for at least the last 15 years taronga didnt have a viable breeding scenario, with only the bull being fertile. ranee died in 1998, rather old and without ever conceiving.
melbourne, maybe as late as 1998/99 might have been able to breed. but with completely inadequate facilities, a pair of animals and no chance to even accomodate another animal. at that stage the only potential would have been in importing burma from Auckland to melbourne to be paired with an Australian bull, for which Melbourne or taronga wouldnt have had the space to house.
pre-import, this would have just left one viable female in the Australia in Perth. Perth also has a fertile, young bull. splitting up a potential pair, and nice little herd to send their female to melbourne, with no space would have been impractical and pointless.
its a tricky situation aussie zoos faced, but the asian elephant management strategy was formulated nearly tens years ago, at a time when the number of fertile animals in the country was as low as 3.1 and at a time when neither melbourne or taronga had space to approtriately house more animals.
even i wouldnt have advocated bringing Burma from NZ to say, Taronga prior to the new exhibit being built for a possible pairing with Heman. so therefore, the situation was as simple as having next to no reproductively viable animals, and no suitable facilities. obviously this strategy recquired a high level of regional commitment in terms of stock and infrastructure, we now have it. lets just wait and see. and please can we take an elephan breather now??? lol
