[Tagging] Forest parcel with other landcover (scrub, scree…): how to map?

I'm not talking about large areas like the Black Forest, but smaller
forests such as Hondsbossen,
Typically there is a map of the area near the entrances where the
exact area is shown. That map is similar to the one you see on
For an ordinary mapper it might be difficult to map the exact extend,
but what about a government agency contributing to OSM ?

 In this case there is no lake in the middle, so no reason for a
multi-polygon. But in case there is a lake,  what do you do ?
Perhaps could map many of  them as protected areas, but that's
something we are investigating in the Belgian community.

The official National Forest boundary and signs were miles away, surrounding our hamlet, but the land was all privately owned, unlike the actual forest land

But here as well as in the “Black Forest” example, the borders will be very hard to define. Who’s to say where the Alps end and the foothills or valley begins?

>> we generally do not have a working concept for names of many kind of natural landscapes and features. These things typically have fuzzy borders and consist of different landcover and landuse. When I wrote the landcover proposal the idea was to separate named entities from both, landuse and from physical landcover, hence enabling more detailed mapping of landuse and landcover by not being constrained by the name question for the creation of objects .
>> I had envisioned natural as key to define “natural features” with their names, because by then this was still a possible reading of the largest parts of the values (wood, beach, spring, cave, wetland , coastline, heath, grassland, cliff, peak,...) with few outliers but now we have so many things like “mud” , “sand”, “bare_rock”, “grass” that it became less probable it can be agreed on.
>> Maybe we could use “place” for it? In the end, place is about cultural objects, you could see named entities as result of a cultural process (they exist somehow in parallel to the “micro” reality, inside a forest you can find things that aren’t forest areas, but a person would still say they are inside that forest, e.g. a lake or a clearing or small fields. The locality nodes already are used like this.
