I'm late, but fantastic news! I congratulate Taronga on immediately announcing a replacement for their elephants, easily the most exciting option of the four!
Comparing the elephant phase-outs and their replacements -
Taronga - Indian Rhinoceros / Asian Waterbuffalo
Perth - Expanded Savanna
Auckland - Expanded Savanna
Melbourne - Unannounced
I hope Melbourne is cooking up something else other than just developing what will be the largest habitat in the world for just three orangutans. I know Adelaide plans on continuing with both Brazilian Tapirs and Sun bears so I hope Melbourne can get on board with an import of either. Personally, a Sloth bear, Brazilian Tapir combo would be my wish.
I also wonder if Melbourne or Perth asked about acquiring Hari only to be shut down by Taronga. Makes sense why Perth floated the idea, before finding out Taronga would be keeping him to fill their own elephant gap.
It will be interesting long term to see what they do. With the elephant house having multiple hold areas. If they will eventually split the habitats lower and upper areas and get hari a mate. Split the lower area to redevelop. Or keep it exactly as is.
If I were to wager, Taronga will probably never be used for rhino breeding, It's just too small. Hari wouldn't even be able to work up to a full gallop with both areas opened up. Likewise, the waterbuffalo will probably only be kept on-site if they integrate well with Hari, otherwise, Taronga will most likely palm them off to TWPZ. Axis deer could also work well and would be better able to evade Hari in a tight space.
Still, though it's exciting and I could see an excess rhino at Taronga indefinitely as an ambassador for what hopefully turns into quite a successful breeding program at TWPZ.
True, it is however space that they could have looked at and kept bongo instead of designated them a phase out. It is where I imagine they were going to put okapi. The elephant house is heritage listed, so while they can/have changed the inside to a degree. It isnt able to be knocked down. It is a nice piece of history for the zoo. The yard is decent sized and flat. It's held giraffe, camels and elephant. A larger ungulate would be suited to it, with only exhibit redesign of planting etc needed. Personally I think it would be a good site to redevelop into a pygmy hippo set of enclosures with how flat it is.
Personally, I'd like to see the bull exhibit be dedicated to pygmy hippo and divided into 4 areas, one within the barn and 3 externally. Two deep pools already exist there and that way Taronga could have a comprehensive pygmy hippo breeding program of 4-5 hippos on site, in a 1.2 + (maturing offspring) arrangement. I feel the region needs a pygmy hippo breeding hub to prevent stagnation and Taronga could easily facilitate that.
Otherwise, I think Sri Lankan leopard could suit the area, especially the temple. However, that would require a more costly renovation, and the fact that our major zoos seem to despise the idea of housing Sir Lankan leopard.
