Red Maple
Red Oak
Ash
Box Elder occasionally, have some Shagbark Hickory but I haven't cut that section of the property yet.
Try to cut about 2/3rds Red Maple, 1/3rd everything else as part of long-term woodlot improvement -- take out the garbage to give the red oaks and other top notch hardwoods more space.
I also try to leave the Ash. I don't have that many, and while they'll eventually probably get ash yellows or even more eventually Emerald Ash Borers...I figure I let them mature as much as possible. (Plus they're nice as emergency wood).
I have a few Beeches, White Oak, Sugar Maples...those I also try to avoid just because I only have a few and like to try and keep the woods diverse.
