I am adding denotation=avenue to trees that are planted to form an avenue,
because you can filter trees within some distance from a road, but not all
of them are there to form an avenue, they could simply be trees close to a
road (but a human would not regard them as part of an avenue). Species,
size and position come into play, something that might be automatically
recognizable with an elaborated system, but it would have to be more
complex than just "within x meters from a road".

Landmark and natural_monument can probably only with additional knowledge
be tagged correctly.
Urban may seem kind of superfluous, agreed (in theory it allows for
detailed mapping of urban trees even in the absence of landuse, roads and
other features, but in reality this will hardly ever happen).

I can confirm that in Italy and Germany (and likely elsewhere) there are
individual trees which are designated natural monuments (by "law") and
which are mapped with these tags.
