I hope the elephants in captivity debate will die off once most of our elephants are located in large open-range settings. We are heading to a future where only the two Sydney zoos will hold elephants in smaller exhibits. Monarto as mentioned by myself and many others before is the only viable new future holder of this species in the region, thus them joining would be a massive boost.
Unfortunately, Monarto hasn't officially announced whether they as an organisation are still interested in holding elephants, let alone if they will be African or Asian, or even further, whether they plan to hold a non-breeding/bachelor or breeding herd. So a lot of this is speculation, from chats with keepers I still believe they are interested in elephants (likely Asian) but are still a long way off from getting them, possibly 2035/40.
A bit of speculation but if Monarto were to house a breeding herd how would they form it? I see this as less likely than a bachelor herd, but it is still a possibility
Personally, I could see Monarto receiving Num Oi her matrilineal line/calves and Kulab (a close friend of hers). This move would essentially split the Werribee herd down already developing fault lines. In 15-20 years, Dokoons matrilineal line could be quite large, with herself, Mali and potentially 2-4 other young adult daughters/granddaughters, not to mention calves. Therefore I could see both space and social issues arising at Werribee. Once at Monarto I could see Num Oi's line paired with one of the young Irish bulls from Sydney, as he will be unrelated to her daughters (unlike Luk Chai) and also still relatively young (unlike Putra Mas who will be close to 50 by then). Monarto could also use a matrineal line from TWPZ as its founder but I don't know which one.
This will be a great way to honour her, she's probably one of the most influential elephants in Australasian history.
