In Serbia, beavers were mostly extinct by the 1870s, with the last specimens being seen around 1900–1902. In 2004, 31 beavers were reintroduced in the Zasavica reserve by the Biology Faculty of the Belgrade University in collaboration with the Bavarian Science Society, and 45 beavers were released in the Obedska bara reserve.

Beavers make their way through the city by traversing the city's waterways. The city of Toronto government, and the Toronto and Region Conservation Authority (TRCA) do not keep track of the number of beavers residing in Toronto, [81] although an estimate from 2001 places the local beaver population at several hundred.
