<div>I mostly agree with what you are saying and I am just
using your reply as a jumping off point. </div>
<div><br>

<div>There is a significant difference between these three
tags that I haven't seen anyone mention:</div>
<div>
<ul>
<li><b>landcover=trees</b> is an objective piece of
information. <br>
Doesn't matter if the area is 100 m2 or 100 million m2.
By default it doesn't state anything about origin (man
made or natural) or about usage (forestry or park etc).</li>
<li><b>forest </b>and<b> wood</b> are both human
constructs. <br>
When an area of landcover=trees fulfills some set of
criteria (of which there are hundreds if not thousands
different definitions) then we as humans designate it as
a forest or a wood. I would never call the small patch
of trees in my backyard a forest or a wood, but I still
have to tag it as such. <br>
</li>
</ul>
<div>The fact is that a forest or wood can include many
types of landcover because it is itself not a physical
thing, but a human construct. I have personally had
problems with this when tagging named forests. There might
be a small lake or pond within the forest, a small
clearing of grass, or (as mentioned in the forestry
compartments discussion) a clear cut area. These areas are
all still part of the forest, but you can't tag it as such
without just leaving them overlapping (which is why many
lakes now have trees "growing" in them on carto).</div>
</div>
<div><br>
</div>
<div>It would be great if I could distinguish between the
actual physical tree cover (having "physical" tags such as
leaf_type and species) and the concept of the forest (having
"non-physical" tags such as name, operator, opening_hours
and access) since these two features often do not overlap
exactly.<br>
</div>
<div><br>
</div>
<div>A perfect tagging scheme should allow the mapper to add
information progressively and leave out information which
isn't known. I think this is why the landuse=forest vs
natural=wood distinction was doomed to fail. These two tags
forced the mapper to specify the origin of the tree cover
(is it man made or natural) before they could even map it.
landcover=trees (and similar landcover=grass,
landcover=bushes, etc) fixes this problem.</div>
