Geography of Bulgaria

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 110994 km2 (111002 km2), 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.

Bulgaria features notable diversity with the landscape ranging from the snow-capped peaks in Rila, Pirin and the Balkan Mountains to the mild and sunny Black Sea coast and southernmost valleys; from the typically continental Danubian Plain (ancient Moesia) in the north to the strong Mediterranean climatic influence in the valleys of Macedonia and in the lowlands in the southernmost of Thrace, the lowest parts of the Upper Thracian Plain, along the Maritsa River, the Southern Bulgarian Black Sea Coast. Most of the country is situated within the humid continental climate region, with Alpine climate in the highest mountains and subtropical climate in the southernmost regions.

The country has a dense river network but with the notable exception of the river Danube, rivers are mostly short and with low water flow. The average annual precipitation is 670 mm; the rainfall is lower in the lowlands and higher in the mountains. The driest region is Dobrudzha in the north-eastern part of the Danubian Plain (450 mm), while the highest rainfall has been measured in the upper valley of the river Ogosta in the western Balkan Mountains (2293 mm).

Bulgaria has substantial land in agriculture and forest. In 2006 land use and land cover was 5% intensive human use, 52% agriculture including pasture, 31% forest, 11% woodland-shrub, grassland, and non-vegetated, and 1% water.

Phytogeographically, Bulgaria straddles the Illyrian and Euxinian provinces of the Circumboreal Region within the Boreal Kingdom. The country falls within six terrestrial ecoregions of the Palearctic realm: Balkan mixed forests (main), Rodope montane mixed forests (main in the mountains), Euxine-Colchic deciduous forests, Aegean and Western Turkey sclerophyllous and mixed forests, East European forest steppe and Pontic–Caspian steppe.

Boundaries and territory
The borders of Bulgaria have a total length of 2,245 km; of them 1,181 km are land boundary and 686 km are formed by rivers. The coastline is 378 km.

The northern border with Romania is 609 km. Most of the frontier (470 km) is formed by the river Danube from the mouth of the river Timok in the west to the city of Silistra in the east. The land border from Silistra to Cape Sivriburun at the Black Sea is 139 km long. The Danube, with steep bluffs on the Bulgarian side and a wide area of swamps and marshes on the Romanian side, is crossed by two bridges – New Europe Bridge between Vidin and Calafat, and Danube Bridge between Ruse and Giurgiu. There are 48 Bulgarian and 32 Romanian islands along the river Danube; the largest one, Belene (41 km2), belongs to Bulgaria. The land frontier has three border crossings at Silistra, Kardam and Durankulak at the Black Sea. It is also crossed by a major gas pipeline transporting natural gas from Russia to Bulgaria. The eastern border (378 km) is maritime and encompasses the Bulgarian Black Sea Coast from Cape Sivriburun in the north to the mouth of the Rezovo River in the south. Bulgaria's littoral forms 1/10 of the total Black Sea coastline, and includes two important gulfs, the Gulf of Varna and the Gulf of Burgas, harbouring the country's two major ports.

The southern border is 752 km long, of them 259 km are with Turkey and 493 km are with Greece. The Bulgaria–Turkey frontier runs from the mouth of the Rezovo River in the east through the Strandzha Mountains and the Dervent Heights, crosses the river Tundzha at the village of Matochina and ends at the river Maritsa at the village of Kapitan Andreevo. There are three border crossings at Malko Tarnovo, Lesovo and Kapitan Andreevo. The border with Greece runs from Kapitan Andreevo through several ridges of the Rhodope Mountains, generally following the watershed of the rivers Arda and Vacha on the Bulgarian side, runs through the Slavyanka Mountain, crosses the river Struma at the village of Kulata and runs through the crest of the Belasitsa Mountain to the Tumba Peak. There are six border checkpoints at Svilengrad, Ivaylovgrad, Makaza, Zlatograd, Ilinden and Kulata.

The western border is 506 km long, of them 165 km are with North Macedonia and 341 km are with Serbia. The frontier with North Macedonia runs from the Tumba Peak in the south through the mountains of Ograzhden, Maleshevo, Vlahina and Osogovo up to mount Kitka. There are three border crossings near the town of Petrich and at the villages of Logodazh and Gyueshevo. The border with Serbia runs from Kitka through the mountainous region Kraishte, including the Ruy Mountain, crosses the valley of the river Nishava, runs through the main watershed of the western Balkan Mountains and follows the river Timok for 15 km until its confluence with the Danube. There are five border checkpoints at Dolno Uyno, Strezimirovtsi, Kalotina, Vrashka Chuka and Bregovo.

Topography
The relief of Bulgaria is varied. In the relatively small territory of the country there are extensive lowlands, plains, hills, low and high mountains, many valleys and deep gorges. The main characteristic of Bulgaria's topography is four alternating bands of high and low terrain that extend east to west across the country. From north to south, those bands, called geomorphological regions, are the Danubian Plain, the Balkan Mountains, the Transitional region and the Rilo-Rhodope region. The easternmost sections near the Black Sea are hilly, but they gradually gain height to the west until the westernmost part of the country is entirely high ground.

Table, showing the distribution of the height zones in Bulgaria: More than two-thirds of the country is plains, plateaus, or hilly land at an altitude less than 600 m. Plains (below 200 m) make up 31% of the land, plateaus and hills (200 to 600 m) 41%, low mountains (600 to 1,000 m) 10%, medium-high mountains (1,000 to 1,500 m) 10%, and high mountains (over 1,500 m) 3%. The average altitude of Bulgaria is 470 m.

