Family of Gorillas to go back to the wild

I really do think that many zoos should treat conservation seriously, rather than cutting the number of species in their collections and continuing to breed animals that have already been saved from extinction. If there is no intention to reintroduce western gorillas into the wild, why are zoos breeding them when there are about 3 times as many captive western gorillas as are needed to save the species? The reason is financial - gorillas are popular zoo animals and many people expect to see them in zoos. A recent thread had zoochatters recommending that Chester Zoo has gorillas - why? I can think of many species I used to see in British zoos and I don't expect to see some of them again. Another thread talked about species that are being phased out in North American zoos, while several Australian zoos have common zoo animals, such as meerkats, but do not hold relatively rare native species, which the government also does not allow to be exported. I think that too much emphasis is being placed on 'popular species' and that relatively unpopular species are being removed from zoos and are facing an increased risk of extinction. Fortunately, some zoochatters are bothered about unpopular species and I am pleased that places like the RSCC exist and that there are threads devoted to small carnivores and the like.
on another thread Johnny made a good point with "Zoo's are there for the same reason people have aviaries, aquariums etc. It's a sort of entertainment. That's what a zoo is for. But, zoo's have gotten a bigger importance along the way. Preservation, education etc."

Zoos have always been about entertainment but as times have progressed they "have gotten a bigger importance along the way". They need the popular animals to get people in so that they can undertake the less charismatic work. Unfortunately it does seem many many zoos use "conservation" as an excuse or justification, and too many treat it solely as a people-through-the-gates business (hence all the replication of meerkats at the expense of perfectly acceptable substitute mongooses).

But all that has been done to death on other threads, so all that aside I think you have two basic misunderstandings with your thought processes. One is where you say things like "If there is no intention to reintroduce western gorillas into the wild, why are zoos breeding them". Humans suffer from a sort of "instant gratification" disorder -- if they can't see something happening immediately then it isn't happening. There is no real need to return gorillas to the wild right now, the purpose of most zoo populations of endangered species has always been "back-up". Some species (mostly small ones) are bred specifically for release, but most (e.g. most of the larger ones) are a sort of contingency population. Ideally gorillas (as the example at hand) can be entirely preserved as wild populations, but in a worst case scenario they are also available as captive animals for reintroductions. Zoos like gorillas because they are popular, but that serves a good purpose (unlike, say, meerkats :D). I think releasing surplus animals (e.g. genetically over-represented individuals) to the wild is a good thing for research purposes, as Perth Zoo does with Sumatran orangutans, because it provides a body of knowledge should it become necessary on a larger scale but otherwise, as Yassa said earlier, releasing individual apes (or other animals) isn't really a good means to an end if it is just to make people "feel good".

The second misunderstanding you have is where you use lines to the effect of "there are about 3 times as many captive western gorillas as are needed to save the species". You say this quite a bit for various popular species like gorillas and tigers. If I interpret you correctly, you are just taking the theoretical figure for which a captive population needs to be to preserve the genetic diversity of that species long-term (let's say 500 individuals for arguments sake) and assuming that is all there needs to be. Once you hit that figure the species is "saved" and it just needs to be kept at that number. That's not really how it works. It is a guideline, a base minimum if you like. Aside from right here, right now, really nothing has been saved. Conservation is ongoing. You don't stop when you have X number of tigers in zoos and say "right, what do we do next".
 
I would add this:
Gorillas have been protected in the wild thanks, in part to the financial incentive of international conservation monies and ecotourist income. At some level, of course, everything can be seen through the lens of financial gain.
They have also been protected (and those conservation funds funded) by the concern of regular citizens around the world.... mostly because (I am assuming here) of the experiences so many people have had of gorillas at zoos and the educational efforts of zoos.
To reduce animals in collections to no more than oddities in an emporium is to insult the work and intentions of zoo people the world over.
Of course zoos need visitors to survive and one must give visitors what they want to a large extent. But there is so much more going on. I object to the simplification, cynicism and naivete of statements that zoos are only focused on the business and that they ought not to focus on the business at all. The truth lies somewhere in between

I'll add this as well, I am saddened that zoos appear to be simplifying their collections. I know of several, for example, that have redeveloped their bird houses and in so doing have reduced the diversity of the bird collections drastically. For me, seeing such variety and diversity of birds (again only one example) in a facility increases my appreciation for birds the world over and the threats to their survival. But there is a lack of imagination about how to fire up the current visitor population about something so seemingly ubiquitous as birds.

I accept that zoos need a few popular animals to attract people that see zoos as a form of entertainment and/or have a limited knowledge of biodiversity. One of the problems is when zoos decide that they need larger and/or additional enclosures for popular animals and these replace enclosures occupied by less popular, and often endangered, animals e.g. more than one enclosure for meerkats

I accept that many people want instant gratification and I’ve seen many people looking to find an animal in an enclosure and then moving straight onto the next enclosure. I suppose they see quite a few animals, but learn little about them. People have complained about not seeing certain animals and I suppose they may feel put out that a more naturalistic enclosure makes animals harder to see than when the animal was exhibited in a bare, concrete box. As natural habitats are being destroyed at an alarming rate, why are zoos breeding animals that they have already saved if there is no intention of sending any to the wild? I agree with David Attenborough that people could save the planet, but won’t. If there is no need to return gorillas to the wild now, will there be a time when there is enough space to return them to the wild in the future? If there are too many gorillas in the wild now to justify reintroduction, why are zoos aiming to breed more of them, thus taking up more space in zoos? As meerkats are popular zoo animals and people want to see them in zoos, why do you feel that they don’t serve a good purpose?

