Foreshadowing Exotic Phase Outs (2006)
I came across this interesting article from 2006, which foreshadows the rampant phase outs seen across Australian zoos:
Exotic extinction looms in zoos
Say goodbye to the African elephant, the black rhinoceros and jaguar, for sure. Possibly to the leopard, the polar bear and hippopotamus as well. Most exotic mammals in Australia's zoos are headed for local extinction.
The number of foreign species that the public can see will start to shrink from 127 mammals to as few as 31 in years to come, a survey of the zoos has found.
Their survey, Going, Going Gone. A zoo without exotic mammals? was conducted for the Australasian Regional Association of Zoological Parks and Aquaria. The alarming change it shows includes the loss of 30 out of the 46 different primates - monkeys and their relatives. There would be only eight carnivore species left out of 31 now, and even open-range zoos face a crisis in African hoofed animals such as the hippo.
"The majority of exotic mammal species in our collections are spiralling down a 'tunnel' of extinction, which, depending on the average lifespan of individual specimens is anticipated during the next five to 15 years."
Good find. I've read the Going, Going Gone report previously, but unfortunately don't seem to be able to find it online anymore.
It would be interesting to conduct an analysis of even just the numbers provided in the newspaper article. I think, despite our concerns, the picture today is probably rosier than it would have been thought to be in 2006, which has also been supported by the import of new species, like the Sri Lankan Leopard.
