We have a tree stump on our property that will perhaps make a good chainsaw carved chair someday, complete with view. I may keep some of the larger stumps from trees that get removed for any building site or solar access, to use for seats. We’ll likely keep some other trees at half height to serve as natural snags for animals, birds, and insects. Snags are an important part of the ecosystem in any forest, since they provide food (decaying wood for insects, and then the insects themselves) and nesting sites. Snags are a representation of partially down dead trees which sometimes occur due to mid-trunk snaps, disease, or other reasons which killed the tree while the basic tree structure remained standing.
