It was not only in Denmark that the beavers were pursued – it is estimated that the total European beaver population was down to about 700 individuals around 100 years ago.
Reintroduction of the beaver
In 1871 the species was declared eradicated in Sweden. Since then big efforts have been made to revitalize beaver populations through a change in management combined with reintroductions. For example in Sweden, where 80 Norwegian beavers were released in the period from 1922 to 1939, which has now led to a Swedish population of around 100.000 animals.
The 18 beavers released in Klosterheden came from Germany, and the population is closely monitored with annual counts in April conducted in cooperation with a high number of volunteer observers. Based on these counts it is estimated that the West Jutland beaver population has grown to more than 200 individuals, and they have spread to other river systems such as the Skjern Å. In 2009 to 2011 additional 23 beavers were reintroduced in North Zealand, and they are reported to be doing fine.
