The discussion is a bit difficult but i would like a few fields which are different populated with different groups (birds has another value list as fish and fish has another list as plants). I understood it was not good for observation fields so maybe it are annotation fields. https://forum.inaturalist.org/t/standardize-and-clean-up-observation-fields/363/12
I made a proposal https://forum.inaturalist.org/t/propose-a-default-basic-set-of-observation-fields/438
The same field appearance’ (plumage) for Birds (=1)
The same field ‘appearance’ (plumage)for fish(=9):
The same field ‘appearance’ (plumage) for Plants(=8/10):
And another field with stadium with for example the next values
