As far as I know there has been no import of forest area data. There is a prolific mapper who has made rough outlines of forested areas. Some of these areas overlap with others. Some areas intersect with themselves. I don't think each area represents anything "on the ground", just a convenient chunk to draw a line around.
I will contact that mapper and ask about his or her methodology. There are other "large area mappers" too.

You can find out more at http://area.jochentopf.com I found that there are many problems with self-intersections in South Korea, often on forests. You can see this here: http://tools.geofabrik.de/osmi/?view=areas&lon=128.02487&lat=36.21680&zoom=8 Was there some kind of import? Can you, the Korean community, help with fixing them? How good is that forest data anyway? Is it worth cleaning up? I'd appreciate any information and help. If you are interested, I can also create special Maproulette challenges or create special data extracts or so to help the Korean community clean this up?
