The site was identified as important in 2000 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
Whooper Swan Cygnus cygnus	LC	passage	1997	250-350 individuals	B1i, C2
Eurasian Bittern Botaurus stellaris	LC	breeding	1997	11 breeding pairs	B2, C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Smew Mergellus albellus	100	50	individuals	50	unfavourable
Common Pochard Aythya ferina	400	100	individuals	25	very unfavourable
Gallinula chloropus	7	2	breeding pairs	29	very unfavourable
Western Marsh-harrier Circus aeruginosus	5	3	breeding pairs	60	unfavourable
Acrocephalus arundinaceus	12	20	breeding pairs	100	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Transportation and service corridors	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	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
Most of site (50-90%) covered (including the most critical parts for important bird species)	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	low