The contemporary relief of Bulgaria is a result of continuous geological evolution. The Bulgarian lands were often submerged by ancient seas and lakes, some land layers rose others sank. Volcanic eruptions were common both on land and in the water basins. All three main groups of rocks, magmatic, sedimentary and metamorphic, are found in the country. The oldest rock formations in Bulgaria date from the Precambrian period than 500 million years ago. During the Archean, Proterozoic and Paleozoic eras (4.0 billion to 252 million years ago) the magmatic rocks were formed. Throughout most of that period the only land areas were Rila, Pirin and the western Rhodope Mountains. The Mesozoic era (252 million to 66 million years ago) saw the beginning of the Alpine orogeny that has formed the mountain ranges of the Alpide belt, including the Balkan Mountains and Sredna Gora. The Cenozoic era (since 66 million years ago) is characterized with active tectonic processes, the definitive formation of the Balkan Mountains, the formation of grabens and horsts in Rila, Pirin and Kraishte region.

Examples of rock formations in Bulgaria:

Exogenous processes such as weathering, erosion and sedimentation have an important impact on modelling the land surface and creating rock formations. The exogenous processes have formed stone rivers in Vitosha; screes in the Balkan Mountains, Rila and Pirin; earth pyramids in Melnik, Stob and Katina; landslides, mainly along the Danube banks and the northern Black Sea coast; fluvial terraces; aeolian forms, such as dunes; karst forms, including numerous caves, sinkholes, ponors, etc.

Danubian Plain
The Danubian Plain encompasses the Moesian plate and extends from the river Timok in the west to the Black Sea in the east and from the river Danube in the north to the Balkan Mountains in the south, covering 31,520 km2, or almost 1/3 of Bulgaria's total area. Its width varies from 25 to 30 km in the west to 120 km in the east. The highest point is Tarnov Dyal (502 m) on the Shumen Plateau; the average altitude is 178 m. As a result of the rock weathering processes the relief is uneven with fertile alluvial plains along the Danube (Vidinska, Chernopolska, Zlatia, Belenska, Pobrezhie, Aidemirska), and hilly terrain in the remaining area, including plateaus in the east. The altitude rises from west to east. The valleys of the rivers Vit and Yantra divide the Danubian Plain into three parts – western, central and eastern. The topography of the plain is characterized with hilly heights and plateaus. Most of the heights and all plateaus are situated in the eastern parts. There are 14 basalt mounds between Svishtov and the village of Dragomirovo.

The predominant soil types are loess in the north, reaching a depth of up to 100 m at the banks of the Danube, and chernozem in the south. The climate is temperate. The flat relief and the openness of plain to the north facilitate arrival of moist air masses in spring, summer and autumn. In winter the Danubian Plain falls under the influence of the Eastern European anticyclone, which brings cold Arctic air masses. The mean temperature in January is −1 °C and in July is 24 °C, making it the geomorphological region with the highest average annual amplitude in Bulgaria – 25 °C.

Balkan Mountains
The Balkan Mountains range is a geological continuation of the Carpathian Mountains, forming part of the Alpine-Himalayan orogenic belt. This region is subdivided into two geomorphological units, the Pre-Balkan and the Balkan Mountains, also known in Bulgarian as Стара Планина – "Old Mountain". Their average altitude is 370 m and 735 m, respectively. Its total area is 26,720 km2, of them the Pre-Balkan spans 15,730 km2 and the Balkan Mountains – almost 11,000 km2. The mountain range stretches from the valley of the river Timok in the west to Cape Emine at the Black Sea coast in the east, spanning a length of 555 km and width between 20 and 70 km. The Balkan Mountains are divided into western, central and eastern part by the Zlatitsa and Vratnik Passes. The range is highest in its central part, which includes Botev Peak at 2,376 m; the altitude drops slowly to the east until it reaches the sea. The relief is varied, with many mountain passes, gorges and landforms. The southern slopes are steeper than the northern. For the most part the Balkan Range defines the most important watershed in Bulgaria with rivers draining north to the Danube or south to the river Maritsa and the Aegean Sea. Several rivers in the east drain directly into the Black Sea. In the west, the river Iskar forms a 65-km long gorge that runs north through the mountains.

Transitional region
The Transitional geomorphological region encompasses the territory between the Balkan Mountains and the Rilo-Rhodope Massif and has complex, mosaic relief composed mainly of medium-high and low mountains, valleys and plains. The altitude decreases from west to east. This region includes the Sub-Balkan valleys; the mountains and valleys of the Kraishte region, such as Ruy Mountain, Miloslavska planina and Milevska Planina; the mountains Lyulin, Vitosha, Sredna Gora, Strandzha and Sakar; the Dervent Heights; as well as the fertile Upper Thracian Plain. The highest point is Cherni Vrah in Vitosha at 2,290 m.

The Sub-Balkan valleys include nine valleys, situated between the Balkan Mountains in the north and Vitosha and Sredna Gora in the south. With an area of 1,186 km2 and an average altitude of 550 m, Sofia Valley is the largest of the nine and contains the nation's capital, Sofia. The Rose Valley encompasses the valleys of Karlovo and Kazanlak and is renowned for its rose-growing industry, which has been thriving there for centuries, producing 85% of the world's rose oil. The Kazanlak Valley is also known as the Valley of the Thracian Kings due to the extremely high concentration and variety of monuments of the Thracian culture.

