Tree Trail

Comment from Island about symbols (somewhat lost a mail, and i quite don't understand the table below):

I think what we spoke about: foliage, rarity and size makes the most sense as a general view:
foliage: the symbol
rarity: the colour
and size(height): the size of the symbol:

up to 7 meters: small,
     >7-15 meters: medium,
    >15 meters: large

            Evergreen    Brevi-Deciduous                   Deciduous              Palms (how else?)
