Re-homing nature: A step too far?

Richard Black | 14:27 UK time, Monday, 18 April 2011

Sir Richard Branson's plan to introduce lemurs to islands he owns in the Caribbean, which I reported on Saturday, has thrown into new light a real dilemma facing conservation scientists as they struggle to contain and reverse the loss of species and ecosystems across the world.

Red-ruffed lemur

The red-ruffed lemur is among the most threatened

Lemurs are Madagascar's most iconic animals, very old in evolutionary terms and seriously enchanting to the human eye.

And they're seriously threatened - some species more than others - principally by deforestation.

As always, the first requirement for effective conservation is the effective rule of law.

And many reports indicate that since the overthrow of President Marc Ravalomanana two years ago, the country's civil turmoil has resurrected the climate of opportunistic environmental plundering that the deposed leader had done much to curb.

With some lemurs now facing extinction in the wild, what would be more natural than to think of taking some of them somewhere else - in Sir Richard's words, "giving them a new island" - where they can live in peace and tranquility?

At first sight, it's a solution that could be implented on a wide scale. Indonesia alone has about 7,000 uninhabited islands - why not set up a scheme that distributes imperilled plants and animals from southeast Asia between them, for example?

If something seems simple and straightforward, there's usually a reason why it isn't being done already.

And in this case, there are several.

There's a saying "marry in haste, repent at leisure"... and it appears to be especially true when the marriage is a forced one between components of different ecosystems.

Well-known examples would include the introduction of the rabbit and the cane toad in Australia. But we can add birds and plants to Hawaii, possums to New Zealand, lampreys to the Great Lakes of North America, and rats on countless islands.

So when conservation scientists sat down a couple of decades ago to write a set of guidelines on how and when introductions should be used as a tool for conserving species, they were naturally cautious:

"The damage done by harmful introductions to natural systems far outweighs the benefit derived from them.

"The introduction and establishment of alien species in areas where they did not formerly occur, as an accidental or intended result of human activities, has often been directly harmful to the native plants and animals of many parts of the world and to the welfare of mankind."

Introductions, it continues, have resulted in a few species coming to dominate a large number of ecosystems as they either eat, infect or out-compete the traditional inhabitants.

Even worse:

"Islands, in the broad sense, including isolated biological systems such as lakes or isolated mountains, are especially vulnerable to introductions because their often simple ecosystems offer refuge for species that are not aggressive competitors."

The guidelines - developed by the International Union for the Conservation of Nature (IUCN) - don't say "never do it". But they do say "tread carefully" - because obviously it would be hugely ironic if introductions with a conservation motive ended up doing damage.

Kakapo

Kakapos have been given to new homes - but not far away

So far, species introductions have mostly been used over small distances, in situations where the original habitat has become impossible.

Several New Zealand birds, for example, such as the flightless kakapo, have been successfully introduced to islands off the coast after human expansion and newly-introduced pests meant they simply could not survive in their native lands.

A particularly intriguing situation concerns the Kihansi spray toad, one of the world's smallest amphibians.

It lived in a single waterfall. Now that habitat has gone - construction of a hydro-electric dam first dried up and then polluted the water supply, and introduced the lethal disease chytridiomycosis.

Discussions are ongoing as to whether captive populations should be introduced to a similar waterfall, and if so, where; but certainly its native home is not an option, and perhaps never will be.

But taking a species from one continent and "giving it another island" on the other side of the world as a place where it can live more or less in perpetuity - that is, as far as I can ascertain, unprecedented.

The islands are Moskito (also written Mosquito) and Necker, in the British Virgin Islands (BVI), which Sir Richard owns.

Clive Petrovic, a BVI ecologist whose CV includes contributing to global assessment of coral reefs and cataloguing local butterflies, led the Environmental Impact Assessment in 2007 for  Moskito Island.

He tells me that although they did not specifically evaluate the potential impact of lemurs...

"...in several places in the assessment we cautioned against non-native introductions."

He elaborated:

"You should realise that there are no lemur-sized mammals native to Moskito or Necker because the islands cannot support such large animals. Therefore, it is almost certain that lemurs would not survive long on the island without significant care and feeding.

"Further, there are toxic plants native to the islands that could possibly harm lemurs, and at least two native raptors are large enough to prey on young lemurs. Also, the lemurs may negatively impact native birds or some of the rare reptiles and that could become a problem."

At least a dozen species of bird nest on the island, he said; and some lemur species are partial to eggs.

Dr Petrovic was at pains to point out that Sir Richard has been ecologically an excellent custodian of his islands, and has gone to great lengths (and expense) to conserve and improve the environment.

Sir Richard also told me that if problems were to arise - if lemurs started eating the dwarf gecko, for example - he would take measures to deal with that.

