Fauna and flora

Main articles: Fauna of Italy and Flora of Italy

Italy has the highest level of faunal biodiversity in Europe, with over 57,000 species recorded, representing more than a third of all European fauna.^[92] The Italian peninsula is in the centre of the Mediterranean Sea, forming a corridor between central Europe and North Africa, and has 8,000 km of coastline. Italy also receives species from the Balkans, Eurasia, the Middle East. Italy's varied geological structure, including the Alps and the Apennines, Central Italian woodlands, and Southern Italian Garigue and Maquis shrubland, also contribute to high climate and habitat diversity.
The flora was traditionally estimated to comprise about 5,500 vascular plant species.^[93] However, as of 2005, 6,759 species are recorded in the Data bank of Italian vascular flora.^[94] Geobotanically, the Italian flora is shared between the Circumboreal Region and Mediterranean Region. Italy is a signatory to the Berne Convention on the Conservation of European Wildlife and Natural Habitats and the Habitats Directive both affording protection to the Italian fauna and flora.

Climate

Southern Italy has a Mediterranean climate

Main article: Climate of Italy

Thanks to the great longitudinal extension of the peninsula and the mostly mountainous internal conformation, the climate of Italy is highly diverse. In most of the inland northern and central regions, the climate ranges from humid subtropical to humid continental and oceanic. In particular, the climate of the Po valley geographical region is mostly continental, with harsh winters and hot summers.^[95][96]
The coastal areas of Liguria, Tuscany and most of the South generally fit the Mediterranean climate stereotype (Köppen climate classification Csa). Conditions on peninsular coastal areas can be very different from the interior's higher ground and valleys, particularly during the winter months when the higher altitudes tend to be cold, wet, and often snowy. The coastal regions have mild winters and warm and generally dry summers, although lowland valleys can be quite hot in summer. Average winter temperatures vary from 0 °C (32 °F) on the Alps to 12 °C (54 °F) in Sicily, like so the average summer temperatures range from 20 °C (68 °F) to over 25 °C (77 °F).^[97]
