The site was identified as important in 2007 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
White-headed Duck Oxyura leucocephala	EN	breeding	2004	1-10 breeding pairs	A1, B2
Ferruginous Duck Aythya nyroca	NT	breeding	2004	15-25 breeding pairs	A1, B2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2006) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
White-headed Duck Oxyura leucocephala	2	1	breeding pairs	50	unfavourable
Common Shelduck Tadorna tadorna	5	3	breeding pairs	60	unfavourable
Ruddy Shelduck Tadorna ferruginea	15	8	breeding pairs	54	unfavourable
Ferruginous Duck Aythya nyroca	15	12	breeding pairs	80	near favourable
Glossy Ibis Plegadis falcinellus	200	44	individuals	22	very unfavourable
Pygmy Cormorant Microcarbo pygmaeus	11	11	individuals	100	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Agricultural expansion and intensification	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low

Habitat1	Habitat detail	% of IBA
Desert	Semidesert	16
Wetlands (inland)	Standing brackish and salt water	major (>10)

1. IUCN Habitat classification.

Land use	% of IBA
hunting	100
agriculture	20