Srednogorie region stretches between the Sub-Balkan valleys in the north and the Rilo-Rhodope Massif in the south and from west to east includes the mountains Zavalska Planina, Viskyar, Lyulin, Vitosha, Plana and Sredna Gora. The largest of these, Sredna Gora, is 280 km and reaches a maximum width of 50 km. Kraishte region covers the western parts of the Transitional geomorphological region and consists of two almost parallel mountain groups, Ruysko–Verilska and Konyavsko–Milevska, as well as numerous valleys.

The Upper Thracian Plain encompasses the middle valley of the river Maritsa and has a roughly triangular shape, situated between Sredna Gora in the north, the Rhodope Mountains in the south and Sakar Mountain in the east. The lowland is 180 km long and up to 50 km wide, spanning an area of 6,000 km2. To the east are located the Burgas Plain, Svetliyski Heights, Manastirski Heights, Dervent Heights, and the low mountains Sakar and Strandzha.

Rilo-Rhodope region
The Rilo-Rhodope geomorphological region covers the south-western regions of Bulgaria and includes the Rhodope Mountains, Rila, Pirin, Osogovo, Vlahina, Maleshevo, Ograzhden, Slavyanka and Belasitsa, as well as the valleys of the rivers Struma and Mesta. The Rhodopes are the most extensive mountain range in Bulgaria, spanning an area of 14,730 km2 with an average altitude of 785 m, characterized with gentle and densely forested slopes. Their length from west to east is 249 km and reach width of 100 km. The altitude decreases from west to east.

To the west are located Rila and Pirin, Bulgaria's two highest mountains. Rila includes Mount Musala, whose 2,925 m peak is the highest in the Balkan Peninsula, while Pirin's highest peak Vihren at 2,915 m is the third-highest in the Balkans. Both Rila and Pirin have rocky peaks, stony slopes, extensive Alpine zone and hundreds glacial lakes. Further west is the Osogovo–Belasitsa mountain group along the border with North Macedonia, whose highest peak is Ruen in Osogovo at 2,251 m.

Black Sea coast
The Bulgarian Black Sea Coast has a total length of 378 km from Durankulak in the north to the mouth of the river Rezovska in the south. The northernmost section between the Bulgarian-Romanian border to Shabla has extensive sandy beaches and several coastal lakes, then the elevation rises as the coast reaches Cape Kaliakra, with 70 m high vertical cliffs. Near Balchik and Kavarna the limestone rocky coast is cut by wooded valleys. The landscape around the coast resorts of Albena and Golden Sands is hilly, with a clearly expressed land                                                    slides. Dense forests at the mouth of the river Batova mark the beginning of Frangensko plateau. South of Varna the coastline is densely wooded, especially at the alluvial longose groves of the Kamchia Biosphere Reserve. Cape Emine marks the end of the Balkan Mountain and divides the Bulgarian Black Sea coast in northern and southern parts. The southern section has wide and long beaches, with a number of small bays and headlands. All Bulgarian Black Sea islands are situated in the southern coast: St. Anastasia, St. Cyricus, St. Ivan, St. Peter and St. Thomas. Sandy beaches occupy 34% of the Bulgarian coastline. The two most important gulf are the Gulf of Varna in the north and the Gulf of Burgas in the south, which is the largest in the Bulgarian Black Sea coast.

Climate
Considering its relatively small area, Bulgaria has variable and complex climate. The country occupies the southernmost part of the continental climatic zone, with small areas in the south falling within the Mediterranean climatic zone. The continental zone is predominant, because continental air masses flow easily into the unobstructed Danubian Plain. The continental influence, stronger during the winter, produces abundant snowfall; the Mediterranean influence increases during the second half of summer and produces hot and dry weather. Bulgaria is subdivided into five climatic zones: continental zone (Danubian Plain, Pre-Balkan and the higher valleys of the Transitional geomorphological region); transitional zone (Upper Thracian Plain, most of the Struma and Mesta valleys, the lower Sub-Balkan valleys); continental-Mediterranean zone (the southernmost areas of the Struma and Mesta valleys, the eastern Rhodope Mountains, Sakar and Strandzha); Black Sea zone along the coastline with an average length of 30–40 km inland; and alpine zone in the mountains above 1000 m altitude (central Balkan Mountains, Rila, Pirin, Vitosha, western Rhodope Mountains, etc.).

Despite the large distance, the most important climate-forming factor is the Atlantic Ocean through the atmospheric circulation of the Icelandic cyclone and the Azores anticyclone, which bring cool and rainy weather in summer and relatively mild weather with abundant snowfall in winter. The influence of the Mediterranean Sea is strongest in the southern parts of Bulgaria, mainly through the Mediterranean cyclones. Due to its small area, the influence of the Black Sea only affects a 30–40 km long strip along the coastline, mainly in summer, when the daily breeze circulation is most pronounced.

Another important factor is the relief. The Bulgarian mountains and valleys act as barriers or channels for air masses, causing sharp contrasts in weather over relatively short distances. The Balkan Mountains form a barrier which effectively stops the cool air masses coming from the north and the warm masses from the south. The barrier effect of the Balkan Mountains is felt throughout the country: on the average, northern Bulgaria is about one degree cooler and receives about 192 mm more rain than lowlands of southern Bulgaria. The Rilo-Rhodope Massif bars the warm Mediterranean air masses and limits the Mediterranean influence to the southern valleys of the rivers Struma, Mesta, Maritsa and Tundzha, despite the close proximity of the Aegean Sea.

