For me overlapping natural or landuses are broken. An area can either
be a natural=wood or a landuse=farmland. You cant include the same
area in two types of usages or naturals.

So in any case you need a MP relation.

But that might just be me. I have created a validation layer for parts
of Germany for this.

In your specific case - Its a wetland which IMHO implies that it may
fall dry sometimes.
