Cunonia rupicola is an endemic shrub of north-east Grande Terre in New Caledonia. It is found in dense humid forest at mid altitude on volcano-sedimentary substrate. The main threats impacting this species come from habitat degradation caused by bushfires and invasive species (Rusa rusa deer (Rusa timorensis) and feral pigs). Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 16 and 9 km², Cunonia rupicola is considered Endangered (EN) using criteria B1ab(iii,v)+2ab(iii,v) with an estimation of 3 locations and a decline of habitat quality and number of individuals.

Geographical area


This species is restricted to north-east Grande Terre in New Caledonia where it is known on 2 massifs (Ouaïème and Panié) and suspected on a third one (Colnett).

Population


Population size is unknown.

Habitat


It is found in dense humid forest at mid altitude (550-900 m asl) on volcano-sedimentary substrate.

Threats


The main threats impacting this species come from habitat degradation caused by bushfires and invasive species (Rusa rusa deer (Rusa timorensis) and feral pigs).

Conservation


Unprotected by legislation, this species is found in one protected area : Mont Panié As this species is threatened by bushfires, its stations must be included in the maps of Sécurité Civile. Generally, it is suggested to study the protection of the Roches de la Ouaïème. This species would benefit from ex-situ conservation (seeds banking).
