What about it is it that you don´t like, Sun Wukong?
As for myself, I would like to see a bit of flat surface in zoo exhibits even when the animal in question live on cliffs in the wild. Just a feeling of mine that even animals like that, now and then, might like to stretch out running or jumping on a bit of flat land.
I guess the "green stuff" right below the rocks is a water moat, not a flat surface accessible to the animals? Or is it actually grass?
For the number of animals kept within, the exhibit is rather small and bare. Secondly, the area (see the buck?) on the very right is all old concrete(though rather flat-@Dan)-a not very nice sight, and although positive in terms of hoof abrasion, not very optimal for the animals' joints. Thirdly, visitors have direct access to the animals from that very side -which triggers unwanted feeding and the potential of injuries on both sides (and don't forget: Salzburg also allows pet dogs to accompany their owners to the zoo). Actually, the ibex should have gotten a new exhibit (next to the wolves) quite a while ago, but this plan was never turned into reality.
