I finally ID'ed the crud trees on my property. I've got tall pines and Stag Horn Sumac Trees. Ice took down a sumac and I cut and split it, but someone with more experience then me, said I might as well throw it all back into the woods. It's only a hour of my time wasted - so it's no big deal, but isn't all wood burnable if you make sure it's dry? He said it provides no BTU's and just smokes - it's a waste - trash wood. I looked at 2 lists rating firewood and this species of trash wood is not even on any of the lists - perhaps that should be a clue to me. I am sure he knows best. Should I throw it back into the woods or burn it next fall - mixing it in with better quality wood - just to used it ? He also helped me to ID the other wood I got - Cherry! Man I suck at tree identification! I am going back to the site tomorrow and hope to get all that's left (maybe 3 truck loads of hardwoods). Just wanted to say this site is awesome and I can't begin to say thanks to all of you for helping me shorten the learning process.