The mean annual temperature in Bulgaria is 10.6 °C and varies from 2.2 °C at the nation's highest peak Musala to 14.7 °C (1991-2021 Climate data) at the town of Sandanski in the southern Struma valley. The average temperature in the Danubian Plain is 11.4 °C, in the Upper Thracian Plain 13.9 °C, in the lower mountains 8.1 °C and in the higher mountains 2.4 °C. The highest absolute temperature was measured at the town of Sadovo in 1916 45.2 °C; the lowest absolute temperature was measured at the town of Tran in 1947 –38.3 °C. The highest temperature in the lowlands and the hilly regions is in July, while in the higher mountains the warmest month is August. The lowest temperature is measured in January (Dragoman - average monthly temperature: -2, Ahtopol: + 4,2) and February, respectively. Many valleys experience regular temperature inversions and fogs in winter. The country's lowest absolute temperature was measured during an inversion in the Tran valley : −38.3 °C.

The average precipitation in Bulgaria is about 670 mm. It is uneven in terms of seasons and territory. In northern Bulgaria the highest precipitation is in May–June, while in southern Bulgaria it is in winter. The average amount of precipitation also varies in term of altitude – from 450 to 850 mm in the plains to 850–1200 mm. The lowest mean precipitation is in the eastern part of Dobrudzha and the Burgas Plain (450 mm) and in the area between Plovdiv and Pazardzhik (500 mm); the highest rainfall falls in the mountains – the Petrohan Pass in the western Balkan Mountains and Zlatograd in the Rhodope Mountains. The highest annual rainfall was measured in 1957 in the upper valley of the river Ogosta in the western Balkan Mountains (2293 mm); the highest daily rainfall was recorded at Saints Constantine and Helena resort (342 mm) near Varna in 1951. The total annual amount of the rainfall is 74 billion km3; of them 70% evaporate, 20% flow into the rivers and 10% soak into the soil. Most of the country is affected by droughts in June and August. The snow cover lasts from 20 to 30 days in the lowlands to 9 months in the highest mountains.

Hydrography
Bulgaria has a dense network of about 540 rivers, but with the notable exception of the Danube, most have short length and low water-level. The density is highest in the mountain areas and lowest in Dobrudzha, the Danubian Plain and the Upper Thracian Plain. There are two catchment basins: the Black Sea (57% of the territory and 42% of the rivers) and the Aegean Sea (43% of the territory and 58% of the rivers) basins.

The Balkan Mountains divide Bulgaria into two nearly equal drainage systems. The larger system drains northward to the Black Sea, mainly by way of the Danube. This system includes the entire Danubian Plain and a stretch of land running 48–80 km inland from the coastline in the south. The Danube gets slightly more than 4% of its total volume from its Bulgarian tributaries. As it flows along the northern border, the Danube averages 1.6 to 2.4 km in width. The river's highest water levels usually occur during the May floods; it is frozen over an average of 40 days per year. The longest river located entirely in Bulgarian territory, the Iskar, with a length of 368 km and a catchment area of 8,640 km2, is the only Bulgarian Danubian tributary that does not rise in the Balkan Mountains. Instead, the Iskar has its origin in the Rila Mountains. It passes through Sofia's eastern suburbs and crosses the Balkan Mountains through a spectacular 65 km–long gorge. Other important tributaries of the Danube include the rivers Lom, Ogosta, Vit, Osam and Yantra. The longest river flowing directly to the Black Sea is the Kamchiya (254 km), while other rivers include the Batova, Provadiya, Aheloy, Ropotamo, Veleka and Rezovo.

The Aegean Sea catchment basin drains the Thracian Plain and most of the higher lands to the south and southwest. Several major rivers flow directly to the Aegean Sea. Most of these streams fall swiftly from the mountains and have cut deep, scenic gorges. The 480 km–long Maritsa (of them 321 km in Bulgaria) and its tributaries drain all of the western Thracian Plain, all of Sredna Gora, the southern slopes of the Balkan Mountains, and the northern slopes of the eastern Rhodopes. After it leaves Bulgaria, the Maritsa forms most of the Greco-Turkish border. Maritsa's major tributaries are the Tundzha, Arda, Topolnitsa, Vacha, etc. The other Bulgarian rivers flowing directly to the Aegean are the Struma and the Mesta.

Bulgaria has around 400 natural lakes with a total area of 95 km2 and volume of 278 million km3. The limans and lagoons along the Black Sea coast include from north to south Lake Durankulak, Lake Shabla, Lake Varna, Lake Beloslav, Lake Pomorie, Lake Atanasovsko, Lake Burgas and Lake Mandrensko. Of them, Lake Burgas is the most extensive with 27,6 km2 and Lake Varna has the largest volume with 165,5 million m3. The lakes along the Danube were dried to clear land for agriculture with the notable exception of the UNESCO World Heritage Site Lake Srebarna. There are 170 glacial lakes in Rila and 164 in Pirin. They are an important tourist asset. The most renown lakes include the Seven Rila Lakes, Popovo Lake, Banderishki Lakes, Vasilashki Lakes, Vlahini Lakes, etc. Swamps and marshes include Alepu, Arkutino, Aldomirovtsi Marsh, Dragoman Marsh, etc. There are around 2,200 reservoirs with a total volume of c. 7 billion km3. The largest ones are Iskar Reservoir, Ogosta Reservoir, Dospat Reservoir, Batak Reservoir, Kardzhali Reservoir, Ivaylovgrad Reservoir, Studen Kladenets, Koprinka Reservoir, Ticha Reservoir, etc.

