Pastoral Icon or Woolly Menace?

by Richard Coniff

You don’t have to look far to see the woolly influence of sheep on our cultural lives. They turn up as symbols of peace and a vaguely remembered pastoral way of life in our poetry, our art and our Christmas pageants. Wolves also rank high among our cultural icons, usually in connection with the words “big” and “bad.” And yet there is now a debate underway about substituting the wolf for the sheep on the (also iconic) green hills of Britain.

The British author and environmental polemicist George Monbiot has largely instigated the anti-sheep campaign, which builds on a broader “rewilding” movement to bring native species back to Europe. Until he recently relocated, Mr. Monbiot used to look up at the bare hills above his house in Machynlleth, Wales, and seethe at what Lord Tennyson lovingly called “the livelong bleat / Of the thick-fleeced sheep.” Because of overgrazing by sheep, he says, the deforested uplands, including a national park, looked “like the aftermath of a nuclear winter.”

“I have an unhealthy obsession with sheep,” Mr. Monbiot admits, in his book “Feral.” “I hate them.” In a chapter titled “Sheepwrecked,” he calls sheep a “white plague” and “a slow-burning ecological disaster, which has done more damage to the living systems of this country than either climate change or industrial pollution.”

The thought of all those sheep — more than 30 million nationwide — makes Mr. Monbiot a little crazy. But to be fair, sheep seem to lead us all beyond the realm of logic. The nibbled landscape that he denounces as “a bowling green with contours” is beloved by the British public. Visitors (including this writer, otherwise a wildlife advocate) tend to feel the same when they hike the hills and imagine they are still looking out on William Blake’s “green and pleasant land.” Even British conservationists, who routinely scold other countries for letting livestock graze in their national parks, somehow fail to notice that Britain’s national parks are overrun with sheep.

Mr. Monbiot detects “a kind of cultural cringe” that keeps people from criticizing sheep farming. (In part, he blames children’s books for clouding vulnerable minds with idyllic ideas about farming.) Sheep have “become a symbol of nationhood, an emblem almost as sacred as Agnus Dei, the Lamb of God,” he writes. Much of the nation tunes in ritually on Sunday nights to BBC television’s “Countryfile,” a show about rural issues, which he characterizes as an escapist modern counterpart to pastoral poetry. “If it were any keener on sheep,” he says, “it would be illegal.”

The many friends of British sheep have not yet called for burning Mr. Monbiot at the stake. But they have protested. “Without our uplands, we wouldn’t have a UK sheep industry,” Phil Bicknell, an economist for the National Farmers Union pointed out. “Farmgate sales of lamb are worth over £1bn” — or $1.7 billion — “to U.K. agriculture.” The only wolves he wanted to hear about were his own Wolverhampton Wanderers Football Club. A critic for The Guardian, where Mr. Monbiot contributes a column, linked the argument against sheep, rather unfairly, to anti-immigrant nativists, adding “sheep have been here a damn sight longer than Saxons.”

Mr. Monbiot acknowledges the antiquity of sheep-keeping in Britain. But the subjugation of the uplands by sheep, he says, only really got going around the 17th century, as the landlords enclosed the countryside, evicted poor farmers, and cleared away the forests from the hillsides and moorlands, particularly in Scotland. Britain is, he writes, inexplicably choosing “to preserve a 17th-century cataclysm.” The sheep wouldn’t be in the uplands at all, he adds, without annual taxpayer subsidies, which average £53,000 per farm in Wales.

He proposes an end to this artificial foundation for the “agricultural hegemony,” to be replaced by a more lucrative economy of walking and wildlife-based activities. He also argues for bringing wolves back to Britain, for reasons both scientific (“to reintroduce the complexity and trophic diversity in which our ecosystems are lacking”) and romantic (wolves are “inhabitants of the more passionate world against which we have locked our doors”). But he acknowledges that it would be foolish to force rewilding on the public. “If it happens, it should be done with the consent and active engagement of the people who live on and benefit from the land.”

Elsewhere in Europe, the sheep are in full bleating retreat, and the wolves are resurgent. Shepherds and small farmers are abandoning marginal land at an annual rate of roughly a million hectares, or nearly 4,000 square miles, according to Wouter Helmer, co-founder of the group Rewilding Europe. That’s half a Massachusetts every year left open for the recovery of native species.

Wolves returned to Germany around 1998, and they have been spotted recently in the border areas of Belgium, the Netherlands and Denmark. In France, the sheep in a farming region just over two hours from Paris suffered at least 22 reported wolf attacks last year. But environmentalists there say farmers would do better protesting against dogs, which they say kill 100,000 sheep annually. Wolves are now a protected species across Europe, where their population quadrupled after the 1970s. Today an estimated 11,500 wolves roam there.