Several years ago, I read an article about how many vertebrate species could be saved from extinction if half the area of each zoo was devoted to endangered species. I think the figure was about 4,500. I have been to several zoos where a very high percentage of the animals are ‘Not Yet Threatened’ and some of the animals are very abundant, such as brown rats. The basic figure for zoos saving a species is about 250 genetically diverse individuals; a few years ago, I remember the minimum figure being 80. It depends how many species you want to save. Personally, I would like zoos to save as many species as possible. I would prefer 8 species with 250 individuals each, rather than one species with 2,000 individuals. Therefore, I disagree with you about the idea of continually building up numbers of certain species, as this can seriously impact on the chances of survival of less popular species in captivity.
If a species is larger and requires far more space, with no real likelihood of being reintroduced, is there really any point in continually breeding more individuals and getting other zoos to take on offspring, while removing other species from the collection? It’s basically a case of having a balance and trying to save as many species as possible and keeping them in a way that will make reintroduction possible. By concentrating on large, popular animals, many zoos are indirectly making some other species more vulnerable to extinction. Smaller animals could be saved, bred and reintroduced to small areas of surviving habitat. The way things are going, many large species are going to be hard to reintroduce, even if this is possible.

I agree that there are many people who have helped to save various species and much of my interest in animals is due to visits to zoos. Many people have also helped preserve animals that they haven’t seen in zoos. A few years ago, I went to Shepreth and noted the information about how different animals are threatened and what people can do to help them. Many of the animals were not found in the collection, but it didn’t stop Shepreth trying to save the animals.

To reduce animals in collections to no more than oddities in an emporium is to insult the work and intentions of zoo people the world over. .
I know various people who are involved in conserving animals. I have also helped provide information for ZSL projects to save animals that are not kept at Regent’s Park or Whipsnade. I am not aiming to insult zoo people or to hark back to an age where animals were kept in cramped conditions for people to feed, prod and gawp at. Many zoo people are dedicated, caring people who often work unpaid. I just feel that zoos should be saving more species, rather than building up larger collections of the same species.

Of course zoos need visitors to survive and one must give visitors what they want to a large extent. But there is so much more going on. I object to the simplification, cynicism and naivete of statements that zoos are only focused on the business and that they ought not to focus on the business at all. The truth lies somewhere in between.
I agree that people have got to be attracted in to a zoo, but once inside, zoos could do more to interest people in the animals that they hadn’t expected to see. One zoo had a ‘paradise tree snake’ on display. Wouldn’t visitors be more interested if it was listed as a ‘”flying” snake’ and there was accompanying audio-visual information about the species? While a lack of knowledge in finance can seriously jeopardise a zoo, similarly a lack of knowledge in animals is not a help. I had a talk with a member of staff at Antwerp Zoo. He said that the Genk Zoo was the worst in the world. The zoo obtained animals, didn’t look after them well and then replaced them when they died, often after a relatively short time. There were no veterinary staff and Antwerp Zoo got fed up with providing free medical care. This is not the kind of zoo I would condone. If animals are to be kept in a zoo, they should be cared for and kept in naturalistic enclosures. It needs a balance between raising money and caring for the animals.

I'll add this as well, I am saddened that zoos appear to be simplifying their collections. I know of several, for example, that have redeveloped their bird houses and in so doing have reduced the diversity of the bird collections drastically. For me, seeing such variety and diversity of birds (again only one example) in a facility increases my appreciation for birds the world over and the threats to their survival. But there is a lack of imagination about how to fire up the current visitor population about something so seemingly ubiquitous as birds.
I must admit that this is my favourite paragraph, Zooplantman. I agree with you and I feel sad when I think of various animals that I used to see as a child and which I shall probably never see again.
 
I've been thinking more about what might have caused the deaths in the Djala group. From the press articles it would seem the wild 'rogue' male 'Boumanga' evidently had something to do with it though they don't know what.

My guess is perhaps this was his second attempt to either take over the group, or drive them away(?) from his area- who knows which, but he was obviously interacting with the group in some way. Djala had no male back-up so the females may have come to his support, given they were a long established group, there were no secondary males in the group, and that they had no experience at all of the dangers of skirmishing with other males/groups from their previous captive life.

The wild male may have then killed or injured the attacking females while fending them off, almost in self defence, or injured them so badly , being far more powerful, that they died later. Its only a theory but might explain the 'strange' killing behaviour, in that he didn't kill them deliberately, and why the younger animals survived if they didn't join the attack- apart from the youngest which was probably riding on its mother.
 
Djala group news.

Having first said they would share further news 'openly' when they had it, there has been no update or further information from the Aspinall Foundation about what happened to the ones in the group that died.

They continue to post upbeat photos of the four survivors though. Someone enquired just the other day on their Facebook as to when a full report on the deaths would be available, and the response was that there wasn't one yet.

I have a feeling that perhaps there won't be one either, and we have been told all we are going to know about this, which is still next to nothing.:confused:
 
Finally.

Aspinall Foundation have finally released another statement giving further details of the timeline involving the deaths of the six females in Djala's group. But basically it just says they don't know what caused them. And gives no indication of what the future plans are for the survivors either.
