This is the only natural area protected in this province. Also it is known as the Gran Florida del Duero (the Great Florida of the Douro) .[2] Is located in an area of moorland and sedimented banks. Therefore this is an area of nesting and migratory water birds. The Duero is surrounded by forests of Ribera and constitutes a very interesting swamp ecosystem. It is an area of great plains and absence of high elevations HistoryIn the 1940s a dam was constructed across the Douro River as part of a hydroelectric plant. Upstream, in the municipal district of Castronuño, was created the reservoir of San Jose, which was what brought about the formation of this reserve, which constitutes a unique ecosystem with biotic elements and landscape. Many sediments were flooded and changed the riverbank to fertile fields, which were gradually colonized by large masses of the reedbed, maintained by the constant level of the reservoir. The greater growing mass of the reedbed attracted more birds attracted to the habitat of the wetlands. It is a semi-natural wetland. The nature reserve was considered a Special Protection Area for Birds in 1992 and Strict Nature Reserve in 2002. {{commons category|Reserva Natural de las Riberas de Castronuño-Vega del Duero}}References1. ^BirdLife International (2014) Important Bird Areas factsheet: Castronuño-Zamora.
