The site was identified as important in 2005 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
Garganey Spatula querquedula	LC	breeding	1998	400-600 breeding pairs	B2
Corncrake Crex crex	LC	breeding	1998	200-300 breeding pairs	A1
Spotted Crake Porzana porzana	LC	breeding	1998	250-400 breeding pairs	B3
Great Snipe Gallinago media	NT	breeding	2004	20 breeding pairs	A1
Little Gull Hydrocoloeus minutus	LC	breeding	1998	20 breeding pairs	B2
Black Tern Chlidonias niger	LC	breeding	1998	80-200 breeding pairs	B2
Greater Spotted Eagle Clanga clanga	VU	breeding	2003	2-3 breeding pairs	A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2005) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2005. The most recent assessment (2018) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Garganey Spatula querquedula	200	220	breeding pairs	100	favourable
Great Snipe Gallinago media	20	15	males	75	near favourable
Black Tern Chlidonias niger	50	70	breeding pairs	100	favourable
Greater Spotted Eagle Clanga clanga	2	2	breeding pairs	100	favourable

Pressure (threats to the trigger species and/or their habitats)
