Assessment rationale/justification
This species has a small non-breeding population in the UAE, which qualifies it for listing as Endangered. The population has increased within the country since 1996 but the trend is now thought to be stable.Conditions outside of the UAE are considered unlikely to deteriorate, so there is a potentially very high rescue effect from individuals outside of the country. Therefore, the species is downlisted by two categories to Near Threatened at the national level.

Threats listed in assessment
The most relevant threats within UAE are changes in coastal land-use and the possibility of oil pollution, but the severity of these threats towards this species is unknown.Individuals of this species that visit UAE are also threatened by a range of threats that operate outside of the country. Globally, the species is threatened by wetland habitat degradation and loss (Marchant and Higgins 1990, del Hoyo et al. 1992) for example through drainage, grazing, clearing, burning, increased salinity, groundwater extraction and invasion by exotic plants (Marchant and Higgins 1990). The species previously suffered from intense persecution for the plume trade (this is no longer a threat) (del Hoyo et al. 1992). Climate change is a potential future threat.

History
In 1996, the species was less common, however with a population size that still exceeds 50 mature individuals, found in natural lagoons rather than in anthropogenic habitats. The species qualified as Endangered, downlisted by two categories to Near Threatened based on the significant global rescue effect.
