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 IBA criteria.

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

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Stock Dove Columba oenas	LC	breeding (1992)	101–500 breeding pairs	B3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the key species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Stock Dove Columba oenas	100 / 100 (breeding pairs)	100	favourable

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happen­ing now	most of popul­ation/area (50–90%)	no deteri­oration (<1% over 3 gener­ations)	low
Pollution	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
Most of site (50–90%) covered (including the most critical parts for important bird species)	A manage­ment plan exists, but it is out of date or not compre­hensive	Some limited conservation initiatives are in place	low

Habitat	% of IBA	Habitat detail
Forest	68	Broadleaved deciduous woodland; Native coniferous woodland; Mixed woodland
Artificial/Terrestrial	20	Arable land
Grassland	12	Alpine, subalpine and boreal grassland

Land use	% of IBA
nature conservation and research	50
unknown	30
agriculture	20
