Beech is one of my favorite firewood here up north. I did a timber survey with a forester recently and learned that the bumps on many of the local beech trees is a symptom of the beech bark disease which came to NA in the 1970's. Many of our local beech trees have a bark with many bumps on them - and no cure, but there are some beech trees which have a resistance to this disease - which eventually weakens the tree but makes the wood not usable for lumber. Trees which are resistant should be considered to let grow as the roots from the main tree spread with other suckers which is one way beech trees reproduce. Most of the larger beech trees also have linear scratches on the bark - which are from bear claws as the bears climb to get to the beech nuts. In years with good mast crops the deer also thrive on beech nuts on the ground. So consider what beech trees provide for your local ecosystem and can provide lumber or firewood for us - they become a valuable resource to enjoy!
