Hello, We have a tree in our yard that is being damaged by something. Can you give me an idea of what it might be? I originally thought maybe deer were cleaning their horns in it but there is now a type of sawdust in there and the damage seems to be progressing pretty rapidly. Thank you Shelley Kuriata

I can't be sure what is going on with your tree. Is it possible this tree was struck by lightning? A lightning strike provides a portal for damaging insects and fungal diseases. The tree is dead in the areas above where the bark is gone. It is questionable if this tree will survive.
Your best resource for diagnosing and treating your tree is to consult a certified arborist. An arborist is a certified and generally insured expert in trees and their problems. He or she can examine your tree and make recommendations regarding the health of the tree, any needed judicial pruning, and whether or not (in his opinion) it should be removed. You can find a certified arborist in your area here:
Click on "Find an Arborist" at the top of the page; then click on United States from the pull-down menu. Then enter your State and City. This should bring up a list of certified arborists nearest to you. Or you may be able to locate one under "Tree Services" in your local Yellow Pages.
