Is it a particularly tight site that makes this sort of solution a requirement? All these stairs and ramps seem like an odd thing to find in a polar bear exhibit.
This was intended to give the bears more exercise and enrichment, both the climbing and the rotation between holding day room, small indoor exhibit, and large outdoor exhibit.
So far the zoo has only had cubs and young bears. Whether the plan has faults will be apparent when they have aged animals I think.
Fun Fact: there's another polar bear there who just turned 3 today siku. Arki is siku grandma. arki son Marty is living in toledo and that's siku father.
