Pancheria humboldtiana is an endemic shrub of the southern part of Grande Terre (restricted to Monts Humboldt and Kouakoué) in New Caledonia. It is found in altitudinal shrubland on ultramafic substrate. This species does not seem directly threatened because of its altitudinal habitat. Pancheria humboldtiana is considered Near-Theatened close to Vulnerable (VU) using criteria D2 because of its small area of occupancy (AOO) being estimated to 16 km² and the potential impact of climate change.
Geographical area
Pancheria humboldtiana is restricted to the southern part of Grande Terre in New Caledonia : Monts Humboldt and Kouakoué
Population
This species is rather common. It is knwon of two subpopluations.
Habitat
It is found in altitudinal shrubland (1,300-1,640 m asl) on ultramafic substrate.
Threats
This species does not seem directly threatened because of its altitudinal habitat. Climate change could be a potential threat for altitudinal species.
Conservation
Unprotected by legislation, this species is found in two protected areas : Massif du Kouakoué, Mont Humboldt. It is recommended to monitor the populations and to investigate the potential impact of climate change on this type of altitudinal species, especially by following the evolution of the altitudinal limit between forest and shrubland.
