Assessment rationale/justification
Fewer than ten individuals are known from a single location in the UAE. Therefore, Cordia quercifolia is assessed as Critically Endangered (CR D). There is no reason to doubt the native origin of the species in the UAE, despite the species being known from abandoned agricultural areas, as the species is not known to be associated with agricultural areas elsewhere.

Assessment rationale/justification
This species is restricted to a single location within the UAE. It is rare, with no more than 25 mature individuals seen, and is now thought to be threatened by human disturbance as a result of improved access to the area for leisure activities, such as hiking. Based on this, the species habitat is inferred to decline in quality. This decline, combined with an estimated extent of occurrence (EOO) and area of occupancy (AOO) of 4 km<sup>2</sup>, this species is assessed as Critically Endangered (CR B1ab(iii)+2ab(iii), D). The species is also considered threatened elsewhere in the Gulf region, and no regional rescue effect is applied.

Guidelines for Application of IUCN Red List Criteria at Regional and National Levels: Version 4.0. Gland, Switzerland and Cambridge, UK: IUCN. iii + 41pp.
Assessment rationale/justification
This species has a very restricted distribution within the UAE, having only been recorded from Jebel Qitab and Wadi Hayl. Its estimated extent of occurrence (EOO) is 24 km<sup>2</sup> and area of occupancy (AOO) is 8 km<sup>2</sup>. According to the most important threat to this species (drought and extreme weather), it is considered to occur at one threat-based location. In addition, this species is experiencing an ongoing decline in the extent and quality of available habitat due to ongoing droughts and grazing by animals. Therefore, this species is assessed as Critically Endangered (CR B1ab(iii)+2ab(iii)). There is not considered to be any rescue effect from subpopulations in Oman, meaning that no regional adjustment is required for the assessment and it remains as Critically Endangered.

Taxon distribution as listed in assessment
This species has been recorded from slopes within the north-east of Jebel Qitab (Feulner 2011) and from nearby Wadi Hayl in 2015 (Sharjah Seedbank & Herbarium) in the Olive Highlands. The species appears to be restricted to this specific habitat within the UAE (Feulner 2011), however it is also found in Ru'us al-Jibal in northern Oman (Jongbloed et al. 2003), e.g. the Wadi Khaab Shamsi gorge in Oman. Generally, the species is found in a few scattered montane locations (Jongbloed et al. 2003, MEW 2010) in the region. The native range for this species extends from the Sahara to Tanzania and the Arabian Peninsula, in addition to from southern Africa to the Indian subcontinent (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
The only records of this species within the UAE are from to adjacent wadis in northern Ras al Khaimah, where a few scattered individuals are reported (Feulner and Roobas 2013). The total number of mature individuals is inferred to be less than 50. The species also occurs in the Ru'us al-Jibal at lower altitudes (Feulner 2011), however confirmation of presence within the UAE is required as its possible that these occurrences are the result of cultivation, due to most or all occurring in anthropogenic habitats. Based on the occurrence in the Wadi Ghalilah area, the extent of occurrence (EOO) and areas of occupancy AOO) are likely to be highly restricted, however these metrics have not been estimated as detailed locality records are not available. Based on the number of mature individuals being inferred to be less than 50, the species is assessed as Critically Endangered (CR D) and it is likely that the species may also qualify for a threatened category under criterion B based on the probably restricted EOO and AOO. Further research and survey work is needed for this species to confirmation its distribution, origin, and population status. No rescue effect from populations in Oman is considered likely because the nearest known populations are in Oman close to Al Ain.

Jongbloed et al. (2003) recorded this species within the UAE from four very localised records in the Wadi Ghalilah and Wadi Sha'am, in the area of northern Ras al Khaimah by Allestree Fisher (Karim and Fawzi 2007, G.R. Feulner, in litt, MEW 2010, Feulner and Roobas 2013). The species also occurs in Oman in the Ru'us al-Jibal at lower altitudes (Feulner 2011), where it is common. Feulner (2011) notes that the main range of the species in the eastern Arabian Peninsula is south of the Al-Ain/Buraimi area, outside of the UAE. The species occurs close to Al Ain in Oman, at Jebel Qatar, and especially from Wadi Jizzi southwards (Feulner 2016). Globally, this species is distributed across Africa, through the Arabian Peninsula, to Iran and Pakistan (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
This species was first recorded for the UAE in 1996; this single know location at Jebel Qitab, from c. 650 m to c. 1,000 m asl, still remains. The species has an extent of occurrence (EOO) and an area of occupancy (AOO) of less than 20 km<sup>2</sup> and occurs in one location, based on drought and the potential threats of grazing. G.R. Feulner (in litt, MEW 2010) reported a maximum of 30 plants, perhaps fewer than 20, and there was little or no regeneration seen. The species is assessed as Critically Endangered (CR D) based on the number of mature individuals being less than 50. Whilst the species occurs at other sites within the Hajar Mountains in Oman, it is thought that there is little opportunity for a rescue effect, and the assessment remains CR.

