Essay on Conservation Biology in Yellowstone National Park

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).

“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)

Yellowstone National Park is located mostly in Wyoming but spreads into Idaho and Montana. Yellowstone national park has a Taiga biome. Taiga is the largest terrestrial biome in the world. It is primarily coniferous forest or boreal forest. The North American Taiga is at high elevations, in the mountainous western region. Within this park, there are various species of consumers, producers, prey, and predators. One very important species is the gray wolves. The gray wolves are one of the keystone species in Yellowstone National Park. A keystone species is a species that has a large effect on a community relative to the abundance of the species. This means that as the gray wolf population increases or decreases in this area, it will have some drastic effects on the entire community.

When herbivorous species such as white-tailed deer and elks are the main predators in a habitat, they create an imbalance in the habitat, and force other species in the habitat to go extinct. Natural predation also has a stronger impact in stabilizing or reducing the population of white-tailed deer than human hunting alone. One of the main reasons for the overpopulation of the deer was the extinction of their predators. Every animal in the food web is highly important in keeping the balance in the ecosystem. Yellowstone National Park was a great example of how every species support the

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

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

Yellowstone is the worlds first national park. It was origanally home to Native Americans who lived in the Yellowstone area for at least 11,000 years.The U.S. Army was first commissioned to oversee the park just after its establishment in late 1960. In 1917, administration of the park was transferred to the National Park Service. Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), mostly comprising lakes, rivers canyons and mountain ranges. The national park is located primarily in the state of Wyoming, although it also extends into Montana and Idaho. It was established by the U.S. Congressand signed into law by President Ulysses S. Grant on March 1, 1872.

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.

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”

One of the reasons I believe that Macbeth is a tragic hero is because he is of noble stature. This is true because he is a military general and the Thane of Glamis. If you are a military general you are a high rank and usually highly respected and have a large amount of responsibility. He is also a thane, which is someone who owns a large amount of land that is usually granted by the king. Thanes are also usually leaders of clans who are in control over a large amount of people.

It is believed that Native Americans inhabited the lands of what is now Yellowstone National Park for more than 11,000 years, until approximately 200 years ago, when European settlers began to drive many of them from their homelands. In 1872 Yellowstone was declared the world’s first national park as a way to preserve and protect the land for the “benefit and enjoyment of future generations.” (National Park Service) Yellowstone National Park covers a vast area in the Northwestern United States. Its landscape is very complex and ever changing thanks to the many geological forces that are found there. In fact, the unique geological features such as the geysers, hot springs, steam vents, among many others, are what lead to

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.

More than 900 species known on planet Earth have gone extinct (Endangered). Some, however, have been saved from extinction. One big contributor to this cause is the National Park Service, an organization founded in 1916 to protect the remaining wild places in our world. Now the National Park Service preserves over 6000 areas throughout the world, with over 275 million visitors each year (United, “What”; National, “National”). The National Park Service plays an essential role in preserving wildlife on Earth by teaching and acting to preserve species.

So far it has become evident that humans do not have a positive impact on the overall ecosystem of Yellowstone we have seen bear’s feeding patterns skewed, as well as elk populations devastated. There is yet another animal within yellowstone that has been impacted in a negative way by humans. John P. Beckmann is a conservation scientist who conducted research with several other scientists on the harvesting of energy and natural resources near or in yellowstone. When conducting his research he noticed that the harvesting of energy resources near yellowstone was affecting the pronghorn population. A subclaim that I can derive from my research on this topic is that the harvesting of energy and natural resources makes it tough to keep humans out of the way of
