well i think there's way to much going on at the mappin terraces. and i'm not sure the andean bears or the tigers will fit where you put them.
Not much room for the elephants when you consider they need a large house too. The casson yards are too small for indian rhino and gaur unless they were to be expanded, and I agree with foz's statement.
Yeah, I don't think there would be enough space for all these large animals. They're better off at Whipsnade... Although now the pygmy hippos are where you proposed, so that's cool!
