Beilschmiedia neocaledonica is an endemic tree restricted to the east coast of Grande Terre in New Caledonia. This species is known of three subpopulations (Kouaoua, Thio, Yaté). It is found in altimontane shrubland and dense humid forest on ultramafic substrate at an altitudinal range 500-1,200 m asl. On-going mining activities impact several subpopulations. Indeed, extraction projections on the coming 25 years will lead to the decline of populations, especially in Camp des Sapins and Kouaoua (SLN). Its extent of occurrence (EOO) and area of occupancy (AOO) are respectively estimated to be of 1215 and 44 km² while the number of locations is estimated to be 5. Beilschmiedia neocaledonica is therefore assessed as Endangered (EN) with criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) with a continuing decline of all concerned sub-criteria.

Geographical area


Beilschmiedia neocaledonica is an endemic shrub restricted to the east coast of Grande Terre in New Caledonia. This species is known of three subpopulations (Kouaoua, Thio, Yaté).

Population


Population size is unknown.

Habitat


It is found in altimontane shrubland and dense humid forest on ultramafic substrate at an altitudinal range 500-1,300 m asl.

Threats


On-going mining activities impact several subpopulations. Indeed, extraction projections on the coming 25 years will lead to the decline of populations, especially in Camp des Sapins and Kouaoua (SLN).

Conservation


Beilschmiedia neocaledonica is not protected by legislation but it occurs in one protected area (réserve naturelle de la Fausse-Yaté). It is noted that this species is part of a collaboration for ex-situ conservation between SLN (Société le Nickel) and IAC (Institut Agronomique néo-Calédonien). It is recommended to continue efforts for ex-situ conservation and to follow-up existing populations. It is moreover recommended to protect it legally.
