[Tagging] Feature Proposal - RFC - landuse bush

[Bert -Araali- Van Opstal]

Hi Graeme,

You are confused with the purpose of the "natural" key.  "Natural" is
used to tag natural features, even grassland, rocks etc... and of course
vegetation.  It doesn't matter if it has grown "naturally" or is planted
by humans.

To your first example (https://www.openstreetmap.org/way/434318204),
natural=scrub = GOOD, leisure = nature_reserve = GOOD but is it actually
a nature_reserve ? Nature Reserves can be better mapped as boundary =
protected_area with a protection class. In this case would much better
fit the use and purpose. You can additionally add the key "managed" (not
"maintained", it is "managed"), even define an addtional value for it to
provide more detail. PArts of it seem to have grown to become trees, if
you like to provide more detail these can be mapped as separate areas
with natural=wood.

The second example (https://goo.gl/maps/hj7UpiqKWYGXamHA7) is a perfect
match with an example given in the proposal (see
https://wiki.openstreetmap.org/wiki/File:Example_4_landuse_bush.png). 
True not linear features so NOT barrier=hedge.
If accepted we would tag it as natural=scrub and optionally you can add
managed=yes or managed=clipped or trimmed. As still ongoing discussion
as to provide an extra denotation you could add denotation=decorative or
denotation=landscaping.

Greetings,

Bert Araali