However, even if these local impacts can be dealt with, then if Clive Petrovic is right and the island can't support lemurs without constant human intervention, one has to ask whether this project really meets the criterion of giving the animals another island.

It would, however, meet another aim of Sir Richard's - to give captive lemurs a better home than the ones they currently have in cages in zoos.

We're not talking about all zoos here; but some he's targeting do appear to be keeping animals in less than optimum conditions.

But that's an animal welfare issue, not a conservation issue.

Sir Richard Branson

 

The potential biological impact is only one reason why conservation scientists tend to regard species introductions as a last-ditch measure.

Iconic animals such as lemurs are seen as ways of leveraging money and political pressure that can be used to conserve the whole native ecosystem.

Some of the activists who began campaigning to "Save the Whale" all those years ago were actually interested in the entirety of ocean life, but used whales as a flag around which governments and ordinary folk could rally.

So it is with lemurs. Use their iconic value to save the Madagascan forests, and you also preserve the entire ecosystem, not just its cuddliest component; that's the argument.

So there is concern about the potential impact of sending a message - however unwittingly - that could be taken as meaning "the animals are OK because now they have a second home".

Some also find it a difficult ethical issue.

Who are we, they argue, to distribute species around the planet according to a set of criteria that we develop ourselves and which may well contain a deal of anthropocentric reasoning?

The counter-argument is that we've been redistributing species as long as we've been travellers, and have wrought more profoundly damaging change - usually by accident - than anything we're likely to do through the unintended impact of conservation programmes.

Yet more opposition comes from the idea that there's obviously a limit to what species introductions can achieve.

Could we, for example, take the endangered snow leopard and find it a couple of uninhabited islands, perhaps in the Canadian Arctic? To where should the northern black rhino be transplanted?

As summer sea ice in the Arctic becomes a scarce commodity, are there any uninhabited islands around the Antarctic that could take on some polar bears?

And what about the oceans - how does the notion of second homes work there?

So - the argument goes - let's just set this limited and problematic idea to one side and concentrate on the fundamental aim of conserving places where the animals actually live now, and to which they're optimally adapted through millennia of evolution.

There will doubtless be readers who take the view: "yes but we've still got to do something", and would applaud Sir Richard unreservedly for offering sanctuary to some of these undeniably charming and fascinating creatures - and perhaps wish that other people would similarly get off their richly-caveated backsides and actually do something.

And I'm sure everyone concerned about nature would wish him well with the venture.

However, there are concerns out there. An e-mail I received from another ecologist who has worked with lemurs asked simply:

"Haven't these guys seen Jurassic Park?"

And while that over-dramatises the situation, the wider issues demonstrate that saving nature is about far more than giving it a new home.

    Branson is a successful businessman. Unlike all these taxpayer supported ecologists who are screaming from the roof tops, Richard has had a net beneficial contribution to society. Richard has added value rather than become a parasitic worker that leaches off others by "crying catastrophe" and getting taxpayer funds for more useless ecological studies!

    If Richard wants to introduce Lemurs to HIS islands then I say let the man do what he wants.

    All this red tape and enviro mumbo jumbo about you can't do this and you can't do that!! Frankly, the hard working people of this world with REAL jobs are getting sick of taxpayer funded loons (in Uni's, NGO's and Government) screaming about the catastrophic consequences of just about everything and anything.

    The only catastrophe is all these taxpayer funded eco loon pseudo-scientists who without handouts would not be able to survive! These are the species that need help in escaping their parasitic existence.

    .. 100% correct.. this sort of well meaning tinkering is merely a side step away from a zoo.. dealing with the issues these species are facing in their natural habitat is sustainable and costs less. the animals evolved there, so there will not be any unforeseen issues concerning 'invasive' introductions or failure to adapt to a new environment... Mr Branson is on the wrong track.. worse, this is exactly the sort of misguided intervention that the anti-environmental lobby love to trumpet as a viable answer to biodiversity loss.. which it is not.. its Nero picking up his harp, while the skyline glows....

    An interesting article Richard,and so far I am in agreement with the other Richard
    (Branson).There may be voices against the idea,but they would do well to balance
    their negative stance with the very reason that Branson has suggested this,to try
    in a small way to cancel out the enormous damage done by man.

    Mankind is consumed by greed and if deforestation has a monetary outcome then no
    amount of reasoning will stop it.They care not if animals are harmed,and what can be more harmful than plundering their habitat?

    We see adverts on TV imploring us to send £3 a month to eradicate the horror of
    children starving to death.The next advert will beg us to send £3 a month to save
    the jaguar or tiger from extinction because man has encroached on their habitat.
    This problem goes on repeating itself and will do so as the global population rises.

