Pancheria robusta is an endemic small tree/shrub of the southern part of Grande-Terre in New Caledonia. It is found in altitudinal shrubland on ultramafic substrate. The main threat impacting this species comes from bushfires which may directly impact two subpopulations. Its area of occupation (AOO) and extent of occurrence (EOO) being respectively estimated to 32 and 222 km², P. robusta is considered Endangered (EN) based on criteria B1ab(iii,v)+2ab(iii,v) with an estimation of five threat-defined locations and a continuing decline in habitat quality and number of individuals.

Habitat and Ecology [top]

Habitat and Ecology:It is found in altitudinal shrubland (550-1,350 m asl) on ultramafic substrates, occasionally in low forest.
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): The main threat impacting this species comes from bushfires which may directly impact two subpopulations (Koghis and Montagne des Sources).

Conservation Actions [top]

Conservation Actions: Unprotected by legislation, this species is found in several protected areas: Massif du Kouakoué, Montagne des Sources, Vallée de la Thy, and Haute Pourina.  As this species is threatened by bushfires, its localities must be included on the maps of Sécurité Civile. The implementation of a "plan de protection de massif" on Montagne des Sources would be very beneficial for this species. Seed banking is also required.

Errata [top]

Errata reason: During the data import process, the order of the names of the Assessors was accidentally changed, the name of one of the Assessors was omitted and an incorrect person was credited as being a Facilitator. This errata version corrects these errors.
