The issue with a lot of our ungulates, we imported a lot of good species. Then the doors shut for a very long time. Most species that were imported were done in the era where every zoo was for themselves, which we still see a bit of. Then genetics became a problem and a lot of them were left to die out, while they have inbred to a high degree others to maintain the small diversity we have. No the doors are open again. Our main zoos with the largest amount of money are only interested in squeezing money out from building money generating projects, as the zoos are run by corporate and not animal based people. These are the people that won't spend money on importing Thompson gazelle because Indian antelope look similar and can work as a stand in on the savannah. Until this mentality changes, we won't see any majour progress. Not until they start prioritising species again. Then we may see an uptick in imports. For now it's the private players who are catching up and setting up zoos that now even rival the big zoo's, and they are doing the heavy import lifting with a fraction of a budget.
The decrease in diversity of species held across our region’s zoos is a notable trend. 100 years ago, zoos could readily import a plethora of species from the wild via animal dealers. Some of these thrived in capacity, some of them didn’t.
Long before the era of coordinated breeding programmes, zoos identified animal exchange and breeding as a cost effective alternative to purchasing animals. There’s countless records of the prices hippopotamus calves could be expected to fetch overseas; as well as exchanges between countries.
While zoos operated independently of each other; as a consequence of the above, there were still a degree of homogeneity across the collections as species that bred in sustainable numbers were exchanged and populated multiple zoos across the region. Chacma baboon and Barbary sheep are both excellent examples of this within a historical context. This trend only strengthened once taking animals from the wild became prohibited and zoos became reliant on captive breeding/animal exchange.
Ultimately, Australasia has a small number of facilities compared to other regions and is geographically isolated. We can expect homogeneity of species to reign supreme as it’s productive in every sense to hold species that can be managed in sustainable populations. Exceptions will exist (Indian rhinoceros are an obvious example), but they’ll be few and far between.
