Pancheria robusta is an endemic 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 occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 32 and 222 km², Pancheria robusta is considered Endangered (EN) using criteria B1ab(iii,v)+2ab(iii,v) with an estimation of 5 locations and a decline of habitat quality and number of individuals.
Geographical area
Pancheria robusta is restricted to the southern part of Grande Terre where it occurs in 4-5 massifs : mont Kouakoué, montagne des Sources, Koghis/Thy, haute Pourina with an old observation on mont Pénari.
Population
This species is not very common. It is known from 4-5 subpopulations.
Habitat
It is found in altitudinal shrubland (550-1,350 m asl) on ultramafic substrate, occasionnaly in low forest.
Threats
The main threat impacting this species comes from bushfires which may directly impact two subpopulations (Koghis, Montagne des Sources).
Conservation
Unprotected by legislation, this species is found in several protected areas : Massif du Kouakoué, Montagne des sources, Vallée de la Thy, Haute Pourina As this species is threatened by bushfires, its stations must be included in the maps of Sécurité Civile. The implementation of a "plan de protection de massif" on Montagne des Sources would be very benefic. Moreover, seeds banking seems pertinent.