    I feel so sorry for the children brought into the world where lack of food causes such
    suffering,but I feel angry that animals are the ultimate losers.Man has taken and taken from the animal kingdom,shot,snared,poached and treated with cruelty.If Branson can in a small way help to redress the balance then I applaud him.

  • Comment number 4.

    Wasn't there a scary and unmentionable disease in Madagascar just recently? I am not sure which species it hit, but the lemur sounds like a likely candidate. Jurasic Park was a story about bringing back large highly visible extinct species.
    It is the smaller, and hopefully extinct, species that I wouldn't want brought back to life. Has the lemur idea been fully thought through?
    Two of the creatures in the photographs look cute and cuddly but I am not sure about the third one.

    @1

    .. If there is no 'catastrophe' why is Branson offering to help conserve lemur species?

    .. neoconservative ranting doesn't change the science.

    Petrovic's concerns are valid and unlike Branson, he is a qualified zoologist.. Branson on the other hand "took six months to blast the top off" (his words) Devil's Hill on Necker to build his house.. it is also worth checking the environmental credentials of Necker Island .. very few trees and very little natural water either... a human 'survival' team visited Necker before Branson bought it.. they lasted just 14 days before terminating the expedition....

    .. and interestingly Mr Branson does not appear to be in a position to discuss Moskito (Mosquito) Island as a prospective Lemur reserve, since he appears to have sold it to Split Holdings (not in the Virgin Group of companies) in 2010..
    'The sale was disclosed in the 2010 financial accounts for Virgin Holdings, one of several entities that control Sir Richard’s global business interests.'

    ... three other facts that put Branson's rather less than realistic conservation scheme into perspective -

    Madagascar covers an area of 587,041 sq km

    The United Kingdom covers an area of 243,610 sq km

    .. and Necker Island covers an area of 74 acres

  • Comment number 8.

    I definitely share Richard's (Black) concern over the other Richard's simplistic thinking. This is just another case of introducing an alien species into an ecosystem with unknown consequences. On the other hand, he could just call a spade a spade and call his island a zoo. And if saving a species from actual extinction is the goal, zoos work for that in an emergency. That's how they kept the California condor from disappearing... and there are now more Siberian tigers in zoos than in the wild... etc.

    And Richard explains the obvious: "Iconic animals such as lemurs are seen as ways of leveraging money and political pressure that can be used to conserve the whole native ecosystem."

    Not to mention using them as leverage for the great AGW project... like the polar bear. Unfortunately this use produces junk science research on these species to exaggerate their plight, to provide this leverage... as in the polar bear.

    But... Richard... this is particularly dumb: "Could we, for example, take the endangered snow leopard and find it a couple of uninhabited islands, perhaps in the Canadian Arctic?"

    Really? You think that the snow leopard eats snow? You could have come up with a better example than this absurdity.

    In any case, the musings of a self-absorbed egomaniac like Branson is hardly worth talking about. This 'conservation plan' demonstrates how clueless he is on this.

    Update on ownership of Moskito (Mosquito) Island -

    Ryan West, variously described as Necker's Chief Engineer and Moskito's project director / manager (depending on the source) appears to have dismissed reports of the sale.. curioser and curioser...
    https://blogs.forbes.com/eco-nomics/2011/01/27/richard-bransons-eco-resort-plans-still-on-track/

    ...this does not change the fact that Necker Island is approx 0.3 sq km and Moskito Island approx 0.5 sq km of unsuitable habitat for Lemurs.. a zoo, is a zoo.. Branson could achieve far more by dedicating his undoubted media savvy and resourcefulness to ensuring adequate funding for lemur conservation measures in Madagascar... since any suggestion that free publicity for Virgin Limited Edition projects was a motivation, is of course completely unfounded....

  • Comment number 10.

    Good blog about a fascinating issue.

    In general introductions have been a disaster, but they have hardly ever been done for conservation purposes. If it is properly thought through then it will work - but that depends on the criteria of the project.
    Branson is basically setting up a safari park/zoo to conserve some of the species from Madagascar. Introducing the lemurs is sure to change the ecological balance of his island, but is that a problem? That depends on whether the native flora and fauna is also at risk (I suspect not). And because it is a relatively small island, it won't be a wider ecological disaster if it all goes wrong.

    No 9.: ''..ensuring adequate funding for lemur conservation measures in Madagascar...''
    That's not going to happen. it is clear that Madagascar is a disaster zone at the moment.

    No. 8: ''the musings of a self-absorbed egomaniac like Branson is hardly worth talking about''
    Make your mind up - you clearly have something to say about it!

    I commented on the topic. The whole article could have been written without the reference to Space Boy but I suppose that gave it the 'celebrity' status that caught Richard's attention.

    Perhaps the next article will be based on the musings on the Queen's simple son.

    #13 Geoff. Yes, have been a little extra-cranky in my comments of late. Will try to be nicer. I suppose I should have responded more nicely to your absurd comment about bears in North America in the last thread, so it would help if you didn't toss out such red flags.

