Human-Wolf conflict in Germany

I have found a very interesting article written in the website of the European Wilderness Society on the Wolf in Germany. Access to original source here.

The story is not new to those who work with large carnivores in human dominated environments. Some part of the society asks to protect this icon of the wilderness while others are lobbying for legal killing.

The previous research done on this topic shows that legal killing will not help to diminish ilegal killing of the species nor reduce the livestock losses. Where there are large carnivores and free-ranging unprotected livestock, there will be always a conflict. We must assume it. The goals (everybody´s goal) should be to diminish such losses while keeping viable populations of these carnivore that are healthy and populated enough to have their role in the ecosystem.

In the link provided at the beginning of this article, you can find valuable information on the insignificant economic losses that wolves produce. The wolf’s damage counts thus for 0,08% of the total wildlife-damage in Germany.

There are currently 70 confirmed wolf packs in Germany. Aproximately the same amount than Galicia, in the north west of Spain with a size of 2/3 of Switzerland.

Livestock protection is the long term solution

Killing of wolves has counterproductive effects as it breaks the pack structure. The flow of experience and  learning process from the elders to the younger animals is one of the most important factors in order that wolves learn how to hunt wild animals like wild boar, red deer or roe deer. If the elders are killed, the young ones will seek easier prey like livestock. Killing wolves does increase livestock damage and human wild life conflict.

The most effective solution is to protect the livestock using electric fences, guarding dogs and other methods to dissuade wolves approaching the livestock.

Some essentials on coexisting with carnivores

Coexisting with carnivores can be a challenge, but their value makes it worthwhile, as Professor John Vucetich and Professor David Macdonald explain

The well-being of many human communities depends on healthy forests and grasslands. Those ecosystems can be degraded by over-browsing and over-grazing by large herbivores – moose, deer, elk, gazelles and so forth. That overconsumption is far less likely to occur when large herbivores are limited by healthy populations of large carnivore – wolves, lions, lynx, wolverine, bears, etc. Moreover, ecosystems with healthy populations of large carnivores tend to have greater levels of overall biodiversity. In a nutshell, and at risk of glossing over details, the conservation community has concluded that large carnivores have great ecological value.

Nevertheless, human communities often find it difficult to live near populations of large carnivores. Difficulties arise in three ways. First, carnivores kill domestic livestock, which provides for the well-being of some humans. Carnivores do not kill for malice; they do so because their well-being depends on it. Moreover, carnivores would naturally prey on wild animals. In many cases, however, the wild prey have been displaced by domestic livestock.

Second, carnivores kill wild prey that is also hunted by humans for subsistence or recreation. In this way, large carnivores are treated as competition to be eliminated.

Third, some species of large carnivores, on some occasions, threaten and take human lives. Important examples include human-eating lions in portions of Africa and human-eating tigers in portions of south Asia.

While these three elements of conflict are real, they are also frequently and grossly exaggerated. In the United States, for example, the impacts of wolves on livestock and hunting are very small and wolves do not pose a threat to human safety1. Yet, these concerns are an important fuel for wolf persecution.

Under threat

Genuine and perceived threats lead to humans killing carnivores at high rates through illegal poaching and legal culling and hunting. The result of all this killing is that two-thirds of the world’s carnivore species are threatened with extinction and most places do not have their native compliment of carnivores. The end point of treating this conflict – as humanity has thus far – is irreversible extinction and gross mistreatment of carnivores that manage to persist. An important element of this conflict concerns the received and oft-repeated motivation offered for why carnivores should be treated better: because they are ultimately of value to humans. The genuine wellbeing of humans is an important reason to conserve, but it is not the only one and alone it is inadequate.

European colonists and their descendants drove various large carnivores to extinction over a substantial portion of eastern North America. Britain drove its large carnivores – wolves, lynx and brown bears – to extinction centuries ago. It is difficult to mount a case that the wellbeing of those humans is worse as a result of those extinctions. When an object (think, carnivores) is valued only for its utility, its utility may go unrecognised, be outweighed by costs of maintaining it, or replaced by a substitute. This is not a denial of carnivores’ utility, but an acknowledgement of the risk in valuing something only for its utility. As such, nature’s utility is an (important, but) insufficient motivation for conservation.

Conserving carnivores

What if, carnivores are valuable, not only for advancing human wellbeing but also because they have a value in their own right? What if, we have an obligation to treat carnivores fairly and with at least some concern for their wellbeing? The response to those questions begins with the supposition that humans possess this kind of value and are entitled to this kind of treatment because we have interests (e.g., to avoid pain and to flourish). It follows that any entity with such interests would also possess this kind of value. Because all vertebrate organisms possess those interests, they also possess this kind of value and deserve this kind of treatment. The force and universality of this reasoning are indicated by the principle of ethical consistency, i.e., treat others as you would consent to be treated in the same position. Most human cultures are undergirded by some variant of this principle (e.g., golden rule). This intrinsic value of at least some non-human portions of nature is widely acknowledged – reflected by sociological evidence and many instances of laws and policies. Ethicists encapsulate these ideas by saying that carnivores (and many other forms of life) possess intrinsic value2.