This species was first recorded for the UAE in 1996 from cliffs on Jebel Qitab at c. 1,000 m asl (Feulner 1997) and this remains the single known site for the species in the UAE. The species is locally common at a small number of localities above c. 800 m elsewhere in Hajar Mountains in Oman (including Jebel Akhdar and Jebel Ghaweel; Feulner 1997). It is absent from the Ru'us al-Jibal in the UAE (Feulner 2011). The species has an EOO and an AOO of less than 20 km<sup>2</sup>. Jongbloed et al. (2003) show the species in the Wadi Khabb Shamsi gorge, in Oman. The native range of this species is from southern Africa, through the Arabian Peninsula, to northwestern India (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
This species is the only reptile currently known to be endemic to the United Arab Emirates. It is only known from two localities along a narrow strip of the east coast of the United Arab Emirates. No specimens have been recorded from the type locality (near Khor Fakkan, Emirates of Sharjah) since 1973, with the only recent records being from a second known locality, a few kilometres further north of Sharm, Emirates of Fujairah. The only confirmed specimens that have been found in the past 45 years are therefore restricted to the second locality and the species is consequently considered to survive at a single location defined by the threat from development. It is possible that the species occurs in other potentially suitable habitats along the same coastal stretch, or persists at the type locality, and additional survey in these areas is urgently required. The species has been found between sea level up to 20 m in elevation. Both the extent of occurrence (EOO) and the area of occupancy (AOO) are estimated at 8 km<sup>2</sup> based on a 2x2 km grid drawn around the two localities, however both the EOO and the AOO are in reality very much more restricted, with the species found on isolated rocky outcrops and presumed to have been lost from one of these.The species is listed as Critically Endangered (CR B1ab(iii,v)+2ab(iii,v)) as a result of its restricted EOO and AOO, with both of the known localities, as well as areas along the east coast of the United Arab Emirates with apparently similar habitat characteristics, under heavy transformation or have already been converted for industrial, residential or tourist development. The species is currently considered to persist at a single location defined by the described threats, which are resulting in a continuing decline in the extent and quality of this species' habitat, and inferred to be causing a continuing decline in the number of mature individuals.Conservation actions are urgently required for this species, including ex situ conservation, and the potential for the establishment of new sub-populations should be investigated.

This species is only known from two localities along a narrow strip of the east coast of the United Arab Emirates: the type locality at Jebel Ra's, 2.5 km south of Khor Fakkan, Emirates of Sharjah; and a second locality (named ""locality 29"" by Carranza et al. 2016) a few kilometres further north of Sharm, Emirates of Fujairah. No specimens have been recorded from the type locality since 1973, and it is considered likely to have been extirpated from this locality (see Threats). Consequently, the only confirmed specimens that have been found in the past 45 years are restricted to the second locality. It is possible that the species occurs in other putatively suitable areas of the same coastal stretch that have not been surveyed as a result of restricted access due to development. The species has been found between sea level up to 20 m in elevation.

Taxonomic Notes

Taxonomic Notes
A recent systematic revision by Carranza et al. (2016), using an integrative approach including molecular (mitochondrial and nuclear markers) and morphological data, indicated that the species originally classified as Asaccus caudivolVulnerablelus (Arnold and Gardner 1994, Gardner 2013) was an assemblage of three different species that started diversifying during the Mid-Miocene. The analyses uncovered a very old diversification event that resulted in a case of microendemicity, where three morphologically and ecologically similar medium-sized species previously classified within A. caudivolVulnerablelus coexist in a very short and narrow mountain stretch.As a result of this study, two new species -“ A. gardneri and A. margaritae -“ were described, both of them widely distributed across the northern tip of the Hajar Mountains. Conversely the third species - Asaccus caudivolVulnerablelus sensu stricto - appears to be restricted to a small coastal area of the United Arab Emirates under heavy development, where the only two localities in which the species has ever been recorded occur. The molecular analyses indicate that A. caudivolVulnerablelus has been evolving independently from its sister taxon, A. gardneri, for approximately four million years.

