Laws pertaining to trees are different in each state. Take this as an opportunity to become aquatinted with your local laws. But again, call in knowledgeable help. Don't depend on a friends advice unless they are a lawyer. Firewood is needed.
People do take trees down for firewood.
But taking down a valuable tree for firewood is not helping you in the long run. Trees add to property value. However, if you own lots of acreage you might find a snag of a tree to cut down. Leave the good trees alone.
