Auckland Zoo didnt breed Sun Bears, that was Wellington Zoo, who have produced three cubs to date.
To be fair until the recent import of the pair to Perth this species has never really had a particularly fair go in this country, and Perth is still the only major zoo to keep this species in a properly designed enclosure.
I can understand the frustration of the members of this forum, but just as we applaud the decision of TWPZ to import into this country the only Indian Rhinos in the region we stand around getting nervous looking at the status of Black Rhino. Ara, I would have loved to of been around in your day when there was such a diversity of exotics but at the end of the day back then you could call a concrete cell and exhibit, import relatively freely, didnt really have to worry about breeding replacements (you just imported them) and could jam stacks of animals into smaller areas and not have to worry about silly immersion-style landscapes or even worse educational signs. lol
I believe our zoos could probably maintain viably a few more species and there have been a number of species listed for phase out which really erk me. For example we have a good represantative collection of New World primates, with various marmosets and tamarins, and capuchin, squirrel and spider monkey yet comparatively fewer Old World species, and the decision to hold on to Colobus and deliberately hybridise them rather than keeping pure De Brazza Guenon is annoying, especially when both are vulnerable, both are 'safe' internationally in zoos, and at the time of the TAG decision both had around the same number of founders.
Where a species is more endangered than a similar species than I think the endangered species should always win out in collection planning decisions. Inevitably, I reckon that over the next decade more species will die out as zoos reorganise their collections and then I predict they'll pretty much do a back-flip and reimport some species, as well as some new ones.
Unfortunately, its unlikely all will make it. Pygmy Hippo may just get through, Collared Peccary or Congo Buffalo wont. Persian Onager.....hmmm. Theyre endangered, yes, but the herd here is highly related so another program that could go down the gurgler. Two tapirs.....will only one make it or will zoos realise they could have both by importing some new Brazilians and giving Malayans a fair go with shady enclosures......Francois Langur; their future hinges on importing more, in the meantime Dusky's and Javans could slip by and we will be 'langurless'. Without fresh genes Silvery Gibbons could also slip through, or at least persist as non-breeding pairs. Dont expect to see macaques in any major zoo, or a great array of antelope, though Impala could make an appearance and save the day as Bongo start having 5 legged calves and our zoos admit breeding mothers with sons to 5th generation is not a good idea.
On the plus side, we will have viable populations of many, many species and in the mean time ARAZPA may have further ironed out the disparate methods and ideas which surely lead to these PMP pitfalls in the first place.
