Dr Tim is right. I have an Infrared map of my property. It was included in my forest Stewardship plan. The local State forester worked with me to develope the plan and it included an infrared map. Check the state forester who handles your area. He may have such maps. When you get it the reds are evergreens and they will show well, the hardwoods will not show any idea what species they are. I would ask around and drive the roads. Get to know sugar maples from a distance. I can usually spot a sugar woods from a fair distance but then you will need to do the leg work to get a feel for how good it might be. If you check after leave turn in the fall you will see better but then you have far less time to make the arrangements. Try an ad in your local paper or pennysaver. You just might find one.
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.
