Reintroduction of Wolves at Yellowstone Park Introduction While highly controversial, the reintroduction of wolves in Yellowstone Park has provided many beneficial ecological changes to the entire parks ecosystem. After a nearly 70 year absence, in January of 1995, 14 wolves from separate packs were captured in the Canadian Rockies and transported to Yellowstone National Park in the states of Wyoming, Montana and Idaho (Sanders par. 2). The Canis Lupus or more commonly known as the gray wolf is the largest wild member in the Canine family. While once covering vast areas of the North American and European continent, the grey wolf was hunted to near extinction in the 1900’s due to mostly folk lore and fear. There were at least 136 confirmed kills between 1914 and 1926, and by the 1970’s biologist could find no evidence of a wolf population in Yellowstone Park. (National Park Service par. 1). Wolves were highly populated when the park opened in 1872 but due to predator control measures, lack of legal protection for the species, and the classification as a nuisance animal all played factors that led to their absence in the park. It was for this reason that the gray wolf was placed on the Endangered Species List in 1974 and it has taken until 2008 and more than 27 million dollars to bring the species back into a suitable population and remove them from the endangered list (Associated Press par. 12). The move to reintroduce the wolf was very controversial with conservational and environmental groups pushing and supporting the measure but many ranchers and farmers in the area being very wary of it. But there was no denying that the ecosystem of the park had changed since the wolves’ absence, with a large

    As stated earlier, the 2004-2005 survey conducted by the Wisconsin DNR showed that 52 percent of Wisconsin citizens do not support compensation for hounds, yet the money from these citizens is still used to provide compensation to the hunter. The same survey discovered that 81 percent of landowners that live near wolf packs would participate in a program in which they are given a monetary incentive to protect wolves, which would offset the risks they face and compensate them for any potential animal losses. This proves that wolves are not the problem; the problem is how the compensation is funded and handled. During the 2012 Wisconsin wolf hunting season, the compensation for dog depredations was provided through wolf application fees instead of taxpayer dollars. Managing the wolf population not only involves hunting, but also dealing with the consequences and side effects of having a wolf population in the state of Wisconsin. The money that was earned from wolf hunting application fees during 2012 was used directly to compensate hunters for wolves that caused them problems, which was a much more beneficial management…

    The finial reason that grey wolves should not be reintroduced to the Yellowstone area is that the elk populations will deplete severely. At the end of the year of 2012 there were at least 97 wolves in the park, and those wolves killed 211 elk. Reports have shown that 60% of the population has died. Going from 15,000 to 6,000. If the wolves continue to reproduce and multiply as they are doing now than in the near future there may not be any more elk in the Yellowstone National Park.…

    Wolf Hunting Case Study

    Case study 1 examines the current debate on wolf hunting taking place in Michigan. Wolves impact the ecosystems in which they live by keeping the role of predator and prey in balance. There must be enough wolves (supply) to fulfil this role (demand). The legalization of wolf hunting may not directly relate to economics but can be used to compare balancing an ecosystem versus balancing the market. The economic problem presented in the video is how to go about maintaining this balance. When natural resources are scarce who should make the decisions on how to use these resources individuals or the government.…

    Wolves and humans have been coexisting for hundreds of years. Before Europeans conquered our vast country, wolves held a very esteemed place in Native American culture, as they were vital to forest ecosystems, and were often believed to be spiritual beings in many tribes (kidsplanet 1). As much as they were honored in tribal cultures, others feared them. Children’s fables often described them as “the big bad wolf” in stories such as Little Red Riding hood and The Three Little Pigs (kidsplanet 1). Settlers saw wolves in this way because they were a sort of competition, dwindling stock and wild game numbers (kidsplanet 1). Even into the 20th century, the belief that wolves were still a threat to human safety continued despite documentation to the contrary, and by the 1970s, the lower forty eight states had wolf populations less than three percent of their historical range, about 500 to 1,000 wolves (kidsplanet 1). In a book written by Bruce Hampton called The Great American Wolf, he states,…

