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 This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Taxon distribution as listed in assessment
Within the UAE, this species has been recorded from Wadi Wurayah in addition to the Hajar Mountains (Jongbloed et al. 2003, Feulner 2011), where it is known from a small number of sites such as Wadi Hayl. It is thought that it may also occur in the Ru'us al-Jibal (Feulner 2011). This species seems to be found more often at low-medium elevations (Feulner 2011). Globally, the native range for this species spans across Macaronesia, Africa and on to India (Board of Trustees, RBG Kew 2019).
