Assessment rationale/justification
In the UAE, this species is found along the Arabian Gulf coast. The estimated EOO of this species is 779 km<sup>2</sup> and is estimated to occur at three threat-based locations. Echiochilon jugatum is undergoing a continuing decline in the extent and quality of its habitat due to ongoing coastal development in the UAE. For example, the Taweela subpopulation of this species has now been lost due to the construction of an aluminium plant. Therefore, it is assessed as Endangered.

Taxon distribution as listed in assessment
In the UAE, this species is found along the Gulf coast, including Ras al-Khiamah (Jongbloed et al. 2003, MEW 2010) although Hornby (2005), who previously found the species at Taweela, considered it to be a ""very thinly spread"" species. The estimated EOO of E. jugatum is 779 km<sup>2</sup> and is considered to occur at three locations based on ongoing degradation and development. The global range of this species is through the Arabian Peninsula from sea level to 200 m asl in Bahrain, Qatar, United Arab Emirates, Oman (Långström 2002), and Saudi Arabia (Norton et al. 2009).

It is a perennial shrublet that grows on sand (Långström 2002). In the UAE, the species is found on coastal saline soils (MEW 2010).
Threats and conservation measures listed
Threats listed in assessment
This species has been impacted by continuing coastal development in the UAE. For example, the subpopulation previously found at Taweela has now been lost due to construction of an aluminium plant (G. Brown pers. comm. 2019).
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.

IUCN

(see Assessment details)

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.

(see Assessment details)

Assessment rationale/justification
This species is considered to be rare within its range and is often grazed to the point of visibly stunted growth. This may pose a significant threat to the species, however the full extent of this is still unclear. Although the species occurs in a National Park, it is important to draw attention to this potentially threatened and rare species. As a result, it is cautiously assessed as Vulnerable (D1) as a result of the small number of mature individuals, which is suspected to be close to or less than 1,000, but no reliable count has been made. It also has a restricted distribution (estimated EOO: 6,378 km<sup>2</sup>). The species occurs in adjacent parts of Oman and the seed is wind-dispersed, therefore the assessment is revised down by one category to Near Threatened.

It has been recorded at altitudes up to 1,900 m (Feulner 2011). The estimated extent of occurrence (EOO) of this species is 5,714 km<sup>2</sup>. Individual records include the upper parts of Wadi Sfai (M. Tsaliki pers. comm. 2019). It has also been recorded from Jebel Hafeet and from the Al Ain area.

This is a perennial or annual succulent that grows up to 35 cm (Western 1992, Jongbloed et al. 2003). It produces purple flowers between February and May, in addition to characteristic pickle-shaped fruit, and grows among rocks, gravel plains, wadis and mountains (Jongbloed et al. 2003, Feulner 2016). When the plant is damaged, it secretes milky sap (latex) which is characteristic of Asciepiadaceae species (Western 1992). The species is considered to be a xerohalophyte i.e. a salt-tolerant desert species (Böer and Saenger 2006).
Threats and conservation measures listed
Threats listed in assessment
This species is may be difficult to identify as the plant is often grazed to the point of a very stunted growth form (Western 1992) and fruits are consumed by people.
History
The situation is not thought to have changed for this species since 1996.

Assessment rationale/justification
This species has a fairly restricted distribution within the UAE and is considered to be rare, even within its range. The estimated EOO and of this species is 261 km<sup>2</sup> which falls within the threshold for threatened categories. Based on this restricted distribution and the possibility of collection from the wild for cultivation, in addition to the rarity of the species, the species is assessed as Endangered, with the number of mature individuals suspected to be fewer than 250. No rescue effect is likely, with the nearest populations some distance away in Oman.

This is a perennial shrub that grows up to 80 cm (Reza Khan 1992). It flowers throughout the year but peaks between January and May (Jongbloed et al. 2003). It is a poisonous plant that grows in gravel and sand plains as well as wadis (Drew 2000, Jongbloed et al. 2003, Mahmoud et al. 2018). Its presence is known to be a sign of overgrazing as livestock avoid eating it, and so it becomes dominant in grazed areas (Feulner 2011, 2016). However, the flowers of this plant are known to be utilised by adult Plain Tiger butterflies (Gillett 1998).

Assessment rationale/justification
This species appears to be known from a single record from Hatta in the northeast of the UAE. Aside from this locality, there is little other information available on this species within the UAE. In addition, it is possible that records of Galium tenuissimum may have been confused with other related Galium species. Therefore, it is currently assessed as Data Deficient.

Assessment rationale/justification
Much of the published literature on Tamarix passerionoides refers to this species under the synonym, Tamarix aucheriana. In order to accurately assess this species, it's important to determine whether these plants are indeed two distinct species and, if so, determine a detailed distribution for T. passerionoides under its own name to effectively assess its risk of extinction in the UAE. For now, it is assessed as Data Deficient pending further research into its taxonomy.

Taxon distribution as listed in assessment
There is little information available for this species in terms of distribution in the UAE, however, Tamarix aucheriana is considered to occur in saline areas within the country. Globally, this species is native to northern Africa and temperate Asia (Board of Trustees, RBG Kew 2019). Plants of the World Online doesn't list the UAE as a native country of occurrence for this species, and Norton et al. (2009) state that this species is not found in other Gulf States except for Qatar.
