Three mountain ranges are present: Pollino, La Sila and Aspromonte, each with its own flora and fauna. The Pollino Mountains in the north of the region are rugged and form a natural barrier separating Calabria from the rest of Italy. Parts of the area are heavily wooded, while others are vast, wind-swept plateaus with little vegetation. These mountains are home to a rare Bosnian Pine variety and are included in the Pollino National Park, which is the largest national park in Italy, covering 1,925.65 square kilometres.
