The Natural Reserve of the Marshes of Castro Marim and Vila Real de Santo António (PTZPE0018 – Castro Marim Marshes) was created in 1975 with the objective of maintaining the natural values of the estuary of the Guadiana River. The Natural Reserve presents marshes, salt flats and pastures for cattle, migratory birds also nest and numerous species of fish and mollusks live there.
The salt flats are particularly representative and become the habitat to a large part of the waterfowl populations that motivated the creation of this SPA. Some of these species are: the Kentish Plover (Charadrius alexandrinus), the Pied Avocet (Recurvirostra avosetta), the Black-winged Stilt (Himantopus himantopus) and the Little Tern (Sterna albifrons).
The Castro Marim salt flats are made up of small plots where the salt and the flower of salt are exploited in a traditional way.
Jorge Filipe Raiado Pereira, on behalf of Insonso SalMarim Lda, owner of the “Meias” salt flats, signed a letter of support for the LIFE-Salinas Project. For this reason, the Castro Marim salt flats will be a pioneer action for the development of the E3 action of the Project: “Design and implementation of a quality and environmental protection certificate for the salt of the Natura 2000 salt flats”.
Sal Marim has years of experience in the exploitation of the Castro Marim marshes, especially in the extraction of salt flower, and has distinguished itself for its marketing and innovation strategy which integrates the component of maintaining biodiversity and landscape for the sale of its products.
