I wrote "natural=land area features are a duplicate of natural=water inner polygon. It will be removed for the next release. Point features will still be there."
I understand that natural=land has priority in the rendering. Rendering will then "move" any overlapping features "under" the natural=land feature. It means you are better remove natural=land area before importing.
The standard case for an island is
- an inner component of a relation type=multipolygon : natural=water
- a polygon : natural=land
- a polygon : natural=wood
Remove the polygon natural=land and the polygon natural=wood will render properly in the hole created by the inner component of the natural=water multipolygon.

Subject: [Talk-ca] Sinking islands...
I was importing data in the Georgian Bay area and I noticed
something. If an island is natural=land it renders in mapnik as white,
regardless of the outer multipolygon. if you have natrual=wood or
possibly others, it sinks if it's not role=inner.
This is at least what I've observed so far. It's rather hard to figure
out when the mapnik tiles get cached and don't refresh in a timely fashion. :-)
