shouldn’t you be able to just merge this into the standard place? (shouldn’t doing so convert all the projects over to the standard place? i can’t really think of any reason not to merge the places, if it’s possible – unless maybe there are indexing stresses.)
yes, this is the country-level place
this is the boundary of the old Taiwan province that is effectively the main island minus the special administrative areas. since some changes in the government a decade or two (or several?) back, i don’t think the province actually exists as a thing anymore, or if it does, i don’t think it actually administers anything. (so i think this iNat place is an anachronism at this point.)
