Red List Category & Criteria:	Endangered B1ab(i,iii) ver 3.1
Year Published:	2010
Assessor/s:	Raxworthy, C.J. & Vences, M.

Justification: Lycodryas inopinae has been assessed as Endangered under criterion B1. This species has an extent of occurrence of less than 5,000 km² and is found in fewer than five locations. Ongoing clearing activity in the region, including illegal clearing in Anakarana Reserve, threatens this species. This species is likely to be downlisted to a lower threat category in future assessments once the Montagne des Francais massifs, which overlaps with this species distribution, have been designated as a protected area and afforded legal protection. Further research and monitoring of the population of L. inopinae should be undertaken.

Geographic Range [top]

Range Description:	This species is known only from a few specimens collected in northern Madagascar, including the holotype found in Antsiranana province, specimens collected at the Montagne des Francais massifs (D'Cruze et al. 2007) and a specimen collected at Ankarana Reserve (M. Vences pers. comm.). This species occurs between 120 and 330 m above sea level. The area in which this species is known to be distributed is approximately 345 km².

Population [top]

Population:	Surveys of the massif Montagne des Francais found that this species was rare at that location (D'Cruze et al. 2007).
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This species is arboreal, nocturnal and is found in karstic dry forest (Glaw and Vences 2007).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	This species is found within a habitat that has been cleared or degraded by human activities such as the expansion of agriculture, including rice and maze production, and the clearing of land for grazing and logging (D'Cruze et al. 2007). However, all specimens were found in areas which are already protected or scheduled to become protected, so that the threats are unlikely to affect the species in these areas in the future.

Conservation Actions [top]

Conservation Actions:	There are no known species-specific conservation measures in place for this species. However, one specimen was found within Ankarana Reserve and the specimens found in Montagne des Francais are within a region that is scheduled to become a protected zone soon (M. Vences pers. comm.). Further research into the population, habitat status, and threats to this species should be carried out, and population monitoring is recommended.
