First my apologies for not replying to your report sooner. We have been working out some bugs in the reporting hotline which has delayed our response time.
Thanks for your report of tree of heaven. Yes, this is a very weedy invader which has become more and more abundant in the recent years. It is actually fairly widespread across the entire United States but only listed as noxious or prohibited by four states in New England. I would definitely encourage you to control it on your property. Here are a few good websites that outline some of the biology and control.
