The species is an important legume species for indigenous populations (it is used to feed animals, such as goats, sheep and camels, to produce high quality honey, for charcoal, as herbal medicine etc.), it is therefore important to ensure that this species is not over-exploited in the future leading to a population decline and to a threatened category. At present, the estimated EOO for this species is 19,222 km² and it is experiencing a decline in habitat extent and quality due to over-grazing and development. However, it is anticipated to occur at more than ten locations, meaning it is assessed as Near Threatened.

In the UAE, the species is known from three records from the Ru'us al-Jibal. There is no information available on population size and trend, but the species is assumed to be impacted by climate change. The area of occupancy (AOO) is inferred to be restricted, certainly very much less than 500 km², but it is not known if the species is severely fragmented. The number of locations is restricted, defined by climate change, based on the currently known localities. The species is assessed as Near Threatened as a precaution, on the basis of the restricted EOO and AOO, and further research is required. Although the species occurs in adjacent parts of these mountains in Oman, there is no rescue effect applied.

Within the UAE, this species is recorded from two desert limestone outcrops, Jebel Faya and Qarn Nazwa. No records from other parts of the UAE have been found and, although the extent of occurrence (EOO) and area of occupancy (AOO) are restricted, it appears that the majority of its range occurs within protected areas. However, Qarn Naswa is subject to grazing impacts from camels and goats, and the species is assessed as Near Threatened (B1a+2a) as a result of its restricted extent of occurrence and area of occupancy, but without evidence of continuing decline.

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.

The extent of occurrence (EOO) of this species is estimated to be less than 10,500-15,000 km² and, although it is widely scattered throughout the UAE, the number of locations is likely to be close to ten. Crotalaria persica is known to have been lost from some areas and is therefore inferred to be declining. Development, including along the coastline, is thought to pose a threat to this species, in addition to grazing by goats. Therefore, it is assessed as Near Threatened under criterion B1.

Bienertia cycloptera occurs from the extreme west of the Arabian Gulf coast, almost to the most northern point of this coastline. Its estimated EOO is 28,675 km² and it is considered to be severely fragmented due to the widely scattered localities in which it occurs. Within its range, it is threatened by development of coastal regions which is causing a continuing decline in the extent and quality of available habitat for this species. Therefore, it is currently assessed as Near Threatened.

In the UAE, the species is recorded from the Ru'us al-Jibal from c.1,100 to c. 1,800 m elevation (Feulner 2011). This species occurs within a restricted range in the UAE: the estimated extent of occurrence (EOO) is approximately 546 km². The area of occupancy (AOO) is likely to be similarly restricted. In addition, it is only found at high altitudes within this area and is considered to generally be rare. This species' habitat is experiencing ongoing decline due to development and grazing, however, the number of threat-based locations is unclear. Therefore, it is assessed as Near Threatened as a precaution, based on its restricted distribution and habitat availability in order to highlight threats or declines to this species. No regional adjustment is made to the assessment.

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 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.

This subspecies is listed as Near Threatened for the UAE. It has a very limited distribution within the United Arab Emirates on gravel plains bordering the Hajar Mountains on the west from 100 m to 300 m asl. The area of occupancy (AOO) is just 24 km², and the extent of occurrence (EOO) is 195 km². There are no current major threats to the species, however, one known locality is subject to intensive recreational use, and another area faces significant potential impacts from gravel extraction. The species has restricted AOO and EOO, and occurs in fewer than ten locations, however at present, no continuing decline is known. It qualifies as NT under Criterion B (B1 and B2). This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations from Oman is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012). Further monitoring and research are required, and the species should be reassessed if new data become available.