Bulgaria is rich in mineral waters, with 225 mineral springs and a total discharge of 5000 L/s, mainly in the south-western and central parts of the country along the faults between the mountains. Most of them, 148, are situated in southern Bulgaria, while the other 77 are in the northern part of the country. The springs in the north tend to be with cool water, while those to the south are mainly warm and hot. The hottest spring in Bulgaria and the Balkans is situated in Sapareva Banya and reaches 101.4 °C. The Bulgarian word for spa, баня, transliterated as banya, appears in some of the names of more than 50 spa towns and resorts. They are located in several zones: Balkan Mountains zone (Varshets, Shipkovo, Voneshta Voda), Srednogorie zone (Sofia, Ovcha kupel, Bankya, Pancharevo, Strelcha, Hisarya, Banya, Pavel Banya), Maritsa zone (Kostenets (town), Kostenets (village), Dolna Banya, Momin Prohod), Rilo-Rhodope zone (Devin, Velingrad, Banite, Beden, Mihalkovo, Sapareva Banya), Struma zone (Kyustendil, Sandanski, Ognyanovo, Marikostinovo, Dobrinishte).

Soils
The soil cover of Bulgaria is diverse. The soil resources of the country are adequately researched and include 17 soil types and 28 sub-types. Of them, six types form 88.7% of the soil cover: cinnamon soils (22.0%); chernozem (20.4%); grey forest soils (17.0%); brown forest soils (14.8%); alluvial soils (9.0%) and smolnitsi (5.4%).

There are three soil zones. The Northern forest-steppe zone covers the Danubian Plain and the Pre-Balkan up to 600–700 m altitude. The Danubian Plain is characterised by the fertile black earth chernozem, that accounts for 54% of the zone's area, while the Pre-Balkan is dominated by grey forest soils (39%), which have good physical characteristics but are low in organic matter and phosphorus. The Southern xerothermal zone encompasses Southern Bulgaria up to 700–800 m altitude and includes several specific soil types due to the more diverse topography and climate. The most common soil types are the cinnamon forest soils with acidic (cinnamonic) traces, smolnitsi and yellow-podzolic soils. The Mountain zone covers the mountainous regions above 700–800 m altitude and has a zonal soil cover. The brown forest soils are distributed at altitudes of 1000–2000 m, the dark mountain forest soils can be found at 1700–2200 m altitude and the mountain meadow soils – above 1700 m. These soils are typically shallow and prone to erosion and are usually acid to strongly acid.

Mineral resources
There are approximately 60 types of minerals that are extracted commercially in Bulgaria. The mineral resources are divided into three groups: fossil fuels, metals and industrial minerals.

The fossil fuels include coal, petroleum and natural gas. Bulgaria possesses significant reserves of coal estimated at 4,8 billion tons. More than 92% of them, or 4,5 billion tons, is lignite, which is the lowest rank of coal due to its relatively low heat content but is widely used for electricity generation. With reserves of 2,856 billion tons Maritsa Iztok, situated in the Upper Thracian Plain, is by far the largest coal basin in the country which powers Maritsa Iztok Complex, the largest energy complex in South-Eastern Europe. Other lignite basins include Sofia valley (reserves of 870 million tons), Elhovo (656 million tons), Lom (277 million tons), Maritsa Zapad (170 million tons). The reserves of sub-bituminous coal are 300 million tons, situated mainly near Bobov Dol, Pernik and Burgas. The recoverable reserves of bituminous coal and anthracite are insignificant – only 10 and 2,5 million tons respectively. However, there is a huge basin of bituminous coal in Southern Dobruja with estimated reserves of over 1 billion tons but its large depth (1370–1950 m) is an obstacle for its commercial exploitation.

The Bulgarian exclusive economic zone has a total size of 110,879 km2 in the Black Sea. Petroleum and natural gas are found in northern Bulgaria and its EEZ in the Black Sea. Crude oil is extracted in Dolni Dabnik and Gigen in Pleven Province and in Tyulenovo, Dobrich Province. The proven reserves are 20 million tons but there are prospects for new discovering in the EEZ. Gas fields have been discovered off cape Kaliakra (reserves of 3 billion m3), Deventsi (6 billion m3), between Lovech and Etropole (est. 22 billion m3), as well as near Devetaki and Butan. It is estimated that the 14,220 m2 Khan Asparukh Block in the northern section of the Bulgarian EEZ has natural gas reserves of 100 billion m3.

Bulgaria has significant reserves of metal ores, especially copper, zinc and lead, situated mainly in the southern half of the country. The two largest iron ore mines are located in Kremikovtsi near Sofia and Krumovo, Yambol Province with total reserves of 430 million tons. Manganese ore is extracted near Obrochishte in Dobrich Province (reserves of 85 million tons), as well as in the provinces of Sofia and Varna. The reserves of chromium are small and are scattered in the Rhodope Mountains. Bulgaria possesses important reserves of lead and zinc, of them 60% are situated in the southern reaches of the Rhodope Mountains along the border with Greece at Madan, Zlatograd, Madzharovo, Rudozem, Laki, etc. Other mines are located near Ustrem and Gyueshevo. The reserves of copper ore are also significant, situated mainly at Asarel Medet near Panagyurishte, Elatsite mine near Etropole (650 million tons), Elshitsa, Medni Rid near Burgas, etc. There is gold near Tran, Chelopech and Madzharovo, as well as small quantities of platinum, silver, molybdenum, nickel and tungsten.

