damage to acer palmatum from fallen oak
My mature Japanese maple was in the path of a fallen white oak. A major stem is cracked horizontally but with little bark damage. Should I support it with a wire to a sound limb and hope for the best? If pruned away it will leave a gap in the structure of the tree.

If you could attach a photo of the crack we could give you a more helpful answer.
It is possible for a branch to have a crack and have little effect, but we'd have to see how it cracked and the extent.
Because this crack goes along the branch longitudinally, it does not cut across the lines that transport water and nutrients up and down the branch So, the branch should survive.
However, the break will weaken the structure of the branch. It may need support. There are ways to support the branch from below or above, and there are ideas online but we can't really address them. You may want to contact an arborist familiar with those techniques, as future growth of the tree must be taken into account. To find an arborist near you certified by the International Society of Arboriculture, follow the prompts on their website: www.treesaregood.org
You'll still need to narrow it down to arborists trained in this kind of work.
