Assessment rationale/justification

The EOO is estimated at around 900 km2, which falls within the threshold for threatened categories. However, there is little information on threats to this species, making it difficult to estimate the number of locations or ascertain whether it is experiencing a continuing decline. As a result, this species is assessed as Near Threatened (B1a+2a; D1) due to its restricted distribution and the probability that the population size is small. No regional adjustment is made.

This species is known from Jebel Ali (Jongbloed et al. 2003), in addition to Jebel Hafeet, Hamriyah, Sharjah, Ras al-Khaimah and Sila in the western UAE. It was also found from Wadi Siji in 2017. Crotalaria persica is known considered to have possibly been lost from Jebel Ali, in addition to subpopulations being lost due to development. In particular, a subpopulation was lost due to construction of a radio mast (G.R. Feulner pers. comm. 2019) and the occurrence in Taweela no longer exists (G. Brown pers. comm. 2019). The estimated EOO for this species is 10,500-15,000 km2 and the number of threat-based locations is considered to be close to ten, according to the threat of development. Globally, this species is found from north-east tropical Africa to Pakistan (Board of Trustees, RBG Kew 2019).

Crotalaria persica grows within low sand dunes (Jongbloed et al. 2003) and gravel habitats, in addition to wadis, around Jebel Hafeet. It is a perennial species which produces solitary, slightly red flowers between January to April (Jongbloed et al. 2003). This species is a crop wild relative of sunhemp, Crotalaria juncea (Kameswara Rao 2010).

Threats and conservation measures listed

Threats listed in assessment

Impacts from coastal development within this species distribution are likely to have been significant. This species is known to have been extirpated from one locality due to the construction of a radio mast (G. Feulner pers. comm. 2019). In addition, grazing by goats could present a threat within specific localities, such as Wadi Siji.

History

Increasing frequency and intensity of development, both commercial and residential, since 1996 mean that it is now listed as Near Threatened rather than Least Concern.

(see Assessment details)

Assessment rationale/justification

This species is considered to be rare within its range and is often grazed to the point of visibly stunted growth. This may pose a significant threat to the species, however the full extent of this is still unclear. Although the species occurs in a National Park, it is important to draw attention to this potentially threatened and rare species. As a result, it is cautiously assessed as Vulnerable (D1) as a result of the small number of mature individuals, which is suspected to be close to or less than 1,000, but no reliable count has been made. It also has a restricted distribution (estimated EOO: 6,378 km2). The species occurs in adjacent parts of Oman and the seed is wind-dispersed, therefore the assessment is revised down by one category to Near Threatened.

This is a perennial or annual succulent that grows up to 35 cm (Western 1992, Jongbloed et al. 2003). It produces purple flowers between February and May, in addition to characteristic pickle-shaped fruit, and grows among rocks, gravel plains, wadis and mountains (Jongbloed et al. 2003, Feulner 2016). When the plant is damaged, it secretes milky sap (latex) which is characteristic of Asciepiadaceae species (Western 1992). The species is considered to be a xerohalophyte i.e. a salt-tolerant desert species (Böer and Saenger 2006).

Threats and conservation measures listed

Threats listed in assessment

This species is may be difficult to identify as the plant is often grazed to the point of a very stunted growth form (Western 1992) and fruits are consumed by people.

History

The situation is not thought to have changed for this species since 1996.

This species occurs within a very restricted range in the UAE: the estimated Extent of Occurrence (EOO) is approximately 200 km2. The area of occupancy (AOO) is likely to be similarly restricted. In addition, it is only found at higher altitudes within this area and is considered to generally be rare, and subpopulations are small, perhaps with 20-30 individuals in a subpopulation. As such, any potential threats to this species could cause it to become threatened within a short space of time. The species is cautiously assessed as Near Threatened based on a presumed restricted population size and habitat availability in order to highlight threats or declines to this species.

Assessment rationale/justification

Within the UAE, this species occurs in the Hajar Mountains from Masafi (Wadi Ham south to the border with Oman, including Wadi Hatta), and also occurs on Jebel Hafeet. some subpopulations may be the result of intentional cultivation for use. The extent of occurrence (EOO) is between 1,500 and 2,000 km2, and the AOO at less than 500 km2. There is no information on population size or trend. The species is assessed as Near Threatened as, whilst the extent of occurrence (EOO) and area of occupancy (AOO) are restricted, and it is suspected that the species occurs in between eight and ten locations, there is no evidence of widespread threats within its distribution range, or of continuing decline. The species would qualify as Vulnerable if a continuing decline in the number of mature individuals, or in habitat area, extent or quality was known or suspected. In addition, the species might potentially qualify as threatened under criterion D, however further information on the population structure of this probably clonal species is required.

