The Cecina river
bears the name of an Etruscan family
The wide riverbed of the Cecina river with its changing vegetation and gravel terraces on the riverside are a characteristic element of the landscape.
The important fluvial ecosystems are of particular naturalist interest, and present differing habitats such as river terraces, poplars and willows, while at the ‘Masso delle Fanciulle’ (Berignone Nature Reserve) the holophytic undergrowth houses numerous endemic species. The agricultural ecosystem of the river basin is a precious hunting ground for the short-toed snake eagles that nest in the surrounding woodlands. Amongst the other species of interesting birds is the lesser grey shrike, part of the traditional landscape, and the rare Eurasian stone-curlew, while in some parts of the river the European pond turtle can be found.
