I absolutely agree with this part in particular. Specifically, I really think that the Cassons would be a decent enclosure for Sumatran Rhinos, and if they replaced the Red River Hogs it could be a great start to the building becoming a Sumatran/Southeast Asian hub
They’re only barely larger than the pigs, and it would probably be two individuals (2.5 with a calf) instead of a small herd. It’s also a good tie into ZSL’s conservation work, and would allow them to advertise the return of rhinos (without having to put the larger unsuitable ones in).
The main thing keeping it from happening is the disastrous record Sumatran rhinos have in captivity. Out of 40 captive individuals (worldwide not just with ZSL) there was only one successful birth, and their captivity is now so heavily regulated/rare that it’s unlikely it could happen for some decades yet.
Still, I really hope it does, because the Cassons are kinda barebones at the minute. Inside access is usually cut off, and ever since they removed the camels and tapirs it’s not really carried any large mammals.
Obviously it was never properly suitable for elephants (at least not in healthy numbers), and hell will freeze over before they ever return there. But I do want to see something done with it again, because it’s really just the pig house now
