From aerial imagery I would recommend you do not use landuse=forest
as it cannot be determined if the area has some human use to the
tress. Use natural=wood and if you desire landcover=trees.<br>

<br>
There is nothing wrong with dual tagging... use both natural=wood
and landcover=trees, for example of a tree area, indicates what is
there in as clear a manner as possible. <br>
<br>
Nit picking - landuse=* should only be used to indicate the human
use of the land, it should not indicate a land cover. <br>
