Assessment rationale/justification
Within the United Arab Emirates, this species is widespread throughout the Hajar Mountain range. The species is listed as Least Concern in view of its wide distribution range, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a threatened category. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).

Habitat details as listed in assessment
The species is found in mountainous and rocky areas, where it lives on stony plains, in wadi beds, and on scree slopes, from sea level to 1,000 m asl. The species is often encountered in and around cultivated land within its range and under construction debris. It is a nocturnal species that is mostly encountered on the ground, although they are excellent climbers and can be encountered climbing on trees. By day, they are most often encountered sheltering under stones. Breeding occurs throughout the warm season with females laying one or two, thin-shelled and slightly oval eggs at four-week intervals (Gardner 2013).
