yass - no doubt the australia zoo elephant enclosure cost a fraction of what melbourne and taronga zoos spent - however, whilst i australia zoo is certainly got an aweful lot more money than most private zoos, i suspect terri irwin isn't half as loaded as some people might expect. the exhibit does indeed have a barn and it would have been a big investment for the zoo. they certinaly intend on becoming part of the regional breeding program for asian elephants, and the other zoos include them as such, but teh big question is "where will they get more elephants?". importing isn't going to be easy at all, especially if they anaimals come from thailand and not a zoo. and what zoo will give up breeding age elephants? my guess is its not going to be easy especially not for a private zoo.
secondly, as the melbourne keeper explained to me on this very topic.. australia zoo will have to invest in building bull facilities with bull-proof fences, something they currently dont have (noor need to). even if they did, he mentioned some concern about sending a bull to a zoo that has not staff experinced with bulls, who have to be managed much more professionally.
i suspect it hasn't gotten any easier without steve irwin around. i could almost imagine an trade with another zoo overseas for elephants taking place whilst he was alive. sadly, i just don't think neither terri nor bindi and going to be able to live upto the marketing power-housing he was able to achieve.
where will australia zoo get more elephants from? they are probably asking themselves the same question!!
