The site was identified as internationally important for bird conservation in 2009 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 List	Season (year/s of estimate)	Size	IBA criteria
Hazel Grouse Tetrastes bonasia	LC	breeding (1990–2009)	2–5 pairs	C6
Black Stork Ciconia nigra	LC	breeding (2000–2009)	1–2 pairs	C6
European Honey-buzzard Pernis apivorus	LC	breeding (2000–2009)	3–5 pairs	C6
Red Kite Milvus milvus	LC	breeding (2003–2009)	2–6 pairs	C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2009) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Hazel Grouse Tetrastes bonasia	5 / 15 (pairs)	34	very poor
Black Stork Ciconia nigra	1 / 1 (pairs)	100	good
Red Kite Milvus milvus	3 / 1 (pairs)	100	good

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (>90%)	good (>90%)	good
Wetlands (inland)	good (>90%)	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Natural system modifications	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	No management plan exists, but the management planning process has begun	Some limited conservation initiatives are in place	low
