1. Please check that https://wiki.openstreetmap.org/wiki/Tag:anthropogenic=yes is "approved" for "any natural feature" (meaning `natural=` here)  
2. I'm extending https://wiki.openstreetmap.org/wiki/Key:denotation which is described as usable on "trees" including `=tree_row`. There is no opposing statement on `=wood`, which are also trees. `denotation=urban` already mentions `=wood` can be used instead of individual `=tree` , however the information of `denotation=` is lost if you remove it.
