Do cows eat gum trees? Fire is a quick and effective method of mgmt. And, it's something a land mgr could do on a large scale. If there is enough farming acreage, you could really turn up the tonnage of food produced by improving those acres to produce much forage for the deer. On a large scale (and not that large), I just don't think you can make a difference in a given piece of land like you're talking about CNC. I suppose a lot of things are possible... physically speaking... but all things cost money and time and usually one or the other runs out!!

Oh man at the new herbaceous growth after a fire (given temp is right) and fertilizing your natural growth makes a difference. Any given acre of land could have an enormous turn-around in a matter of a few days with fire. That given acre could be thousands of acres which could be improved QUICKLY!!!!!! At not a lot of costs to the landowner.

I vote for fire.
