The typical savanna mixed exhibit is probely the most iconic, but aswell most over done zoo exhibit type on earth. After seeing how many zoochaters complained over to loss of ungulates (espicially asian species). Maby would it be a good sollution to create more "savanna style" exhibits for asian species. Like it is commenly done for african species, and even animnals of the south american pampa. Most asian ungulate enclosures are either with a single species or not more than 2 species. With very few big open mixed exhibits done in the style of the afrcan savanna. I know of very few zoo however that do this. (like the big ungulate exhibit in the Burgeri's Zoo) It would create both better living conditions for the animals and make this "unattractive" species (espicially asian deer) more intersting for the visitors. And it could even be very easy done in diffrent enviroments (rain forrest, tropical savanna, or steppe)
