Hey, thanks for your feedback.
I have commented on the original changeset for the trees, asking for clarification. I also looked through some of their other edits and noticed they do infact add height as one of the tags to trees, but also sometimes a diameter, incase they don’t respond back to me, I will add the tags back as height and add a note referring to this changesets discussion,
I noticed there were way more values which have misspellings in them (although those are pretty easy fixes), and some which do not really make sense. I decided to only do these for the time being. I am still thinking of a good way to resolve the others and how to discuss it with the community to try fix these on a schedule.
You can view some of these tags by going to taginfo and for example going to the highway tag and going to the last page, there are some mentioning which highways they’re near (mostly in persian, where i mainly do my editing), which isn’t the correct usage of the highway tag, and should probably be moved into a subcategory under addr, as I mentioned this is probably going to keep on happening so there has to be some way to keep repeating the changing of these tags and maybe having some guards of adding these tags wrongfully. 
Kind Regards
