An echo in the hills!

Patterns in the ether.

On Monday and Tuesday of the week I posted Legitimate Anger and Legitimate Hope.  (And please see the footnote to today’s post)

Patrice Ayme left the following comment to the Legitimate Hope post:

It’s hard to live with elephants, especially in poor, crowded conditions. I remember bathing in Africa as a child with a bull elephant 200 meters away, on the other side of a stream, and being extremely worried, with all in attendance.

Europe used to have elephants, and North America, two species. Time to reintroduce them, and live according to our discourse.

Rewilding Euramerica can be done, and should be done, for the deepest philosophical and emotional reasons, and will create new, very productive jobs.

Then on Friday came an email from reader and blogger Martin Lack:

Hi Paul,
I saw this on The Conversation website – ‘Restore large carnivores to save struggling ecosystems’ (by Oregon State University’s Prof. William Ripple ) –  and thought of you.

It was but a moment to go across to The Conversation website (rather liked what I saw, by the way) and find the article that Martin linked to. It is republished here within the terms of The Conversation site.


Restore large carnivores to save struggling ecosystems

By William Ripple, Oregon State University
We are losing our large carnivores. In ecosystems around the world, the decline of large predators such as lions, bears, dingoes, wolves, and otters is changing landscapes, from the tropics to the Arctic. Habitat loss, persecution by humans and loss of prey have combined to inflict great losses on these populations.

In fact more than 75% of the 31 largest carnivore species are declining, and 17 species now occupy less than half their former ranges. Southeast Asia, southern and East Africa, and the Amazon are among areas in which multiple large carnivore species are declining. And with only a few exceptions, large carnivores have already been exterminated from much of the developed world, including areas of Western Europe, and the eastern United States.

Top dogs keep ecosystems in order

Many of these large carnivore species are endangered and some are at risk of extinction, either in specific regions or entirely. Ironically, they are vanishing just as we are learning about their important ecological effects, which is what led us to write a new paper in the journal Science to document their role.

From a review of published reports, we singled out seven species that have been studied for their important ecological role and widespread effects, known as trophic cascades. These are the African lion, leopard, Eurasian lynx, cougar, gray wolf, sea otter and dingo.

Based on field research, my Oregon State University co-author Robert Beschta and I documented the impact of cougars and wolves on the regeneration of forest tree stands and riverside vegetation in Yellowstone and other national parks in western North America. Fewer predators, we found, lead to an increase in browsing animals such as deer and elk. More browsing disrupts vegetation, reduces birds and some mammals and changes other parts of the ecosystem. From the actions of the top predator, widespread impacts cascade down the food chain.

Similar effects were found in studies of Eurasian lynx, dingoes, lions and sea otters. For example in Europe, absence of lynx has been closely tied to the abundance of roe deer, red fox and hare. In Australia, the construction of a 3,400-mile dingo-proof fence has enabled scientists to study ecosystems with and without dingoes which are closely related to gray wolves. They found that dingoes control populations of herbivores and exotic red foxes. The suppression of these species by dingoes reduces predation pressure, benefiting plants and smaller native prey.

In some parts of Africa, the decrease of lions and leopards has coincided with a dramatic increase in olive baboons, which threaten crops and livestock. In the waters off southeast Alaska, a decline in sea otters through killer whale predation has led to a rise in sea urchins and loss of kelp beds.

Predators are integral, not expendable

We are now obtaining a deeper appreciation of the impact of large carnivores on ecosystems, a view that can be traced back to the work of landmark ecologist Aldo Leopold. The perception that predators are harmful and deplete fish and wildlife is outdated. Many scientists and wildlife managers now recognise the growing evidence of carnivores’ complex role in ecosystems, and their social and economic benefits. Leopold recognised these relationships, but his observations were ignored for decades after his death in 1948.

Human tolerance of these species is the major issue. Most would agree these animals have an intrinsic right to exist, but additionally they provide economic and ecological services that people value. Among the services documented in other studies are carbon sequestration, restoration of riverside ecosystems, biodiversity and disease control. For example, wolves may limit large herbivore populations, thus decreasing browsing on young trees that sequester carbon when they escape browsing and grow taller. Where large carnivore populations have been restored – such as wolves in Yellowstone or Eurasian lynx in Finland – ecosystems appear to be bouncing back.

I am impressed with how resilient the Yellowstone ecosystem is, and while ecosystem restoration isn’t happening quickly everywhere in this park, it has started. In some cases where vegetation loss has led to soil erosion, for example, full restoration may not be possible in the near term. What is certain is that ecosystems and the elements of them are highly interconnected. The work at Yellowstone and other places shows how species affect each another through different pathways. It’s humbling as a scientist to witness this interconnectedness of nature.

