I love your website! I have browsed through many of the selections that you have on tree data. I have a strong background in forestry and recently while doing work with an organization called MNFI, I found a large tree that I wanted to show to you'all. Its a picture of an eastern cottonwood, by far, the biggest tree I have seen of this species, also known as populus deltoides. It was growing in far southern Michigan, on alluvial soils, within 15 feet of the raisin river. Take a look at the photo below.
Anyway, there is very little trunk taper from the base to the top. It would have taken about 5 or 6 people probably to stretch arms and touch around it. I realize that it is a double tree, but the split comes above breast height DBH. Its probably about 90 feet tall, and the trees leaf area, or the amoun of total tree volume is very high. I did not take time to determine circumference, or height.. I believe that it is the biggest cottonwood in this county for sure, and maybe in all of southern Michigan? Show it to your guys and see if they are interested in measuring. I can GPS the site for you, so that it is easy to get to.
I hope you guys like this, and hope that you are interested in looking at closer. Its truly a huge tree for this specimen! I hope to hear back from you.
