Phyllanthus favieri var. kaalaensis is endemic to New Caledonia, only known from Mont Kaala, in north west of Grande Terre. It occurs in shrubland on ultramafic substrate between 600 and 1,050 m asl. Its area of occupancy (AOO) and extent of occurrence (EOO) are both estimated to be 8 km², and it is known from a single location. Main threats include ongoing mining activites and bushfires. Therefore P. favieri var. kaalaensis is listed as Critically Endangered (CR) with criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v).

Geographical area


P. favieri var. kaalaensis is endemic to New Caledonia, where it is only known from Mont Kaala, in the north west of Grande Terre.

Population


Population size is unknown.

Habitat


P. favieri var. kaalaensis occurs in shrubland on ultramafic substrate between 600 and 1,050 m asl.

Threats


The main threats are ongoing mining activites on Mont Kaala (SMPT (Michel37)), as well as bushfires.

Conservation


P. favieri var. kaalaensis is protected by legislation in Province Nord, but does not occur in any protected areas. This species is cultivated at the IAC (Institut Agronomique de Nouvelle-Calédonie) nursery of Saint-Louis. This taxon would benefit from ex situ and in situ emergency conservation actions. It is recommended to monitor and preserve known populations in delimited areas, and to inform the local authority responsible for the coordination of the firefighting effort about the presence of the taxon in the concerned areas. It would also be advised to run multiplication tests in order to assist future planting operations. Finally, prospection in the valleys of Mont Kaala is needed to better estimate the size of the population and understand potential threats.
