Assessment rationale/justification
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 km<sup>2</sup>, 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.

Taxon distribution as listed in assessment
This species has been recorded in inland areas of the UAE (Shwayb and Al Ain) (Jongbloed et al. 2003, El-Keblawy 2012). A single specimen is held by RBGE Herbarium, <a href=""http://data.rbge.org.uk/herb/E00357808"">collected from near Shwayb</a>. The EOO is estimated at between 4,500 and 5,500 km<sup>2</sup>, however, the AOO cannot be estimated as detailed locality data are not available. The species is found across North Africa, from the western Sahara to northeast Africa, through the Arabian Peninsula, to southern Iran (Board of Trustees, RBG Kew 2019).

Habitat details as listed in assessment
This is an annual species, recorded from inland sand areas and dunes in the UAE (Brown and Sakkir 2004), that grows up to 0.2-0.35 m (Jongbloed et al. 2003). MEW (2010) also reported the species from cultivated fields. Elsewhere in its range, it is also found in coastal dunes (Quattrocchi 2006).
Threats listed in assessment
Grazing by livestock and camels may impact the species, but there is no information on the impact of this. MEW (2010) considered its habitat to be subject to change (presumably conversion to agriculture) and urbanisation.

This small shrub species typically grows in sand sheets and is able to inhabit saline sand and disturbed areas along the coast (Western 1992, Böer and Saenger 2006, Norton et al. 2009, MEW 2010). As such, it is considered to be a halophyte, or salt-tolerant, species (Sakkir et al. 2017). It is considered to be a characteristic species of its preferred environment (Böer and Saenger 2006). The species can grow up to 0.8 m in height and its leaves vary from linear and hairy to small and round, depending on the season (Jongbloed et al. 2003). It also has winged fruit and produces yellow flowers between September and December (Jongbloed et al. 2003). When crushed, the leaves of this plant produce an unpleasant smell (Jongbloed et al. 2003).

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 km<sup>2</sup>, 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.

Assessment rationale/justification
Bienertia cycloptera occurs from the extreme west of the Arabian Gulf coast, almost to the most northern point of this coastline. Its estimated EOO is 28,675 km<sup>2</sup> and it is considered to be severely fragmented due to the widely scattered localities in which it occurs. Within its range, it is threatened by development of coastal regions which is causing a continuing decline in the extent and quality of available habitat for this species. Therefore, it is currently assessed as Near Threatened.

It is an annual species which can grow up to 1.0 m (Jongbloed et al. 2003, Böer and Saenger 2006). This species has almost cylindrical leaves, a berry like fruit and small yellow flowers which can be seen between October and December (Jongbloed et al. 2003). It grows within saline sand substrate and can found in coastal sabkhas and salt marshes (Jongbloed et al. 2003).
Threats listed in assessment
This species is threatened by the ongoing coastal development occurring the Arabian Gulf coast where it is found.
History
Coastal development within the UAE has been increasing in frequency and intensity since 1996, reducing the extent and quality of available habitat for this species.