Lynx, golden jackals, European bison, moose, Alpine ibex and even wolverines have also rebounded, according to a recent study commissioned by Rewilding Europe. Mr. Helmer says his group aims to develop ecotourism on an African safari model, with former shepherds finding new employment as guides. That may sound naïve. But he sees rewilding as a realistic way to prosper as the European landscape develops along binary lines, with urbanized areas and intensive agriculture on one side and wildlife habitat with ecotourism on the other.

In northern Scotland, Paul Lister is working on an ecotourism scheme to bring back wolves and bears on his Alladale Wilderness Reserve, where he has already planted more than 800,000 native trees. He still needs government permission to keep predators on a proposed 50,000-acre fenced landscape. That’s a long way from introducing them to the wild, on the model of Yellowstone National Park. Even so, precedent suggests that it will be a battle.

Though beavers are neither big nor bad, a recent trial program to reintroduce them to the British countryside caused furious public protest. (One writer denounced “the emotion-based obsession with furry mammals of the whiskery type.”) And late last year, when five wolves escaped from the Colchester Zoo, authorities quickly shot two of them dead. A police helicopter was deployed to hunt and kill another, and a fourth was recaptured. Prudently, the fifth wolf slunk back into its cage, defeated.

Rewilding? At least for now, Britain once again stands alone (well, alone with its 30 million sheep) against the rising European tide.

Montana’s Glaciated Plains: Thinking Big Across Time and Space

Posted by Sean Gerrity of American Prairie Reserve, National Geographic Fellow on November 2, 2012 

American Prairie Reserve’s mission to create a reserve of more than three million acres represents one of the largest conservation projects in the United States today. The size of the project is hard to grasp – even a small piece of the 274,000 acres that currently comprise the Reserve seems like an endless “sea of grass” to both first-time and seasoned visitors. However, after ten weeks of research on historical wildlife populations of Montana’s glaciated plains, I have become increasingly convinced that APR’s vision is necessary. If we want to understand the behavior and ecology of grassland species, we need to think big.

America’s iconic species – bison, pronghorn, elk, wolves, grizzly bears – evolved over tens of thousands of years on a wide-open continent. Over this long period of time, these species became well adapted to environmental “stochasticity,” the highly dynamic and unpredictable nature of their habitat. In fact, the prairie is one of the most dynamic ecosystems in the world.

Settlers came to Montana in the early 20th century after being told that if they turned the soil they could transform the rugged landscape and cultivate a fertile Eden. A few years of unusually (and well-timed) wet conditions in the 1910′s bolstered this belief, but a severe drought in the 1920′s caused devastation for most agricultural producers. Unlike its settlers, though, the region’s wildlife had evolved several adaptations to deal with these rapid and extreme fluctuations. It turns out that the key to persistence in a highly stochastic environment is to employ a range of survival techniques.

On a wide-open continent, ungulates like elk, deer and pronghorn thrived in many different habitats and were able to chose from a toolkit of survival strategies grounded in their history and experience on the land. If conditions were optimal, herds would be inclined to stay put, but in periods of high environmental variance, they would have had to choose a new strategy. For instance, when temperatures dropped abnormally low, ungulates fled the prairie and sought thermal refuge in the Missouri River Breaks or the Rocky Mountains.

Through my research, I also discovered the debate over whether bison were historically a migratory or a nomadic species. Did they follow specific migratory patterns, or did they move in a sporadic, localized manner related to the availability of food? We’re not sure, but the truth is probably somewhere in the middle. Regardless, much of the migratory behavior that we observe in terrestrial species today is shaped by human intervention. We have severely restricted the habitats of most wildlife species, and climate change threatens what marginal areas remain.

Recent studies predict that changes in climate, such as increases in severe weather events and changes in precipitation levels, will affect grassland ecosystems, from native plant and weed distribution to altered fire regimes. Conservation planners will have to react to these to the best of their ability within the limits of science, funds, and space.

For the ungulate species that American Prairie Reserve (APR) is trying to recover, bigger is better. A large reserve would allow wildlife to utilize more of the strategies in their survival toolbox. It may also be able to buffer the adverse effects of climate change by encompassing more habitat niches and providing more space for wildlife to disperse while still remaining within reserve boundaries. Furthermore, a large area has the capacity to support higher numbers of wildlife, which greatly reduces the risk of a population extinction event.

American Prairie Reserve recently celebrated the acquisition of a 150,000-acre property that more than doubled the size of previous habitat and added 16 miles of shared border with the 1.1 million-acre Charles M. Russell National Wildlife Refuge. Even though the goal of APR seems very ambitious at times, we must remember that wildlife persisted on a much larger landscape for thousands of years before Lewis and Clark ever walked on this land.

