Assessment rationale/justification
In the UAE, this species is restricted to the Ru'us al-Jibal. The extent of occurrence (EOO) is highly restricted, at less than 200 km<sup>2</sup>. The AOO is a maximum of c. 180 km<sup>2</sup> but is likely to be very much less. The species is likely to be subject to grazing by livestock and feral animals, however the impact of this threat on the species is uncertain. In natural habitats, the species is generally found as single plants and the overall population size is restricted, however it may be overlooked. The species has been found recently to be more common in agricultural areas, however in natural habitats it is very much less frequently found. Whilst there is insufficient information on the plant in natural habitats, the species is precautionary assessed as Near Threatened on the basis of its known restricted EOO and suspected restricted AOO, although the number of locations (based on occurrence in natural habitats exceeds ten). It is possible that the number of mature individuals may also be restricted, and the species may also qualify as threatened or Near Threatened under criterion D.

Assessment rationale/justification
This species occurs in a distinct, restricted area within the UAE, with an estimated extent of occurrence (EOO) of 2,322 km<sup>2</sup>: this estimate falls within the threshold for threatened categories under Criterion B1. However, it occurs in at least two protected areas, with a significant part of its range occurring within the Al Ghada Protected Area. Based on the ongoing threats of grazing and development, this species is considered to occur in 10-15 locations, and also experiences ongoing habitat decline outside of its protected area range. Therefore, it is currently assessed as Near Threatened.

This annual herb can grow up to 0.3 m in height, producing pale yellow flowers on long stalks between February and April (Jongbloed et al. 2003, Norton et al. 2009). The fruit is distinctive in appearance, curved in a claw and star shape with hooked hairs. This facilitates dispersal by clinging to hair and fur of other species (Jongbloed et al. 2003). Koelpinia linearis is considered to be a halophyte i.e. salt-tolerant plant (Böer and Saenger 2006) and is typically found growing within silt environments among rocky hillsides, in addition to sand and gravel plains (Jongbloed et al. 2003).

This is an annual herb species which produces yellow flowers from January to March (Jongbloed et al. 2003, Norton et al. 2009). It grows to heights of up to 30 cm and typically occurs in silt substrate between rocks in montane areas (Jongbloed et al. 2003). This species can be found in sandy and gravelly habitats, wadis, plantations and fallow fields (MEW 2010, Feulner 2011). It is sometimes considered as a weed of disturbed areas and silty depressions within its habitat (Norton et al. 2009). It is highly rain-dependent.
Threats listed in assessment
Grazing by goats may affect this species in parts of its range (Shahid 2017). Declining rainfall is thought also be causing declines.
History
This species is considered to have become much less common due to decreasing frequency of wet years. In addition, increasing grazing may have contributed to population declines since 1996.

Assessment rationale/justification
This species is assessed as Near Threatened due to its restricted distribution. The AOO is estimated at close to 150 km<sup>2</sup> and there is still ongoing development of coastal areas within the UAE, however, the number of threat-based locations is estimated to be greater than 10. Although this species represents the dominant mangrove species and the area of mangrove habitat has actually increased in the UAE within the last 10-20 years, mangroves are still at risk from intensive coastal development. In addition, these trees have important economic and ecological value in terms of providing habitats to other species and tolerating extreme conditions. It is recommended that more of these habitats are designated as protected areas, along with ongoing planting strategies.

Taxon distribution as listed in assessment
This species occurs across the coast of Abu Dhabi and other areas of the UAE, including off-shore islands (Sakkir et al. 2017). The distribution consists of discontinuous patches along the coastline which is likely the result of coastal development (Sakkir et al. 2017). Within Abu Dhabi alone, this species is estimated to cover an area of 40 km<sup>2 </sup>(Saenger et al. 2004). Throughout the UAE as a whole, there are considered to be 60-70 km<sup>2</sup> of natural mangroves, and slightly over 150 km<sup>2</sup> of mangroves when including planted individuals (EAD 2014, H.S. Das pers. comm. 2019). The number of threat-based locations for this species is estimated to be greater than 10 due to multiple patches existing along the UAE coastlines. Its native range extends across the tropical and subtropical Old World (Board of Trustees, RBG Kew 2019).

