A friend who was moving had a 10 year twin trunked oak tree that was not thriving. It was between 2 large sycamore trees. I offered to give it a new home in my garden. It was transplanted in Oct 2006. Unfortunately only one of the trunks grew new leaves this season. The other does not have a single green leaf.

Is the bare trunk dead or could it still recover next year.

Follow the handy tips listed there. If nothing leaflike appears on the bare trunk next spring, I think you should remove that trunk. I don't think twin trunks on oak trees look particularly well anyway, so it may be for the better.
