European beaver (Castor fiber L.) is semi–aquatic species belonging to the genus of rodents (Rodentia) which was once widespread in the entire surface of northern hemisphere of the Earth. With time they almost completely dissapeared from natural area of distribution because of various reasons and the biggest reason was human. Beaver dissapeared from Croatia in 1897. Restoring beavers in Croatia began in the early nineties of the twentieth century. First beavers were reintroduced in april 1996 and the last one in march 1998. Total number of beavers who were reintroduced is 85 individuals, 44 males and 41 female. Most individuals is reintroduced to the area Turopolje and Lonjsko polje. After 1998, with every year there were more and more beavers. In the end of 2011 in Croatia were 400 family of beavers and more than 1000 individuals that have taken almost all aqatic ecosystems of the central Croatia and they begun spreading to the neighboring countries: Bosnia and Herzegovina, Hungary, Slovenia and Austria. In the view of increasing the number of beavers can be concluded that the proces of reintroduction of beavers was successful because habitats have been favorable for their progression and further population growth.
