Definitley hire a forester, and do not use one the logger supplies. It's all a matter of who the forester is working for. The forester will ask what your goals are, mention all your goals, not just maple. Then the logger will mark the trees and solicit bids. The forester will supervise the entire process. While you will pay for the forester, it will be money well spent, and the logging will be done right. Sometimes it may cost you less than not hiring a forester, because you won't have to fix things done wrong. There are different methods of paying the forester. I prefer paying by the hour rather than a % of the logging contract. I feel that this method keeps the forester better focused on your goals.
A forester will likely have you remove all harvestable Ash (since they will soon die) but will likely not remove all other non maples. Mono culture invites too many pests that are not good for the maples. Also, as mentioned above, the cut will not thin the maples too radically, opening not more than 2 sides, then opening the other 2 on the next logging cycle, in 5-10 years.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
