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 (2017) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
White-faced Whistling-duck Dendrocygna viduata	58,613	131,000	mature individuals	100	favourable
Garganey Spatula querquedula	147,563	114,000	individuals	78	near favourable
Ruff Calidris pugnax	108,381	98,000	individuals	91	favourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	good (> 90%)	good (> 90%)	favourable
Artificial/Terrestrial	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
