Data Zone
The site was identified as internationally important for bird conservation in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2013) is shown below.
