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).

Habitat
Habitat details as listed in assessment
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.
