I think you should map a mangrove forest over the water, if tree trunks are
sticking out of water.

In other cases it's a handy approximation, close enough for mapping
purposes.

 Hi,

 Some island are covered completely  with wood. For these island I get a tag
 conflict. Since the natural tag is used for both. I have two solutions:
 1. make a combined tag like natural=coastline;wood
 2. make a 1-way relation for the wood tag and tag the way with
 natural=coastline

 which one is prefered?

To keep my blood pressure low I do not map trees on islands at least
in the current OSM datamodel.

There are two cases the whole islands is filled with trees, and the
islands is partially filled with trees. So are the tree trunks growing
right at the  coastline, or is there a 1m-5m zone where there are no
tree trunks and you are really mapping landcover=tree_canopy? So I've
never really figured it out  exactly what it means when the coastline

 I would go with a relation or even landcover=* and not natural=wood at
 all together with coastline.



+1, I would make a multipolygon relation with the coastline way(s) as outer
member(s), and add natural=wood (if applicable) and landcover=trees to the
relation.

Cheers,
Martin

The first one is a no-no in my opinion. natural=coastline has a rather
special way of being used, not good to encumber it with a
semicolon-notation. My preference would be to have two separate ways,
both using the same nodes.
