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.

Carnivores and Scavengers are not well accepted in rural comunities although they play an important role in the ecosystem and their presence benefits humans through ecosystem services. This video shows the variety of animals that can feed on carrion. Enjoy it and share!

Classics: the Allee effect

ConservationBytes.com

220px-Vortex_in_draining_bottle_of_waterAs humanity plunders its only home and continues destroying the very life that sustains our ‘success’, certain concepts in ecology, evolution and conservation biology are being examined in greater detail in an attempt to apply them to restoring at least some elements of our ravaged biodiversity.

One of these concepts has been largely overlooked in the last 30 years, but is making a conceptual comeback as the processes of extinction become better quantified. The so-called Allee effect can be broadly defined as a “…positive relationship between any component of individual fitness and either numbers or density of conspecifics” (Stephens et al. 1999, Oikos 87:185-190) and is attributed to Warder Clyde Allee, an American ecologist from the early half of the 20th century, although he himself did not coin the term. Odum referred to it as “Allee’s principle”, and over time, the concept morphed into…

The California Department of Fish and Wildlife (CDFW) has photographic evidence of five gray wolf pups and two adults in Northern California.

Wolf Pups  JPG

After trail cameras recorded a lone canid in May and July, CDFW deployed additional cameras, one of which took multiple photos showing five pups, which appear to be a few months old and others showing individual adults. Because of the proximity to the original camera locations, it is likely the adult previously photographed in May and July is associated with the group of pups.

“This news is exciting for California,” said Charlton H. Bonham, CDFW Director. “We knew wolves would eventually return home to the state and it appears now is the time.”

CDFW has designated this group (comprised of two adults and five pups) the Shasta Pack.

The Risk of Captive Carnivores

I would like to share with you a very interesting article written by the The Endangered Wildlife Trust (EWT) about the risk of keeping carnivores in captivity and the bussiness behind. Many so-called NGO`S, Charities, etc which argue to work for carnivore conservation are part of one of the most unethical bussiness. Not only they keep wild animals in captivity as pets but also translocated what they call “problem animals” to new areas without monitoring the translocation, without a scientific protocol and viability study and sometimes (most of the times) without even a permit.. Please read and share the article, it would help you to identify who are this so called NGO´s and Charities:

The Endangered Wildlife Trust (EWT) is growing increasingly concerned about the proliferation of captive facilities holding a range of carnivores in South Africa for the sole purpose of tourism and financial gain. We urge the public to consider a few facts when visiting any of a number of these facilities that hold lions, Cheetah, Leopards, Wild Dogs, hyena and even some exotic (non-native to South Africa) species such as tigers and panthers.

* No captive carnivore facility is breeding carnivores for release into the wild, despite what they may claim. Captive carnivores do not contribute to the conservation of free roaming populations; they are not releasable and they do not form part of any registered conservation or management plan for any carnivore in Africa.

* In many carnivore facilities, petting and bottle feeding of cubs is offered, for a fee. These cubs are often taken away from their mothers to stimulate faster reproduction and provide aconstant supply of petting carnivores. Visitors pay to pet the animal and have their photograph taken with it, as well as with their slightly older tame carnivore siblings.

* These carnivores become human imprinted, they do not grow up in a natural social group, and this makes it impossible to release them into a natural habitat for the long-term. This, coupled with the disease risk posed by captive bred animals, as well as their potentially dubious genetic lineage renders them a risk for release to not only themselves, but to other free roaming carnivores.

* Frequently the situation of a ‘paying volunteer’ is exploited for further financial gain, with volunteers being told that the carnivore mothers are not able to care for their offspring and that once they are old enough, hand-raised carnivores will be returned to the wild.

* “There are approximately 6 000 captive lions in South Africa bred for a variety of economic purposes”, as opposed to approximately 2 300 free roaming in reserves and parks. [Draft Biodiversity Management Plan (BMP) for Lions, 2015]. In fact the BMP defines Captive Lions as being “lions [that] are bred exclusively to generate money. Managers actively manipulate all vital rates and demographics.”

The EWT’s concern relates to the public’s understanding of the role and the purpose of captive carnivores and these facilities in carnivore conservation and we urge the public to better understand the role of these facilities as well as the risk that these animals may pose to the public:

* Captive bred carnivores are always more dangerous than their wild counterparts. They lose their fear of humans and tend to associate humans with food providers. Their social structures are heavily interfered with and their natural cycles are often manipulated. A wild carnivore will usually steer away from humans but a captive bred carnivore may not feel the need for such caution.

*  A facility breeding carnivores will usually have to sell their offspring; it stands to reason that they cannot always have cubs and youngsters if they do not sell ‘excess’ animals.

* The captive bred lion hunting industry in South Africa has increased rapidly in recent years and South Africa is increasingly supplying captive bred lion bones for export to Asian markets.

* The Department of Environmental Affairs released figures in December 2013 that stated that “South Africa officially issued permits for the export of nearly (if not more than) 1 300 dead lions from South Africa to China, Lao PDR and Viet Nam from 2011 to 2012 inclusive.” BMP, 2015.

* “The so-called ‘canned hunting’ industry for lions has also increased in recent years and the total value generated from hunting captive lions amounted to about R98 million in 2006/2007.” Lion BMP, 2015.

* This raises the question: where do all these lions come from or go to? In South Africa, a thriving canned hunting industry can, in many cases, be linked to an equally thriving industry based on cub petting and commercial captive breeding centres.

Some may argue that there is educational value in allowing people to handle wild animals. Howeverthis kind of education provides the incorrect message that wild animals exist for human entertainment, that they can be petted like domestic animals. They also do not learn much about the natural behaviour, social structure or role of free roaming carnivores.
It is important to note that captive breeding is not a conservation recommendation for any carnivore species in South Africa. Carnivores in fact breed extremely well in the right conditions and for almostall our threatened carnivore species, the conservation priorities include reducing human-wildlife conflict, securing suitable habitat, reducing illegal offtake and maintaining balanced, functioning ecosystems. Without these in place, captive breeding leads to an over-supply of non-releasable animals which often end up as trophies. We also question that any funding generated from captive carnivore breeding goes to support the conservation of free roaming carnivores.

The EWT does not allege that any specific facility is breeding carnivores for the lion bone trade or forthe practice of ‘canned hunting’ but we do urge the public that visit these facilities to ask at the very least these critical questions:
· What is the plan for the long-term future of the animals in this facility?
· Where are the cubs’ mothers?
· Why are cubs not being raised by their mothers?
· What happens to the facility’s cubs when they grow up?
· If they are released into larger wildlife areas, where are these and can the facility provide documentation to prove a viable, ethical and successful release process?
· If the facility is breeding, do they have a management plan that determines responsible husbandry and management of all stock?
· Do any of the ‘stock’ have the opportunity to live out their natural lives, or are they hunted or bred with again?
· What happens to the facility’s surplus animals?
· Can the public inspect the record books of the facility and follow the life cycle of an individual animal?
· If these animals become part of another breeding programme, for what purpose?

The EWT calls for a more active participation from the public in questioning the role of all captive carnivore facilities and the management of the animals in their care. We also call on the tourism sector to recognise the role that they may be playing in supporting some facilities that cannot account for the conservation claims that they make.
