Epibator greeri is listed as Endangered because it has a restricted distribution and it is known from only three localities (making three locations) and there is continuing decline in its extent and quality of its habitat and number of mature individuals due to a variety of threats.
Aire géographique
Epibator greeri is endemic to New Caledonia. The species is known from two distant areas (Koumac and Koghis-Rivière Bleue). The extent of occurrence is estimated at 3,760 km2 and the area of occupancy at 16 km2.
Population
There is no information on population size and trends for Epibator greeri. The population in the north is expected to have suffered a substantial reduction in population size and extent in the past from the loss of forest habitat from clearance for agriculture, and logging, and from the effects of wildfires.
Habitat
There is no information on ecology or behaviour for this species. It is assumed to be diurnal and attracted to sunlight from comparison to the sister taxon Epibator nigrofasciolatum. As the gravid holotype was taken into captivity, the species is known to be oviparous with two eggs per clutch, and requiring 44 days of incubation for the eggs to hatch (Bauer and Sadlier 2000).
Menaces
The main identified threats on Epibator greeri are the habitat loss and degradation from wildfires and predation pressure from introduced mammals such as rodents (Thibault 2017) and cats (Palmas 2017). The Koghi subpopulation may face disturbance from Noumea vicinity.
