Réserve Naturelle de la Baie de l'Étoile (Baie de l'Étoile Nature Reserve)

Coastal/marine nature reserve covering ~12 km2 in the Baie du Lévrier, about 14 km north of Nouadhibou. Officially designated a Nature Reserve by the Mauritanian state in July 2024. It shelters seagrass meadows, maerl beds, sandbanks, rocky islets and over 470 marine and bird species. Unregulated fishing ('pêche non encadrée') is identified as a threat the reserve aims to control; recreational spearfishing is not documented as permitted within the reserve.
