Assessment rationale/justification
In the UAE, this species is restricted to the southern Hajar Mountains and to Jebel Hafeet. The extent of occurrence (EOO) is restricted, and the area of occupancy (AOO) is also likely to be highly restricted given the scattered distribution. The species occurs in more than ten locations, including protected areas, however the population size is inferred to be low, likely to be less than 1,000 mature individuals. As a result, the species qualifies as Vulnerable (D1). Whilst the species occurs in Oman, the potential for any rescue effect is not known, and no regional adjustment is applied.
