I was just looking through the IUCN Red List website, as they have had an update today. I have noticed that the Colombian white-faced capuchin, the species in Planet Zoo, has had its IUCN status moved from Least Concern up to Vulnerable in March 2020 (I have included the species' page below):
I'm guessing as changes go its not a big one, but I think it would do a great deal to the game's accuracy to keep the animal's statuses up-to-date. I definitely think this should be part of a future update.
