Clear waters, uncontaminated nature, strips of land rich in history and archaeological remains, active salt marshes, shallow waters, which can also be traveled on foot in some places, characterize the Stagnone Islands Oriented Nature Reserve, one of the first to be established in Sicily (1984 ); it protects the Stagnone lagoon, a body of water, bordered by the open sea by the Isola Grande, with three small islands in its interior, Mozia, Santa Maria and Schola. At the edges of the canals of the salt pans there are halophytic plants, including suaeda maritima, salicornia, salsola soda, limonium, inula, limoniastrum. Since July, the Stagnone has hosted autumn migratory birds: curlews and glossy ibis; with the cold the ducks arrive, with the marsh harrier waiting for them in ambush, pochards, teals, coots, mallards, pintails and garganeys. Superb and haughty herons look for food among the tanks of the salt pans.
