Ah, that can explain the difference in my interpretation: in French, bogs and
fens are usually designated with the same word, "tourbière", which designates
mires; this word is usually translated in English with "bog". To designate
fens, we say "tourbière minérotrophe", but essentialy only specialists will
know about this difference, most people will use "tourbière" for both fens and
bogs. And now, I see my error: fens are modelled with a different "wetland=*"
tagging, but, my language using essentially the same word for both, I stopped
at the first occurence on the wiki page designating a mire, "wetland=bog",
without understanding that the next one, "wetland=fen", designated exactly what
I was looking for. The problem is the French translation of this page on the
wiki, I'll correct it. Thanks for your answer.
