Assessment rationale/justification
This species grows within urban and artificial habitats, such as roadsides and fields. As a result, this may make it more tolerant to urban expansion and land use change. However, as it is currently considered to be rare and is only known from one locality, more information is needed to be able to confidently assess this species. Therefore, it is currently Data Deficient.

Assessment rationale/justification
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).

Habitat details as listed in assessment
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).

Taxon distribution as listed in assessment
The species is widespread in the eastern half of the UAE and is also present on offshore islands (Jongbloed et al. 2003). The species has not been found in the Ru'us al-Jibal, however, it may exist in the mountains (Feulner 2011). Al Mehairbi et al. (2019) show a much broader and more continuous distribution, extending west well into Abu Dhabi Emirate. The species is considered introduced to the UAE by MoCCaE (O. Al Shamsi pers. comm. 2019) and by Al Mehairbi et al. (2019). The species is widely distributed across the globe (Board of Trustees, RBG Kew 2019). It is found in south-east Europe, North Africa, Macaronesia, the western Indian Ocean, Asia (Arabia, China, India, Indochina, Malaysia, and Papua New Guinea). It is considered to be introduced to Australia, the Pacific, and the Americas (Board of Trustees, RBG Kew 2019). The native distribution of this species is uncertain, although it is considered native to Africa (Heuzé et al. 2015) and perhaps the Near East.

Taxonomic notes and synonyms listed
This is a very variable species, particularly in West Africa where Hooper and Napper (1972) recognised three varieties. These were the typical variety, var. dichotoma, var. pluristriata (C.B. Clarke) Napper and var. laxa (Vahl) Napper. These subspecies and varieties have been recognised by different authors. Var. pluristriata was given subspecific rank by T. Koyama as Fimbristylis dichotoma subsp. podocarpa (Nees) T. Koyama, while var. laxa is at present on WCSP sunk into the typical species Fimbristylis dichotoma subsp. dichotoma. In some regions of Africa, namely South Africa and the area covered by the Flora Zambesiaca, Fimbristylis dichotoma is not as variable and the nutlets are entirely tuberculate like those of the typical variety as seen in West African countries.

This is also emphasised by the lack of specimens in neighbouring Oman. Globally, this species is known from the tropics and subtropics across the world (Board of Trustees, RBG Kew 2019).

Taxon distribution as listed in assessment
In the UAE, this species is known from the Hajar Mountains and from the Mazyad Oasis close to Jebel Hafeet (Jongbloed et al. 2003, M. Jongbloed pers. comm. 2019). Globally, the species occurs as a native species throughout most of Africa and around the Mediterranean basin, and has been very widely introduced across Asia and to the Americas (Board of Trustees, RBG Kew 2019). It is not listed as occurring in the UAE by Plants of the World Online, and is also considered doubtful for Oman.

Assessment rationale/justification
This species is a recent record for the UAE, where it has been found from a number of anthropogenic dam sites (Mahmoud et al. 2016), almost all of them created since the late 1990s. The species might occur naturally in the UAE, as either a recent introduction (e.g., carried by wetland birds) or have been present but not previously identified, and it is possible that the species population and range has expanded in recent years with the increase in available habitat. The origin and distribution of this species in the UAE requires confirmation, and it is therefore assessed as Data Deficient pending this.

Taxon distribution as listed in assessment
This species is recently reported for the UAE, with records from Fujairah (Wadi Ham dam), Ras Al Khaimah (Wadi Al Qowr dam, Wadi Al Mansab dam, Wadi Al Mudaynah dam, Wadi Shawkah dam, Wadi Al Qasheesh dam, and Wadi Sfini dam) (Mahmoud et al. 2016). The native range is of this species is given as tropical and subtropical Old World by Plants of the World Online (Board of Trustees, RBG Kew 2019). Mahmoud et al. (2016) give the native range as Eurasia and Africa, stating that the species has become widespread in tropical, subtropical and warm-temperate areas worldwide (El-Hamidi et al. 1967). Regionally, it has been recorded in Saudi Arabia, Oman, Yemen and Socotra, as well as the UAE (Mahmoud et al. 2016).

Habitat
Habitat details as listed in assessment
In the UAE, the species was found growing in occasionally inundated areas in wet clay soils in the front of dams and 'water breakers' (Mahmoud et al. 2016). It grows as a prostrate to spreading annual or short-lived perennial, up to 0.5 m high (Mahmoud et al. 2016). The native habitat includes temporary pools with clay bottoms and the beds of temporary rivers, canal banks, and moist ground where soils are inundated in winter and dry up in early summer (El-Hamidi et al. 1967).
