Milicz Ponds, Lower Silesia, Poland
The Barycz River swampy valley was chosen for the complex of fish ponds built in the 13th/14th centuries. Today the ponds serve as the habitat for many species of water and mud birds. Some of them, together with their environs, have been turned into an ornithological reserve and a landscape park known as the Barycz Valley. One of Europe’s largest wildlife reserves, it offers to bird watchers a great number of observation points situated on dikes.
