Lots to consider for sure. This is my 12th spring working that area and was by far the lowest number of bear sitings.
Nube- your theory on snow, den sites, and mortality sounds valid. There was not a lot of snow until late this winter. Years ago, I helped with the bear study in the Conklin area. It amazed me where some of those bears would den up. A couple were simply dug in JUST under the moss, in the middle of a muskeg, with not a tree in sight.
