The site was identified as important in 2004 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
White-headed Duck Oxyura leucocephala	EN	winter	1995-1996	20-34 individuals	A1
Eurasian Spoonbill Platalea leucorodia	LC	breeding	1989-1995	200 breeding pairs	A4i, B1i, B2
Black-crowned Night Heron Nycticorax nycticorax	LC	breeding	-	1,500 breeding pairs	A4i, B1i, B2
Squacco Heron Ardeola ralloides	LC	breeding	1989-1996	100 breeding pairs	B2
Dalmatian Pelican Pelecanus crispus	NT	winter	1992-1996	52-117 individuals	A1, A4i, B1i
Dalmatian Pelican Pelecanus crispus	NT	breeding	-	35-40 breeding pairs	A1, A4i, B1i, B2
Great White Pelican Pelecanus onocrotalus	LC	passage	-	1,500-5,000 individuals	A4i, B1i
Pygmy Cormorant Microcarbo pygmaeus	LC	breeding	1989-1996	150 breeding pairs	A1, B1i, B3
Pygmy Cormorant Microcarbo pygmaeus	LC	winter	-	58-315 individuals	A1
Great Cormorant Phalacrocorax carbo	LC	breeding	-	2,650-3,000 breeding pairs	A4i, B1i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2016) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	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
Whole area of site (>90%) covered by appropriate conservation designation	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	high

Year	Protected Area	Designation	% overlap with IBA
1959	Kuscenneti	National Park	78
1981	Kusgolu	SIT (Law on Protection of Cultural and Natural Assets No. 2863)	<1
1994	Lake Kus	Ramsar Site, Wetland of International Importance	73

Habitat1	Habitat detail	% of IBA
Wetlands (inland)	Standing freshwater, Water fringe vegetation	95
Forest	Alluvial and very wet forest	5

1. IUCN Habitat classification.

Land use	% of IBA
water management	80
urban/industrial/transport	80
agriculture	10
fisheries/aquaculture	10
