I am looking for an opinion on what is the best course of action. I am thinking that part of the basket that has not grown into the tree should be removed, but any parts where the tree has started to grow around should stay. In other words, if removal exposes the cambium layer, it should stay. Any thoughts on this?

I would like to apply this information to help me predict the impact of trees on slopes that will be exposed to major construction. The most important factor that I am interested in is stability.
