For context: yesterday Mateusz Konieczny edited the description of
natural=beach on the Landuse page and commented that "beach is not
always unvegetated and concrete along shore is not a beach", and then
I used his new description on the natural=beach page.
My edit was triggered by
https://wiki.openstreetmap.org/w/index.php?title=Landuse&diff=prev&oldid=1889234
edit that claimed that beach is well defined by
"Unvegetated strip of land at the edge of water."
And that was paraphrased form the original OSM description of a beach.
Main problem with such definition is that strip of concrete/asphalt
along shore
is not a beach.
I thought about dunes when I claimed that "beach is not
always unvegetated" but now I see that dunes are not considered as
part of the beach.
I copied definition from Wikipedia as it seemed far better as it
managed to
exclude stuff like

Maybe copying previous definition from natural=beach would be preferable.
Don't know .. hence my question here .. any 'beach' 'experts'?
Re: > "To me it does not have plants growing on it - so unvegetated."
I agree that beaches generally don't have surface plants like grass -
this can be found in wind-formed sand dunes next to some beaches,
which I would map as natural=sand or natural=dune + surface=grass if
relevant.
However, there are many beaches shaded by coconut palms and other
spreading or leaning trees here in the rainy tropics - the canopy
would extend out over the high tide water line, so the leaves cover a
significant part of the beach (5 or even 10 meters), and most mappers
put the boundary of natural=wood at the end of the canopy. So I don't
know if mentioning "un-vegetated" in the description is necessary.
So it seems that maybe I managed to improve it, but purely by accident.
Overall I am fine also with older definition from natural=beach, page
but I strongly
oppose defining beaches as "Unvegetated strip of land at the edge of
water."
Good point about concrete may not be a 'beach' .. but then what is a
'beach'?
