no because when the ruffed and ring-tailed populations here are filling all the zoos, then the ZAA will decide their priorities lie with white-fronted lemurs, so they'll phase out all the ruffed and ring-taileds and import two pairs of white-fronteds to start up an Australasian-wide population of those instead
Since becoming a member of ZAA I have discovered that you can't really blame the Association for situations such as you describe.
Decisions are made by the members - not the Association itself. I would imagine that the Association has had to cringe sometimes at some of the members' decisions - however, the majority [usually] seems to rule.
It is certainly true that the membership can be fickle in their alleigance to some species - think species such as Dhole and Maned Wolf for example. But, when enough members take a strong interest in a species they have proven to be capable of doing great things with that species.
The trouble can be that senior management - CEOs, Curators, Life Science Directors etc - can change over time and many newcomers arrive with a new broom ready to sweep the zoo clean or a personal favourite species that they want to see in "their" zoo. Other decisions have failed because of unforseen factors completely out of the members' control - failure of overseas programs or individual zoos to make available enough suitable animals, new quarantine protocols, unforseen budgetary constraints, all that sort of thing.
Like most of you, I would like to see a greater diversity of species in our zoos. I am confident that will eventuate. However, now is the time to consolidate what we are working with at the moment and then gradually add those new species as the membership develops the capability to manage meaningful numbers of them.
Still sceptical? Think Bolivian Squirrel Monkeys!