    You do know that there is even a black bear 'problem' in New Jersey now, don't you?

    How was that? Nice enough?

  • Comment number 14.

    A rereading of the classic The Theory of Island Biogeography, by Robert H. MacArthur and Edward O. Wilson, Princeton Univ. Press will help people understand why relocating Lemurs from a huge island to a tiny one will not work, unless one wants to make the the tiny one a zoo.

    If Branson's concern is primarily with protecting Lemur's, he would more likely be successful by purchasing critical lands to add to Madagascar's National Parks and then hire the guards to protect them from the ever expanding population. He could also contribute to family planning clinics in Madagascar along with advertising to promote the advantages of small families.

    #15 Well, grannie, I would do what Walleye suggested in his #14. That would be the most effective action and would earn Branson well deserved recognition. There could be a Branson Park.

    This particular announcement sounds like a poorly thought out publicity stunt. Look, I'm putting lemurs on my island! Sell the island and use those funds in Madagascar. Or at least do something for the native species of the island instead. Why lemurs there?

    And for Branson the businessman, it wouldn't hurt if more people wanted to fly to Madagascar. Win-win-win.

  • Comment number 17.

    @Many

    If the man wants to build a zoo then I think we should let him, but I do agree that if he wants to actually save lemurs and other less popular flora and fauna, both he and they would be much better off if he bought up bits of Madagasgar.

    For those of us of a more limited means, but who still want to "save" a bit of rainforest, this might be of gerneral interest(Hopefully, the mods will let me post this link):

    https://rainforestrescue.sky.com/?pc=AGZ003033

    If not, there are a number of "rainforest rescue" programs and a simple google search will suffice. You don't need to be rich to make a real difference :-)

    Issues like this(diversity and habitat protection) and ocean no take zones are really the sorts of things we should be concentrating our efforts on......

    Our ship is sailing back on course. Thank you for your empowering link blunderbunny, and thank you CanadianRockies for your change of tack.
    So where are we:
    If it is a zoo, call it a zoo.
    If it is purely a business venture call it that, but support others at the same time to earn respect.
    We can all contribute to supporting the environment and blunderbunny has provided the link.
    Madagascar could do with sustainable help and development.
    If our subject decides to take the path less travelled, would he receive recognition for his altruism?

    ... seems to me this is a classic case of 'the road to hell being paved with good intentions'...
    This appears to be about as well thought out as those witless Animal Rights Activists releasing Mink all over the shop, and look at the disastrous consequences of that!
    I think the real issue, as always, is the ever-expanding number of humans on this not-so-large planet, and until we can sit down and have a meaningful, sensible and non-hysterical conversation about what to do about that, I fear any attempt at conservation, good or bad, will be doomed to failure in the long run...

    Not sure how many exactly how many times we're all going to find some common ground environmental issues, but it's nice when it happens. I used to think of myself as green, but the issues that we normally blog about here and elsewhere have sort of clouded that particular personal definition.

    Still, I try and do my bit rather than just blogging about it and hopefully, some others will follow suit. As with all of these things, small positive actions on behalf of individuals can have significant effects when multiplied up. There are, after all, quite a few of us ;-)

    Sometimes a hard man is need prepared to take hard decisions if the masses are to be prevented from trashing the environment.

  • Comment number 22.

    personally i think the idea of using 'totem' species to highlight the issue really deflects from understanding the wider issue - habitat destruction. whether we can or cant save a few large species by dotting them around the planet on islands is rather irrelevant if we continue destroying habitat at the current rate.

    every penny planned to be spent creating new habitat (as mentioned, really just big zoos) should imho be spent on conserving the habitats that cover the global hotspots (ecosystems that contain a large diversity of species).

    of course it's not my money to spend and i would rather it was spent on any conservation rather than something like space tourism but this really highlights an issue with the 'small govt' perspective of the extreme right political groupings. the bottom line is you cannot control what extremely wealthy individuals want to spend the money they have accumulated (often by trashing large parts of the planet) on.

  • Comment number 23.

    Why doesnt Branson just buy x thousand acres of Virgin Madagascar rainforest to preserve it for the lemurs?

    He wouldnt even need to rename it!

  • Comment number 24.

    Thanks Walleye for the Island Biogeography bit - I was just about to start my bit on the subject but you beat me to it.

    The key aspects are minimum size of appropriate habitat and food/predation balances. I was intrigued by the article suggestion of toxic plantlife -I can see something in this.

    On the size issue, 45,000 ha. would be the appropriate minimum (Ranomafana National Park, Mad. is of this size); geographically - 15-30 South; climatologically - dry tropical/monsoonal, 1500-4000mm; geology - preferably limestone with broken territory & some elevation; etc.

