I agree concerning the social media aspect, but I’m not so sure regarding the studies.
It is going to require being broken down into case by case, area by area studies.
I don’t think the blanket data that currently exists cover the details that are needed to clarify the validity of continued hunting.
I will only reference what I know (Zambia) and I can’t speak for what operators are already doing regarding hippo, but concerning lion, leopard and ele there is good reference data being compiled by some areas and private Unfenced reserves. This is going to be very useful and has been critical in defending lion, leopard and ele hunting op until now. I haven’t seen or heard of anyone documenting population dynamics on hippo and/or the effects or lack of effects on hunting them.
If there are studies, I would be keen to read them.
for example it’s required to compile and report all sightings, of lion and leopard. Tracks, sign, kills. GPS and comments. Try ID features to establish numbers and families etc etc.
That’s where the level of detail that may be needed for hippo to ensure their status isn’t upgraded.
I maybe wrong but I feel this is the direction it’s going to go
