Sažetak
Since the end of beaver reintroduction in Croatia in 1998, continuous monitoring of the expansion and distribution was made. With the release of 56 beavers into the Sava river basin, the initial population has been formed, and it immediately began to expand. During the first few years, the dynamical expansion took place. In the first 2 or 3 years beavers colonized remote sites within the range of more than 100km. On some sites only one family was registered. The distances between families were from 3 to 130 km. In the next period, the number of the beaver families continued to grow which diminished the distances between them and led to a better use of the habitat. During the last 10 years, the upper parts of the streams were filled practically to their full capacity. The results of the research showed that larger stream flows were less populated than the smaller ones. At present, in the most populated areas, there is one beaver family on every 2, 4km. According to our research the number of the beaver families doubles every 4 years.
