The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Great Crested Grebe Podiceps cristatus	LC	winter	1998	3,000-4,000 individuals	A4i, B1i
Great Cormorant Phalacrocorax carbo	LC	winter	1998	1,600-3,900 individuals	A4i, B1i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

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.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Residential and commercial development	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Energy production and mining	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	no or imperceptible deterioration	low
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Pollution	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Climate change and severe weather	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
