The Bulgarian Forest has been known as the Great Bulgarian Forest (Magna silva bulgariva) since Antiquity and the Middle Ages. It used to cover the area from the Black Sea to the Adriatic Sea and from the Danube to the Rhodopes.
At present, forests cover some 30% of the territory of the country, being the most important national resource. In addition to their great significance for biodiversity, forests provide vital economic benefits. Half of the population of Bulgaria is directly dependent on forests and forest resources as sources of incomes, drinking water, and firewood. In addition, the status of the Bulgarian forests is directly affecting the climate and the water reserves of the neighboring Balkan countries and determines the quality of life of eight million Bulgarians and more than fifteen million inhabitants of the Balkans.
Wetlands (lakes, swamps, rivers, etc.) are some of the most productive ecosystems on Earth, preserving unique biodiversity.
At the same time they are a source of irreplaceable resources, securing the livelihood of billions of people.
However, they are among the most threatened habitats on the planet. In Bulgaria, for example, almost 90% of the natural wetlands have been destroyed for the past one and a half century.
