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 IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Black Kite Milvus migrans	LC	breeding (2004–2009)	5–7 breeding 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 (2009) is shown below.

State (condition of the key species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Milvus migrans	7 / 7 (breeding pairs)	100	favourable

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

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Biological resource use	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Human intrusions and disturbance	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Pollution	happen­ing now	whole popul­ation/area (>90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Invasive and other problematic species and genes	happen­ing now	whole popul­ation/area (>90%)	moderate deteri­oration (10–30% in 3 gener­ations)	very high
Natural system modifications	happen­ing now	most of popul­ation/area (50–90%)	rapid deteri­oration (>30% over 3 gener­ations)	very high
Climate change and severe weather	happen­ing now	most of popul­ation/area (50–90%)	moderate deteri­oration (10–30% in 3 gener­ations)	high
Energy production and mining	likely in short term (within 4 years)	most of popul­ation/area (50–90%)	rapid deteri­oration (>30% over 3 gener­ations)	high
Transportation and service corridors	happen­ing now	some of popul­ation/area (10–49%)	slow deteri­oration (1–10% over 3 gener­ations)	medium
No known threats	happen­ing now	few individ­uals/small area (<10%)	no deteri­oration (<1% over 3 gener­ations)	low

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Some of site covered (10–49%)	No manage­ment planning has taken place	Very little or no conservation action taking place	very low
