To respond to a few of you that have said this is normal and we have die offs every so often is partially correct. What is not so normal anymore is the lack of winter cover for any animals just not deer and pheasants. Almost all tree rows have been ripped out, no crp, no section lines and since we had a fairly dry fall most of the slew bottoms were either cut, plowed or burned. So if you take in account the lack of winter cover a normal ND winter is a deadly winter for our wildlife now a days. Not trying to be gloom and doom but if you were to drive around in the country of the north central to NW part of the state you soon would ask yourself how in the hell would anything survive 3 months with nothing.
Those things provide absolutely no cover and do almost no good in conditions like these. They need heavy thermal cover, ie. large tree plantings at least 11 rows thick.
