Bulgaria is one of the countries with the greatest biodiversity in Europe.
Between 1991 and 2007, protected areas doubled and now cover 5.14 % of the national land area.
Bulgaria has some of the largest Natura 2000 areas in Europe covering 33.8 % of its territory.
A variety of landscapes, geology and microclimates and thousands of years of human activity have resulted in a rich diversity of species, communities and natural habitats. Bulgaria contains three bio-geographic areas (Alpine, Black Sea and Continental), a variety of communities and ecosystems and almost all major European habitat types.
