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
and the treeline shares the same way.
