Monteferrato Protected Area of Local Interest lies within the hilly-mountain system delimiting the Florence-Prato-Pistoia plain in the north. The area was named after the mountain complex of Monteferrato, a pre-apennine spur formed by three peaks (Piccioli, Mezzano, and Chiesino or Poggio Ferrato) reaching a maximum height of 420m above sea level and characterized by peculiar geological features given by the abundance of ophiolitic rocks, which led to the formation of a unique biotope, completely different from the surrounding natural environments from an ecological point of view.
