1. What happens to the surplus elite species (most have very long lives)?
I admit this would be a difficult situation, although zoos do put down various animals, when they can't find alternative homes or when there isn't enough space for the new species and the animals being replaced. How many people check what happens to the animals that leave zoos when a new exhibit with one or a few species in replaces exhibits containing many more species? I don't like the idea of animals being put down (one of the saddest things I've seen on TV concerned two bears being thrown on a skip when Knareborough Zoo was closed down), but I don't think there should be a hierarchy saying that some species can be put down, but other species must always be exempt. Hopefully, the worst case scenario could be avoided by elite animals being kept in sanctuaries.
2. Who decides which zoos get which species, a political nightmare;
Once again, not an easy scenario, but surely this should be based on the quality of the exhibits and how the animals are kept. For example, Howletts and Port Lympne would have the right to kep gorillas and tigers, while other zoos would keep other species where they have a good track record. As I said earlier, zoos could encourage visitors to visit other zoos to see other species, as I tried to do three times on Sunday to people expecting to see elephants at London Zoo.
3. Zoos are unlikely to take the financial risk and go out of popular animals which bring people through the gates and pay wages and conservation donations;
I'm not saying that any zoo should never keep popular animals, just that there should be more of a balance between popular and less popular species. As I've said on earlier threads, I think zoos should be honest about why they keep certain species. They should not pretend that an animal is being kept for conservation reasons, when it is being kept to make money. Many years ago, I had an interview for a wildlife organisation. The interviewer said that the animals were kept to make money, not to conserve the species; I was quite surprised, but I think this is true for many zoos and similar organisations. If visitors have a good day out and learn about various animals, I'm pretty sure that this would be more enjoyable than ticking off a list of ABC animals and learning practically nothing about them. One of my most rewarding experiences as a zoo volunteer was hearing a girl telling her parents that when a spider moults, it takes each limb out of the discarded skin. I'd told her that in the Invertebrate House. There is a lot of interesting information about animals, rather than visitors looking in an enclosure and trying to discover an animal hiding in the corner.
4. Joe Publics and their families (who makes up most of visitor numbers) typically visits their local zoo occassionally (or even regularly) and a zoo or two on their annual holiday. They idally want to see all or most of their favourite elite animals in one space and I believe not being able to do so would lead to a number of them becoming disillusioned and not visiting at all. You've witnessed the disappointment when a zoo doesn't have Elephants, imagine the frustration when, "there's no Tigers or Gorillas either, but we have a nice (sleeping) Binturong and Dusky Pademelon";
Once again, if zoos follow this line, as they have done in the last few decades, so that each zoo contains lions, tigers, elephants, gorillas, giraffes, hippos etc in massive enclosures, so there are even fewer species per zoo than there are at the moment, what is going to happen to the surplus non-elite animals? See question 1. Also, why would Joe Public et al need to visit another zoo if that ha the same exhibits? Surely, each zoo should have a mixture of elite and non-elite and try and encourage people to take an interest in the non-elite animals. I tend to find it amazing that a zoo can have the only example of a species in captivity and doesn't highlight it. Imagine the Louvre not advertising the Mona Lisa. I know it's subjective, but why shouldn't a zoo have a binturong or a dusky pademelon and is a sleeping tiger any more interesting than a sleeping binturong? I must admit, I preferred seeing the active olingos at Kilverstone, rather than the sleeping olingo at Exmouth, but I'm pleased to have ever seen olingos at all. I also miss the white, red and black-headed uakaris at Cologne Zoo and I defy Joe Public seeing a uakari and not showing any interest in it.
5. The idea would never work where there are low concentrations of zoos, e.g. who in the local area would take Twycross' or Edinburgh's surpluses;
While it would be ideal for animals not to be moved over long distances, they can be. Did Edinburgh get its giant pandas from a local zoo?
6. If the public, to my surprise, did subscribe to the idea imagine the extra miles travelled to see what could have been previously seen, at one zoo, by a small journey -it's not really "green".
Is it really green to keep encouraging the elite species to keep breeding, adding to the high numbers of some species, while also leading to the demise of less popular species. Do we really need thousands of meerkats, when there are endangered mongooses that could also make interesting exhibits and could be saved from extinction? The reality is that most of the large, elite animals are being 'conserved' as zoo animals - they're not going back to the wild, either because they couldn't live independent lives or because there is not enough natural habitat for them. If zoos kept smaller species, they could breed them and help replenish wild populations. Is it really green for zoos to allow species to become extinct, because they're not very popular. One of the saddest books I know is 'A Gap in Nature,' which shows many animals that have become extinct in the last few centuries, but are now considered to be extinct. Some of these were kept in zoos, but they didn't have the allure of the elite animals. Another sad book is 'The Last Tsmanian Tiger', which tells of the neglect shown towards the last captive thylacine, which lost out because the dirtectors were more interestd in the type of elite animals that many zoos would prefer us to see.
Basically I think the only way the idea could be carried out, that's not to say it would work, would be if all zoos became one organisation for the whole country (and we all know how difficult to manage effeicently mega-large organisations are) which would never happen. If only most did, it would only take one maverick to operate displaying all the elite species in one space and they'd clean up financially and damage the others survival prospects.
I think realistically, in the UK at least, the current stable situation is as good as things will get (and that's pretty good overall). Lots of species repetition but a number of big and smaller zoos operating and continually improving with financial stability whilst leaving some space (though never enough for zoo nerds) for unusual species to be displayed.
I think it would be difficult for all the zoos to become one organisation, although there is a consortium of zoos, where membership of one entitles you to visit others (I've joined Newquay Zoo, after a visit in 2010). The aim would not be to have all the elite species in one zoo, but to have zoos keeping the animals they keep best. I can't see the point in a zoo keeping a species for the sake of it, when the zoo has a bad breding record with the species or do not have suitable enclosures. I wouldn't want a return to seeing a social species represented by an individual in a bare, concrete enclosure, but neither can I see the point in a zoo spending millions of pounds in building a new enclosure for an elite species that is over-represented in zoos, does not do well in that particular zoo and is not destined to return to the wild. Meanwhile, I don't agree with the atitude that 'non-elite species', no matter how endangered they are, are disposable and, while they could be bred to replenish wild populations, are destined to become extinct. It has recently been announced that South Korean scientists are aiming to bring back the mammoth. Wouldn't it be better for zoos to try and save animals from becoming extinct, rather than spending the animals that they have already saved, no matter how often Joe Public wishes to see them?
