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 (2001) 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%)	moderate to rapid deterioration	high
Pollution	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	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being comprehensively and effectively implemented	high

Year	Protected Area	Designation	% overlap with IBA
1978	Banc d'Arguin	National Park	100
1982	Banc d’Arguin	Ramsar Site, Wetland of International Importance	100
1989	Banc d'Arguin National Park	World Heritage Site (natural or mixed)	100
