If the trees are oaks, walnuts, etc and decent size (greater than 10" diameter) why not have them cut into lumber? I have about 2500 to 3000 BF in the area that I will be clearing for a pond later this summer and that is my plan. Local sawer is charging me $0.25/bf to cut it for me. I plan on making wood flooring for the future house out of it and maybe other things. I am assuming that I will still have a decent burn pile left after this but that will get burn in the winter.
