An example may be helpful here.
There is currently a proposal to merge the 2 Eastern Grey Kangaroo subspecies, it is very likely to happen. At the moment the Wikipedia entry refers to the 2 subspecies and this feeds into the Atlas of Living Australia website and also into iNaturalist itself.
Is there a Wikipedia editor willing to spend the time to process the change? I do not think that you also need to be an iNaturalist curator.
The same situation happened when the Koala subspecies were merged. That change has not been done in Wikipedia and the now obsolete information still appears on all 3 websites.
Hoping that there are volunteers.
I have passed this on to a Wikipedian friend.
I’ve unlisted this post because the Forum isn’t a place to request help about a specific taxon, I’m sorry. That should be done via flags.
