Geography

Italy is located in Southern Europe, between latitudes 35° and 47° N, and longitudes 6° and 19° E. To the north, Italy borders France, Switzerland, Austria, and Slovenia, and is roughly delimited by the Alpine watershed, enclosing the Po Valley and the Venetian Plain. To the south, it consists of the entirety of the Italian Peninsula and the two Mediterranean islands of Sicily and Sardinia, in addition to many smaller islands. The sovereign states of San Marino and the Vatican City are enclaves within Italy, while Campione d'Italia is an Italian exclave in Switzerland.

The country's total area is 301,230 square kilometres (116,306 sq mi), of which 294,020 km2 (113,522 sq mi) is land and 7,210 km2 (2,784 sq mi) is water. Including the islands, Italy has a coastline and border of 7,600 kilometres (4,722 miles) on the Adriatic, Ionian, Tyrrhenian seas (740 km (460 mi)), and borders shared with France (488 km (303 mi)), Austria (430 km (267 mi)), Slovenia (232 km (144 mi)) and Switzerland (740 km (460 mi)). San Marino (39 km (24 mi)) and Vatican City (3.2 km (2.0 mi)), both enclaves, account for the remainder.

The Apennine Mountains form the peninsula's backbone and the Alps form most of its northern boundary, where Italy's highest point is located on Monte Bianco (4,810 m or 15,780 ft).The Po, Italy's longest river (652 kilometres or 405 miles), flows from the Alps on the western border with France and crosses the Padan plain on its way to the Adriatic Sea. The five largest lakes are, in order of diminishing size: Garda (367.94 km2 or 142 sq mi), Maggiore (212.51 km2 or 82 sq mi, shared with Switzerland), Como (145.9 km2 or 56 sq mi), Trasimeno (124.29 km2 or 48 sq mi) and Bolsena (113.55 km2 or 44 sq mi).

The country is situated at the meeting point of the Eurasian Plate and the African Plate, leading to considerable seismic and volcanic activity. There are 14 volcanoes in Italy, four of which are active: Etna (the traditional site of Vulcan’s smithy), Stromboli, Vulcano and Vesuvius. Vesuvius is the only active volcano in mainland Europe and is most famous for the destruction of Pompeii and Herculanum. Several islands and hills have been created by volcanic activity, and there is still a large active caldera, the Campi Flegrei north-west of Naples.

Although the country comprises the Italian peninsula and most of the southern Alpine basin, some of Italy's territory extends beyond the Alpine basin and some islands are located outside the Eurasian continental shelf. These territories are the comuni of: Livigno, Sexten, Innichen, Toblach (in part), Chiusaforte, Tarvisio, Graun im Vinschgau (in part), which are all part of the Danube's drainage basin, while the Val di Lei constitutes part of the Rhine's basin and the islands of Lampedusa and Lampione are on the African continental shelf.

Climate

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.

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).

Fauna and flora

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. 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. However, as of 2005, 6,759 species are recorded in the Data bank of Italian vascular flora. 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.
