'Field of Livno'), located in Bosnia and Herzegovina, is the largest polje (karstic field) in the world and a RAMSAR wetland site.

A typical example of karst polje encircled by tall peaks and mountain ranges, the field is characterized by many unique natural phenomenons and karstic features.

The largest villages on the field are Guber, Grborezi, Podhum, Prolog, Čuklić, Zabrišće, Bila, Čelebić, Lusnić, Strupnić, Kovačić, Vrbica and Bojmunte.

The most important of these are the Žabljak, the Sturba, the Bistrica, the Brina, the Plovuča, the Jaruga and the Ričina which are all rich in trout and crab.

Additional projects are in planning which could seriously compromise the delicate hydrological balance of the Dinaric karst, which is crisscrossed by underground rivers.
