The site was identified as important in 2011 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
Little Bustard Tetrax tetrax	NT	winter	2006	min 450 individuals	A1, C1
Little Bustard Tetrax tetrax	NT	resident	2009	present	A1, C1
Great Bustard Otis tarda	EN	resident	2011	170-190 individuals	A1, C1, C6
Black-crowned Night Heron Nycticorax nycticorax	LC	breeding	2007	min 173 breeding pairs	C2, C6
Black-winged Stilt Himantopus himantopus	LC	breeding	2007	min 84 breeding pairs	C6
Western Marsh-harrier Circus aeruginosus	LC	winter	2007	min 42 individuals	C6
Western Marsh-harrier Circus aeruginosus	LC	resident	2007	min 23 breeding pairs	C6
Red-billed Chough Pyrrhocorax pyrrhocorax	LC	resident	2003	min 25 breeding pairs	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2011) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2007) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	moderate (70-90%)	moderate (70-90%)	unfavourable
Artificial/Terrestrial	good (> 90%)	good (> 90%)	favourable
Shrubland	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Pollution	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Residential and commercial development	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Transportation and service corridors	likely in short term (within 4 years)	majority/most of area/population (50-90%)	very rapid to severe deterioration	high
Energy production and mining	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	whole area/population (>90%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	No management planning has taken place	Very little or no conservation action taking place	low
