I was given access to a friends 200 acres of land that was logged last year. Tree tops all over the place and a bunch of nice logs left that the logger didn't want. There's enough wood there to last me 3 lifetimes. Mostly ash, walnut and poplar. I can only cut there between January and April though (hunting and planting etc in between). My question is how long do you thing these tops will last before they start to decay where they won't be worth messing with?
