Man Jai could be realistically bred with Num-oi and Kulab, and could be used as the breeding bull at the zoo. Mali and Dokkon could then be bred through AI, with either Putra Mas, or Gung being the sire.
That sounds like a good plan. I hope they don’t hold off too long on breeding Mali, given that she’s now nine years old.
Another possibility is that Melbourne might split their herd (like Taronga did), with half the female herd going to the Werribee Open Range Zoo. The logical split would be Mek Kapah, Dokkoon and Mali; and Kulab and Num Oi. While the group of three elephants is larger, it’s probably the one that should remain at Melbourne Zoo as it’s the familiar environment of Mek Kapah; Mali is popular amongst Melbourne Zoo fans; and the need to breed Kulab and Num Oi (neither of which have relatives in the region) is greater and will require more space i.e. an open range zoo. They could breed at least twice each, with male calves accommodated in a bachelor herd at Werribee; and female calves remaining with Kulab and Num Oi. Man Jai could be the breeding bull at Werribee; while Melbourne Zoo import Putra Mas from Perth.
It will be interesting to see what elephants the new Sydney Zoo will acquire. If I had to take a guess, I’d say Luk Chai and Pathi Harn at Taronga Western Plains Zoo. The new Sydney Zoo doesn’t appear to have huge facilities for elephants and would probably be well suited to a pair of young bachelor bulls; who are currently in little to no demand for breeding in the immediate future.
