To summarize the different points of the recent messages, there are 2
points concerning the tag changes described as an alternative to
landuse=forest or natural=wood :
1) *Landcover :*

   - landcover=trees -> for areas with trees (instead of *landuse=forest*
   or *natural=wood*);
   - landcover=grass -> for areas with grass (replacing landuse=grass);
   - landcover=scrub -> for scrub areas [ *Do we need to replace
   natural=scrub here or does it still give another information ?* ];

2) *Landuse : *

   - landuse=logging -> for areas with logging activities (instead of
   landuse=forest or natural=wood).

*landuse=forest* and *natural=wood **will still exist*, and may be
deprecated (or not) at a later time. I say that in order to convince people
more easily, we could just offer a "better" alternative to the current
tagging, and build up on that ! ;-)
At this moment, I suppose that landuse=forest could still be used (if you
need it) for the other forests that are used for another purpose than
logging (like leisure), until we have better tag for it. But it would only
mean an area "*with some forest usage*" (no longer for the landcover or
logging) !

Note that the landuse should probably be rendered "below" the landcover (if
it exist). It should be easy as it is already what is happening, if you
have a landuse=residential and you draw landuse=grass or landuse=forest,
these are rendered above the landuse residential as both are supposed to be
"landcover". The difference is that we will be able to have better
differenciation like this. One improvement could maybe be to use slightly
different color for landuse=logging than for landcover=trees, so it could
be dissociated ?

Following the general definition of landcover and landuse (used in
geography), they could both coexist next to each other on a polygon (as a
data user could search only for one of them).