Future success in carnivore conservation will depend, in part, on better understanding ideas that will foster effective and fair mitigation and adjudication of conflict, especially:

  • The extent to which conservation can be achieved through protected areas and land-sparing, opposed to land sharing3;
  • Mechanisms of socioeconomic behaviour that adversely impact carnivores. Some elements may be underappreciated (e.g., wealth inequality,4) and other elements may be favourable to conservation (e.g., tendency to increasingly embrace nature’s intrinsic value with increasing economic development,5);
  • How to subsidise coexistence by compensating those adversely affected by living with carnivores. The challenge is tailoring compensation in ways that are fair and effective, yet do not foster, e.g., perverse incentives, additionality, or leakage6;
  • How to best juxtapose the values of conservation and social justice in a manner that genuinely honours the intrinsic value of carnivores without being misanthropic7.

Conservation is no longer limited by ecological knowledge about carnivores’ ecological value or needs. Increasingly, the limiting factor is an effective application of knowledge arising from the synthesis of social sciences, social justice and conservation.

Blood does not buy goodwill

In the paper published Guillaume Chapron and Adrian treves in Proceedings B of the Royal Society (Blood does not buy goodwill: allowing culling increases poaching of a large carnivore), the authors looked at whether removing protection for large carnivores would decrease illegal hunting. This idea is supported by many governments. Does it work as expected? Find out by watching this video and by reading the paper available at http://rspb.royalsocietypublishing.org/content/283/1830/20152939.

Abstract of the paper:

Quantifying environmental crime and the effectiveness of policy interventions is difficult because perpetrators typically conceal evidence. To prevent illegal uses of natural resources, such as poaching endangered species, governments have advocated granting policy flexibility to local authorities by liberalizing culling or hunting of large carnivores. We present the first quantitative evaluation of the hypothesis that liberalizing culling will reduce poaching and improve population status of an endangered carnivore. We show that allowing wolf (Canis lupus) culling was substantially more likely to increase poaching than reduce it. Replicated, quasi-experimental changes in wolf policies in Wisconsin and Michigan, USA, revealed that a repeated policy signal to allow state culling triggered repeated slowdowns in wolf population growth, irrespective of the policy implementation measured as the number of wolves killed. The most likely explanation for these slowdowns was poaching and alternative explanations found no support. When the government kills a protected species, the perceived value of each individual of that species may decline; so liberalizing wolf culling may have sent a negative message about the value of wolves or acceptability of poaching. Our results suggest that granting management flexibility for endangered species to address illegal behaviour may instead promote such behaviour.

Does hunting impact carnivore recruitment?

Recruitment in a social carnivore before and after harvest” is the title of a recent paper published on the Journal Animal Conservation of the Zoological Society of London that shows collateral impacts of harvesting wolves:

We attributed just 18–38% of pup mortality directly to harvest and suggest that there are indirect effects of harvest on recruitment that may be associated with changes in group size and structure. Models that do not include both direct and indirect effects of harvest on recruitment may underestimate the potential impact of harvest on population growth in social species.”

REINTRODUCING WOLVES IS ONLY EFFECTIVE AT LARGE SCALES

It is a rule in ecology that big animals outcompete little animals. Sometimes the big animals kill the little animals, sometimes the big animals eat the little animals, and sometimes the big animals drive the little animals out of one territory and into another, safer one. That basic pattern – “interspecific competitive killing” – has pushed scientists to try to understand how large carnivores shape entire ecosystems. Continue reading

Judge rules to keep gray wolves on endangered species list

Great news from USA! Great job done by the Scientists. You can download the letter sent to the judge HERE.

As scientists with expertise in carnivore taxonomy and conservation biology, we are writing to express serious concerns with a recent draft rule leaked to the press that proposes to remove Endangered Species Act protections for gray wolves across the Lower 48 States, excluding the range of the Mexican gray wolf. Collectively, we represent many of the scientists responsible for the research referenced in the draft rule. Based on a careful review of the rule, we do not believe that the rule reflects the conclusions of our work or the best available science concerning the recovery of wolves, or is in accordance with the fundamental purpose of the Endangered Species Act to conserve endangered species and the ecosystems upon which they depend.

Why Is Canada’s Wolf Population Splitting Into Two Groups?

Why Is Canada's Wolf Population Splitting Into Two Groups?

Chester Starr of the Heiltsuk First Nation knows that the wolves of British Columbia come in two varieties: timber wolves on the mainland and coastal wolves on the islands. Genetic research has finally confirmed what Starr’s tribe has always known.

It was Starr’s “traditional ecological knowledge” that initially inspired Polish Academy of Sciences researcher Astrid V. Stronen and University of Calgary scientist Erin Navid to take a closer look at British Columbia’s wolves. They wanted to see whether the Heiltsuk Nation’s folk knowledge was reflected in the wolves’ genes. Continue reading