Thus, it is a mistake to conceptually box these species into a specific habitat-type or set of behaviors. As Lewis put it, the historical American West contained “immence herds of Buffaloe, Elk, deer and antelopes feeding in one common and boundless pasture.” While we will never be able to recapture the full picture of historical wildlife on the frontier, American Prairie Reserve can reestablish a pretty big chunk of that natural legacy.

Ghosts of the Appalachians or the Missing Actors?

 When we pass through the Appalachian Mountains along its vast extent from the humid southeast of Alabama and Georgia to the cold and barren of Nova Scotia and Newfoundland, we cannot help but marvel of its beauty and extensiveness.  Unlike its western cousin, the Rocky Mountains, which is a mixture of forested ranges imbedded in a matrix of lowland shrub and grass ecosystems, the Appalachians are heavily forested mountains imbedded in what is likely one of the largest forest ecosystems in the world.  One can only imagine the extensiveness of the original eastern forest, extending to the north as far as the tundra, to the south to the Gulf of Mexico and to the west until the beginning of the Great Plains.  It is this eastern “endless” forest that provided the opportunities and resources to the Earlier Americans who lived there for centuries.  It is also this bountiful forest that gave the European explorers who followed their toehold on the continent.  Rich in plant and wildlife resources, the eastern forest likely had one of the highest densities of Earlier Americans in North America.  Even today, the eastern forest continues to support the highest density of Current Americans.

Much has been written about the destruction of the eastern forests by early European colonists and their descendants.  However, today past abuses and scars of these earlier settlers have been covered over by an extensive mantel of young and thriving forest mixed in with verdant farmland.  In fact, the structure of the current forest ecosystem of the east is probably much like that before Europeans arrived, a mixture of open farmland and dense forest. Today, as in those earlier times, the open farmland provides areas of high productivity where many species of wildlife can find food while the forest provides shelter from the elements.


    To the viewer’s eye, it would seem that the eastern forests, especially the Appalachian Mountains, have returned to much of their former beauty and glory.  Even in the more populated areas of the East, the forest extends its fingers into the fringes of the cities.  It is only in the East that abandoned land quickly reverts to forest!  In these extensive forests all along the eastern seaboard, abundant wildlife, small song birds and mammals, larger turkeys, hawks, and even larger deer and bear, are again abundant in many parts of the Appalachian chain.  Though much was lost in the past, the recuperation of the eastern forest ecosystem throughout the eastern seaboard makes it a true success story, a paradise gained!  All this in light of one of the highest human densities in North America!

