Reintroducing Wolves to Yellowstone National Park

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.

During the 1940’s, wolves were exterminated from Colorado and few have come back since. As a result the ecosystem that we have in Colorado is somewhat skewed due to the absence of them. Many people think that wolves are a nuisance and would get in the way of the agricultural style that colorado has. However, wolves are considered a keystone species which means their “presence would reinvigorate the natural order” (clifford). For this reason wolves should be reintroduced into montezuma county. The reintroduction would greatly benefit and restore the balance of our ecosystem.

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).

Since the reintroduction of wolves into Yellowstone they have created an astounding and advantageous trophic cascade. A trophic cascade is an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain. These often result in dramatic changes in ecosystem structure and nutrient cycling. In a three-level food chain, an increase (or decrease) in carnivores causes a decrease (or increase) in herbivores and an increase (or decrease) in primary producers such as plants and phytoplankton according to briticanna (how to make better). The entire ecosystem was able to become whole again because the wolves, a key species, were reintroduced. Now this may seem weird, a predator comes into the area a begins to kill animals, how can this be beneficial in any way? Well the fact of the matter is that it is extremely beneficial. The reason being the problem in Yellowstone was the overpopulation of the elk. These elk had no predators, they were free to roam and reproduce, and they did this very well. Now elk are also a

Gauss’ Law states that no two organisms can occupy the same ecological niche without excluding the other, but what happens when man gets involved with nature and tries to introduce a species where it doesn’t belong which in turn provides a second organism to fill the same niche as the first? The results of human intervention have often been disastrous for the organism that we’re supposedly helping. Humans often times do not understand the complexity of the implications that are caused directly through our intervention. In 1974, the gray wolf was listed on the Endangered Species List, and in an effort to reestablish their populations, wolves were re-introduced into Yellowstone

“Restoring an ecologically complete ecosystem in Yellowstone requires the return of willows--and with them, beavers. There's a clear threshold for ecosystem recovery. Willow stands must be more than 6 feet tall, the scientists found. That height is important, says Marshall. Then willows are beyond the reach of browsing elk, and can serve as seed sources for new young willows. Once willows have returned, beavers will gnaw down a certain number of them to build dams. The dams will further slow stream flow, allowing yet more willows to grow. The results offer new insights on the role of wolf-driven trophic cascades in the Yellowstone ecosystem, says Hobbs. Trophic cascades like that in Yellowstone occur when predators--or the lack thereof--in an ecosystem change the abundance or alter traits of their prey, in turn affecting the next lower trophic level.” ("National Science Foundation", 2013)

Ed Yong makes very valid points on how the wolves of Yellowstone have impacted the overly populated elk herds. He has this to say about the herds; “Today the population stands at just over 6,000 down from 19,000 in the elk’s wolf-free heyday,” (ll57). This might seem like a terrible drop in the elk’s numbers, but it is actually a good thing. Yong tells us, “The large deer had run amok in the wolf-free decades, causing serious damage to the park’s trees,” (ll5-6). So in reality, while there are far less elk now, the trees can start to build back up again.

Wolf recovery would be a big step in maintaining wildlife. For instance, in Yellowstone a

I am taking a class called global environmental issues and heard about how reintroduction of wolves has had very positive impact in Yellowstone, but we did not go much deeper than just stating so.

The two relationships mentioned previously end up interconnecting with one another. Feeding the bears from the human-and-nature relationship not only impacts humans, but it also impacts Yellowstone. Same for the wildfire example from the humans-and-humans relationship.

In May, 2016, 20 calves were killed and not eaten in four days in the area of the Absaroka Mountains, outside of Pinedale Wyoming. (Urbigkit ,2016) However, it doesn’t stop there, every day livestock and wildlife are killed and rarely eaten by wolves in almost every western state. This is a problem that needs to be addressed before ranchers lose their herds, and before the wild herds are depleted beyond restoration. If the wolf situation was bad a couple years ago, well now it’s worse, even some of the “protectors of wildlife” are starting to come to their senses.

In this article, authors William Ripple and Robert Beschta focus on the issue of predation and the way it affects biodiversity and otherwise alters ecosystems. While many other studies have stressed the lethal effects of predation by carnivores, the authors of this study have chosen to focus on how nonlethal outcomes of predation affect the structure and function of ecosystems. The authors give two main objectives to their study: first to provide a short synthesis of the potential ecosystem responses to predation risk in a three-level trophic cascade involving large carnivores, hoofed animals, and vegetation; and secondly to present research that centers on wolves, elk, and woody browse species in the northern area of Yellowstone National

In 1924 because of a “government policy the federal government deliberately killed all the wolf packs” in Yellowstone National Park in Wyoming. This policy was passed because of the lack of knowledge and fear. These animals have been a scapegoat throughout human history. But what happens when we take a large predatory animal out of the ecosystem; when we keep the big bad wolf from doing its part in the environment.

It's a cold December night on the ranch, and you are slowly drifting off to sleep, when a sudden howl brings a shiver up your spine. You look out your window and see a Gray Wolf, the snow caresing its soft, eligant face, beautiful. When morning comes you go out to your livestock pen, one dead, that could cost you up to $20,000, that beautiful creature no longer seems so beautiful. In 1995, on accord of the Endangered Species Act, the Gray Wolf was introduced to Yellowstone National Park, Since then the ecosystem has flourished and more animals have come, rivers are not caving, trees are blooming and more plants are growing and tourism has exploded. So was wolf reintroduction really a good thing.

It is early in the morning; the majestic Elk bugles in the distance. The sun is kissing the tops of the peaks with the most beautiful gold, and painting the clouds rose red. The men and women who enjoy the outdoors whether it is hunting or just hiking help make these types of moments possible. Hunting and the ecosystem is tied closely to conservation of land and animals. The articles of “Hunting and the ecosystem” written by the South Dakota Game Fish and Parks Department (SDGFP), and “Facts and statistics on wildlife conservation” written by Roger Holmes, director of the Fish and Wildlife, touch on how hunting is important in the environment to keep a good balance in the ecosystem. They also point out how hunters do more than any other
