Mexican Wolf Reintroduction

The Mexican gray wolf is a large prey that, in the past, preyed on livestock which contributed to their near extinction by humans. However, the decline in the Mexican wolf lead to an overabundance in plant life which had a direct effect on other wildlife. There are many challenges involved with re-introducing wolves to other stakeholders such as to academics, mangers, ranchers, or landowners. It is not as simple as taking the Mexican wolf from where they are now and placing them in different areas in Arizona, New Mexico, the US, and across the border in Sonora, Mexico. This is a very large area of land that policies would have to cover. The best ways to illustrate that this concept is not as easy as it may seem are best described by nature culture dichotomy, social-ecological systems involving ecosystems with people, and the Anthropocene comprised with the idea of humans as agents of change.

The red wolf is listed as endangered under the U. S. Endangered Species Act (ESA) (United States Public Law No. 93-205; United States Code Title 16 Section 1531 et seq.). Wild red wolves inhabiting the north eastern North Carolina (NENC), USA recovery area and a single island propagation site (St. Vincent NWR, Florida) are designated as experimental non-essential populations under Section 10(j) of the ESA. The IUCN Red List of Threatened Species lists the red wolf’s status as critically endangered.

According to the Endangered Wolf Center website, the maned wolf is the only species in its genus. It is reddish-orange color with brownish-black stockings with small eyes. The maned wolf’s habitat is found in large prairies, lush forests and wide grasslands of South America. The maned wolf was nearly hunted to extinction by farmers who mistakenly blamed it for killing their life stock. Zoologist were able to demonstrate that due to their small jaws and teeth the maned wolf could not have hunted large livestock (Guillermo Rosario Jaime). Unfortunately, the population was serious reduced and the situation escalated by the loss of habitat due to increase of human population. The maned wolf is an omnivore and diet includes: fruit, roots, and sugarcane. It was becoming very difficult to meet their dietary needs to have successful litters. Fortunately, in 1996, the development of the Species Survival Plan was developed to save the species. The first litter in the Wolf Center was born in 1998. There is still hope for

With the reintroduction of the Grey Wolf into the Greater Yellowstone Ecosystem there have been many people who are opposed. Mainly the ranchers in Montana

The biggest impact the reintroduction of wolves would make is that they control the population of large mammals such as elk. Without wolves in an ecosystem coyotes step into the role of the biggest predator. However coyotes are almost 2.5 times smaller than an average wolf so they are not big enough to kill much of the elk. The elk population then increases rapidly and hurts the ecosystem. Wolves also help reduce the spreading of disease by hunting on the elk that have been injured or have diseases. It gives the wolves a better chance of taking down the large animal and prevents

Over the past several years, the gray wolf, native to the Wisconsin area, has been listed federally as an endangered species due to the graphic and horrific treatment they had received during the industrialization periods of America, when they were frowned upon and hated because they are predatory creatures and did, on occasion, attack livestock and pets. Because the government was encouraging the hunting, including bounties for the animals, the wolves were hunted to near extinction. However, now Wisconsin faces a new problem. With the reintroduction of the wolves to the state, and their continued endangered status federally, the population has increased well beyond expectations, reaching what could be considered a problematic state. A

On May 3, 1995 female wolf number nine gave birth to eight puppies, the first wolves to be born in the park in nearly 70 years. The mother and pups were recaptured and taken back to the acclimation pen, until the pups were weaned (Sanders par. 15). The reason for this recapture was because at this time, this wolf and her eight pups counted for almost 50% of the park’s wolf population. Since this time there have been no other human interventions preferring to let nature take its course on the population.

