I like the idea of zoos putting their breeding programs more on display like that, showing rather than telling the vistors the conservation work they do, plus being charismatic, would make a fun attraction
In regards to the Africa section remodel, I was thinking maybe splitting the elephant enclosure into a lion and a cheetah enclosure would be pretty cool and have the overhead tunnel idea everyone's so fond off, then maybe extending the rhino enclosure into the old cheetah one , adding the flamingo aviary over the pond they reside in now. as for south America, I imagine that the zoo may get more capybara in the future, either by imports or coming from other NZ zoos, but potentially having capuchins or more tamrains is a great idea for the left over areas
