The Tagus Estuary Nature Reserve (RNET) is located in an area of high natural richness and diversity. Covering approximately 14,415 hectares, it is integrated into the largest wetland area in Portugal – the Tagus Estuary, including estuarine waters, sandbanks, salt pans, agricultural land, and cork oak forests. The connectivity of these habitats ensures the presence of a great diversity of living beings, such as mollusks, crustaceans, and small amphibians. It is also a nursery for various species of marine fish and a very important ecosystem for migratory fish. The estuary is also of great importance to aquatic birds, being one of the places with the most wintering birds in Europe.
