I'm in southeast Missouri. We have thousands of acres of hardwood forest around here that gets little to no management, and the oaks seem to be doing just fine. It may be different where you are though, but not here. The loggers are harder on the hardwood forest than anything else. But where there is national or state forest land, the oaks are doing fine.I don't know what state you're in but here in central illinois if there's no management the oak forest will cease to exist in the future. We've got honeysuckle shading out any seedlings that the deer don't eat. Or you've got open floor heavy canopy areas and the deer easily find any oaks that sprout and again eat them up. In these scenarios some intervention is necessary to perpetuate a hardwood forest. Otherwise you'll leave behind a woodland bound to be overrun with locust, elm, Hackberry and other less desirable trees in the future.
I'm hoping that now I'm retiring to have time to reintroduce fire to my small woodland. I'll have to kill honeysuckle and autumn olive first. That will improve the browse substantially.
This part of the country was once home to the biggest sawmill in the world, and they spent over 30 years logging out all the giant white pine that once dominated the landscape. Once the pine where gone, oak grew abundantly and took over. Now over 100 years later, the oak is well established.
Other than oak dominate forest land, we have pasture ground. Around here, good hunting greatly depends on a healthy and plentiful acorn crop. If not, we are stuck hunting the edges of pastures. Planting a good clover patch is a great way to attract deer especially if there is a weak acorn crop.
I have nothing against land management, and it is necessary in some places just to compete with the neighbors. I think planting different varieties of food plots and fruit trees are a good way to supplement the deer's diet.
One thing I often do is anytime I am out and about and find some nice acorns from different varieties of oaks, I grab a couple handfuls of those acorns and take them with me and plant them in other areas I go to. I do other trees as well. Maybe 75 years from now after I am dead and gone, there might be some young bow hunter who will be sitting by one of those trees I planted and kill a deer.
