I've spent a lot of time this fall in the U.P. and the winter we had last year seems to have resulted in a low fawn survival rate. It was the same last year too. According the the Deer Camp Survey, 2018s fawn rate in Nov. was about .51 fawns per doe. After mild winters its over .6 and when the winter is extremely severe, it dips to .4 fawns per doe. Law fawn numbers equate to low yearling deer numbers the next year, so following two moderate to severe winters in a row, one can expect fewer yearling deer in the herd. We have only had one mild winter since 2012 (2016), so the only real strong year class is from 2016, which are now three year old deer now. Of course in areas dominated by big woods the impacts of winters are more pronounced and less so in farm country or areas where winter feeding elevates winter stress. In my area, our fawn rates are usually lower than average. The good news though is that I've found very few winter killed deer, so it appears that carry over of deer was good.
