Coyote populations across the United States are influenced by a number of factors, but surprisingly their abundance is found to be higher in areas that allow hunting of the predator, according to research by a University of Utah wildlife biologist and colleagues in other states.

As U.S. landscapes became increasingly plowed and paved over the past couple centuries, wildlife has become less abundant thanks to the loss and fragmentation of habitat. But not coyotes, North America’s most successful mid-sized predator, which have expanded their range despite eradication campaigns and rapid urbanization.

Coyotes are bold generalists, eating anything from seeds, trash, roadkill, rodents, deer fawn, even pets, and fill niches left vacant by the elimination of bears, wolves and cougars, according to co-author Austin Green, a researcher with the U’s Science Research Initiative and former graduate student in the School of Biological Sciences.

It is reasonable to expect hunting to reduce species abundance, especially in conjunction with other anthropogenic factors that spurred the wave of Holocene extinctions. Unregulated hunting, after all, resulted in the disappearance of the passenger pigeon, dodo and monk seal, and near-extinctions of many other now-rare species, including iconic megafauna such as the American bison and white rhinoceros.

Coyotes, on the other hand, have displayed a pronounced resiliency in regions, such as Utah where hunting and trapping these predators is heavily subsidized and barely regulated, according to the findings based on extensive camera surveys.

“This is corroborating a lot of other evidence that direct hunting and intervention is actually not a really good way to manage coyote populations, if the goal is to decrease their abundance,” Green said.

The new study, which was funded in part by the U’s Global Change and Sustainability Center, was led by the University of New Hampshire (UNH). It relied on data compiled by Snapshot USA, a sprawling collaborative campaign to sample wild mammal populations with motion-triggered trap cameras arrayed in transects each fall.
