Capparis parvifolia is a newly described species. It is endemic to New Caledonia, where it is only known from Mont Kaala, in the north west of Grande Terre. It is found in shrubland on ultramafic substrate between 100 and 800 m asl. Its extent of occurrence (EOO) and area of occupancy (AOO) are both estimated at 8 km², and the species exists in a single location. Its main threats are mining activities and uncontrolled bushfires. Therefore, C. parvifolia is listed as Critically Endangered (CR) under criteria B1ab(i,ii,iii,v)+2ab(i,ii,iii,v).

Geographical area


C. parvifolia 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


C. parvifolia occurs in shrubland on ultramafic substrate between 100 and 800 m asl.

Threats


The main threats are mining activities (Michel 37 (SMT) and Etoile du Nord (SLN)) and uncontrolled bushfires.

Conservation


C. parvifolia is not protected by any legislation in New Caledonia and does not occur in any protected areas. This species would benefit from ex situ and in situ emergency conservation actions. It is recommended to monitor and preserve known populations on part of the mining site, and to inform the local authority responsible for the coordination of the firefighting effort about the presence of the species in the concerned areas. It would also be advised to run multiplication tests in order to assist future planting operations. Finally, prospection in the lower valleys of Mont Kaala is needed to better estimate the size of the population and understand potential threats.
