Assessment rationale/justification
Within the UAE, this species is restricted to coastal areas of the Arabian Gulf, from Abu Dhabi to Ra's al Khaimah, and recorded from at least one offshore island (Zirku Island). Western (1983a) recorded the species from Saadiyat Island and from Abu Dhabi Island, where it persisted even after levelling and back-filling with material in early 1982. The estimated extent of occurrence (EOO) is 14,328 km<sup>2</sup> and this species is considered to occur at between 5-10 locations, based on the threat of ongoing development. In addition, this development is causing a continuing decline in the extent and quality of the available habitat, especially as a result of it habitat specificity. Therefore, this species is assessed as Vulnerable (B1ab(ii,iii,v)). No regional adjustment is made as the extent of any rescue effect is not known.

Taxon distribution as listed in assessment
Within the UAE, this species is restricted to coastal areas of the Arabian Gulf, from at least Ra's Ghanadha at the northern end of the Al Taweela coastal plains (Brown et al. 2007) to Ra's al Khaimah (Jongbloed et al. 2003) in the north, and recorded from at least one offshore island (Zirku Island, Abu Dhabi Emirate; Brown et al. 2007). In addition, Western (1983a) recorded the species from Abu Dhabi Island and noted that the species formed a dominant broad belt for up to 100 m inland from north of Ra's Ghanadha, behind a clearly-defined barrier beach. Western (1983b) recorded the species from the seaward shore of Abu Dhabi Island, and that it persisted even after levelling and back-filling with material in early 1982. Al Meharibi et al. (2019) show presence to Abu Dhabi Island, hence perhaps the species does indeed persist there. Western also collected the species from Saadiyat Island (date uncertain, but assumed to be the 1980's). The estimated EOO is 14,328 km<sup>2</sup> and it is considered to occur at between 5-10 locations. Globally, its native range spans from Egypt south to Mozambique in Africa, Madagascar, through the Arabian Peninsula to India (Board of Trustees, RBG Kew 2018).

Habitat details as listed in assessment
A tough stoloniferous perennial grass that is usually found in coastal sand, forming mounds just above the highest tide line, with rhizomes spreading to several meters, forming tussocks (Jongbloed et al. 2003). It is a relatively specialised species, being found only within coastal sand dune habitats. Flowers from September until November (Jongbloed et al. 2003). It is dormant during the summer (Brown et al. 2007).
Threats listed in assessment
Grazing by livestock may impact the species in parts of its range, however the impacts from coastal development have been significant in terms of declines in this species. Known localities, such as Saadiyat Island, are now very developed which reduces the likelihood of this species persisting there.
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.

Assessment rationale/justification
This species has a very restricted distribution within the UAE, having only been recorded from Jebel Qitab and Wadi Hayl. Its estimated extent of occurrence (EOO) is 24 km<sup>2</sup> and area of occupancy (AOO) is 8 km<sup>2</sup>. According to the most important threat to this species (drought and extreme weather), it is considered to occur at one threat-based location. In addition, this species is experiencing an ongoing decline in the extent and quality of available habitat due to ongoing droughts and grazing by animals. Therefore, this species is assessed as Critically Endangered (CR B1ab(iii)+2ab(iii)).

Habitat details as listed in assessment
Grewia erythraea generally inhabits hillsides (Jongbloed et al. 2003). This perennial shrub species has woody stems and can grow up to 150 cm in height (Jongbloed et al. 2003, Fawzi and Ksiksi 2012). It produces small white flowers between October and February in addition to producing a red berry fruit in 3-4 parts (Jongbloed et al. 2003). It is a characteristic species of the submontane zone which is dominated by grasses, herbs and subshrubs (Patzelt 2015).
Threats listed in assessment
This species is browsed by native grazers including gazelle and ibex, although they don't appear to be a threat to the vegetation (Ghazanfar and Fisher 1998). It is, however, also thought to be browsed by feral goats (Feulner 2011) which may pose a threat, as it is often seen to be heavily grazed (Feulner 2011). This species can grow to the size of a small tree, however, it is typically reduced to a cushion by browsers (Feulner 2016).

Assessment rationale/justification
Despite being restricted to the Hajar Mountains and Ru'us al-Jibal in the UAE, this species is known to occur within at least one protected area in its range. In addition, it has been suggested that its supposed rarity may instead be due to being overlooked rather than actually being scarce. It is therefore assessed as Least Concern.

Habitat details as listed in assessment
This annual species has similar ecology to Geranium mascatense: it has round, lobed leaves and dark pink flowers with a black centre, which can be seen between February and May (Jongbloed et al. 2003). However, Geranium trilophum is thought to have larger flowers (Jongbloed et al. 2003). Similarly to G. mascatense, it may well inhabit gravel substrate, in addition to shady places within both wadis and plantations (Jongbloed et al. 2003). Within the Wadi Wurayah National Park, this species is known to grow on north-facing rubble slopes which are shaded by a cliff (Feulner 2016).
