We have an old burr oak (maybe 200 years old) that suffered serious damage in a wind storm about 2 weeks ago. A major branch (about 2 feet in diameter) was stripped from the tree leaving a scar about 10 feet high and 3 feet across. There was no root damage and about two thirds of the main trunk (which is about 3.5 feet in diameter) is still in tact. There is some rot in the core of the trunk (about 1 foot in diameter). We have been getting mixed messages about what, if anything, we should do. It was (and still is) a beautiful tree and we would hate to lose it. Any advice would be greatly appreciated.
