Although Bavayia madjo is known from only two localities, it is listed as Near Threatened because it occurs in a protected area and the potential suitable habitat is very large and the risk of habitat loss or degradation is very low (almost qualifies for listing under criterion B1ab(iii)+2ab(iii)). There are established populations of naturalized predators (e.g. rodents and cats) within the range of this gecko, but it is not known if they have an impact on its population. Further information on population size and  trends is needed, as well as on the threats to this species to determine whether it should be listed in a higher threatened category.

Geographic Range [top]

Range Description:Bavayia madjo is endemic to Province Nord, New Caledonia. It is known only from the Panié massif in north-eastern Grande Terre. This species has been recorded at just two localities, Mt Ignambi and Mt Panié, but it is expected to be widely distributed along the massif between these two sites as the habitat is continuous and relatively undisturbed. It occurs at elevations above 850 m. The extent of occurrence is approximately 225 km², and the area of occupancy is estimated at 2 km².

[Extent of occurrence was based on a crude measure of overall length times width of the most distant known locations (a rough measure of the line around the points), except for very widespread species where the published areas of the islands were taken.  Area of occupancy is a contraction of that rough estimate for extent of occurrence based on where habitat remains.]

Population [top]

Population:There is no information on present population density or trends for this species.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits closed montane forest. It is nocturnal and presumed to be arboreal, sheltering by day beneath loose bark and in tree or rock crevices.
Continuing decline in area, extent and/or quality of habitat:No

Threats [top]

Major Threat(s): Rodents and feral cats are common throughout the Panié massif and are expected to exert a predation pressure on Bavayia madjo. Habitat degradation is also occurring from introduced ungulates (deer and pigs), but otherwise the high elevation forests of the Panié massif are amongst the least modified and most secure in New Caledonia.

Conservation Actions [top]

Conservation Actions: 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).  This species is present in the Réserve de Nature Sauvage du Mt Panié. No conservation management is currently being undertaken, but this species may potentially benefit from proposed predator control in the La Guen catchment on Mt Panié.
