Assessment rationale/justification
This species occurs in protected areas and is also able to persist in disturbed areas. It is salt-tolerant and seems to persist in unfavourable conditions, despite being described as rare. It has a restricted distribution with an estimated extent of occurrence (EOO) of 887 km<sup>2</sup>. In addition, it is thought to be experiencing an ongoing decline of extent and quality of habitat due to coastal development. The number of threat-based locations within which this species occurs is currently unclear. Therefore, it is assessed as Near Threatened.

Habitat details as listed in assessment
This species is a perennial shrub which is found growing in sand and gravel plains (Mahmoud et al. 2018), in addition to disturbed areas such as abandoned fields and roadsides (Jongbloed et al. 2003, MEW 2010). 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.
