Hello,   I have  a Tulip Poplar tree about 24 inches in diameter and possibly 80 feet tall.  The lower sections of SW side of the tree have lost huge amounts of bark. There appears to be bark under it, but I can not tell if this is good bark or not. We have lived in our home for 15 years and this has never happened before. I do not see any insects and it is showing nomral signs for a spring bloom.   I estimate enough bark has fallen off in chuncks to fill 4-5 five gallon buckets. The chuncks range in size from peanut to baseball size diameter. The tree does not appears to have any dead branches or other spots out of ordinary. We have 2 other puplar trees of this same approximate size about 50 feet away and they have not had this issue.

Is this something to worry about?   I could not attach a picture to this website. 

Thank you, Owen
