The site was identified as important in 2003 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
Green Peafowl Pavo muticus	EN	resident	2001	common	A1
Sarus Crane Grus antigone	VU	resident	2001	common	A1
Greater Adjutant Leptoptilos dubius	NT	non-breeding	2001	uncommon	A1
Lesser Adjutant Leptoptilos javanicus	NT	resident	2001	common	A1
White-shouldered Ibis Pseudibis davisoni	CR	resident	2001	rare	A1
Giant Ibis Thaumatibis gigantea	CR	resident	2001	rare	A1, A4i
Greater Spotted Eagle Clanga clanga	VU	winter	2001	uncommon	A1

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 (2008) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Shrubland	moderate (70-90%)	moderate (70-90%)	unfavourable
Artificial/Terrestrial	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Transportation and service corridors	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Residential and commercial development	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Biological resource use	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
Most of site (50-90%) covered (including the most critical parts for important bird species)	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
