Nannoscincus koniambo is listed as Critically Endangered (criteria B1ab(ii,iii,v)+2ab(ii,iii,v)) because it is restricted to only one locality on the Koniambo massif, with the extent of occurrence (EOO) and the area of occupancy (AOO) estimated at 8 km2. There is a continuing decline in the area of occupancy and extent and quality of habitat due to a variety of threats.
Aire géographique
Nannoscincus koniambo is endemic to Province Nord in New Caledonia. It occurs in only one locality on Koniambo massif, at elevations between 800 and 1,000 m. The extent of occurrence and the area of occupancy are estimated at 8 km2.
Population
There is no information on population size or trends. It is presumed that development of a large nickel mine on the Koniambo massif has caused further habitat loss and led to a population decline.
Habitat
The holotype was collected inside a rotting log and the paratype in shallow leaf litter.
Menaces
Certaines sous-populations peuvent être directement impactées par l'activité minière: Koniambo (KNS)