Assessment rationale/justification
This species has a small non-breeding population that would warrant a listing as Endangered under criterion D. However, the species is thought to have previously bred in the UAE, and the breeding status takes precedence here. The species is suspected to no longer be a breeding species in the country, but lack of sufficient survey work to confirm its disappearance from the whole country means that it is tentatively treated here as being still extant. Any remaining breeding population is still thought to be tiny. Therefore, the species is listed here as Critically Endangered under criterion D.

Taxon distribution as listed in assessment
The majority of occurrences of this species within the UAE are likely to be of migrant individuals on passage to and from the breeding grounds in September-November and March-April (Richardson 1990, Pedersen et al. 2017). It is also a common wintering bird in the country (Pedersen et al. 2017). Since 1993, there was a small resident population of about 20 pairs in the UAE, which bred on Taweela Island/Ras Ghanada (Abu Dhabi) and Siniyah Island (Umm al-Quwain), as well as along the coast from Umm al-Quwain to Ras al-Khaimah emirates (Richardson and Aspinall 1998, Jennings 2010, Pedersen et al. 2017). However, it is now believed that the species no longer breeds regularly in the UAE, if it still breeds at all (R. Sheldon;in litt.;2019). There hasn't been sufficient surveying work, though, to confirm its disappearance from the country as a breeding species, and it is quite possible that there could be individuals breeding in unsurveyed areas. Therefore, for this process it is tentatively treated as being still extant.

The majority of occurrences of this species in the UAE are of migrating individuals on passage to and from the breeding sites. The abundance is highest in early April and in mid-August to November (Pedersen et al. 2017). It occasionally winters in the country, but numbers vary (Richardson 1990, Jennings 2010). It was thought to be likely that at least 5-20 pairs regularly breed in the country (Jennings 2010, Pedersen et al. 2017), but it is now believed that the species may no longer breed regularly in the UAE (R.

Calandrella brachydactyla and C. dukhunensis (del Hoyo and Collar 2016) were previously lumped into C. brachydactyla following AERC TAC (2003), Cramp et al. (1977-“1994), Dowsett and Forbes-Watson (1993), and Sibley and Monroe (1990, 1993).Closely related to C. cinerea, with which often previously merged, and to C. blanfordi, C. eremica and C. acutirostris; until recently considered conspecific with C. dukhunensis (see related note). Geographical variation slight and clinalà¢Ã¢â€šÂ¬becoming paler and greyer to E, more rufous and streaked above to Wà¢Ã¢â€šÂ¬but greatly complicated by strong influence of wear, considerable individual variation and lack of natural boundaries; described ranges of listed taxa somewhat arbitrary. We follow Donald and Alström (in prep) in treating Greater Short-toed Lark as monotypic, finding no support for the usually accepted subspecies woltersi, hungarica, hermonensis, rubiginosa, artemisiana and longipennis. Note that the breeding range does not extend so far east into Mongolia as previously thought, indeed it is unclear whether it occurs in Mongolia at all. The species is monotypic.

Assessment rationale/justification
This species has an extremely small breeding and non-breeding population in the UAE, with an unknown population trend. This qualifies it for listing as Critically Endangered. In the wider Arabian Peninsula, the subspecies referred to as 'Peregrine Falcon' is considered to be stable or increasing, while the much more common subspecies, 'Barbary Falcon', is in rapid decline, indicating that conditions outside of the UAE might be deteriorating for the species. Therefore, the species is retained as Critically Endangered at the national level.

Taxon distribution as listed in assessment
This species is uncommon in the UAE, and is a rare breeding resident (Pedersen et al. 2017). The majority of occurrences are of migrants on passage to and from the breeding grounds, as well as of individuals from northern Europe and Russia overwintering in the country (Richardson 1990, Pedersen et al. 2017). A considerable number of individuals may be escaped or released falconry birds (Richardson 1990, Pedersen et al. 2017).
