Description
Description
Mniarogekko jalu est une espèce de gecko endémique de Nouvelle-Calédonie. Elle se rencontre dans le nord de la Grande Terre et aux îles Bélep.
Mniarogekko jalu is listed as Endangered (criteria B1ab(ii,iii,v)+2ab(ii,iii,v)) because it is restricted to four locations 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
Mniarogekko jalu is endemic to Province Nord in New Caledonia. It is restricted to the far north, from Diahot to Ile Art. The extent of occurrence (EOO) is estimated at 1,341 km2 and the area of occupancy (AOO) at 24 km2.
Population
There is no information on population size or trends.
Habitat
This species appears to be exclusively arboreal, in old-growth, closed-forest habitat with large canopy trees. It has been observed at night, foraging in the twigs and outer foliage of canopy trees or less and trunks in the upper vegetation strata. During the day they shelter in crevices and holes in branches and trunks, often descending close to the forest floor to such sites.
Menaces
Certaines sous-populations peuvent être directement impactées par l'activité minière: Tiebaghi (SLN)
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) and in Province Sud under Code de l'environnement de la Province Sud (Délibération No. 25-2009/APS, 20 March 2009).
