Ah! I would assume the imported sources were decent

I think mapping them might be decent with SCEE. (Might be in normal StreetComplete as well.) You have to enable the quest type as it is disabled by default, but then it offers the quest and even displays recently used values.

That is if you know your stuff, me I would have to have a tree identification book in my other hand, so I guess a specialized app with that functionality would be neat.