    I favour the least logged of the Tanimbar Group in the Indonesian archipeligo, west of Papua New Guinea.

    I am not averse to this experimental transfer.
    It would confer protection on the chosen island, thereby protecting the indigenous species from humans and further logging.
    The lemur impact on the island flora and fauna would be part of the monitoring & research programme.

    @ Shardone

    You are so ignorant and absent minded it beggars belief. Just because someone is a succesful businessman does not mean they have the right to disrupt an ecological system, whether they own it or not. Now I'm not stating that Richard Branson isn't well intentioned, but that doesn't mean he is right.

    And no, 'real working people' are not all getting annoyed by the increase of environmental issues in the press, you don't have to be a tax payer funded 'eco loon' to appreciate the huge amount of biodiversity loss that is currently underway as a result of human pressures. It's people like you that are the real problem; if you're not interested in the natural world and conservation then fair enough but you don't have to attack the peole who are and who are trying to do something about it. I'm guessing you have never been to Madagascar because if you had i'm sure you would be more aware of the environmental, and social, 'catastrophe' that is unfolding there. Perhaps learn more about the subject before you criticise those involved in it.

  • Comment number 26.

    i think this also leads on to a tougher question, what are we saving these species for?

    from my perspective a species is much more than a few token individuals. it includes the record of continuous evolution preserved in the diversity of a particular population. it includes the behavioural interaction between species in an ecosystem. it includes the way a species alters the non-living habitat that indirectly affects other species in that habitat.

    so transplanting a few individuals to a virgin (literally!) island is pointless unless the objective is to restore them to their original habitat.....which does not appear to be the case here. in fact as you mentioned richard, in some ways it could make the original habitat more vulnerable.

  • Comment number 27.

    It seems to me me that you can please some people some of the time but not everyone all of the time. Environmental issues touch the heart, and reach into the recesses of human emotion. I am touched by all these stories of endangerment, and to be honest I don't know what the future for some of these animals.

    Suffice to say it is now a global problem and I live in the UK. We have a safari park in Kent and many endangered species live here. The greatest danger faces in my neck of the world is sewage pollution.

    Whether exotic animals or the British wildlife, pollution affects them all. In the sewage industry they have just produced sewage treatment plants that have literately no carbon footprint and their discharge is 99% pure. The www.theseptictankshop.co.uk has for many years been against pollution of the environment. It must be tackled now.

    The world leaders talk to much at times.
    Many people on the ground such as surfers against sewage are fighting hard to protect our environment.

    Please let us stop this madness.

    Hi, Rockies. Yes, I have had close encounters all over New England – usually doing early morning photography out of my touring ‘Bed & Breakfasts’. They seem to derive pleasure from frightening me when I turn the corner to pick up the hire-car from the back lot.

    In general terms, species diversity and variety of large mammals is limited - largely as a result of the post-glacial human expansion through the Americas involving the extermination of ‘naïve’ prey spp with no prior exposure to human hunters (Jared Diamond) – and with low diversity comes higher numbers of limited species; hence the black bear.
    This is the classic ‘pest species’ phenomenon, where a species expands in increased numbers into niches previously dominated by erradicated spp.

    Perhaps it’s the ecologist in me, but I was frustrated by the lack of discussion, and the lack of depth of discussion, on Richard’s last posting.

    Incredibly important topic, cut short. But at least it will return when the conference report is published.

  • Comment number 29.

    Well, I do applaud the well-meaning intentions of Sir Bransom but i also see the side that says 'these animals have had their shot'. I guess EVERYTHING 'has its shot' and then passes on. Millennia from now, some specie from somewhere may well be saying that about us. Scary thought, isn't it?

  • Comment number 30.

    If Richard Branson really cared about the environment then he would donate the vast majority of his fortune to organisations like the IUCN so that they can do their reserach, protect Endangered Species from poaching and provide viable sources of income that don't destory the enivornment for local people living in these countries. It's nothing short of a publicity stunt to get people to buy his services/products by thinking he cares about the environment. The fact that one man can "own" an island shows where the real waste of money is going.

  • Comment number 32.

    Was a great read.There is definitely a fine balancing act involved.Would there be less controversy if the Island option just catered to Lemurs who are housed in poor conditions at Zoo's- so rather than a redistribution of species, it would be giving caged lemurs a better life- with the human intervention part still intact to monitor their well-being and their environmental impact. This is good publicity for lemurs to highlight the plight of their natural habitat.It would be great if those with resources were able to protect parts of Madagascar as a National Park. Maybe a convergence of good influences to help Madagascar preserve its unique diversity ,modelled along the same lines as Costa Rica

    and a country?

  • Comment number 34.

