The National Red List Project

Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Species
Taxon distribution as listed in assessment
Within the UAE, this species has only been recorded from a single location: coastal sands close to Khor Fakkan, by G.R. Feulner (Jongbloed et al. 2003, MEW 2010). The estimated extent of occurrence of this species is 4 km<sup>2</sup>. Despite the locality undergoing change, the species persists (G.R. Feulner pers. comm. 2019). Globally, the native range of the species spans from Tanzania to Egypt and the Arabian Peninsula, to Pakistan and India (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
This species is restricted to a single location within the UAE. It is rare, with no more than 25 mature individuals seen, and is now thought to be threatened by human disturbance as a result of improved access to the area for leisure activities, such as hiking. Based on this, the species habitat is inferred to decline in quality. This decline, combined with an estimated extent of occurrence (EOO) and area of occupancy (AOO) of 4 km<sup>2</sup>, this species is assessed as Critically Endangered (CR B1ab(iii)+2ab(iii), D). The species is also considered threatened elsewhere in the Gulf region, and no regional rescue effect is applied.

Conservation
Threats listed in assessment
The site where this species is found has recently become more accessible to tourist activities and human disturbance (G.R. Feulner, in litt, MEW 2010), including management for amenity use. This may negatively impact the species, although it is unclear to what extent.

History
The population is thought to have always always been small (and hence qualify as CR), although the declines are more recent.
