Although common at the only site from where it was most recently recorded, C. euryotis has been assessed as Endangered because it is endemic to one small island off New Caledonia, its estimated extent of occurrence is approximately 150 km², and it is known only from two locations. This species has only been recorded from forest habitat which is being degraded and lost on Ile des Pins. The number of individuals is also declining as a result of habitat loss and also because of invasive species. Conservation measures are needed to ensure the survival of this species, such as the establishment of protected areas.
|Range Description:||C. euryotis is endemic to New Caledonia. It is known only from two sites on Ile des Pins (Isle of Pines); at the town of Vao and at a remnant of a closed forest near Waa Mé Bay (Bauer and Sadlier 1994, Sadlier et al. 2006). The Isle of Pines has an area of 152 km², however, the area of suitable habitat is considerably less (Sadlier et al. 2006). A survey of the islets surrounding the Isle of Pines did not find any individuals (Sadlier et al. 2006). Recorded at elevations up to 200 m asl.|
The extent of occurrence is estimated at approximately 150 km² and the area of occupancy at <10 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.]

There are no data on population size and trends for C. euryotis. It is assumed that there has been a reduction in the area of occupation resulting from loss and fragmentation of forest habitats through clearance for occupation, agriculture and afforestation, and by infestation of areas by invasive species. At the single site from which it has been recorded in recent times, C. euryotis was considered to be locally common in good habitat (Bauer and Sadlier 1993).
|Current Population Trend:||Unknown|
|Habitat and Ecology:||C. euryotis inhabits coastal closed forest habitat. It is diurnal, terrestrial, and is attracted to sunlight. It shelters beneath litter and stones, and basks and forages in light-gaps.|
C. euryotis is oviparous, with a clutch size of two to three eggs (Sadlier et al. 2006).
|Major Threat(s):||Celatiscincus euryotis is most at risk to further loss and fragmentation of coastal forest habitats through clearance for agriculture and occupation, and from wildfires. In forested habitats there is also a significant threat from the introduced ant, Wasmannia auropunctatus, which is known to decimate lizard populations (Jourdan et al. 2001). Predation by introduced mammals (rodents and cats) is also likely to be a constant threat.|
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 found in a protected area and does not have any other conservation measures in place for it. Actions are required to ensure the survival of this species, such as founding protected and managed areas on the Ile de Pins, and species-based research and monitoring.
