Statut liste rouge -En danger (EN) , évaluée le 11/12/2017
Espèce protégée -en Province Sud , en Province Nord
Espèce connue du plateau de Goro et de la plaine des Lacs
Forêt humide et maquis
This species is listed as Endangered because it is restricted to two locations in New Caledonia, and there are on-going threats to its habitat. One subpopulation is potentially threatened by expanding mining activities. At present, even though the Plaine de Lacs region is classified as a Ramsar area, none of the sites where the species occurs are protected. Other potential threats that may affect this species are wildfires and invasive species.
Bavayia goroensis is endemic to Province Sud in New Caledonia. It is known only from the Goro Plateau - Plaine des Lacs region in the extreme southeast of Grande Terre. The species is likely found in appropriate habitat in intervening area. It occurs at elevations between 200 and 300 m. The extent of occurrence and the area of occupancy are estimated to be 28 km².
There is no information on population size or trends. It is presumed that the past wildfires and logging that have affected large parts of the Plaine des Lacs region have reduced the extent of habitat for Bavayia goroensis and led to a reduction in and fragmentation of the population. Afforestation projects may also have removed habitat. The development of a large new nickel mine in the area is causing further habitat loss.
This species occurs in maquis shrubland (including maquis arbustif and maquis paraforestier) and humid forest. It is nocturnal and arboreal. It shelters by day in tree holes and beneath loose bark and forages at night in the canopy.
Certaines sous-populations peuvent être directement impactées par l'activité minière: Goro (VALE)
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). Not listed on CITES. This species is not present in any reserves and no species-specific conservation management is currently being undertaken. Protecting the wetlands of Plaine des Lacs recently recognized by RAMSAR through a management plan and the declaration of protected areas would be benefit to this species. Further research is needed into the distribution, habitat status, and threats to this species. As habitat degradation is impacting this restricted species, protected areas should be considered to help reduce the degree of threat. Monitoring is also necessary as if threats continue, significant declines may occur increasing the extinction risk of this species.
