Marshes, Swamps and Lagoons
In the lowlands, as the waters slow their flow towards the sea, many marshes and swamps are formed, along with the many associated lagoons. These areas are very important for conservation because of the wide variety of life that is dependent on them, from frogs and reptiles to fish and all the birds that feed on them. In these marshes, one can find the endemic and endangered Paraná Antwren (locally known as the bicudinho-do-brejo, Formicivora acutirostris). These habitats also provide important ecosystem services, such as water purification and reservoirs of life.
