Canadian and European beaver
Castor fiber, Castor canadiensis
In Finland we have both Canadian and European beavers. Although the native European species was hunted to extinction in the 19th century, in 1935 some specimens were re-introduced from Norway, and since then the population has grown to such numbers that around 250 European beavers can be hunted yearly. Canadian beaver was introduced to Finland in the early 20th century and nowadays hunting is only regulated by hunting seasons.