My co-authors and I have called for an international initiative to conserve large carnivores in co-existence with people. This effort could be modelled after a couple of other successful efforts including the Large Carnivore Initiative for Europe, a non-profit scientific group affiliated with the International Union for the Conservation of Nature, and the Global Tiger Initiative which involves all 13 of the tiger-range countries. With more tolerance by humans, we might be able to avoid extinctions. The world would be a scary place without these predators.

Footnote – Please help the elephants

Tuesday’s Legitimate Hope included this:

Also what needs to be highlighted are the organisations that are actively working on behalf of the elephants.

The Independent Newspaper have their own elephant campaign.

Elephant Crisis

In 2011, more African elephants were killed than any other year in history. The figures for 2012 and 2013 are not yet known, but are likely to be even higher. At current rates, in twelve years, there will be none left.

It is a familiar cause, but it has never been more urgent. Poaching has turned industrial. Armed militia fly in helicopters over jungle clearings, machine gunning down entire herds. Their tusks are then sold to fund war and terrorism throughout the continent and the wider world. Ivory is still illegal, but as China booms, it is more popular than ever.

This campaign will raise money to support rangers on the ground to protect Kenya’s elephants from armed poachers, together with Space for Giants’ longer term work to create new wildlife sanctuaries where elephants will be safe, forever. More can be found about the charity at Space for Giants

The article above includes two videos.  A shorter one that can be viewed on the paper’s campaign website. Then there is a longer, five-minute, video also on YouTube and included below.

Offering a donation to help is only a click away.

Jean and I wanted to make a donation but found that without a UK bank account/UK Visa card it wasn’t possible.  We contacted Space for Giants and received the following email from Amy.


Hi Paul

Sorry for the difficulties and thank you for your perseverance!
You can donate in USD through our CrowdRise page at These funds are sent to TUSK USA who will then allocate them to us.
Alternatively, you can make out a cheque to ‘TUSK USA’  and send to TUSK USA, 40 East 94th Street, Apt 3A, New York, NY 10128 – please attach a covering note confirming that you would like your donation to be used to support the work of Space for Giants.
Many thanks,
So if there’s anyone else out there not in the UK who would like to donate, here’s another option.
Please, for all our sakes, help these beautiful creatures.

  1. Paul, let me piggy back on this in my own way

    Restore the access to bank credit to our small carnivorous risk-takers in order to save the ecosystem of our economy!

    Currently the capital requirements for banks, instead of being based on “unexpected losses”, which is what bank capital is there to cover for, are based on the same perceived risks used to estimate the “expected losses”

    Think about it! Where do you believe the kind of unexpected losses that could bring down the banking system could really come from… the “absolutely safe” or the “risky”.

    And that double counting of “perceived risk” has translated, by means of risk-weighting, into favoring the “infallible sovereign” and the AAAristocracy, and odiously discriminating against the “risky”, the medium and small businesses, entrepreneurs and start-ups.

    And the regulators do not even understand what they are up to… and much less are they doing anything about it.


  2. Item published on the BBC News website two days ago:

    More than three quarters of large carnivores now in decline

    Three quarters of the world’s big carnivores – including lions, wolves and bears – are in decline, says a new study.

    A majority now occupy less than half their former ranges according to data published in the journal, Science.

    The loss of this habitat and prey and persecution by humans has created global hotspots of decline.

    The researchers say the loss of these species could be extremely damaging for ecosystems the world over.


  3. The strange thing is that people are migrating to cities. Moreover, for a number of reasons, including cost, marginal agricultural land is been given up. These are perfect conditions for rewilding. Introduce the Amur leopard and the Siberian tiger to the Yukon (under very close watch), etc.

    Animals such as Aurochs and Wooly Rhinoceroses, if they could be back engineered (Auroch is half way there) would not be difficult to manage. Local prehistoric horses are being reintroduced at the Spain-Portugal border.


    1. @Patrice
      “The strange thing is that people are migrating to cities”

      Not so strange. Cause, meet effect. Cities are far more damaging to the environment than smaller units. (trivial eg think: all those trucks driving in, and out, and in, and out, and in, and out… ad nauseam, emphasis on the nausea)


      1. I actually expressed myself poorly. I did not mean that it was strange to move into cities, but that it was strange not to use the opportunity to rewild.
        “Cities are far more damaging to the environment than smaller units”: many ecologists would disagree. Also cities could be made self sustained with new tech.


      2. Speaking of strange, I’ve just read a George Monbiot essay that describes Government policies in Britain with regard to water management as utter madness. Hope GM will allow me to republish.


  4. Don’t French mega corporations own British water? (Makes sense: frogs ought to know about water, as smart readers of the Wall Street Journal would say….)
