The site was identified as internationally important for bird conservation in 2010 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
Black Stork Ciconia nigra	LC	breeding (1994–1995)	10–15 pairs	C6
Osprey Pandion haliaetus	LC	breeding (2004–2009)	1–2 pairs	C6
Middle Spotted Woodpecker Leiopicus medius	LC	breeding (1994–1995)	150–200 pairs	C6
White-backed Woodpecker Dendrocopos leucotos	LC	breeding (1996–1997)	30–40 pairs	C6

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

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Osprey Pandion haliaetus	1 / 1 (pairs)	100	not assessed
Lesser Spotted Eagle Clanga pomarina	21 / 18 (pairs)	100	not assessed
Dendrocopos leucotos	20 / 20 (pairs)	100	not assessed

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	moderate (70–90%)	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	very 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
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
No known threats	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Residential and commercial development	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Climate change and severe weather	past (and unlikely to return) and no longer limiting	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
