Overview
- BIJ12’s 2025 monitoring found 131 genetically identified wolves in the Netherlands, including 79 detected for the first time, and it estimates about 14 packs nationwide.
- DNA confirmed a new pack on the border of the Gelderse Vallei and the Northwest Veluwe with three pups, raising Gelderland’s total to nine packs.
- Across the country, 29 wolves died in 2025, with 65.5% of the deaths in Gelderland, and most were caused by road collisions with some from fights between wolves.
- On the Utrechtse Heuvelrug, monitors documented at least six wolves at the end of 2025, and a GPS-collared male appeared after authorities shot a designated problem wolf.
- Utrecht logged at least 109 wolf attacks on farm animals in 2025 that killed more than 300 sheep and goats, and one case involved a wolf clearing a fence that met official standards.
