Scientific Name: Bavayia goroensis
Species Authority: Bauer, Jackman, Sadlier, Shea & Whitaker, 2008

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2011
Date Assessed: 2010-02-09
Assessor/s: Whitaker, A.H. & Sadlier R.A.
Reviewer/s: Cox, N. & Tognelli, M.F.
Justification:
This species is listed as Endangered because it is restricted to two locations in New Caledonia (known from five individual sites), and there are ongoing threats to its habitat. One subpopulation is potentially threatened by expanding mining activities (as well as in habitat between known sites). Decline is probably about 10-15% of overall habitat. At present, none of the sites where the species occurs are protected. Other potential threats that may affect this species are wildfires and invasive species. 

Geographic Range [top]

Range Description: 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. It is known from at least five sites. The species is likely found in appropriate habitat in intervening area. It occurs at elevations between 200 m and 300 m. The extent of occurrence is estimated to be 57 km² (estimated from range map).

Population [top]

Population: 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.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: 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.
Systems: Terrestrial

Threats [top]

Major Threat(s): The most serious threat to Bavayia goroensis is the rapidly expanding nickel industry in the south which will result in the loss of substantial areas of its habitat and isolation of any remaining populations. Wildfires are also a major threat in the maquis habitats. Other issues are habitat degradation by introduced ungulates (deer and pigs) and predation by introduced mammals (rodents and feral cats). It is also expected that the introduced ant, Wasmannia auropunctata, which is now present in most forests in the area, will have detrimental impact as it is known to decimate lizard populations (Jourdan et al. 2000, 2001). A further problem in the south is the conversion of maquis shrublands to exotic forestry plantations.

Conservation Actions [top]

Conservation Actions: 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. 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.