Bulgaria is rich in industrial minerals, with 70 types being mined. There are important reserves of rock salt near the town of Provadia (4,4 billion tons). Solnitsata, an ancient town located nearby is believed by Bulgarian archaeologists to be the oldest in Europe and was the site of a salt production facility approximately six millennia ago. The reserves of kaolinite are estimated at 70 million tons, situated mainly in north-eastern Bulgaria – Kaolinovo, Todor Ikonomovo, Senovo and Vetovo. Marble is extracted in the mountainous regions – Pirin, Rhodopes, Strandzha, the western Balkan Mountains. There are important quantities of limestone, gypsum, baryte, perlite, feldspar, granite, etc.

Biodiversity
The interaction of complex climatic, hydrological, geological and topographical conditions make Bulgaria one of the most biologically diverse countries of Europe. Phytogeographically, Bulgaria straddles the Illyrian and Euxinian provinces of the Circumboreal Region within the Boreal Kingdom. The country falls within six terrestrial ecoregions of the Palearctic realm: Balkan mixed forests, Rodope montane mixed forests, Euxine-Colchic deciduous forests, Aegean and Western Turkey sclerophyllous and mixed forests, East European forest steppe and Pontic–Caspian steppe. Around 35% of Bulgaria's land area consists of forests, which include some of the oldest trees in the world, such as Baikushev's pine and the Granit oak. Bulgaria's flora contains between 3,800 and 4,200 vascular plant species of which 170 are endemic and 150 are considered endangered. There more than 6,500 species of non-vascular plants and fungi. Bulgaria's vertebrate fauna is among the most diverse in Europe. The zoogeographical regions are three: the Eurosiberian region, encompassing the Danubian Plain and the mountainous regions of the country; the Irano-Turanian Region encompassing Southern Dobrudzha; and the Mediterranean region that includes the Upper Thracian Plain, the lower Struma valley and the Black Sea coast. Bulgaria is inhabited by around 100 mammal species, including Brown bears, Grey wolves, Wild boars, Golden jackals, Red foxes, Wildcats, Red deers, Roe deers, European fallow deers, European hares, Southern white-breasted hedgehogs, Badgers, Marbled polecats, European polecats, European pine martens, four species of Oceanic dolphins, Mediterranean monk seals among other. Protection, reintroductions and repopulations like those of the European bison, the Eurasian beaver, and the Eurasian lynx are intended and reported.

The avian fauna is represented by 434 species of birds, which is the second highest number in Europe. Almost all species of the True owls live in the country, also White stork, Common crane, Demoiselle crane. Important conservation species are the Eastern imperial eagle, the Cinereous, Griffon, Egyptian and the Bearded vultures, the Great white pelican, the Dalmatian pelican, etc.

The reptiles and the amphibians found in Bulgaria are 38 and 20 species respectively. There are four turtle and two tortoise species of four families – Cheloniidae, Emydidae, Geoemydidae and Testudinidae; fourteen lizard species of four families – Anguidae, Gekkonidae, Lacertidae and Scincidae; and eighteen snake species of four families – Boidae, Colubridae, Typhlopidae and Viperidae.

The ichthyofauna of the country has not been fully researched, but there is a rich variety with various species of Sturgeons, Black sea shark, Longnose spurdog, Thornback ray, Common stingray, Northern pike, European eel, etc. As of 2000 there are 207 fish species.

There are an estimated 27,000 species of insects and other invertebrates.

Concern about biodiversity conservation remains strong within the country. In 1998 the Government of Bulgaria approved the National Biological Diversity Conservation Strategy, which was inspired by the Pan European Strategy for Biological and Landscape Diversity. Bulgaria has some of the largest Natura 2000 areas in the European Union covering 33.8% of its territory. The national policy for governing and management of the protected areas is implemented by the Ministry of Environment and Water. Bulgaria's biodiversity is conserved in three national parks, 11 nature parks and 55 nature reserves. Of them, Pirin National Park, Srebarna Nature Reserve and nine forest reserves within the Central Balkan National Park are included in the UNESCO World Heritage List. Spanning a territory of 1,161 square kilometres Strandzha Nature Park is the largest protected area in the country. Established in 1936 Vitosha Nature Park is the oldest in Bulgaria and in the Balkan Peninsula.

Politics of Bulgaria

The politics of Bulgaria take place in a framework of a parliamentary representative democratic republic, whereby the prime minister is the head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the National Assembly. The Judiciary is independent of the executive and the legislature.

After forty-five years of single party system, Bulgaria became an unstable party system in 1989. This system was dominated by democratic parties and opposition to socialists – the Union of Democratic Forces and several personalistic parties and the post-communist Bulgarian Socialist Party or its creatures, which emerged for a short period of time in the past decade. Personalistic parties could have been seen in the former governing (from 2001 to 2005) Simeon II's NDSV party and Boyko Borisov's GERB party.

Bulgaria has generally good freedom of speech and human rights records as reported by the US Library of Congress Federal Research Division in 2006, while Freedom House listed it as "free" in 2020, giving it scores of 33 for political rights and 45 for civil liberties. However, in 2014, there were some concerns that the proposed new Penal Code would limit freedom of the press and assembly, and as a consequence freedom of speech.

Parliamentary
After the fall of the communism in 1989, the former communist party was restructured and succeeded by the Bulgarian Socialist Party (BSP), which won the first post-communist elections for the Constitutional Assembly in 1990 with a small majority. Meanwhile, Zhelyu Zhelev, a communist-era dissident from the new democratic party - Union of Democratic Forces (abbreviated in Bulgarian as SDS), was elected president by the Assembly in 1990. In the first years after the change of regime, Bulgarian politics had to (re)establish the foundations of a democratic society in the country after nearly fifty years of de facto totalitarian communism. The so-called period of transition (from a Soviet socialist model to an economic structure focused on development through economic growth) began in the early 1990s. The politics of Bulgaria was aimed at joining the European Union and the NATO fold, as the alliances were recognised to have political agendas similar to the goals of the new Bulgarian democracy.