    But has the Eastern Forest truly returned to its past glory as an ecosystem?  An ecosystem is not like a museum, not just a static collection of parts, plants and animals.  It is a dynamic entity, one that constantly changes, grows, dies. All its parts have a function, a function vital to the health of the ecosystem.  The plants of an ecosystem function as extensive solar traps, each day, month, year, capturing immense amounts of solar energy.  That energy is transferred along to other parts of the ecosystem in a cascading chain of actions reaching the smallest corners, maintaining the diversity of life found there.  In each step, energy is transferred, energy is lost.  Eventually that energy passes out of the ecosystem, replaced by new waves of solar radiation.  In a true sense, the function of an ecosystem is this transfer of solar energy from one component to the next.  It is this energy transfer that keeps the ecosystem “alive”, maintaining its integrity and its diversity.
    The role, then, of plants and animals in the ecosystem is in successfully performing this transfer.  This is no small task and like an elaborate play, is accomplished by a well choreographed cast of thousands, of millions, playing parts honed by millennia of co-evolution.  All this is carried out on the stage of the ecosystem, the physical, the biological props and scenery that we see.  For most of the players in this production, theirs is a dual role, they capture that energy and pass it on to others.  They are both consumer and consumed, predator and prey.  Half of the ecologically important role of prey is to be eaten by their predators.  In doing so, they pass their energy on to the next step, fulfilling their ecological mission. How this is all done is the intrigues, the sinuous plots of this elaborate play.  At each step, the predators, take the energy to the next level. Many of these predators, in turn, have their own predators, fulfilling their dual role.  That is how the system works. In each step, energy is transferred, energy escapes, leaving less energy for the next consumer, the next predator.
    What is that final passage of energy within the system?  Who are the ultimate or “top” consumers/predators?  It is the largest predators, the Wolves, the Cougars, the Lions, animals that normally don’t have another predator trying to eat them.  The remaining energy that reaches them passes through their bodies, leaving the system.  These top predators, then become the critical, the climax actors in the final act of this ecological play.  It is through them this energy, initially captured by plants from the sun, flows, completing its run, its final curtain call. However, it is a never ending final call, a never ending play as new energy continues moving up, new prey, new predators, new actors, providing life, vitality, diversity to the stage of the ecosystem, the play of life.
    What happens if these top actors are missing?  Can the play go on?  Can a system fine tuned over evolutionary time whose function depends on each part being connected, continue to work in the absence of its climax actors?  We have ample evidence that suggests not.  Predators in general and large ones in particular, have always bore the brunt of humans’ dislike and scorn.  Viewed as villains rather than stars in the play of life, they have always been the first to be removed from the stage.  This has happened not only in the Eastern forests but in most ecosystems in the world.  What has happened in these ecological plays when the top actors have been removed?  Without predators, the energy flow become blocked and can no longer flow upward.  The blockage of this energy flow, as with the blockage of a river or of any flow-through system, the flow backs up, disrupting the system, the ecosystem.  It concentrates in the form of excess numbers of consumers, normally prey for higher levels, and it builds up.  Like a volcano building up pressure and eventually exploding in a series of violent eruptions, destroying the mountain, increasing consumers destroy the ecosystem.  In Yellowstone National Park, removal of the Wolf led to an over population of Elk, leading to losses of plant species Elk preferred, to losses of other species dependent on these plants,  to eventual losses of Elk who starved and died under their own population weight.  Yellowstone changed from a smooth flowing river of energy to one of fits and starts, of energy blockage, a system of violent cycles.  This pattern has repeated itself many times over, the Kaibab plateau after the removal of Cougars, the Moose on Isle Royale, introduced without their predator, the Wolf.  To remove the top predators in these ecosystems was an ecological crime, committing these systems to a slow agonizing death.
    How about the Appalachian forests?  Is the cast of ecological players complete? Unfortunately, the East is also missing its star performers, Wolves and Cougars, having been long killed out by our well-meaning but misguided ancestors.  All that remains are the ghosts of these past performers, apparitions that seemingly appear periodically but are of little substance.  Regardless of all these ghostly sightings, real or otherwise, the cold fact remains, the Wolf and Cougar are ecologically extinct in the Appalachians.  In the absence of these actors, the stage is set for a different script.  Without Wolves and Cougars, their main prey, White-tailed Deer, have returned with a vengeance, in many eastern states numbering in hundreds of thousands to millions of animals.  Each of these individuals ravenously eat around 1,500 pounds of plants per year.  As a result, the eastern ecosystems are time bombs waiting to explode.  Some have already; after years of excessively high deer densities, forest flowers and animals dependent on them are disappearing.  As importantly, tree seedlings, the forest of the future, are also vanishing under the constant chewing of millions of deer.  The ecological fabric of the Appalachian ecosystem is unweaving before our very eyes.  What we see in the verdant, seemingly vibrant forests is a façade hiding a rapidly decaying stage of life, burdened by too many prima donnas.  What we see is not an endless play of life but a short-lived tragedy doomed to failure.
    The fact is clear, the Appalachian play is missing its star performers and an ecological disaster is unfolding on the stage.  Can the ending of this play be changed by bringing back the stars?  Can it be as simple as that? Scientifically, the answer is a resounding yes.  However, before society agrees, many questions need to be answered.  The first of which is: can Wolves and Cougars still survive on the modern stage that is the Appalachians of today?  If so, what are some of the dangers, if any, of them coming back.  After all, aren’t they large and dangerous animals???  If we agree that they should come back, how do we as a society help them back?  These and many more questions I hope to address in future posts to this blog.

I was born and raised in the Midwest (Wisconsin) and received my bachelors and masters degrees there.  I received my PhD from Idaho State University in 1979.  Since then, I have been working in large mammal predator-prey ecology for over 30 years and have studied predators and their prey in the western U.S. and northern Mexico.  My experience includes working with cougars, wolves, coyotes, bobcats, deer, elk, bison, and bighorn sheep.  I have conducted one of the longest (17 years) studies of cougar ecology and behavior to date and have published over 15 scientific articles both on this work and work conducted in Mexico.  I am the originator of the concept of the landscape of fear that proposed that fear of prey for their predators drives many, if not all ecological processes.  The one important aspect of this concept is that predators become instrumental in maintaining the balance between prey species and their habitat, not so much by killing their prey but affecting how they use the landscape.  I am the author of the newly published book, Phantoms of the Prairie: The Return of Cougars to the Midwest that looks at the phenomenon of cougars actually moving back into the Great Plains region of the U.S.  I am currently living in Upstate New York in Oswego where I am an adjunct faculty member at the SUNY Oswego and also active in issues concerning cougars in the Northeast.  I am the vice president of the Cougar Rewilding Foundation whose goal is the eventual re-establishment of viable cougar populations in the Eastern U.S.
