Since wolves returned to Germany 20 years ago, they have spread quickly in many parts of the country. The rapid increase was due to high survival and reproduction rates in areas with favorable environmental conditions. These findings are the result of an analysis carried out by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in collaboration with the LUPUS Institute, the Federal Agency for Nature Conservation (BfN), and the Senckenberg Center for Wildlife Genetics.