    Have just been reading about the history of Madagascar. And Pleistocene extinctions. As might be expected on an island - even one as big as Texas - there were many extinctions, including a whole cast of very large lemurs. So the current problems are the continuation of a longer trend.

  • Comment number 35.

    #28 Geoff,

    Well... still having trouble with your vision of North America as impoverished. Yes, there were a lot of Pliestocene species lost when humans arrived.

    But that is not particularly relevant to what has happened in the last 10,000 years, except as something to learn from. We could go back further and note all the extinct dinosaurs.

    But on the other hand... elk, moose, brown bears, wolves, are Eurasian species which moved to southern North America after the ice melted. So...

    Indeed, if you add all the new species that have come to North America - everything from honeybees to earthworms to Chukar partridges - there is far more biodiversity now. Yes, those species have brought ecological changes, some good and some bad, but that has always been the way of the world. Change is the only constant.

    The black bear has been in North America for about 3 million years. It did survive. But the inconvenient truth is that there are now more black bears in North America than there have been at any time in hiostory or probably prehistory. All of their eastern US range was occupied by either farmers or hunter-gatherers... and if you think black bears are a 'problem' for people now, there were much more of a problem for those people. They were also a prime source of fat, fur and meat.

    So now there are more. Why? Because we are wealthy enough NOT to need to kill them or directly compete with them. Conservation is a luxury and a function of wealth. That is very evident in the real world.

    And more on your perceptions of impoverished North America. If that was true, where are all the (recently) extinct species? Eight birds in all of recorded history, none since the passenger pigeon a century ago (although they more recently sort of announced the extinction of the Eskimo curlew... but it was actually gone, or on the verge a century ago). Mammals? Please. Name one.

    Given what has happened here over the past 200+ years, I would say that that is a great record. And it started getting better 100 years ago when there was a real extinction crisis in North America, mostly due to overhunting (market hunting).

    I think it would be great if some sort of "legal stewardship" could be bought (rather than the land itself) in which the "steward" had a legal and publicly-accountable responsibility of maintaining its biological/ecological value.

    I've had it up to here with super-colossal billionaires such as Sting, Bono and Richard Branson making yet more mega-bucks out of telling the rest of us how we should behave. Let US tell THEM how THEY should behave. Let's tell them: If you care about the rainforests, or lemurs, Sting et al, put your big fat money where your big loud mouth is, and do some genuine good for a change instead of flashing your holiness around the place.

    I understood the 24 ring tailed (hardly the most endangered of the 60 taxa) lemurs were going from Western zoos?
    Making a much different issue from the implied one of saving Madagascars lemurs.
    Saving lemurs ace brilliant a wonderful sentiment which I would applaud.
    What about indigineous fauna, they will get eaten, is there anything which will predate the lemurs and what the lemurs will predate has to be investigated thoroughly first. Never forget what happened with the rosy wolf snail, the giant african snail and the partual snail in Polynesia (google it). Saving the lemurs is something I would love to happen but it is not a solution if there is a possibility of putting another species in danger which may or may not be the case.

  • Comment number 39.

    I am wondering whether Sir Richard Branson might consider buying up a suitable area of degraded former forest land in Madagascar; then working with those of us who are trying to address the underlying causes of the deforestation; together with long-term protection of the habitat for these lemurs and all the other interconnected organisms there.
    Food-insecurity is a massive driver of this problem. There are now viable answers to it. Removing this source of pressure will allow the ecosystem to recover slowly...and it can be aided by active reforestation, where practical and affordable.
    RBG Kew and Inga Foundation have begun working jointly on this.

  • Comment number 40.

    No. 23, 39 et al.
    This is exactly the point - buying parts of Madagascar to protect them won't work in the current socio-political situation. So Branson is saying should we just try protecting these species somewhere else.
    There are many protected areas around the world which are failing to protect the species within them.
    Even if we disagree with Branson's project, at least he has highlighted the failings in Madagascar.

    Oh, and as for everyone saying the introduction of species is always a disaster, might I point out the rabbit?

    I have to disagree with this:

    "responsible societies choose to limit their numbers"

    The trouble is, individuals make decisions, not societies. The societies in which individuals limit their numbers are not "responsible societies" so much as "societies in which it is advantageous for individuals to limit their reproduction". These are generally affluent societies in which parents don't have to worry about the high attrition rate of children, or the necessity for siblings to look after each other if parents die, or the life-threatening privations of old age if they are lucky enough not to die.

    In societies where those are real concerns, responsible individuals do the responsible thing by having more children.

    Let's all be as aware that life in places like Madagascar is different from life in the affluent West. Our concerns about over-population and lemurs are a sort of luxury that they cannot afford.

    Indeed. I was just thinking about this concept. Here's a simple way of thinking about it.

    Madagascar is an island. The UK is an island(s).

