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.

The species was not recorded in the UAE in 1996 but it is possible that the species was present either in the seedbank or as underground rhizomes, or simply not found, or identified, in surveys. We consider that it is likely to have been present but in similarly small numbers, and would have qualified as CR in 1996.

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.

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
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.

Jongbloed et al.

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
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.

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.

The species is currently considered to be restricted to an isolated rocky outcrop along the Hajar Mountains on the eastern coast of the United Arab Emirates. It occurs from sea level up to 20 m in elevation and appears to prefer sea-facing rock cliffs with large boulders. It is strictly nocturnal: all specimens have been seen during the night and avoided surveyors' torch beams, retreating into crevices and holes or fleeing across boulders. Females breed year-round, laying a single egg multiple times a year.

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.
Taxon distribution as listed in assessment
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.

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.

Threats listed in assessment
The only locality where an extant population has been confirmed is under severe transformation (Carranza et al. 2016 shows an image of the locality with construction machinery in the foreground) and is zoned for development and road construction. The site is subject to dynamite blasting as part of the construction and is already under heavy transformation. This may be one of the only areas retaining suitable habitat for this species.The type locality, a mountain outcrop, is surrounded by quarrying, industrial development and harbour (importation port) which destroyed most of the suitable habitat for the species. Access to the area due to the harbour and quarrying activities is now restricted, which prevents surveys at the type locality.Marine pollution, primarily oil pollution, is an additional likely threat, with significant numbers of oil spoils known in the area.

This species occurs on open plains of sand or gravel, covered with a dense layer of grasses and herbs (Jennings 2010). It is often found on cultivated areas, near rain pools and on saltflats (Jennings 2010, Aspinall and Porter 2011). It avoids areas with dense vegetation of bushes and trees, and is rare in rocky deserts and on hillsides (Jennings 2010). It is often found in association with other larks, especially the Greater Short-toed Lark Calandrella brachydactyla (Jennings 2010). In winter, the species can form flocks of up to several thousand individuals (Jennings 2010). There is no information available on its diet in the UAE. Elsewhere, the diet varies seasonally between invertebrates and seeds. In the spring it feeds mostly on invertebrates and in winter mostly seeds with a mix of the two consumed in summer. Fruits and bulbs are also taken. The breeding season lasts from February to August. The nest is a small scrape on the ground beside a small shrub or tuft, or in the open and lined with vegetation. Normally four to five eggs are laid.

Taxonomic Notes
Calandrella rufescens (AERC TAC [2003]; Cramp et al. [1977-1994]; Dowsett & Forbes-Watson [1993]; Sibley & Monroe [1990, 1993]) and C. cheleensis (Sibley & Monroe [1990, 1993]) have been lumped into Alaudala rufescens following del Hoyo and Collar (2016).
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.

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.

Conservation
Threats listed in assessment
Development around Ras Ghanada could encroach on breeding sites, but this was thought to be likely to only have a negligible impact on the population, and Aspinall (1996) believed that unless there is to be any significant change in land-use in the near future it is unlikely that the species will face any severe threats. Given that the species has now potentially gone extinct within the UAE as a breeding species either Aspinall (1996) underestimated the impact of development on this species or there are further unidentified threats that have driven the species's potential disappearance as a breeding bird in UAE. Predation by cats,;Felis catus,;has been noted to cause local declines on the Arabian Peninsula for Crested Lark (Symes;et al.;2015), and this is another possible threat to this species.

History
It is assessed that in 1996, the national Red List status of this species would have been the same as in this assessment, as while there was still confirmed breeding in 1996, the population size would still likely have met the thresholds for listed as Critically Endangered.

Habitat
Habitat details as listed in assessment
During migration and winter, it is found in semi-desert plains (Jennings 2010, Aspinall and Porter 2011). During the breeding season, it favours lush vegetation, like cultivated and irrigated zones which experienced above average rainfall during the previous winter (Jennings 2010). During migration, it can form flocks of up to 5,000 individuals, which cross the country in April and August-November (Jennings 2010, Pedersen et al. 2017). It feeds on the ground and in low vegetation. There is no information available on its diet in the UAE, but elsewhere it feeds mainly on invertebrates, supplementing them with seeds and the green parts of plants (Jennings 2010). Little is known about its breeding biology in the UAE and Arabian Peninsula. The breeding period may last from March to June (Jennings 2010). Elsewhere, the nest is built by the female, of grasses, rootlets and similar vegetation, lined with softer material and placed in a shallow scrape on the ground, usually beside a shrub or grass tuft. It often has a small rampart of sticks or stones. Clutch size is about three eggs in Arabia (Jennings 2010).

Taxonomic Notes
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.
Taxon distribution as listed in assessment
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. Sheldon;in litt.;2019). Any remaining breeding population is still thought to be tiny, but there have been recent reports of individuals in suitable habitat in the breeding season.

Threats listed in assessment
Within the UAE, predation by cats,;Felis catus,;has been noted to cause local declines on the Arabian Peninsula for Crested Lark (Symes;et al.;2015), and this is another possible threat to this species. Overgrazing outside of Protected Areas could also pose a threat. As a migratory species, individuals that over-winter in UAE but breed elsewhere may be subject to threats outside of the country too - although the scope and severity of impact on the UAE population is essentially unknown. From BirdLife International (2015), in Europe the main threats to the species are from agricultural intensification (leading to loss of fallows, increased number of irrigation schemes, increase in surface area covered by crops, etc.), afforestation of wastelands (de Juana;et al. 2012), and residential expansion (Tucker and Heath 1994).
