Araucariaceae happens to be my favourite gymnosperm, but why get all
technical? The "species=" tag is available for that.
What you've got there is a good looking list of what's easily observed
about an individual tree, which is what most mappers can do.  It's
pretty close to leaf_type/leaf_cycle and wood, minus the palm trees.

Existing land cover databases mostly talk about forests, not trees:
And mapping individual trees, as many people are doing for whatever
reason, is slightly different.