    If somehow there was such a thing as British lemurs, and they had some how survived to 2011, I wouldn't be too worried about them. Their populations would probably be very secure and possibly thriving.

    So what's the difference between the UK and Madagascar? The UK has a much higher population density... more intensive land use...

    Another example. All the deer in North American suburbia... and in the UK now too I hear. They wouldn't survive around people who were not so wealthy. They would be eaten.

    So to save things in Madagascar, that country needs economic development to make those people more affluent. The rest falls into place from that.

    Judge it for yourself: if you have one child, it is more likely to die than live. If you have two children, you are more likely to have a child that can look after you in old age (i.e. the equivalent of a pension plan). If you have three children, the children who do not die can act as parents to those whose parent do die.

    Before the Romans, there were no rabbits outside Spain. Hares, certainly, but no rabbits. In fact, Spain is actually named after the rabbit. The Phoenician settlers found rabbits in abundance, and mistook them for hyraxes of Africa; thus they named the land in their Canaanite dialect. The Latin-speaking Romans adapted the name as Hispania. The Latin name was altered among the Romance languages, and entered English from Norman French as Spagne.

    As for the killer rabbit, The Holy Hand Grenade of Antioch took care of the last of those.

    Lamna nasus @ 50,

    Malthusian land-inheritances in Africa have been the cause of genocides more than a few times.

    My 'favourite' research study is within the context of the Ruandan genocide - André & Platteau; Land Relations Under Unbearable Stress: Ruanda Caught In The Malthusian Trap (1998).

    This study of the Kanama commune identified the way by which inheritance made starvation, poverty and ultimately murder 'inevitable'. And, whilst Malthusian outcomes are NOT inevitable, this case study shows the terrible track to self-destruction built in to this socially fixed pattern of inheritance.

    The study also showed that the killings were not simply Tutsi-Hutu tribal, but that many Tutsi-Tutsi and Hutu-Hutu land issues were sorted out with the machete under the cloak of tribalism.

    So Lamna nasus is 'spot on'.

Perhaps he will be amenable to supporting more practical projects for the protection of lemurs and lemur habitat.

    Lets see, the population of Madagascar is growing at about 3% per year. That means doubling every ~23 years. Just how much longer do you think this ponzi scheme will last in an effort to provide care for the aged? I thought you said you and gone through integral calculus in your studies. You should be able to look at the implications of this state of affairs. Why don't you calculate how long it will take to get to 1 person per sq. meter.

    re: 55 GeoffWard

    Malthusian land-inheritances in Africa have been the cause of genocides more than a few times.

    And were one driver of the Crusades. So long as wealth is primarily tied to land, the problem is endemic. Hence the beauty of capitalism, which, among many other things, shifts the focus of value from land to labour.

    The upshot being, it is through economic growth that the Malthusian problem may be solved.

    Or at least it is in principle.

    For anyone interested in the population question, and particularly the population question in Africa, I suggest this little essay.

    It makes several interesting points, noting that, in Kenya at least, population growth these days stems not from increasing fertility levels, but from increasing life expectancy and the echo of the initial population boom. He also notes that population densities in sub Saharan Africa remain well below those of Western Europe.

    The point being, can we really expect Africa should forever remain an agrarian backwater, a game preserve for urban First Worlders, forever?

    What an utterly naive induction, one that completely ignores the factors that cause populations to increase or decrease. You're simply looking at a pattern and extrapolating from it. It's like saying that in a few decades we'll have skyscrapers that extend into space.

    "Just how much longer do you think this ponzi scheme will last in an effort to provide care for the aged?"

    The extended family is a central part of human evolution, so it's been a "normal" human pattern for at least 50,000 years. You'll find that reproduction itself has been around even longer. That's why there are so many rabbits, have you noticed?

    Instead of complacently wagging your moralistic Western finger, I suggest you give a moment's thought to what motivates people to have more children.

    So you could say that we can blame the Romans for giving us "Night of the Lepus" 1972.

    Cole Hillman's Arizona ranch is plagued with 'mongrel' rabbits, and he wants to employ an ecologically sound control method. As a favor to college benefactor Hillman, college president Elgin Clark calls in zoologist Roy Bennett to help. Bennett immediately begins injecting rabbits with hormones and genetically mutated blood in an effort to develop a method of disrupting rabbit reproduction. One of the test subjects escapes, resulting in a race of bloodthirsty, wolf-sized, man-, horse-, and cow-eating bunnies. Eventually the National Guard is called in for a final showdown with the terrorising rabbits.

We've been seeing them wandering around more and more often recently and what with all of the traffic in our little commuter enclave, the occasional dead one on the side of the road too. But there really is a surprising amount of wildlife in and around where we live and I've been noticing a general increase in the bird, rabbit and fox populations too.

