As mentioned earlier part of the problem is a confusion between tagging what is
there (landcover) and what it is used for (landuse). In the wiki we actually
have a consistent approach (Approach 1) to make this distinction. Using
natural=wood as a landcover tag and landuse=forest for areas of land managed
for forestry. On top of this we of cause still have administrative boundaries.
For me applying this to National Forests would mean:
Using administrative boundaries to mark the entire "National Forest". Remove the landuse=forest tag
except for regions that are clearly used for "forestry". This does not apply to most parts of the
National forests in Southern California that I have seen. Although these areas are "managed" in the
sense that someone administrates it (hence the administrative boundary) most parts of these National Forest
are largely left alone and the possibility to collect deadwood does in my opinion not qualify as forestry.
Finally, any larger regions that are covered with trees should be tagged as natural=wood. Other landcovers
(scrub,water) can also be tagged as appropriate.
The great advantage of the above tagging scheme is in my opinion that it is
very easy to follow for the mapper on the ground. Knowing whether I am allowed
to collect deadwood or not in a particular area is not easy to verify on the
ground, and, in my opinion, not as important as defining landcovers or obvious
landuses. Moreover, it is very confusing for someone that uses the map if there
is a large green region marked as landuse=forest and on the ground there is no
forestry, or obvious management, or trees.

Been following the thread and want to say Torsten sums up the issue very well.
Its an issue of administrative boundary + landcover + land use. And its going
to get complicated to properly model land use and landcover. Relations using
multi-polygons may be needed.
Also I think its been mentioned the boundary should be tagged as boundary=protected_area
which handles the overall mission of national forests is to conserve our forests.
However, the issue comes up that there are different levels of conservation ranging from
untouched wilderness to "actively managed" areas, e.g. sustainable forestry, so
a blanket boundary=protected_area may not be appropriate. Is there another tag that
covers a more mixed bag? Is a new tag needed?
