A example of how coyote control can benefit deer is what happened on the Gaspe Peninsula in Quebec, just north of the Maine border. In 1986, had a healthy herd of about 15,000 whitetails, and a low coyote population.
However, after several consecutive harsh winters — and extensive clear-cutting that eliminated traditional yarding areas — coyotes got the upper hand and wreaked havoc on the deer population.
By 1991, researchers estimated that only 500 deer remained on the peninsula. To save the herd, the province banned deer hunting, implemented strict logging regulations and implemented an aggressive coyote snaring program.
According to Noonan, 80 trappers were trained to snare coyotes, and they were instructed to focus their efforts on 80 percent of the remaining deer yards.
The plan worked. In just three years, the trappers caught 1,500 coyotes. Deer numbers rebounded, and by 1999, the peninsula had a population of more than 2,000 whitetails.
However, the coyote problem didn’t end there. When the snaring program was stopped for two years, the coyote population rebounded, and the deer population again decreased.
As a result, the peninsula instituted a subsidized trapping program that is still used today.
