August 19, 2026 – Three new wolf packs were confirmed in the Swiss canton of Grisons, or Graubünden, in the first half of August, the canton’s hunting and fisheries office said.
In the Lower Engadine area in the east of the canton, wildlife officers confirmed through observations the formation of a new pack with at least three wolf pups, named the Giarsinom pack, as well as another with at least five pups, named the Madlain pack, the office said on Aug. 19.
In the Heinzenberg region in central Grisons, wildlife officers confirmed two pups using camera traps and subsequent observations, the office said.
Grisons is Switzerland’s largest and easternmost canton, and had 12 wolf packs within its borders as of the latest count, data from the hunting and fisheries office shows. A further two cross-border packs have part of their territory in the canton, including the Madlain pack, according to the office.
After being eradicated from the country, the wolf (Canis lupus) started recolonising Switzerland in 1996, and almost all Swiss wolves originate from the Italian and Alpine populations, according to the KORA Carnivore Ecology and Wildlife Management foundation. The first pack was established in 2012 in the Calanda area between the cantons of Grisons and St. Gallen.
Switzerland had 43 wolf packs at the end of January 2026, including 32 with their territory entirely in the country and another 11 that also occupied territories in neighbouring countries, according to KORA. The organisation defines a pack as at least three wolves observed together, or a sexually mature female wolf with confirmed reproduction.
