How much of the Audouin's gull distribution range is protected?

Audouin's gull is a large gull restricted to the Mediterranean and the western coast of Saharan Africa and the Iberian Peninsula. This gull breeds in the Mediterranean sea and it winters on the coast of North and West Africa from Libya west to Morocco and south to Mauritania, Gambia, Senegal and Gabon and there is a small wintering population in the east Mediterranean along the Aegean coast of Turkey.The population has suffered a rapid reduction since around 2010, following the reduction in fisheries discards (after previous unsustainable levels of trawl discards had driven a substantial population increase over the previous three generations) It is classified as vulnerable.
