This species is one of the most common plants at high elevations within its distribution. Although it is not recorded from any protected areas or cultivated outside of its range, it appears to thrive within its habitat and its population is inferred to be stable. As a result, it is assessed as Least Concern.

This species has been described as being rare in the UAE, but has recently been found to be at least locally common. It had been recorded in the past from an area of metamorphic rocks north of Masafi, and recent investigation of a similar area (Al Khulaybiyah, north of Masafi), recorded c.150 individuals within a single square kilometre (D. Aplin pers. comm. 2019). There is little other information available on the plant's habitat, threats, and conservation. Therefore, it is assessed as Data Deficient at present.

There is little information regarding the distribution of this species within the UAE, in addition to any potential threats it faces or possible uses of the plant. It is generally considered to be rare, although it can only be readily distinguished from the more common C. helenae when it is in fruit. Therefore, it is assessed as Data Deficient.

This species is widespread in the north-east of the UAE. Whilst subpopulations will have undergone a significant decline as a result of coastal development, it is thought that the species still qualifies as Least Concern.

This species has been recorded from inland areas of the UAE in the areas around Shwayb and Al Ain. The distribution does not appear well known, and it may occur more widely in suitable habitat. Grazing by livestock and camels may impact the species, and its habitat is subject to conversion, especially urbanisation. The extent of occurrence (EOO) is restricted, estimated at between 4,500 and 5,500 km², however, the species occurs in many more than ten locations, and it is suspected that any population decline is not approaching that required for a threatened category. As a result, the species is assessed as Least Concern, but the species should be reassessed if further data become available.

This species is generally described as widespread and common. It occurs along coastal areas, in addition to further inland at Al Ain. Therefore, it is assessed as Least Concern.

Although this species appears to be restricted to the Ru'us al-Jibal, it is considered to be locally common within this area. It can also persist at a range of altitudes. It is assessed as Least Concern.

This species is considered to be common along the coasts of the UAE. It is able to persist in disturbed and highly saline environments, where it is referred to as a 'characteristic species'. It is therefore assessed as Least Concern.

The distribution of this species in the UAE requires further study, however, it is likely to be present in all areas of loose sand and sand dune, and it is known to be widespread in the Liwa and Umm az-Zamul areas. The species is considered Least Concern.

This species is distributed in the eastern UAE, with scattered records from the Ru'us al-Jibal at high altitudes, a single locality north of Hatta, and from Wadi Wurayah. The species was found to be locally common in Wadi Wurayah and in the Ru'us al-Jibal. The extent of occurrence (EOO) is estimated to be up to 1,100 km², however, the area of occupancy cannot be estimated as detailed distribution records are not available. Further research is required to confirm the full distribution within the UAE, and the scope of impacts from grazing, however, it is assessed here as Least Concern as it probably occurs in more than ten locations with no evidence of widespread declines in the number of mature individuals or in the quality and extent of habitat.
