The site was identified as important in 2019 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
Black-headed Duck Heteronetta atricapilla	LC	resident	2015-2019	195-518 individuals	A4, B3a
Lake Duck Oxyura vittata	LC	unknown	2008	672 individuals	A4, B3a
Southern Silvery Grebe Podiceps occipitalis	LC	non-breeding	2015-2019	400-3,000 individuals	A4, B3a
Black Rail Laterallus jamaicensis	EN	resident	2015-2019	1-10 individuals	B1a

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2019) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2017) is shown below.

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

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
