Scientific Name: Marmorosphax boulinda
Species Authority: Sadlier, Smith, Bauer & Whitaker, 2009

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2011
Date Assessed: 2010-09-09
Assessor(s): Whitaker, A.H. & Sadlier, R.A.
Reviewer(s): Tognelli, M. & Cox, N.A.
Justification:
Marmorosphax boulinda is listed as Vulnerable because it is known from only a single location with a very small area of occupancy. If mining was to commence on massif Boulinda, or if a wildfire damaged a substantial area of the habitat for this species, it could trigger a status of Critically Endangered in a very short period of time.

Geographic Range [top]

Range Description:This species is endemic to Province Nord, New Caledonia. It is known only from a single location near the summit of the ultramafic massif Boulinda, on the central west coast of Grande Terre. It occurs at elevations from 900 to 1,000 m. The extent of occurrence is approximately 67 km² (calculated from polygon map), but it is expected to occur more widely in the Boulinda massif. The area of occupancy is estimated to be 1 km².

Population [top]

Population:There is no information on population size and trends for Marmorosphax boulinda, but destruction of its montane forest habitat by past mining activates and from recurrent wildfires in the adjacent maquis shrublands is assumed to have reduced the population size and extent.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits closed montane forests. It is diurno-nocturnal, cryptozoic and terrestrial. It shelters beneath logs, rocks and deep leaf litter, and forages in cover.
Systems:Terrestrial

Threats [top]

Major Threat(s): The greatest threat to this species is from further habitat destruction and fragmentation. Mineral exploration and mining has occurred on the Boulinda massif in the past and with the rapidly expanding mining industry it is expected this will recommence. Montane forest remnants and forest margins are also vulnerable to the recurrent wildfires in the adjacent maquis shrubland. Introduced mammals (rodents, cats and pigs) are a potential predation risk and introduced ungulates (deer and pigs) threaten habitat quality, particularly through damaging the litter layer.

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). It is not present in any reserves and no conservation management is currently being undertaken. Given its highly limited area of occupancy, formal protection of existing habitat for this species is a high priority.
