We have just purchased a new home and are trying to ID some of the small trees that seem to have "planted themselves" and were left to grow by the former owner. We've checked out several tree ID books, but we can not seem to figure out what this particular one is. The more mature ones have reddish/cinnamon color bark, and they don't seem to mind being pretty wet since a bunch of them have grown up right next to the lake. There are so many of them that are blocking light from other well-established trees- we are kind of wondering if it is some kind of semi-invasive species?
