Just the bear facts

This week’s column is bought to you, thanks to a bear research study that has been conducted for the last 30 years in Ashland, is run by Tim Ginnett who is an associate professor at the College of Natural Resources at Stevens Point.

High 25, Low Minus-14

Once again there is way more to say than I have space to put it, so I will be to the point so that I can cover as much as possible.

I met Margaret ”Maggie” Heino back in the early ‘90s when professor Ray Anderson was running a way to get elk introduced into Wisconsin. All it took was one call to my friend Maggie, who is the chief logistics person for this operation, and I was back in the bear dens.

south of Mellen, and she was discovered on private land by Jake Baldaf while deer hunting last fall. where the den was being created, which was dug into the ground at a somewhat horizontal angle over 8-feet deep.

Once the snow fell, Jake hiked into this stand of balsam trees and rechecked the den which, with an entrance width of 28 inches, was covered for the most part with deep snow. The tell-tale sign that there was a bear inside was a “blow hole” where the sow’s breathing (and possibly the cubs’) was keeping a small entrance from completely being snowed over.

Today, I hiked in with several volunteers on this study, some members of the Baldaf family and Tim.

The one mistake that I made was having forgotten my snowshoes in my living room and it to the den.

First, everyone is very quiet and listen. Next, the sound of cubs is heard. Next, a volunteer does the job of shoveling out the den entrance so Bruce Prentice, who is a retired Ashland teacher, is held by his feet or jacket as he assesses the situation.

Though there are very few volunteers consumed by sleeping bears, the job of assessing the den by looking into it and being within inches of a bears face, takes a brave man or woman.

Next, the bear’s weight is estimated and she is anesthetized which lasts for about 90 minutes. First the cubs, who were born about Jan. 1, are pulled from the den and each one is given to a landowner or volunteer and put into their jacket to keep it warm.

There were four cubs with this 7-9-year-old sow, and it is believed that she had four cubs two years ago as well. Each cub was weighed (about 7 pounds each) and sexed, and their hair was measured. Three of the cubs were males and one was a female.

Next, the very large job of removing the female from the den was done. Four strong men did this task and it was not easy. The sow was weighed and she came in at 255 pounds which is a very nice size for a sow this late in the winter.

Interesting fact! The sow had dug her den 100 feet from a wet- spring arrives and have green grass.

When the sow wakes up she will be a vegetarian and will do short trips to the wetland alone to feed and drink. Next, she will bring the cubs for short trips, then the den will be abandoned.

I watched as this crew of six - suring the sow, taking her temperature, and putting on her radio collar which Maggie will use through telemetry to record her movements

I learned that nature does not decide until November when the sow enters her den if she is in good enough shape to give birth to cubs or absorb them.

I learned that males are seldom radio-collared due to their nomadic lifestyles. It would be leave the den (a female has a much smaller home range).

I realized after meeting the Baldafs, hearing Jake’s story and then talking with Tim just how important it is if you know of an active bear den on your land to inform the right people and give access so that this type of research can have its opening phase.

Wisconsin’s bear population is growing, as is the black bears’ range across the state. One way to get an idea as to the health of our bears, as well as their numbers, is through telemetry and den studies.

When the den was closed it was done so by putting balsam boughs over the entrance and then a bit of tobacco was thrown over it to

Love my job!