In contemporary Bulgaria, the government and its leader - the Prime Minister, have more political influence and significance than the President. Thus, the parliamentary elections set the short-term social and political environment in the country since the cabinet (chosen by the Prime Minister and approved by the parliament) decides how the country is governed while the President can only make suggestions and impose vetoes.

In the first parliamentary elections held under the new constitution of Bulgaria, in October 1991, the Union of Democratic Forces (SDS) party won a plurality of the seats, having won 110 out of the 240 seats, and created a cabinet alone with the support of the Movement for Rights and Freedoms—a liberal party (in Bulgarian abbreviated: DPS) which is widely perceived as a party of the ethnic Turks minority in Bulgaria. Yet, their government collapsed in late 1992, and was succeeded by a technocratic team put forward by the Bulgarian Socialist Party (BSP), which served until 1994 when it also collapsed. The President dissolved the government and appointed a provisional one to serve until early parliamentary elections could be held in December.

BSP won convincingly these elections in December 1994 with a majority of 125 seats out of the 240. Due to the severe economic crisis in Bulgaria during their government, BSP's cabinet collapsed and in 1997 a caretaker cabinet was appointed by the President, again, to serve until early parliamentary elections could be held in April 1997.

The April 1997 elections resulted in a landslide victory for the SDS, winning a majority of 137 seats in parliament, and allowing them to form the next government. This proved to be the first post-communist government that did not collapse and served its full 4-year term until 2001.

In 2001, the former monarch of Bulgaria Simeon Saxe-Coburg-Gotha returned to power, this time as Prime Minister with his National Movement Simeon II (in Bulgarian abbreviated: NDSV), having won half (120) of the seats. His party entered a coalition with the DPS and invited two functionaries of the BSP (who sat as independents). In opposition were the two previously governing parties - the Socialist Party and the Union of Democratic Forces. In the four years in opposition the SDS suffered the defection of numerous splinter groups. The ruling party NDSV itself ruptured into a pro-right core and a pro-liberal fringe group. Bulgaria entered NATO in 2004.

In the aftermath, the BSP won the parliamentary elections in 2005 with 82 out of the 240 seats, but as it did not get the majority of the seats, a coalition government was formed by the three biggest parties - BSP, NDSV and DPS. The elections also put in parliament some of the right-wing parties, as well as the extreme-right nationalist coalition led by the party Ataka as an answer to the former coalition government of NDSV with DPS. Bulgarian entered the European Union in 2007.

In the parliamentary elections of 2009, the centre-right party of Boyko Borisov, the mayor of Sofia, GERB, won with 117 seats. The party formed a minority government with the support of the right-wing parties. Once the governing party - the National Movement Simeon II did not amass enough votes to enter the parliament. The austerity measures required in the stagnation of the Global Financial Crisis led to massive protests and the resignation of the cabinet in early 2013, months before the end of GERB's term.

In the early elections the former opposition party BSP received highest vote from the people. The socialist party chose the non-party former Minister of Finance Plamen Oresharski to form a cabinet. His cabinet was supported by the BSP and the DPS, opposed by GERB, while Ataka was absent.

Only two weeks after its initial formation the Oresharski government came under criticism and had to deal with large-scale protests some with more than 11 000 participants. One of the main reasons for these protests was the controversial appointment of media mogul Delyan Peevski as a chief of the National Security State Agency. The protests continued over the lifetime of the Oresharski government. In all, the government survived 5 votes of no-confidence before voluntarily resigning. Following an agreement from the three largest parties (GERB, BSP and DPS) to hold early parliamentary elections for 25 March 2016, the cabinet agreed to resign, with the resignation of the cabinet becoming a fact on 13 January 2016. The next day parliament voted 180-8 (8 abstained and 44 were absent) to accept the government's resignation. Following the vote, President Plevneliev offered the mandate to GERB to try and form government, but it was refused. The next day the BSP returned the mandate as well. On 21 January, the DPS refused the mandate as well. Finally, on 26 January, a caretaker government led by Georgi Bliznashki was sworn into office and the Oresharski government was officially dissolved.

As agreed, parliamentary elections were held on 25 March 2016 to elect the 43rd National Assembly. GERB became the largest party, winning 84 of the 240 seats with around a third of the vote. A total of eight parties won seats, the first time since the beginning of democratic elections in 1990 that more than seven parties entered parliament. After being tasked by President Rosen Plevneliev to form a government, Borisov's GERB formed a coalition with the Reformist Bloc,  had a partnership agreement for the support of the Alternative for Bulgarian Revival, and also had the outside support of the Patriotic Front. The cabinet of twenty ministers was approved by a majority of 136–97 (with one abstention). With the support of the coalition partner (the Reformist Bloc) members of the parties in the Bloc (Democrats for a Strong Bulgaria (DSB), Union of Democratic Forces (SDS), Bulgaria for Citizens Movement (DBG) and Bulgarian Agrarian National Union (BZNS)) were chosen for Minister positions. The vice chairman of the Alternative for Bulgarian Revival party Ivaylo Kalfin was voted for Depute Prime Minister and Minister of Labor and Social Policy.

In May 2017, Boyko Borisov was re-elected as Prime Minister of Bulgaria for the second time. Borisov had resigned and called early elections after his conservative GERB party lost the presidential elections previous year. He formed a coalition government with nationalist VMRO-BND and National Front for Salvation of Bulgaria. The Socialist Party and the Turkish DPS party formed the opposition.

