(see Assessment details)

Assessment rationale/justification

This species occurs at high elevations within the Ru'us al-Jibal. Although it is not as common as other species in the north of this area, this may be due to being overlooked and as a result of occurring at particularly high altitudes. It is, however, described as locally common within the south of the region. As such, it is assessed as Least Concern.

Taxonomic notes and synonyms listed

Avena barbata Link is a secondary wild relative of oats, Avena sativa L. and A. byzantina K. Koch. (A. Katsiotis pers. comm. 2010). Five subspecies are native to Europe: A. barbata Link subsp. barbata, A. barbata subsp. castellana Romero Zarco, A. barbata subsp. hirtula (Lag.) Tab. Morais, A. barbata subsp. lusitanica (Tab. Morais) Romero Zarco and A. barbata subsp. wiestii (Steud.) Mansf. (Valdés and Scholz; with contributions from Raab-Straube and Parolly 2009).Romero Zarco (pers. comm. 2015) considers Avena saxatilis to be valid as a subspecies of Avena barbata (as Avena barbata subsp. castellana Romero Zarco), a situation that Euro+Med (2015, citing Valdés and Scholz 2009) agree with. Similarly, Loskutov and Rines (2011) consider A. saxatilis to be a form of Avena barbata. However, The Plant List (2015) considers Avena saxatilis to be a valid taxon).

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).

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.

Despite being described as 'rare' within the Hajar Mountains, this species is actually a weed species. As such, it is considered frequent further inland in the Al Ain locality. It is also able to persist at a range of elevations (from sea level to 800 m) and globally it is known to persist in a variety of habitats including roads, fields, coastal areas and gravel/and substrates. Further, it may well occur within the Jebel Hafeet protected area. Therefore, it is assessed as Least Concern.

Threats and conservation measures listed

Threats listed in assessment

This species is particularly susceptible to coastal development but can recover quickly if disturbance ceases and conditions improve. It can also be affected by siltation and sedimentation (Short et al. 2010, Erftemeijer and Shuail 2012). In the UAE, the species is impacted by coastal dredging and land reclamation and development, fish trawling activities, oil spills and oil pollution, oil extraction developments, coastal water eutrophication and salinisation (from water desalination plants), siltation, and other forms of pollution (Erftemeijer and Shuail 2012). Given its shallow water habitat, this species may also be threatened by climate change and the associated increase in storm activity, water temperature, and/or sea-level rise (Short et al. 2010).

History

Coastal development within the UAE has been increasing in frequency and intensity since 1996, reducing the extent and quality of available habitat for this species.

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.
