Zasavica
Serbia
The Zasavica (Serbian Cyrillic) is a bog in the region of Mačva, west central Serbia. It is a major wildlife refuge and one of the last authentically preserved wetlands in Serbia. In the 2000s it became a popular attraction with the successful reintroduction of beavers, which had become extinct on the same land areas 100 years before.