The 2020–2021 Bulgarian protests were triggered on 9 July 2020 when the Presidency of Bulgaria was raided by police and prosecutors as a result of a long-lasting conflict between the prime minister Boyko Borisov and the president Rumen Radev. In April 2021, Borisov's party, center-right, pro-European GERB won the parliamentary election. It was again the largest party of the parliament but it did not get the absolute majority, indicating difficult coalition talks. All other parties refused to form a government, and after a brief deadlock, another elections were called for July 2021, with Stefan Yanev serving as an interim Prime Minister of a caretaker cabinet until then.

In the July 2021 snap election, an anti-elite party called There Is Such a People (ITN) finished first with 24.08 percent and former Prime Minister Boyko Borisov's GERB-led coalition finished second with 23.51 percent of the vote. A coalition government was unable to be formed, and so a third parliamentary election was scheduled for November 2021 to align with the regularly scheduled presidential election. In the 2021 Bulgarian general election, Kiril Petkov's PP party emerged as surprise victors over the conservative GERB party, which had dominated Bulgarian politics in the last decade. In December 2021, Bulgaria’s parliament formally elected Kiril Petkov as the country's next prime minister, ending a months-long political crisis. The new centrist-led government was a coalition led by Petkov’s anti-corruption We Continue The Change party (PP) with three other political groups: the left-wing Bulgarian Socialist Party, the anti-elite There Is Such A People party, and the liberal group Democratic Bulgaria. They together control 134 seats in Bulgaria’s 240-seat parliament. The cabinet of Kiril Petkov fell after a vote of no confidence of 22 June 2022. President Radev appointed Galab Donev as acting prime minister to lead a caretaker cabinet. Bulgaria's fourth parliamentary elections in less than two years will be held on October 2, 2022.

In April 2023, because of the political deadlock, Bulgaria held its fifth parliamentary election since April 2021. GERB was the biggest, winning 69 seats. The bloc led by We Continue the Change won 64 seats in the 240-seat parliament. In June 2023, Prime Minister Nikolai Denkov formed a new coalition between We Continue The Change and GERB. According to the coalition agreement, Denkov will lead the government for the first nine months. He will be succeeded by former European Commissioner, Mariya Gabriel, of the GERB party. She will take over as Prime Minister after nine months.

Presidential
In 1992, Zhelyu Zhelev won Bulgaria's first presidential elections and served as president until 1997. In the second, the winning President was another member of the Union of Democratic Forces, Petar Stoyanov, who served until 2002. In 2001, the leader of the Bulgarian Socialist Party, Georgi Parvanov defeated Stoyanov. He took office in 2002 and served until 2012, becoming the first president to be reelected, after his successful 2006 campaign. In 2011 GERB candidate Rosen Plevneliev was elected to serve as president from 2012 until January 2017. In 2016 Socialist party candidate, former air force commander Rumen Radev won the presidential election. On 18 January 2017, Rumen Radev was sworn in as the new President of Bulgaria. President Rumen Radev, a vocal critic and rival of prime minister Borisov, announced that he will run for a second five-year term in autumn 2021 presidential elections. In November 2021, President Rumen Radev was easily re-elected in the presidential election with a very low turnout of 34 per cent.

Executive branch
The president of Bulgaria is directly elected for a 5-year term with the right to one re-election. The president serves as the head of state and commander in chief of the armed forces. The President's main duties are to schedule elections and referendums, represent Bulgaria abroad, conclude international treaties, and head the Consultative Council for National Security. The President may return legislation to the National Assembly for further debate—a kind of veto—but the legislation can be passed again by an absolute majority vote.

Legislative branch
The Bulgarian unicameral parliament, the National Assembly or Narodno Sabranie, consists of 240 deputies who are elected for 4-year-terms by popular vote. The votes are for party or coalition lists of candidates for each of the 28 administrative divisions. A party or coalition must garner a minimum of 4% of the vote in order to enter parliament. Parliament is responsible for enactment of laws, approval of the budget, scheduling of presidential elections, selection and dismissal of the prime minister and other ministers, declaration of war, deployment of troops outside of Bulgaria, and ratification of international treaties and agreements.

Judicial branch
The Bulgarian judicial system consists of regional, district and appeal courts, as well as a Supreme Court of Cassation and one Specialized Criminal Court. In addition, there is a Supreme Administrative Court and a system of military courts. The Presidents of the Supreme Court of Cassation and the Supreme Administrative Court as well as the Prosecutor General are elected by a qualified majority of two-thirds from all the members of the Supreme Judicial Council and are appointed by the President of the Republic. The Supreme Judicial Council is in charge of the self-administration and organisation of the Judiciary.

A qualified majority of two-thirds of the membership of the Supreme Judicial Council elects the Presidents of the Supreme Court of Cassation and of the Supreme Administrative Court, as well as the Prosecutor General, from among its members; the President of the Republic then appoints those elected.

The Supreme Judicial Council has charge of the self-administration and organization of the Judiciary.

The Constitutional Court of Bulgaria supervises the review of the constitutionality of laws and statutes brought before it, as well as the compliance of these laws with international treaties that the Government has signed. Parliament elects the 12 members of the Constitutional Court by a two-thirds majority. The members serve for a nine-year term.

Administrative divisions
The territory of the Republic of Bulgaria is divided into provinces and municipalities. In all Bulgaria has 28 provinces, each headed by a provincial governor appointed by the government. In addition, there are 265 municipalities.
