I heard about a guy at work who is having a tree taken down so I shot him an email asking if he had plans for the wood. His reply was "I am not sure if you will want it. The tree is full of insects eating it.. That's why I am having it taken down." I had never considered that there would be a case where a tree being taken down might not be worth burning. Thoughts? are there bugs that could make a tree not worth adding to the wood pile? Are there things that can be done to mitigate this sort of situation?
