Listed as Vulnerable under Criterion D2, as the species is confined to a single site, Montagne d'Ambre, with a plausible future threat from human encroachment that could impact the species. If the threat became active, the species would likely immediately qualify for listing as Critically Endangered as its extent of occurrence may be below 100 km²; alternatively its extent of occurrence is not much greater than 100 km² and it is therefore plausible that it could be driven to Critically Endangered within a short time after the threat became operational, since it would occur at a single location (where the threat is agricultural expansion and logging) and there would be a continuing decline in the quality and area of habitat (qualifying the species for listing under criterion B1ab(iii)).
|Range Description:||This species is thought to occur only in Montagne d'Ambre in northern Madagascar, at about 1,000 m elevation (Glaw et al 1999, Raxworthy and Nussbaum 1995). The park has an area of 385 km², although due to its apparently very narrow elevational range the lizard's true distributional extent is likely to be considerably smaller, and may be below 100 km² (C. Raxworthy pers. comm. June 2011).|

|Population:||During the rainy season this species is reported to be locally very common (Glaw and Vences 2007).|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species inhabits rainforest and during the day it is active in the leaf litter or on small branches a few centimetres above the ground. At night it can be found roosting on branches approximately 5 - 15 cm above the ground (Glaw and Vences 2007).|
|Use and Trade:||There is no use or trade in this species.|
|Major Threat(s):||There are no major threats to this species, but Montagne d'Ambre is under immediate future threat of several activities expanding into the park, including logging (charcoal), cattle grazing, agricultural clearance for rice production, and rosewood collection (N. D'Cruze and L. Durkin pers. comms. 2011).|
|Conservation Actions:||This species occurs in Parc National Montagne d'Ambre, and is included on CITES Appendix II. The reserve should be managed to limit the risks to this species of potential threats from human activities, and population trends should be monitored to ensure that these measures are effective.|
