The site was identified as important in 2016 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
Northern Shoveler Spatula clypeata	LC	non-breeding	2011-2015	948-1,378 individuals	B1i, C3
Spotted Crake Porzana porzana	LC	breeding	2011-2015	17-32 breeding pairs	B3, C6
Baillon's Crake Zapornia pusilla	LC	breeding	2011-2015	2 breeding pairs	C6
Ruff Calidris pugnax	LC	breeding	2011-2015	2-3 breeding pairs	C6
A4iii Species group - waterbirds	n/a	non-breeding	2011-2015	27,906-40,186 individuals	A4iii, C4

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2016) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2017) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Northern Shoveler Spatula clypeata	120	948	individuals	100	favourable
