The site was identified as important in 2011 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
Red-crested Pochard Netta rufina	LC	non-breeding	2009	400-800 individuals	B1i, C3
Red-crested Pochard Netta rufina	LC	passage	2010	min 600 individuals	B1i, C3
Gadwall Mareca strepera	LC	resident	2010	min 50 breeding pairs	B2
Gadwall Mareca strepera	LC	winter	2010	max 1,000 individuals	B1i, C3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2011) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2007) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Gadwall Mareca strepera	110	50	breeding pairs	46	unfavourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Residential and commercial development	likely in long term (beyond 4 years)	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
Human intrusions and disturbance	happening now	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
Some of site covered (10-49%)	No management planning has taken place	Not assessed	negligible
