Bulgaria is a country situated in Southeast Europe that occupies the eastern quarter of the Balkan peninsula, being the largest country within its geographic boundaries. It borders Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. The northern border with Romania follows the river Danube until the city of Silistra. The land area of Bulgaria is 110,994 square kilometres (42,855 sq mi), slightly larger than that of Cuba, Iceland or the U.S. state of Tennessee. Considering its relatively compact territorial size and shape, Bulgaria has a great variety of topographical features. Even within small parts of the country, the land may be divided into plains, plateaus, hills, mountains, basins, gorges, and deep river valleys. The geographic center of Bulgaria is located in Uzana.
Vitosha, the ancient Scomius or Scombrus, is a mountain massif, on the outskirts of Sofia, the capital of Bulgaria. Vitosha is one of the symbols of Sofia and the closest site for hiking, alpinism and skiing. Convenient bus lines and rope ways render the mountain easily accessible. Vitosha has the outlines of an enormous dome. The territory of the mountain includes Vitosha nature park that encompasses the best known and most frequently visited parts. The foothills of Vitosha shelter resort quarters of Sofia; Knyazhevo quarter has mineral springs. Vitosha is the oldest nature park in the Balkans. The mountain emerged as a result of volcanic activity and has been subsequently shaped by the slow folding of the granite rock layers and a series of gradual uplifts of the area. It appears dome shaped at first sight, but the mountain, 19 km long by 17 km wide, actually consists of concentric denudational plateaus rising in tiers one above the other. Vitosha is separated into four main parts whose main ridges gather at a crown known as Cherni Vrah. This is the highest point of the mountain at 2290 m and is one of 12 peaks of Vitosha over 2000 m in height. It is the highest massif of Srednogorie mountain chain system, together with Sredna gora, Plana (mountain), Lyulin Mountain, Greben (mountain), Viskyar Mountain, etc. They all are a result of the folding of the earth layers through the Mesozoic, causing also magma sheet-like intrusion that has been injected between layers of sedimentary rock. The laccolithic domed form of Vitosha is a typical example.

The Euxine–Colchic deciduous forests is a temperate broadleaf and mixed forests ecoregion located along the southern shore of the Black Sea. The ecoregion extends along the thin coastal strip from the southeastern corner of Bulgaria in the west, across the northern coast of Turkey, to Georgia in the east, where it wraps around the eastern end of the Black Sea.
The Balkan mixed forests are a terrestrial ecoregion of southeastern Europe according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm.
The South Apennine mixed montane forests is an ecoregion in the southern Apennine Mountains of southern Italy and Sicily. It has a Mediterranean climate, and is in the Mediterranean forests, woodlands, and scrub biome.
The Dinaric Mountains mixed forests are a terrestrial ecoregion of the temperate broadleaf and mixed forests biome in Southeastern Europe, according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It also is in the Palearctic realm.
The Apennine deciduous montane forests are a temperate broadleaf and mixed forests ecoregion in the Apennine Mountains of Italy. The development of these forests is ensured by the high rainfall in the Apennines, combined with a temperate-cool climate. Because of climate change, the presence of silver fir, although still widespread, has been dramatically reduced in favour of beech.
The Shebenik-Jabllanicë National Park is a national park in eastern Albania adjacent to the border with North Macedonia. It encompasses 339.277 square kilometres (33,927.7 ha) and is specifically marked by a mountainous landscape supplied with glacial lakes, valleys, dense coniferous and deciduous forests and alpine meadows and pastures. Elevations in the park vary from 300 metres to over 2,200 metres above the Adriatic at the peak of Shebenik and Jabllanica, hence the name. It dwells a number of endangered species that are fast becoming rare in Southern Europe, including the brown bear, gray wolf and balkan lynx. The abundance in wildlife can in part be explained by the variety of vegetation types and remote location.