    Gray Wolf Habitat

    Wolf reintroduction is only considered where large tracts of suitable wilderness still exist and where certain prey species are abundant enough to support a predetermined wolf population. The five last known wild Mexican grey wolves were captured in 1980 in accordance with an agreement between the United States and Mexico intended to save the critically endangered subspecies. Since then, a comprehensive captive breeding program has brought Mexican wolves back from the brink. Currently, there are 300 captive Mexican wolves taking part in the program. The ultimate goal for these wolves, however, is to reintroduce them to areas of their former range. In March 1998, this reintroduction campaign began with the releasing of three packs into the Apache-Sit greaves National Forest in Arizona. Today, there may be up to 50 wild Mexican wolves in Arizona and New Mexico. The final goal for Mexican wolf recovery is a wild, self-sustaining population of at least 100…

    Nature has been restricted in a "closed" system since humans have settled in America and created a world for themselves. Many animals have gone extinct or lost their homes as a result of humans paving roads for travel, destroying forests to build houses, and much more. Animals have started to go extinct because they have been restricted in what they can eat or where they can live due to human behavior. Humans don 't understand the importance of having nature connected rather than having nature broken into several areas. In the passage, " Rewilding North America" by Caroline Fraser, Fraser discusses many solutions on how to save the wildlife and help humans live with an "open" nature system. Fraser shows a research conducted on a wolf, Pluie,…

    “When the gray wolf was extirpated from Yellowstone National Park in the 1920s, more was lost than just the noble and fascinating predator. The park’s entire ecosystem changed. Now, nearly a dozen years since the wolves returned, the recovery of that system to its natural balance is well underway”, say ecologists William Ripple and Robert Beschta of Oregon State University.…

    The gray wolf is endangered because of wolf slaughter.Wolf slaughter went nationwide in the lower 48 states. Montana let 6,000 people kill wolves and the all got to kill 5 each. Hunters kill wolves for fun so that they can have another pelt in their collection. The most common death of gray wolves is hunting and trapping. Some people kill wolves because wolves go after the week and not as strong elk and deer and that's what hunters go after…

    As in the case of the Arizona agave, it was recovered and removed from the endangered species list due to the hybridization of two common and abundant species of agave as they essentially overlapped. By the same token, the Mexican wolf was subsequently thrown into endangerment due to improper conservation evaluations and lack of ecological research. This goes to show that ecology has come a long way since the nineteenth century, and has ultimately worked its way toward better scientific evaluations and stricter conservation…

    The Nature of Wolves

    There is very little knowledge in the public about the nature of wolves. From my own personal knowledge and from doing research I would like to inform the public about the wolf and help them to understand that the idea of the little red riding hood wolf, which attacks humans, doesn 't really exist. Information is the key to successful wolf ad-vocacy. There are now a few small wolf populations scattered throughout the United States. As the federal government edges closer to desisting the wolf, as an endangered species, those populations will face multiplying dangers. We must make sure that the next generation carries on with wolf recovery. The best way to do that is through educa-tion.…

    Wolves are a natural part of the Swedish ecology and should have a right to remain in it. Wolves brings a balance to the nature, Studies have shown that when a predator return to an ecosystem it can trigger a trophic cascade effect; a chain of events that occur and gives impact to the whole ecosystem. This effect occurred in Yellowstone national park in the United States of America, in which the positive effects on park and the mayor variety of wildlife there was astonishing.3Although it is impossible to know how great of an in pact it would have on the Swedish fauna; to let the wolf population grow freely, although one could logically assume that it will reduce over population of moose and deer, in which would help the forests and fields to grow more frequently, which could for example also be economically beneficial for forest owners. It could also be argued that wolves will help lowering the fatal wildlife traffic accidents with the moose. The wolf also reduces the fox population, which actually helps smaller game like Hares and Grouse.4…
