Current view: Data table and detailed info

IBA Justification

The site was identified as internationally important for bird conservation in 2000 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	resident (1996)	10–30 pairs	C6
Whooper Swan Cygnus cygnus	LC	passage (1996)	100–200 birds	C2
Bean Goose Anser fabalis	LC	passage (1996)	300–800 birds	B1i, C3
Osprey Pandion haliaetus	LC	breeding (1996)	3–10 pairs	C6

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2018) is shown below.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2018	good	high	very low
Whole site assessed?	State assessed by	Accuracy of information
yes	habitat	medium

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	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	few individuals/small area (<10%)	no or slight decline (<1% over 3 generations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	Not assessed	Not assessed	very low
