Current view: Data table and detailed info

IBA Justification

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
Common Pochard Aythya ferina	VU	winter	1998	9,000-14,000 individuals	A4i, B1i
Tufted Duck Aythya fuligula	LC	winter	1998	17,000-25,000 individuals	A4i, B1i
A4iii Species group - waterbirds	n/a	winter	1998	20,000-49,999 individuals	A4iii

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

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 (2011) is shown below.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2011	not assessed	high	low
Whole site assessed?	State assessed by	Accuracy of information
yes	unset	medium

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	whole area/population (>90%)	slow but significant deterioration	high
Residential and commercial development	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low
Human intrusions and disturbance	happening now	whole area/population (>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
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	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	No management planning has taken place	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low
