1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2003) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2003. The most recent assessment (2009) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Sarus Crane Grus antigone	87	87	individuals	100	favourable
Lesser Adjutant Leptoptilos javanicus	338	338	individuals	100	favourable
Giant Ibis Thaumatibis gigantea	69	14	individuals	21	very unfavourable
Red-headed Vulture Sarcogyps calvus	19	19	individuals	100	favourable
White-rumped Vulture Gyps bengalensis	62	43	individuals	70	near favourable
Slender-billed Vulture Gyps tenuirostris	11	11	individuals	100	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Residential and commercial development	happening now	small area/few individuals (<10%)	slow but significant 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	No management plan exists but the management planning process has begun	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium

Year	Protected Area	Designation	% overlap with IBA
