Within the space of a year, the wolf population has grown in Switzerland. According to the latest estimates of the Swiss Wolf Group released on Sunday, at least seven wolf packs live in the country compared to four in the previous year. A pack is defined as a territorial wolf population of three or more socialised animals of both sexes.

The updated figures are from the biological year that runs from the beginning of May 2019 to the end of April 2020. Assuming a minimum of seven wolf packs, it is estimated that there are now between 60 to 70 wolves in Switzerland.
