The Danube Delta is the second largest river delta in Europe, after the Volga Delta, and is the best preserved on the continent.
In 1991 agricultural land in the delta surpassed 100,000 hectares, and more than a third of its surface has been affected by crop cultivation, forest plantation, or pisciculture. As a result of these changes, along with the increasing pollution and eutrophication of the waters of the Danube, and decades of exploitation and poor fishing regulations, the fish population has been visibly reduced.
In 1991, the Romanian part of the Danube Delta became part of UNESCO’s list of World Heritage Sites. Around 2,733 km2 of the delta are strictly protected areas.
As a young region in full process of consolidation, the Danube Delta represents a very favorable place for the development of highly diverse flora and fauna. Situated on major migratory routes, and providing adequate conditions for nesting and hatching, the Danube Delta is a magnet for birds from six major eco-regions of the world, including the Mongolian, Arctic and Siberian. There are over 320 species of birds found in the delta during summer,of which 166 are hatching species and 159 are migratory. Over one million individual birds (swans, wild ducks, coots, etc.) winter here.
