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
Black Stork Ciconia nigra	LC	breeding	2000	30-50 breeding pairs	B2
Short-toed Snake-eagle Circaetus gallicus	LC	breeding	2000	10-15 breeding pairs	B2
Lesser Spotted Eagle Clanga pomarina	LC	breeding	2004	30 breeding pairs	B2
Greater Spotted Eagle Clanga clanga	VU	breeding	2000	3-5 breeding pairs	A1
Montagu's Harrier Circus pygargus	LC	breeding	2000	40-60 breeding pairs	B3

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 (2017) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	likely in short term (within 4 years)	whole area/population (>90%)	very rapid to severe deterioration	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed
