600 to 700 beavers live in the Dachau district. In the past 20 years, the population has almost tripled.

By damming and felling trees, the beaver creates standing water and clearings near the shore. The beaver is also "a valuable ally" when it comes to reclaiming the moors, as Roderich Zauscher explains. But the beavers also cause trouble, the environmental expert admits. Especially in agriculture and in the forest, especially when it jams. Farmers can then no longer use the area as usual. "Then it undermines streets and paths," says Sabine Schöttl, head of the Lower Nature Conservation Authority. 'Beavers are not just another mammal, they are an "incredibly valuable landscape designer" and a "loyal friend and helper,' says Barbara Karcher, a beaver consultant in the district office. The rodent is also a great benefit for the water balance of the area.
