Cupaniopsis tontoutensis is an endemic scrambling shrub of Grande Terre in New-Caledonia, restricted to the Tontouta valley. It is found in shrubland and dense formation of gymnostoma chamacyparis on an ultramafic substrate at an altitudinal range 20-400 m asl. Recurrent bushfires and on-going mining activities in the Tontouta valley may contribute to the degradation of its habitat. This taxon is not well circumscribed according to taxonomist Jérôme Munzinger. Cupaniopsis tontoutensis is therefore assessed as Data Deficient (DD) for taxonomic reason.

Geographical area


Cupaniopsis tontoutensis is an endemic scrambling shrub of Grande Terre in New-Caledonia, restricted to the Tontouta valley.

Population


Population size is unknown.

Habitat


It is found in shrubland and dense formation of gymnostoma chamacyparis on an ultramafic substrate at an altitudinal range 20-400 m asl.

Threats


Recurrent bushfires and on-going mining activities in the Tontouta valley may contribute to the degradation of its habitat. Some individuals are directly impacted by on-going mining activities (Gallieni/Vulcain and Opoué mines).

Conservation


Cupaniopsis tontoutensis is protected by the code de l'environnement of province Nord and province Sud. It does not occur in any protected area. This species would benefit from emergency in-situ and ex-situ conservation measures. Taxonomic clarification is urgently needed on this probable complex of species.
