assessed in 15/09/2016
Psychotria schumanniana is an endemic shrub, known in Grande Terre from Mandjélia to Ouaïème in the North 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, however it is a forest species and population does not seem to decline. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 52 and 181 km², Psychotria schumanniana is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality.
