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.

Yellowstone National Park is one of the largest and oldest national parks in American history. Yellowstone was the first park to be protected by private investment on March 1, 1872, and the first to be put under the jurisdiction of the National Park Service in 1918, no doubt due to its unique and inspiring landscape and geothermal features. In fact, Yellowstone National Park is home to half of the world’s total hydrothermal features. These awesome attractions draw an incredible amount of visitors, an average of two to three million each year, to Yellowstone’s immense landscape. The park has a total size of 28,125 square miles, is found in three distinct states, and is considered to be one of the largest

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

Water contamination is vastly becoming an alarming issue across the world. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution (www.nrdc.org). Clean and plentiful water is the cornerstone of prosperous communities. Yet as we enter the 21st century, swelling demand and changing climate patterns are

From what I had learned, Yellowstone National Park was the first national park ever to be established in the world. It had over 3,500 square miles of beautiful scenery and wildlife. The park itself was mostly located in Wyoming, however, less than 5% was located in Montana and Idaho. Yellowstone has been a park since March 1st, 1872, and since then there have been hundreds of thousands of tourists that go there each year to see the amazing things it has to offer. Old Faithful, one of Yellowstone's main attractions, is a

1. Develop hypotheses predicting the effect of pyrite and coal on the acidity of water?

b. The emperor Kangxi led the conquest of the island of Taiwan , home to Chinese and Japanese pirates, in 1681. Struggles with a new rival to the north and northwest, manchurians , led to constant conflict and extensive territorial gains for China.

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

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 effect of the new wolf population was a miracle beyond hope, the ecosystem began to recover and diversify greatly. When the wolves were introduced it was found that they killed elk and restored their numbers to something the ecosystem could carry in conjunction with other species who feed on similar resources. In this way a surge of beaver population can be noted, as a result of beaver population increase the rivers became more stable and lodging was created for a half dozen species. It was also found that with the hunting of elk wolves left behind food for other animals whose populations also greatly benefited from this new predator. With the reintroduction of this alpha predator, the ecosystem made great strides toward recovering and diversifying, stream traveled slowly, meandered less and forest began to grow anew. Despite some arguments that Grey Wolves are a menace to the area or sensationalist report trying to discredit the wolf the results are clear. While man was responsible for the over hunting of the Grey Wolf in the 20th century, at its end the mistakes were rectified and the ecosystem shifted back into

Yellowstone is one of the largest, intact, temperate ecosystems in the world, and has all of the original species from when Europeans first started settling in the united states. Garrott talked mainly about wildlife issues in Yellowstone national park, including the commercial slaughter of bison and their re-introduction to the park, the introduction of non-native mountain goats and their possible impact, complications between the agriculture industry and native bighorn sheep, and the fight to decide the registration of wolverines as an endangered

Thirteen years ago, wolves were reintroduced to Yellowstone National Park. Of two potential locations considered (Snowflake Springs and Butte Rock) they were placed in the low-risk prey Butte Rock for the purpose of encouraging the wolves to spread out and create packs. Before and during the reintroduction project, Oregon State University researchers measured the rate of willow growth along 2.6 miles of the Gallatin River, which ran through Butte Rock and Snowflake Springs. During their study from 1998 to 2002, the researchers discovered that Snowflake Springs, where the elk were and no wolves lived, the willow growth dropped from 92% to nothing (“How Wolves Help Willows,” 4).
