Assessment rationale/justification
Within the United Arab Emirates, this species occurs in the Hajar Mountains (excluding the Musandam Peninsula) from the southern edge of the Musandam in the Hajar Mountains southwards from the Masafi/Dibba depression to Oman. The species is listed as Least Concern, due to its large distribution range with area of occupancy (AOO) 180 km<sup>2</sup> and extent of occurrence (EOO) of 5,463 km<sup>2</sup>, and with no major threats to the presumed large population that may result in it declining fast enough in the near future 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
Habitat details as listed in assessment
Cliffs, cave and boulders on mountains, mountain wadis and rocky outcrops (Gardner 2013). Also found in old building and forts (Gardner 2013). It is a nocturnal species that may be encountered during the cooler months outside its retreats during late afternoons (Gardner 2013). They are excellent climbers typically encountered on vertical or overhanging rock surfaces and also on rocky ground or scree (Gardner 2013). Females lay clutches of two hard-shelled eggs in summer that are glued to vertical rock surfaces within caves or in deep crevices (Gardner 2013). These egg-laying sites are often used communally and the remains of old eggs show they may have been in use over long periods of time (Gardner 2013).
Threats and conservation measures listed
Threats listed in assessment
There are no widespread threats to the species that are known to cause a decline in the population. Quarrying is the only known potential threat to the species within a minority of its wide distribution range.
