The site was identified as important in 2019 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2019) may differ.

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 area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	no or imperceptible 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)	No management planning has taken place	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
1978	Reserve ornithologique de Kalissaye	Bird Reserve	100
2017	Kalissaye	Ramsar Site, Wetland of International Importance	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.
