Hunters asked not to shoot ear-tagged and radio-collared research bears
The Minnesota bear hunting season opens Saturday, Sept. 1, and the DNR is asking hunters to avoid shooting marked research bears. These bears are marked with distinctively large, colorful ear tags and have radio collars.
Researchers with the DNR are monitoring about 30 radio collared black bears across the state, especially in zones 27, 25 and 45, and in parts of the no-quota zone. Most of them are in or near the Chippewa National Forest between Grand Rapids and Bigfork.
Others are farther north, near Orr or Voyageurs National Park. Some collared bears are also around Camp Ripley, and in northwestern Minnesota, especially near Thief Lake Wildlife Management Area and Plummer.
“We’re asking hunters to watch out for these valuable research bears, and avoid shooting them. These collared bears are providing much of the data that is being used in bear management,” said Dave Garshelis, DNR bear research scientist.
A key to the research is looking at year-to-year changes in natural food supplies and how that affects individual bears in terms of their habitat use, physical condition, denning, reproduction and interactions with people. This research is not designed to evaluate mortality from hunting. Trapping new bears every year to replace the ones killed cannot substitute for long-term data on individuals, added Garshelis.
Most of the collars have GPS units. The GPS coordinates are either uploaded to a satellite, or stored in the collar and downloaded by DNR researchers when they visit the bears in their dens. Each bear provides several thousand data points per year.
The bear’s coat often hides the collar, especially in the fall. And most of the collars are black. But all collared bears have large (3 by 2 inch), colorful ear tags so hunters can simply identify a collared animal by these large tags, whether or not a collar is visible. The tags should be plainly visible when a bear is at a bait, or on trail cam photos.
Photos of collared research bears and some research findings gained from them are available on the DNR website at mndnr.gov/bear.
DNR officials recognize that a hunter may not be able to see a radio collar or ear tags in some situations. For this reason, taking a bear with a radio collar is legal; however, waiting a few minutes to get a clear view of the bear’s head would reveal whether it has large ear tags, which indicates that it is collared. Bears with small ear tags (1 by 1/4 inch) are not collared but are important for other ongoing research projects. It is okay to take a bear with these small ear tags; if you do, report it as you would with any collared bear.
Any hunters who do shoot a collared bear should bring the collar to a bear registration station and call the DNR Wildlife Research Office in Grand Rapids at 218-328-8874 or 218-328-8879 to report shooting a collared bear.
Also, most collared bears have a small implanted heart monitor under the skin on the left chest. This contains valuable information stored in memory. Hunters who find this device while skinning the bear should leave it with the collar. Hunters with trail cam photos of ear tagged bears are asked to email the photos, and locational information to firstname.lastname@example.org.
