Restitution of the beaver in PNP

In the Poleski National Park the restitution of the beaver was commenced at the beginning of the 1990s by bringing in a dozen or so individuals from the Suwalki Region - mainly from the Goldap Forestry Management. In October 1992, the animals were let out to the three lakes within the borders of the park. Thirteen specimens found the new place of living at that time: 7 males and 6 females, out of which 3 females were adult, and the age of the remaining ones ranged from 6 months to 2.5 year. They were divided to four families. Since then a steady increase of the size of the population has been observed and 15 years after beavers were introduced, their state is high. At the turn of December and February every year, stocktaking of beavers preying places is conducted with the Djakov method, and the results from stocktaking are presented on the following graph.
