Young wolf killed by vehicle in central Switzerland's growing wildlife conflict

A young wolf has died after being struck by a vehicle in central Switzerland. The animal, known as M633, was discovered on a road in Euthal, Schwyz, on November 2. Authorities confirmed the collision caused its death at just two to three years old.

The wolf first appeared on records in September 2025. Genetic testing linked it to attacks on two sheep near Trachslau. Later, the same evidence tied M633 to another wildlife incident in Alpthal.

An examination revealed no gunshot wounds on the animal's body. Its death adds to the ongoing monitoring of Switzerland's wolf population. As of early 2026, four packs are officially recognized: Surselva and Calanda in Grisons, Nufenen on the Grisons-Valais border, and Jura in the northwest.

M633 was not part of an established pack but roamed independently. Its movements were tracked through DNA samples collected at attack sites.

The wolf's death highlights the risks wildlife face near roads. With four packs now active, Swiss authorities continue tracking these animals. Genetic testing remains key to identifying individuals and their involvement in livestock attacks.
