The decision to move the elephants on is both surprising, and not. I suspect the last nail in the coffin for eles at PZ was the change of WA government and with it the vague promise of the open range facility. The space, while larger with the extension for the females, was never going to be large enough to accomodate breeding. City zoos with elephants need to invest alot of space and PZ was not going to be able to provide more. Added to that was the highest number of keepers per individual animals at the zoo. It will be a sad day when the eles are moved on but it will be a necessary evil (London, Edinburgh and Adelaide have moved on from keeping them). It will be very interesting to see what PZ has planned for the not unsubstantial space. Will it be subsumed into the savannah area to give more room to giraffe + rhino, or will the zoo prioritise space for sun bears and tigers within the Asian rainforest? Obviously new species might also be on the agenda. Indian rhino could be an option, rather than maintaining the whites.
