The dunes of Lençóis Maranhenses or sheets (lençois) of Maranhão are an important area of environmental preservation. Another important conservation area is the Parnaíba River delta, between the states of Maranhão and Piauí, with its lagoons, desert dunes and deserted beaches or islands, such as the Caju island, which shelters rare birds.
