In the space of a year, the wolf population has grown in Switzerland. The latest estimates from the Swiss Wolf group show at least seven packs living on the territory during the biological year, against four the previous year.
A biological year runs from the beginning of May to the end of April. By counting on a minimum of seven packs, there are now some 60 to 70 wolves in Switzerland, writes the Swiss Wolf group in a statement published on its website overnight from Saturday to Sunday.
The packs live in the cantons of Graubünden (Surselva, Obersaxen, Beverin), Valais (Val d’Anniviers, Val d’Entremont, Chablais) and Vaud (Col du Marchairuz). Solitary individuals are also present in the Bernese Oberland and in central Switzerland.
In total, the number of packs could go up to nine, specifies the organization. The status of two groups, one in the Calanda massif in Graubünden, the other in the Ticino Valle Morobbia, remains unclear.
Seven reproductions are also confirmed, according to the press release; three in Valais and three in Graubünden, and one in the canton of Vaud. A pack has at least three individuals, male and female, living in groups on the same territory.
