1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2019) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Black Tern Chlidonias niger	3,900	5	mature individuals	1	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	likely in short term (within 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	past (and unlikely to return) and no longer limiting	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
Whole area of site (>90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	medium