Habitat details as listed in assessment
This mangrove species typically along the coast of the UAE in estuaries, sheltered bays and creeks (Norton et al. 2009, Beech 2009). It is characteristic of the tidal zone, muddy inlets estuaries and shallow lagoons (Patzelt 2015). Avicennia marina is currently the only species of mangrove to grow naturally within the Arabian Gulf (Böer and Saenger 2006, Zander and Bruckner 2005). It is highly tolerant towards high temperatures in addition to salinity (Beech 2009) and has been described as a 'notoriously tolerant' species (Feulner 2000). However, this species shows increased growth in lower salinity levels (Llewellyn-Smith 2011). Individual trees have been recorded to grow up to 8 m in height, but typically grow to around 4-5 m (Aspinall et al. 1995, Perry 2008). The mangrove flowers between May and June and begins to bear its almond shaped, pale green fruit from September (Jongbloed et al. 2003, Saenger et al. 2002). Holes in the trees of this species provide a home for kingfishers, Limonium axillare (Aspinall et al. 1995). They are also associated with the macrophytic green algae genus Enteromorpha (Ghazanfar and Fisher 1998). It also provides habitats for fish and crustaceans, in addition to breeding habitats for other species of bird (Perry 2008).
Threats listed in assessment
Mangrove habitats used to be much more widespread in the UAE than they are currently (Hogarth and Beech 2001). These populations were depleted through using the wood of the trees for architecture and for building boats (Hogarth and Beech 2001). These trees are grazed by camels which can reduce their overall height (Karim and Dakheel 2006), however this is not thought to be a major threat as these trees are not though to be very palatable to animals (Norton et al. 2009). Expansion of coastal areas for public recreation will threaten this species as the coastline is converted from natural habitats (Ghazanfar and Fisher 1998). Losses in mangrove habitat area from several of the Emirates have been noted in the past two decades, due to land use change and development (Moore et al. 2013). In addition, physical removal of mangroves and hydrological changes to these coastal areas as a result of creation of new islands are important threats to the grey mangrove (H.S. Das pers. comm. 2019). However, despite this potential threat, it appears that over the last 10-20 years the UAE's extent of mangrove habitats seems to have actually increased, overall (Moore et al. 2013).
History
This species is still impacted in parts of its rage from coastal development, however, conservation efforts and planting regimes have helped to increase the area occupied by this species in the UAE, in addition to facilitating an overall population increase within the species' historical range.

This perennial herb is a seagrass species (Norton et al. 2009, Phillips et al. 2002). It can grow at depths between 2-8 m (H.S. Das pers. comm. 2019).
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.

Assessment rationale/justification
This species has a restricted extent of occurrence (EOO) within the UAE and is not considered to be common within this area. The estimated EOO for this plant is around 1,430 km<sup>2</sup>, which falls within the threshold for threatened categories. The species probably occurs in more than ten threat-based locations, but the number of locations is likely to be restricted. Water abstraction and declining rainfall as a result of climate are resulting in population declines. As a result, it is cautiously assessed as Near Threatened due to the restricted distribution within the UAE and declining populations. No regional adjustment is made as the extent of any rescue effect is not known.

Taxon distribution as listed in assessment
Distribution of this species is recorded from wadis in the Hajar Mountains (Jongbloed et al. 2003, Al Mehairbi et al. 2019). Feulner (2016) did not find the species (as Eliocharis geniculata) in WWNP, but would expect it to be present. The estimated Extent of Occurrence (EOO) of this species is around 1,430 km<sup>2</sup>. Globally, this is a pantropical species (Board of Trustees, RBG Kew 2018).

Habitat details as listed in assessment
This is an annual or short-lived perennial species, up to 0.35 m (Jongbloed et al. 2003). It is usually found in moist banks of ponds and wadis (Jongbloed et al. 2003). Brackish marshes and edges of mangrove swamps are typical habitats for this species (Board of Trustees, RBG Kew 2018).
Threats listed in assessment
Declining rainfall and increases in water abstraction in recent years has resulted in population declines (G.R. Feulner pers. comm. 2019).
History
The species is assessed as Least Concern in 1996, as it was much more common at the time.

Assessment rationale/justification
This species occurs within sand and coastal habitats in the UAE and has an estimated extent of occurrence of 2,646 km<sup>2</sup>; this falls within the threshold for Endangered under Criterion B. In addition, the species' habitat is declining due to ongoing coastal development, causing the once common species to become less common in its range. However, the number of locations for this species (based on the most plausible threat of habitat degradation) is currently unclear. Therefore, it is currently assessed as Near Threatened.

Taxon distribution as listed in assessment
This plant occurs in coastal areas and in the Hajar Mountains (Jongbloed et al. 2003) and has been found to occur in Wadi Wurayah National Park, Fujairah (Feulner 2016). It also occurs at Jebel Ali along the Arabian Gulf Coast. The estimated EOO of this species is 2,646 km<sup>2</sup>. Globally, Ophioglossum polyphyllum is distributed across Africa and southwest Asia, eastwards to India and southwards to South Africa (Board of Trustees, RGB Kew 2018). In Europe it occurs only on the Canary Islands (Christenhusz et al. 2017). It is also distributed in Central America and Australia (Board of Trustees, RGB Kew 2018).

Habitat details as listed in assessment
This perennial fern species is known to grow in open sand habitats and coastal areas (Jongbloed et al. 2003, Rothfels et al. 2012). At higher altitudes, it can grow within silt rather than sand (Jongbloed et al. 2003). It has two or three elliptic leaves growing from the stem in addition to other stem like leaves (Jongbloed et al. 2003). The plant generally appears after periods of rain (Jongbloed et al. 2003).
Threats listed in assessment
This plant is reportedly threatened by development in its coastal habitat range (Jongbloed et al. 2003, Feulner 2016).
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.
