(see Assessment details)

Assessment rationale/justification

The species is apparently known from just two records in the UAE. The origin and identification of the specimen requires confirmation, and it is considered Data Deficient here. The species is utilized as a dye in other countries, and therefore its occurrence in the UAE might be the result of use and cultivation.

The species is apparently known from Mushrif National Park (now a suburban park, but originally a traditional oasis where remnant native flora were found) in Dubai (coll. K. Müller-Hohenstein, 1986; <a href=""http://data.rbge.org.uk/herb/E00450010"">RBGE Herbarium</a>). The species is also known from a locality near the Emirates Road in Sharjah (Sharjah Seedbank & Herbarium record). The origin and distribution of the species within the UAE requires confirmation. The global range of this species is circum-Mediterranean, through much of the Arabian Peninsula, east to India and north to Central Asia (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification

The distribution of this species in the UAE is apparently not well documented, possibly as a result of confusion with Schismus barbatus, and it appears to be known from a very small number of records in the Hajar Mountains and Jebel Hafeet. This almost certainly does not represent its full range in the UAE, and recent surveys confirm that the species is abundant in deserts in the northern Gulf (G. Brown pers. comm. 2019). It is considered Data Deficient pending further information on its distribution.

The species is mentioned by Jongbloed et al. (2003) without details. The species has been recorded from Jebel Hafeet (Sakkir and Brown 2014) and from Fujairah (RBG Edinburgh Herbarium; Jebal Ruwaydah at the head of Wadi Sidakh). More recent surveys confirm that the species is abundant in deserts in the northern Gulf (G. Brown pers. comm. 2019). The native range of this species is along Mediterranean coastal countries of North Africa to Ethiopia, and the eastern Mediterranean (from Greece eastwards), through the Arabian Peninsula, to Mongolia (Board of Trustees, RBG Kew 2019). The species has become widespread and invasive in arid and semi-arid regions of North America and Australia (CABI 2019).

This is a small, tufted annual grass that grows up to 0.2 m in height (CABI 2019). As a desert annual, it can be absent for many years and only appear, or are more conspicuous, in particularly wet seasons (Sakkir and Brown 2014). MEW (2010) recorded the habitat as dry wadi banks and beds, whilst the RBG Edinburgh record was from a north-facing limestone hillside.

The species has a wide global distribution through Africa and southern Europe to East Asia (Board of Trustees, RBG Kew 2019). The species is found throughout Oman (in sandy and rocky wadis, beside roads, near cultivation, and in disturbed and waste ground; S. Ghazanfar pers. comm. 2019).

Its range extends into the northern Hajar Mountains, and an unidentified Galium species has been recorded from Wadi Wurayah National Park (Feulner 2016). The origin of the species in the UAE requires confirmation, and the species is considered introduced to the UAE by MoCCaE (O. Al Shamsi pers. comm. 2018). The global native range of this species is obscure and it is considered to be be very widely introduced and naturalised (GRIN 2019). Plants of the World Online considers it to be native to Europe, northern Africa and temperate and tropical Asia (Board of Trustees, RBG Kew 2019). It has also been introduced to the Americas, Greenland and Australasia (Board of Trustees, RBG Kew 2019).

This annual species has slender stems and can reach up to 0.5 m in height (Jongbloed et al. 2003). It climbs on surrounding vegetation and has downward pointing prickles on both the spines and the leaf whorls, which give the plant a 'sticky' feel (Jongbloed et al. 2003). The fruit is a round, hairy capsule and the small white flowers can be seen between February and April (Jongbloed et al. 2003). It generally grows within mountain wadis and in plantations (Jongbloed et al. 2003). G.R. Feulner (in litt, MEW 2010) notes that it is found in the same habitats as G. ceratopodum, in the foothills and wadis, on silty soils amongst stones and near water channels and runnels.

This species is known from one site within the Ru'us al-Jibal. The species occurs at high elevations and are relatively undisturbed sites, which this plant appears to prefer. In addition, it is generally described as rare and detailed distribution data is lacking for this species. It would benefit from further research into its tolerance of threats, including disturbance, in addition to confirming its overall distribution in the UAE to be able to accurately assess it. For now, it is assessed as Data Deficient and further research is needed for this species.

Taxon distribution as listed in assessment

Avena barbata occurs in the Ru'us al-Jibal mountains in the north of the UAE (Jongbloed et al. 2003, Feulner 2011). Within this area, it has been recorded from one confirmed locality in the UAE at 900 m elevation, above bedrock on a ridge. A second record at 1,500 m elevation (Feulner 2011) may not be within the UAE. The origin and distribution of the species in the UAE requires confirmation; it may be native or be present here as a result of natural introduction, or may have been introduced alongside agriculture. Globally, this species occurs in northern, middle, east, south-east and south-west Europe, temperate Asia, Macaronesia, northern Africa and the Indian Subcontinent, and is naturalized in the Azores, Australia and the Americas (Duarte et al. 2011, Board of Trustees, RBG Kew 2018).

Avena barbata is a tall and thin grass (Jongbloed et al. 2003) known to occur in one site in the Ru'us al-Jibal in the UAE. Globally, Avena barbata has been reported to be very successful in undisturbed sites, preferring shallow stony hillsides, open parkland, pastures and cultivated land. It does not favour shrubby or forested sites (Duarte et al. 2011). In the UAE, it was found in silt amongst rock, on bedrock on ridge, c. 0.2 km above cultivation (Feulner 2011, G.R. Feulner pers. comm. 2019). This species is a crop wild relative of the oat crop, Avena sativa (Kameswara Rao 2013).