    It seems that as all of the construction companies have moved out, so the animal populations have moved back in and apparently started to thrive - It's quite encouraging really.

    @Others

    Getting back to the topic of Madagascar, I guess the key is sustainability of use and the viability of isolated populations. More protected areas need to be established and some land could be returned to the wild or fruit plantations. There's been some work done on establishing corridors, somewhat akin to a British hedgerow between protected areas, but on a much, much grander scale, see:

    https://www.conservation.org/learn/climate/forests/Pages/project_mantadia.aspx

    Whilst, the organisation in question and myself, disagree on some quite fundamental issues (climate change for instance) we do agree on a lot more re: changes in land use and habitat protection etc etc. By closely involving the local populations and providing them with access to better land and forestry management techniques they are providing them with both jobs and access to sustainable forestry resources.

    All in all, and given where we are (approx 10% of Madagascan rain forest remaining) these sorts of schemes have to be the best way forwards.

    With regards to the apparent slightly colonial/genocidal tendancies that are being expressed by some of our contributors, I’m afraid you’re on your own with all of that, it really beggars belief that people can even contemplate those sorts of things….

    I think they were right to try to convert people away from black magic, ritual murder, etc.. But you can only implant values by appealing to more basic values that people already have -- such as commitments to truth and decency.

    Suppose some missionaries came here and tried to convert us away from testing on animals. We would argue that human health is more important than the animals' well-being. They would have to appeal to values we already have -- such as kindness and the elimination of fear and pain -- to persuade us. Because we are already doing what we think is best by our own lights.

    Many people who have a lot of children are already doing "the responsible thing" by their own lights because in the absence of social welfare, health care, etc., they are in effect getting "insurance" by other means.

    Rather than forcing them to use birth control which they would regard as irresponsible, or hoping to brainwash them into thinking it's in their interest when it isn't, perhaps we should enable them to improve their expectations so that having fewer children really is in their own interest (rather than our interest).

    africa will develop economically because they have huge resources and the chinese need them. it is becoming common for the chinese to swap access to resources for huge investment in infrastructure projects (mostly with chinese workers though).

    Indeed. It has little to do with habitat other than maintaining some. It is all about a change in attitudes which is made possible by affluence. Without the latter the suburbanites would be eating the deer. Classic example of the difference between the UK and Madagascar.

    The problem with this, as you folks in the UK will discover if it is not already evident, is that those deer populations are going to explode and that overpopulation will have major and destructive impacts on the shrubbery they browse down, which will have major impacts on habiat for other species - most conspicuously songbirds.

    In the eastern US in particular there are areas which are becoming ecological basket cases because of deer overpopulation... but the uninformed and ecologically ignorant public is so in love with their bambis that they go ballistic when any controls are suggested.

    Just as too few of a species is a problem, so is too many. All Greens seem to understand that when it comes to people but don't get that point when it comes to deer or many other things.

    By the way, I keep seeing rumours of some grand plan to reintroduce wolves to the UK... perhaps as a means to address deer or red deer (elk as we call them) populations. In a place like the UK that would be absolutely insane. As a test, just let a few packs of wild dogs roam free for a while and see how that works out... because wolves and dogs are the same species and when dogs are in packs they go wolfish. Much simpler and better to increase human hunting... but that brings us back to the uninformed ecologically ignorant sentimental anti-hunting crowd that won't let that happen. They must secretly hate deer if they would prefer to see them starve to death or be ripped apart by wolves rather than killed quickly.

    You do manage to miss the point, no doubt intentionally. The little calculation I suggested you undertake was to point out that, in time, there will be a change whether or not it is desirable from a cultural point of view. The question is, is it better to let nature and culture take its course and turn the whole island (or whole planet) into a waste land, or try and apply a little human intelligence to anticipate the consequences of continuing down the current path and try and change things before "nature" does it for us the old fashion way.

    If organisms breed like rabbits, they end up dying like rabbits, because that planet will not accommodate infinite growth of anything real. Or to paraphrase Kennith Boulding, if you believe in infinite growth on a finite planet you are either a fool or an economist.

    You also seem to have a consistency problem, on the one hand you accuse middle class people who point out the obvious, i.e. that the population of Madagascar will not be able to sustain a 3% growth rate for very long, with moralizing, yet you claim to support spreading "humanitarian" beliefs that would lead Africans away from killing and dismembering albino's as part of the cultural traditions.

    I was under the impression it was a deduction: i.e. I look at the land area of Madagascar, the current population estimate and the current growth rate. I calculate how long it would take to get to one person per sq. meter. I realize that the probability of arriving at this state is close to zero and therefore conclude, either the culture will change dramatically to choosing smaller families, or the death rate will rise dramatically or there will be massive emigration to places that already have no shortage of people. It is really just a matter of arithmetic. So which alternative is your preference?
