Assessment rationale/justification
This species has a restricted distribution within the UAE, consisting of two major subpopulations. These populations are considered to be severely fragmented. At least one of its known localities, Khor Zawra, has been lost due to land being converted into a golf course. Ongoing development is occurring at other sites, such as Jebel Hafeet, and this suggests that the overall population is declining. The estimated EOO for this species is 1,432 km<sup>2</sup> which falls within the threshold for threatened categories. Therefore, this species is assessed as Endangered (EN B1ab(iii,iv,v)).

Habitat details as listed in assessment
This is a perennial bulb species. It has two or three narrow, curled leaves and is found in gravel in low, limestone hills (Jongbloed et al. 2003). Flowering takes place from February to March, producing two brown flowers per plant, but only after rains (Jongbloed et al. 2003).
Threats listed in assessment
This species may be at risk from development at Jebel Hafeet. One of its previous localities, Khor Zawra, has been lost due to land conversion for use as a golf course.
History
This species has been fragmented with a small distribution in the past, with a backcast listing of EN B1ab(iii). Threats due to ongoing development and land conversion are still having a negative impact on this species.

Feulner (2011) reports occurrence in the Hajar Mountains (wadis, lower slopes, foothills and alluvial plains) without details. Mahmoud et al. (2018) reported the species from plantations along the western slopes of the Hajar Mountains. <a href=""http://data.rbge.org.uk/herb/E00003768"">RBGE Herbarium </a>holds a specimen from the east coast from the 'Kalba date gardens' (1993). The Sharjah Seedbank & Herbarium hold records of this species from near Wahala (Sharjah) to the east near the border with Oman, from the Ras Al-Khaimah coast east at Jazirat Al Hamra, from the Sharjah-Abu Dhabi border north of Al Shwalb, and from south of Dubai city. It has also been reported from Jebel Nazwar. The native distribution of this species is from north-east Africa (Egypt to Kenya) to north-west India, and it has been introduced to the Americas (Board of Trustees, RBG Kew 2018).

(2019) show presence of this throughout the east coast. The species is recorded from the Ru'us al-Jibal, although uncertain if from parts of the mountains within the UAE, and confusion is possible with other members of the genus (Feulner 2011). Feulner (2016) considers only this species of Cymbopogon to present in Wadi Wurayah. The native range of this species is in Africa from the Sahara and the Sahel to Kenya, east through the Arabian Peninsula to Iran (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
This species is generally described as common throughout its distribution in the Ru'us al-Jibal. This may related to its ability to survive at particularly high elevations and rocky summits, where it has been described as dominant and co-dominant. However, this species appears to be severely impacted by extended periods of drought, which may become more common as a result of climate change. Therefore, it is currently assessed as Least Concern with the need to reassess as conditions continue to change.

Globally, the native range of this species spans from Turkey to Socotra and on to China (Board of Trustees, RBG Kew 2019).

Threats listed in assessment
It is thought that extended periods of drought may threaten this species, due to an observed decline in abundance within the Ru'us al-Jibal in the late 1990's (Feulner 2011).

The extent of occurrence (EOO) of this species is estimated to be less than 10,500-15,000 km<sup>2</sup> and, although it is widely scattered throughout the UAE, the number of locations is likely to be close to ten. Crotalaria persica is known to have been lost from some areas and is therefore inferred to be declining. Development, including along the coastline, is thought to pose a threat to this species, in addition to grazing by goats. Therefore, it is assessed as Near Threatened under criterion B1.

This species is known from Jebel Ali (Jongbloed et al. 2003), in addition to Jebel Hafeet, Hamriyah, Sharjah, Ras al-Khaimah and Sila in the western UAE. It was also found from Wadi Siji in 2017. Crotalaria persica is known considered to have possibly been lost from Jebel Ali, in addition to subpopulations being lost due to development. In particular, a subpopulation was lost due to construction of a radio mast (G.R. Feulner pers. comm. 2019) and the occurrence in Taweela no longer exists (G. Brown pers. comm. 2019). The estimated EOO for this species is 10,500-15,000 km<sup>2 </sup>and the number of threat-based locations is considered to be close to ten, according to the threat of development. Globally, this species is found from north-east tropical Africa to Pakistan (Board of Trustees, RBG Kew 2019).

Habitat details as listed in assessment
Crotalaria persica grows within low sand dunes (Jongbloed et al. 2003) and gravel habitats, in addition to wadis, around Jebel Hafeet. It is a perennial species which produces solitary, slightly red flowers between January to April (Jongbloed et al. 2003). This species is a crop wild relative of sunhemp, Crotalaria juncea (Kameswara Rao 2010).
Threats listed in assessment
Impacts from coastal development within this species distribution are likely to have been significant. This species is known to have been extirpated from one locality due to the construction of a radio mast (G. Feulner pers. comm. 2019). In addition, grazing by goats could present a threat within specific localities, such as Wadi Siji.
History
Increasing frequency and intensity of development, both commercial and residential, since 1996 mean that it is now listed as Near Threatened rather than Least Concern.

Assessment rationale/justification
This species is generally considered common throughout much of the eastern UAE. However, a large proportion of its range occurs along the east coast of the UAE, which is subject to ongoing development reducing the extent and quality of available habitat. Given the estimated extent of occurrence of 7,369 km<sup>2</sup>, the species potentially qualifies as Near Threatened on the basis of its restricted EOO and continuing decline in parts of its range. However it is considered here as Least Concern on the basis of its moderately wide distribution in the country and stable populations generally.

Threats listed in assessment
As this species occurs along the east coast of the UAE, it is likely to have been affected by ongoing coastal development.
History
Coastal development along the east coast of the UAE has increased since 1996, and so its Red List status is thought to have deteriorated in the intervening time.
