Each month, we highlight research MDC uses to improve fish, forest, and wildlife management.

Assessing Species Distribution

Spotted Skunks and Gray Foxes

“Spotted skunks and gray foxes can be difficult to find,” said Hannah Warner, a graduate research assistant with the University of Missouri School of Natural Resources. She leads the field work for a study currently underway in Missouri’s Ozark region. “But,” she said, “with the right kind of bait, like sardines or a predator lure, you might get lucky and capture one on your trail camera.”

The study started in 2020, after the U.S. Fish and Wildlife Service (USFWS) received a petition to add the plains spotted skunk and the prairie gray fox to the endangered species list in 2012.

“This study will provide additional and more up-to-date information on the status of both species, which will help inform listing and management decisions,” Warner said.

Warner’s team is using game cameras to detect spotted skunks and gray foxes, as well as other mesocarnivores, including raccoons, opossums, coyotes, and bobcats. Mesocarnivores mostly eat meat, but they also forage for fungi, fruits, and other plant material.

Warner’s team also evaluated the habitat surrounding each game camera. They measured area size and composition, canopy cover and species of trees, as well as available denning cover. “These measurements will help us better understand the species’ relationship to habitat at different spatial scales, which could help us identify distribution patterns,” Warner said.

In addition to providing current information for USFWS use, it will help MDC furbearer staff develop protocols to monitor species distribution and status, as well as habitat management effects on spotted skunks, gray foxes, and other mesocarnivores in the Missouri Ozarks.
