UrduA new study shows that wolves in Washington state are not having much of an impact on white-tailed deer, one of their primary prey.

Cougars were second in their impact. Wolves were a distant third.

Hunting, hidden deaths led to estimated 30% reduction in Wisconsin’s wolf population
About 100 additional wolves died over the winter in Wisconsin as a result of the delisting of grey wolves under the Endangered Species Act, alongside the 218 wolves killed by licensed hunters during Wisconsin’s first public wolf hunt, according to new research. A majority of these additional, uncounted deaths are due to “cryptic poaching,” where poachers hide evidence of illegal killings.
Weakened protections led to more disappearances of endangered Mexican wolves
