  • Reviews for Richard Conniff’s Books

    Every Creeping Thing: True Tales of Faintly Repulsive Wildlife: “Conniff is a splendid writer–fresh, clear, uncondescending, and with never a false step; one can’t resist quoting him.” (NY Times Book Review)

    The Species Seekers:  Heroes, Fools, and the Mad Pursuit of Life on Earth by Richard Conniff is “a swashbuckling romp” that “brilliantly evokes that just-before Darwin era” (BBC Focus) and “an enduring story bursting at the seams with intriguing, fantastical and disturbing anecdotes” (New Scientist). “This beautifully written book has the verve of an adventure story” (Wall St. Journal)

    Swimming with Piranhas at Feeding Time by Richard Conniff  is “Hilariously informative…This book will remind you why you always wanted to be a naturalist.” (Outside magazine) “Field naturalist Conniff’s animal adventures … are so amusing and full color that they burst right off the page …  a quick and intensely pleasurable read.” (Seed magazine) “Conniff’s poetic accounts of giraffes drifting past like sail boats, and his feeble attempts to educate Vervet monkeys on the wonders of tissue paper will leave your heart and sides aching.  An excellent read.” (BBC Focus magazine)

Why Not Pay Herders to Make Wolves & Wolverines Thrive?

People who kill predators don’t get much sympathy, and they don’t generally deserve any either. But there is an exception: impoverished herders and pastoralists whose animals are being killed by lions, tigers, wolves, or other large carnivores. These people are often caught in a bind: Kill a protected animal and risk fines or imprisonment, or watch their livestock vanish and their families go hungry.

In Sweden, the government has been trying to ease this dilemma with an innovative strategy that aims to encourage coexistence. It rewards herders as local carnivore populations increase—and a new study says it works.

In the Arctic regions of northern Scandinavia, the Sámi people, also known as Lapps or Laplanders, live by herding semi-domestic reindeer. But they share the landscape (and often the reindeer) with wolverines—big, bearlike weasels with ferocious personalities. (Their aggressiveness has made wolverines a popular team mascot, generally among people who have never met one.) To defend their livelihood, Sámi herders often end up killing wolverines, which are a protected species.

The usual remedy to reduce that kind of herder-carnivore conflict—and this is true from Wyoming to Nepal to Australia—is for governments or conservation groups to compensate the herders every time a predator takes one of their animals. But it’s a cumbersome process, usually requiring an on-site inspection, and it frequently does not work. Compensation schemes can also create perverse incentives encouraging herders to neglect their animals, in effect allowing them to be killed. These types of compensation programs also “don’t seem to increase tolerance for the wildlife in question,” said Adrian Treves, founder of the Carnivore Coexistence Lab at the University of Wisconsin–Madison, who was not involved in the new study, “and if you don’t increase tolerance for the wildlife, it’s difficult to reduce poaching.”

So instead of rewarding herders when things go wrong, why not design “conservation performance payments” to reward them when they go right?

That’s the approach in Sweden. Since 2002, herders there have earned extra income every time wolverines are born in their area. The idea is to give the herders an incentive to keep the wolverine population strong, a disincentive to kill them, and some money to replace any reindeer that the wolverines take.

But given the deep and bitter antagonism toward predators, can that sort of scheme work? The new study from the Grimsö Wildlife Research Station in Sweden says yes. Researchers there looked at long-term data from radio-collared wolverines and from a national population-monitoring program.

The study, published online in Conservation Letters, found that poachers have predictably continued to kill some wolverines. But since the new scheme went into effect, they have killed far fewer females than males. The Sámi are not stupid; females are responsible for giving birth to wolverine pups, and compensation is based on those births. But the effect on populations has been substantial. While populations had been slowly increasing since Sweden first protected wolverines in 1969, they began to grow dramatically as a result of the new compensation scheme, up from 57 registered births in 2002 to 125 in 2012.

It’s possible that more males ended up being killed because of differences in behavior between males and females. But the researchers didn’t find any evidence of that. Rather, they concluded that “the lower poaching rate for females is actually an effect of the payment made to the reindeer herding communities,” according to Guillaume Chapron, one of the paper’s coauthors.

But there is a potential hitch, or what scientists call a “confounding factor,” according to Treves. The new compensation scheme required active monitoring of wolverines to determine the number of new litters. So “we’re not actually sure if the payments reduced poaching or if the monitoring and verification reduced poaching,” said Treves. Further studies to sort out those effects would be useful. For now, though, this type of payment appears to work. “Poaching can be reduced,” said Treves, “by a careful application of some sort of monitoring or enforcement as well as an incentive for the poachers or their communities to see value in the endangered species.”

Treves thinks that many endangered carnivores around the world could benefit from the Swedish method of “paying for live carnivores rather than for dead reindeer,” as he put it, from wolves in Wisconsin to lions in Tanzania. Each region would need to tweak the compensation scheme to fit local conditions, but “I don’t think that’s an insurmountable obstacle,” he said.

The livestock-versus-carnivore conflict is an ancient battle, and the carnivores have almost always been on the losing end of the deal, with many now facing extinction in the wild. Altering that deadly dynamic has proved almost impossible up to now. But biological studies over the past few decades have also taught us that these big scary predators are the driving force that keeps ecosystems healthy. That means we have to learn to live with them if we want any other wildlife to flourish.

Sweden’s bid to get beyond the old shoot-shovel-and-shut-up psychology to one where herders and carnivores celebrate a happy event more or less together could thus be our best way forward.

  1. There must be another story behind this: how have the people adapted to protect their animals from the growing number of predators?
