Caribou encounters with wolves increase near roads and trails: a time-to-event approach

Posted on October 27, 2020

Caribou and reindeer Rangifer tarandus are declining across North America and Scandinavia in part from wolf Canis lupus-mediated apparent competition with more abundant ungulate prey species. While caribou generally persist in areas with low wolf density, wolf packs that overlap … read more

Wisconsin’s gray wolves are in serious troublebit.ly/3ANeaeFThe aim of the Wisconsin Department of Natural Resources was to have a hunting season that “resulted in no annual increase or decrease in the state’s wolf population.” Wolf hunts are annual events where hunters congregate to hunt the animals for sport, though this practice has become controversial in many countries. However, that no change in the wolf’s population goal was not met, says Adrian Treves, an ecologist at the University of Wisconsin-Madison and coauthor of the new findings.“The population decline was enormous relative to other wolf-hunting seasons around the world,” he says. “We’re alerting our state government that the population is more vulnerable than they seem to understand.”The legal hunt permitted new methods such as pursuing wolves at night, by snowmobile, or with groups of hounds. “Hunters using these unprecedented methods can wipe out a population in short order if not carefully supervised and regulated,” he says. “Put all together, it was sort of a perfect storm of wolf killing.”If poachers are also using these methods, Treves says, “We could be in a darker place for the wolf population in the state.” Another concern is that the hunt took place during the wolves’ mating season, so it’s unclear how many packs managed to reproduce this year. Treves and his colleagues are now evaluating how many pups might have been born to wolf packs that survived the hunt and what the state of the population might be come November, when Wisconsin currently plans to hold another hunt. He and his team recommend that the state hold off on more wolf hunts until data can be collected on how severely the recent hunt disrupted the mating season and until the population has had a year or two to recover. ...
