For some groups that have a relatively complete list of all the species known to exist included on iNat, there is a Trends tab on the taxon page that includes 'Discoveries", which are the taxa recently identified for the first time: https://www.inaturalist.org/taxa/40151-Mammalia
I’d see this as ideally a filter, similar to “Popular,” which shows the latest species added. I think this would have major benefits beyond just the enjoyment and motivation of seeing the number of species go up. Two key areas:
Users could periodically set to the “New Species” filter, add filters for their location and target taxon, and check to see if matches for their old obs have been added to the database.
New species observed would get more attention from identifiers, hopefully definitively confirming or rejecting those IDs. This would help prevent additional incorrect IDs being based off any first but incorrect examples of a species, forestalling the potential for widespread errors.
@bouteloua I might be mis-remembering, but I thought there was a way to view these “Discoveries” further back than the green arrow will take you. Like right now mammals only goes back through the six most recently discovered species. Is there maybe an Explore view or something that will do something similar?
I’m going to adjust this feature request from “Display a list/Notify of newly identified species on iNat” to “Notify of newly identified species on iNat” to focus on the request for the notification aspect. (Although technically, after the date of this feature request, we stopped approving standalone requests for changes to notifications).
