This isn't relevant for much of the USA. However, for the Adirondacks, Northern VT, NH ME, the UP in Michigan, etc.... Around here winters can be SEVERE and winter kill is a huge problem some years. Food plots and the usual stuff doesn't do much for your herd when its end of Feb or Mar, the deer are on the ragged edge of survival and you get another 24 inch snowfall.
I've convinced theist single thing I can do is selective cutting of some mature trees. Simply walk out into the woods where trees are becoming mature, and cover is thin, find a couple Poplar or cedar trees, and hinge cut them. I achieve three or more objectives.... 1) I have provided an all- natural supplemental feed that, unlike corn or hay, doesn't interrupt natural gut flora. I'm simply taking food they already eat, but cannot reach, and bringing it down to deer level. These trees will be STRIPPED in 24 hours. 2) I'm letting light down to the forest floor where I can start the forest cycle again. More young food next summer 3)the hinge cutting creates cover and bedding area
No tractor. No plow. No tiller. No fertilizer, lime or seed. Slap the snowshoes on, grab the small chainsaw and take a walk in the woods. In and done in 30 minutes. Repeat next week....
