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
Greylag Goose Anser anser	LC	passage	1997	1,000-10,000 individuals	A4i, B1i
Lesser White-fronted Goose Anser erythropus	VU	passage	1997	500-1,000 individuals	A1, A4i, B1i
Great White Egret Ardea alba	LC	passage	1997	70-300 individuals	A4i, B1i
Cinereous Vulture Aegypius monachus	NT	winter	1996	25-30 individuals	A1
Greater Spotted Eagle Clanga clanga	VU	passage	1997	30-100 individuals	A1
Eastern Imperial Eagle Aquila heliaca	VU	passage	1993-1997	25-50 individuals	A1

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
Lesser White-fronted Goose Anser erythropus	1,000	100	individuals	10	very unfavourable
Cinereous Vulture Aegypius monachus	30	0	individuals	0	very unfavourable
Greater Spotted Eagle Clanga clanga	30	20	individuals	67	unfavourable
Eastern Imperial Eagle Aquila heliaca	2	0	breeding pairs	0	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Residential and commercial development	happening now	whole area/population (>90%)	slow but significant deterioration	high
Natural system modifications	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

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10%)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low

Habitat1	Habitat detail	% of IBA
Forest	Broadleaved deciduous woodland	50
Artificial/Terrestrial	Arable land, Perennial crops, orchards and groves, Urban parks and gardens, Other urban and industrial areas	45
Wetlands (inland)	Rivers and streams	4

1. IUCN Habitat classification.

Land use	% of IBA
forestry	50
agriculture	40
urban/industrial/transport	10
