Strandzha Nature Park

Strandzha Nature Park is the largest protected area in Bulgaria spanning a territory of 1,161 square kilometres (448 mi2) in the Strandzha Mountain in the extreme south-eastern corner of the country on the border with Turkey. It was established on 25 January 1995 to protect ecosystems and biodiversity of European importance, as well as the traditional cultural, historical and folklore heritage of the region. The altitude varies from 710 metres (780 yd) on Gradishte Peak to 0 metres (0 yd) at the Black Sea coast with average length of 50 kilometres (31 mi) from west to east and 20 kilometres (12 mi) from north to south. The nature park is situated in Burgas Province with two towns, Malko Tarnovo and Ahtopol, and several villages within its territory. It includes five nature reserves: Silkosiya, Sredoka, Tisovitsa, Uzunbodzhak and Vitanovo. Silkosiya is the oldest one in Bulgaria, established in 1933, and Uzunbodzhak is included in the World Network of Biosphere Reserves under the UNESCO Man and Biosphere Programme. The whole territory is part of the network of nature protection areas of the European Union, Natura 2000. Strandzha Nature Park falls within two terrestrial ecoregions of the Palearctic temperate broadleaf and mixed forest — the Balkan mixed forests and the Euxine-Colchic deciduous forests.
