Répartition
Restreint aux îles Bélep
Correlophus belepensis is listed as Critically Endangered (criteria B1ab(ii,iii,v)+2ab(ii,iii,v)) because it is restricted to one location in New Caledonia with a continuing decline in the area of occupancy (AOO), extent and quality of habitat and the number of mature individuals due to a variety of threats.
Aire géographique
Correlophus belepensis is endemic to Province Nord in New Caledonia. It is restricted to the Iles Belep, on the Ile Art, forming one location. It occurs at elevations between 0 and 120 m. The extent of occurrence (EOO) and the area of occupancy (AOO) are estimated at 8 km2.
Population
There is no information on population size or trends.
Habitat
This species is found on hard lateritic soils covered with closed or paraforestier forest.
Menaces
The major threats to Correlophus belepensis are the habitat loss and degradation from wildfires, as well as introduced species (Jourdan 2006) with the invasive ant, Wasmannia auropunctata, which has severe and potentially unsustainable impacts on the geckos (Jourdan et al. 2001). Illegal collection and trafficking at accessible locations are also thought to have significant effects. The introduced bee is a potentially serious issue for this species. In addition, feral cats (Palmas 2017) are expected to exert a predation pressure.
Conservation
This species is protected in Province Nord under Code de l'environnement de la Province Nord (Délibération No. 306-2008/APN, 24 October 2008). This species is not present in any reserve and no species-specific conservation management is currently being undertaken.
