The UN has a definition for "Intact Forest Landscapes". Little of those are left in Europe, the majority in Russia and Scandinavia. Western/Central Europe has only tiny slivers of any.
"Intact Forest Landscapes" seems to exclude any human made forest. So are you against all human planting of forests?

Generally you have "untouched" as in oldgrowth/primary forest and not being a secondary forest, which takes a few hundred years.
The lack of biodiversity is a major concern, since we often take shortcuts by planting cuttings, which are genetic clones, or by using an initial pool that isn't sufficiently diverse.
An artificial forest is better than no forest, off course, but wild, ancient forests are more precious, since they are living DNA libraries.
