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 This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Assessment rationale/justification
The species appears to be known from a single record in the UAE from 1991. This locality may no longer exist due to its status as a temporary pool, and therefore confirmation of this species' distribution within the UAE is required prior to assessing. For now, it is considered Data Deficient.

Taxon distribution as listed in assessment
The species was collected from the UAE, in 1991, from a pool along the Sweihan Road (Abu Dhabi Emirate, c. 35 km east of Abu Dhabi International airport; Western 1992; <a href=""http://data.rbge.org.uk/herb/E00325788"">RBG Edinburgh Herbarium</a>). However, due to development in this area, it may now be the case that this temporary pool no longer exists. The species has an almost global distribution (Board of Trustees, RBG Kew 2019).
