those sorts of comments hark back to an era when zoo collection planning principles really sucked. the reality of the situation is, that gorillas faced, up until the mid 1990s the same future as many other species in this country. to quote peter stroud, the viabilty of the Melbourne program really shifted dramatically only when Taronga imported its group.
in spite of the fact that there has been absolutely no exchange of animals between Sydney and Melbourne the fact that two zoos in the region are actively participating secures the future of gorillas here. the 'unique' mentality is simply not sustainable.
in terms of public relations the gorillas are one of the most important attractions at Taronga. this is borne out in media coverage, sponsorship deals, private support and polling (ZPB NSW ANNUAL REPORT 2001).
finally, we covered the perceived flaws of the exhibit in the approtriately titled thread for elephants but i think when you consider both Melbourne and Taronga have bred roughly the same number of gorillas when Taronga has had less time to do it in that the exhibit cant be too bad.
