For abundance you could use organismQuantity in conjunction with organismQuantityType. Both are loosely defined, so just define the terms of your abundance scale in organismQuantityType and use the relevant term in organismQuantity. If you can restrict your terms to a more standard terminology such as DAFOR or BraunBlanquet, so much the better.

Hi Antonio,

Just realized that PlinianCore might also be of help:
https://github.com/tdwg/PlinianCore/wiki It's a standard for species
information, that I don't know much about, but there are probably
other people on this list that do.

Cheers,

Peter
