Emmenosperma pancherianum was first considered endemic to New Caledonia until its recent discovery in Queesland. It is now an autochtonous shrub from New Caledonia, mostly distributed in the west coast of Grande Terre as well as at Ile des Pins. It occurs in low dry forests (including coastal forests) on volcano-sedimentary and calcareous substrates up to 150 m asl. Its habitat is among the most threatened in the country. Dry forests have been reduced dramatically, both in size and quality. They have been severely cleared for agricultural purposes over the last century and what remains today are highly fragmented patches that suffer intense predation by the introduced Rusa Deer (Rusa timorensis). These low habitats are also impacted by reccurent bushfires. Its Area of Occupancy (AOO) and Extent of Occurrence (EOO) being respectively estimated to be 148 and 8,474 km², Emmenosperma pancherianum is considered Near Threatened (NT) close to VU B1ab(iii,v)+2ab(iii,v) with an estimated decline of all the concerned subcriteria and a number of locations above 10.

Habitat


Emmenosperma pancherianum occurs in low dry forests (including coastal forests) on volcano-sedimentary and calcareous substrates up to 150 m asl.

Threats


The main impact identified areas are the decline of dry forests both in size and quality due to land clearing for agricultural purposes over the last century and what remains today are highly fragmented patches that suffer intense predation by the introduced Rusa Deer (Rusa timorensis).

Conservation


This autochtonous species is protected by legislation in New Caledonia and it does occur in only 1 protected area: Ouen Toro.
