Current view: Data table and detailed info

IBA Justification

The site was identified as important in 2008 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
Whooper Swan Cygnus cygnus	LC	winter	2003-2006	66-634 individuals	B1i
Mallard Anas platyrhynchos	LC	winter	2003-2006	68,240-80,000 individuals	A4i, B1i
Glossy Ibis Plegadis falcinellus	LC	breeding	2004-2006	1,050 breeding pairs	A4i, B1i, B2
Black-crowned Night Heron Nycticorax nycticorax	LC	breeding	2006	200 breeding pairs	B2
Squacco Heron Ardeola ralloides	LC	breeding	2004-2006	50-55 breeding pairs	B2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2008) may differ.

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2006) is shown below.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2006	near favourable	high	negligible
Whole site assessed?	State assessed by	Accuracy of information
no	habitat	medium

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	moderate (70-90%)	good (> 90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