Not many people understand the seriousness of endangered species. Some sources go as far as trying to prove that the act does more harm than good. They do not realize how drastically their lives can be changed if one part of the food chain is taken away. In the essay “Why the Beaver Should Thank the Wolf” by Mary Hannibal, the essayist explains that a group of environmental nonprofits would challenge the federal government’s removal of Endangered Species Act protections for wolves in Wyoming. Hannibal does not explain the Endangered Species Act, but according to the The National Oceanic and Atmospheric Administration it “provides for the conservation of species that are endangered or threatened throughout all or a significant portion of

When the wolves were first reintroduced, having 30 equally distributed breeding pairs was enough to constitute a success. A breeding pair is defined as an adult male and female wolf raising two or more pups in a year, where the pups are born between April and May and then raised till December 31. With the reintroduction of the gray wolf, a recovery population goal had to be established. That was the goal of the United States Fish and Wildlife Service (USFWS) for the recovery of the wolf population for the northern Rocky Mountains. Wolf numbers needed to be maintained at this level for at least three consecutive years. According to the USFWS 2002 was the third year where there had been at least 30 breeding pairs throughout Wyoming, Montana, and Idaho. After 2002, these wolves are still multiplying and the population continues to soar, even at this very moment.

In “Scared to Death” by Ed Yong and Sharon Levy’s “Wolf Family Values,” we read about the need to protect the population of wolves in North America. These two articles have very different ways to go about this. Ed Yong talks about the wolf effects on elk as well as the rest of the environment. Levy’s approach is about wolf social structure and how it is impacted by hunting. Both of these make some valid points on why more conservation efforts should be made; however, I believe Ed Yong made the stronger case.

The thesis of this article is that wolves, once endangered, have come back and started to flourish causing mixed feelings for locals and biologists. Wolves were once hunted because one, to protect livestock, and two, they were seen as pests and/or vermin. The government then put wolves under the endangered list to try to save them. Since then, wolf populations have multiplied.

The gray wolf is one of the world’s most well known and well researched animals with more documentation on them than any other wildlife species. It is a canid whose main habitats are in the wilderness of remote areas in North America, Eurasia and North Africa. It is the largest member of the wolf family, usually weighing between 70 and 120 lbs, and closely resembles in general appearance and proportions to a modern day breed of dog known as the German Sheppard, although they typically have a larger head, narrower chest, longer legs, straighter tails and bigger paws. The narrow chest of the gray wolf allows for swift and efficient movement through the common elements of their environment such as snow, brush and other conditions. Their larger heads indicate their higher level of intelligence and their large paws, webbed with fur aid in movement across mud and snow. The colour of a gray wolf’s fur lives up to its name and is predominantly a mottled gray although the gray wolf can also have fur that is nearly pure white, mixes of red, brown, or black. Being very social animals, gray wolves do mostly everything in packs of 2 – 15 animals; living, traveling and hunting. They can hunt and feed off smaller game, yet with their large pack size, they can work collectively to bring down large game such as deer, moose or bison. There are 37 recognized subspecies of the gray wolf in total ranging across six continents with familiar names that one

The United States Fish and Wildlife Service are considering removing the gray wolf from the endangered species list once Idaho, Montana, and Wyoming have enough wolves to be deemed sufficient to continue to expand the wolf population, requiring only that each of these three states have a management plan in effect to prevent the gray wolf from becoming endangered again. With the current attitude of the governments in these states, the wolf should not lose their federal support under the Endangered Species Act as it would merely serve to cause the wolves to become endangered once again, or at best, held to the absolute minimum population that the states can pass off as “viable, self-sustaining populations”

These were all key factors to their near extinction. In 1974 the wolves were placed under the Endangered Species Act (ESA), but were not protected for long. Many environmentalist agreed with this act because environmentalist knew how crucial this keystone specie was to the ecosystem. Without the grey wolves existence, the whole rest of the ecosystem would not function properly. Unfortunately, around the 1960s, the gray wolf population was basically extinct, which resulted in a huge controversy. Luckily, “In 1995, the first 14 wolves were introduced to the Yellowstone National Park to increase the wolf population”(Transplanted) that had been decreasing gradually. Over the years more Canadian wolves were introduced to the Yellowstone National park to increase the wolf population. This procedure was successful because the wolf population throughout the Yellowstone region was on the rise. The long term goal for the environmentalists and Yellowstone park rangers would be to have around 1,000 wolves roaming the region.

Red wolves have become endangered because of many reasons. One of these reasons are predator control programs. Some people believed that the red wolves were killing cattle and causing cattle loss in a large area, this led to people killing them for money because the misunderstood the red wolves. Their population was also affected by the clearing of land and other projects such as, mining, and the construction of roads. As a result, the area where red wolves are found has been drastically decreased.