Taxon distribution as listed in assessment

Within the UAE, this species occurs along the western slopes of the Hajar Mountains from Shawka, south to the border with Oman (Jongbloed et al. 2003, Feulner 2011). The species also occurs on Jebel Hafeet (Perry 2008) on the northern summit wadi on Jebel Hafeet (at almost 1,000 m asl; G.R. Feulner, in lit. MEW 2010), where it persists (S. Sakkir and G. Brown pers. comm. 2018). According to G.R. Feulner (in lit. MEW 2010), this species ""is consistently present as one or a few clumps/groves in almost every wadi from Shawka south [to the Oman border], normally at places where the wadi broadens for one reason or another and silt accumulates. It is relatively common in the wadis in the greater Juwaif area, about half-way between the Hatta Road and Mahdhah."" The Sharjah Seedbank & Herbarium (SSBH) recorded the species from the Al Dhaid-Masafi road (Thaoban), and found four new clumps of the plant in Al-Bardy and Al-Wishah (in gravelly area east of Dhaid); these clumps are located inside farms, and local people reported that ""...they planted it"" a long time ago (T. Mahmoud pers. comm. 2019). The EOO is estimated at between 1,500 and 2,000 km2, whilst the AOO is less than 500 km2 and is likely to be as little as 300 km2. The species also occurs in adjacent areas of Oman (G.R. Feulner in lit. MEW 2010). Globally, the species is native from the southern Arabian Peninsula to Iran and Pakistan (Board of Trustees, RGB Kew 2018).

This plant species is described as perennial tree with fan-shaped leaves forming clumps several meters across that generally occurs in gravelled areas along low wadi banks (Jongbloed et al. 2003). According to G.R. Feulner (in lit, MEW 2010), the species is normally found at places where wadi broaden and silt accumulates.

Threats and conservation measures listed

Threats listed in assessment

MEW (2010) considered populations fragmented and at threat from development, without giving details. At one site in the Hajar Mountains, quarrying activities had lowered the wadi floor by at least 2 m, with consequential impacts on the ground water level. As a result, one cluster of the palm in the wadi is dying (D. Aplin pers. comm. 2019). The species is generally found in the lower parts of wadis and it is therefore vulnerable to development, e.g. road construction, and other works.

History

The situation for this species in 1996 is thought to be similar to the situation for the species now.

It is described as being a xerohalophyte: a salt-tolerant desert growing species (Ghazanfar and Fisher 1998, Böer and Saenger 2006). This plant has woody stems and can grow up to 1.0 m in height, producing red flowers streaked with yellow between February and April (Jongbloed et al. 2003). Indigofera oblongifolia is also a crop wild relative of indigo, Indigofera tinctoria (Kameswara Rao 2010).

Threats and conservation measures listed

Threats listed in assessment

This species may have been negatively impacted by ongoing development along the east coast of the UAE.

History

There was less coastal development occurring in 1996 compared to now, and so it is deemed that it would have been Least Concern in 1996.

The AOO is a maximum of c. 180 km2 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.

Taxon distribution as listed in assessment

In the UAE, this species is restricted to the Ru'us al Jibal (Jongbloed et al. 2003), where it was first recorded for the UAE at Wadi Beh (Böer and Chaudhary 1999). Feulner (2011) recorded the species from c. 250 m to at least 1,200 m elevation in wadis. Shahid (2017) recorded the species from Wadi Ghalilah (Ra's al-Khaimah). The EOO, based on the map from Jongbloed et al. (2003) and the records from Shahid (2017), is highly restricted, at less than 200 km2. The AOO is a maximum of c. 180 km2 but is likely to be very much less. The global range of this species is circum-Mediterranean, extending to north-east Africa, through much of the Arabian Peninsula, and on to Iran and Iraq (Plants of the World online, Board of Trustees, RBG Kew 2019).

Assessment rationale/justification

This species occurs in a distinct, restricted area within the UAE, with an estimated extent of occurrence (EOO) of 2,322 km2: 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.

Habitat

Habitat details as listed in assessment

This small tree species grows on sand sheets and sand dunes (Böer and Saenger 2006). It can reach heights of 3 m and has fleshy branches with drooping shoots, giving an appearance similar to a weeping willow (Jongbloed et al. 2003). It produces yellow winged fruits and flowers between February and May (Jongbloed et al. 2003).

Threats and conservation measures listed

Threats listed in assessment

Grazing by camels, in addition to ongoing development, threatens this species outside of protected areas.

History

This species would have been of a lower threat category in 1996 due to occupying a larger area. However, its distribution has now declined due to ongoing coastal development.
