What to do with Semi-invasive Shrubs
This is a mature woodland with many tall trees. But it is thin in middle layer, the small trees and shrubs. I've cut down some of the invasive species, such as honeysuckle shrubs and some others. But I'm not sure if I need to cut down some of the semi-invasive ones, such as barberry, etc. There are some, but not too many. We do have tons of birs feeding on the trees, shrubs and wild raspberries.
