Just 20 miles from the city, the Evros Delta is one of Europe's most important habitats with 200,000-acre area, which is on the list of protected areas of the International Ramsar Convention (1971) due to the significant and rare species of plants (more than 300 species), fauna (40 species of mammals, 28 species of reptiles and 46 species of fish) and birds(320 species). Part of the Delta has been designated as a Special Protection Area and is proposed as a Site of Community Interest in the Natura 2000 Network.
