The site was identified as internationally important for bird conservation in 2019 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 List	Season (year/s of estimate)	Size	IBA criteria
Great White Pelican Pelecanus onocrotalus	LC	non-breeding (2014–2017)	376–1,008 birds	B3a
Eurasian Oystercatcher Haematopus ostralegus	NT	winter (2014–2017)	62–110 birds	B1a
Eurasian Curlew Numenius arquata	NT	winter (2014–2017)	31–56 birds	B1a
Bar-tailed Godwit Limosa lapponica	NT	winter (2014–2017)	112–216 birds	B1a
Black-tailed Godwit Limosa limosa	NT	winter (2014–2017)	90–130 birds	B1a
Red Knot Calidris canutus	NT	winter (2014–2017)	50 birds	B1a
Curlew Sandpiper Calidris ferruginea	VU	winter (2014–2017)	190–390 birds	B1a
Slender-billed Gull Larus genei	LC	non-breeding (2014–2017)	306–513 birds	B3a
Grey-headed Gull Larus cirrocephalus	LC	non-breeding (2014–2017)	914–2,565 birds	B3a
Little Tern Sternula albifrons	LC	winter (2014–2017)	193–349 birds	B3a

Caspian Tern Hydroprogne caspia	LC	winter (2014–2017)	1,162–2,280 birds	B3a

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2017) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (50–90%) covered (including the most critical parts for important bird species)	No management planning has taken place	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
1978	Reserve ornithologique de Kalissaye	Bird Reserve (IV)	100
2017	Kalissaye	Ramsar Site, Wetland of International Importance (V)	39

Since its designation as a Reserve in 1978, ROK is managed by the Direction National des Parcs (DPN). The islands inside the sreserve are occupied by families who depend their entire life on the resources of the reserve.
