UICN

Red List Status -

Near Threatened (NT) , assessed in 28/01/2016

Protected species -

in Northern Province

Acropogon merytifolius is an endemic small tree of the central and north-east parts of Grande Terre in New Caledonia. It is found in dense humid forest on a volcano-sedimentary substrate at an altitude of 350-750 m asl. The main impact identified comes from invasive species (seeds predation by rats, bark stripping by rusa rusa deer (Rusa timorensis)) but natural regeneration is observed. Therefore, this species does not seem directly threatened. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 60 and 900 km², A. merytifolius is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations close to 10.
