The lush grasslands of North American grasslands spread throughout the United States Great Plains. The grasslands supply a home to many plants, species, and endangered species, such as the Northern Swift Fox, Vulpes Velox. The grasslands provide a beautiful habitat for the many species of wildlife to thrive and live because of the tall, mixed grass, Rocky Mountains, fertile soil, rainfall, and moderate temperatures. The conservation of the species of these grasslands have become extremely important, because if one endangered species such as the small, speedy Northern Swift Fox went extinct, horrible effects will occur. The grasslands provide a wonderful environment for the many plant and animal species, like the Northern Swift Fox, to enjoy.
The lush topography, moderate temperatures, wet rainfall, and fertile soil make the grasslands a great place for species to live in. The temperatures rise as high as one hundred degrees Fahrenheit, thirty-eight degrees Celsius, or as low as ten degrees Fahrenheit, negative twelve degrees Celsius. In the summer, the average temperature calculates to eighty-three degrees Fahrenheit, twenty-eight degrees Celsius. In the winter, the average temperature calculates to thirty-two degrees Fahrenheit, zero degrees Celsius. The grasslands create a perfect place for heat-loving and cold-craving species. The topography includes lots of tall grasses, mixed grasses, short grasses of the prairie, and the Rocky Mountains in the west. The well-drained and different soil types accord to different grass types. The tall grass rooted to rich soil benefits crops. Mixed grass soil, though dryer, still has some moisture. The dry short grass prairie soil profits animals living for a period of time without water. Th...

...the country. Humans need to take care of the northern swift fox species, or humans will have to wave goodbye to a cute, little fox. The life punishments of losing the northern swift foxes look endless.
The grasslands have become an important ecosystem to animals, plants, and humans. The swift fox has also showed significant to humans and animals of that ecosystem. Humans need to shine a light on the environment, and the world will at last see peace. “Most of the natural temperate grasslands of the world have been lost, but perhaps they have not been lost forever,” 3 says Michael Allaby, author of Biomes of the World - Temperate Grasslands. Hope for the temperate grasslands of North America and the Northern Swift Fox, Vulpes Velox, still persists. The North American temperate grasslands and the northern swift fox have become important to the present and the future.
In this research paper, I will address the changes that occurred within the ecosystem of Yellowstone National Park since the reintroduction of the grey wolves. The paper will consist of four sections; the first section will include the history behind the extirpation and subsequent reintroduction of the gray wolf in Northern America. The second section will explore the political controversy that surrounds the reintroduction of the gray wolf in Yellowstone. The third section will contain discuss the gray wolf and its impact on the ecosystem of Yellowstone. I will conclude my essay by explaining how the gray wolves act as climate change buffers in Yellowstone amidst global warming.

The meadow is one of the largest mountain meadows in Sequoia and Kings Canyon National Parks. People do not visit this meadow because there are no roads or official trails leading to this area. The meadow is suffering from overgrazing of cattle that took place for a century beginning in 1885 and ending around 1980. Livestock grazing causes many issues. For example, it affects the growth of trees, leads to the transmitting of diseases from the livestock to the wild animals, causes degradation of native plant communities, and a change in habitats for native wildlife species. The NPS would like to restore the Cahoon Meadow without disrupting the Wilderness character. Some people ask, why preserve this meadow if humans rarely see it? The answer is, meadows are ecologically significant because they support much of the wildlife and plant species that are accustomed there. Plant communities are widely diverse within meadows, and they provide essential habitats for a wide range of wildlife, including mammals, birds, amphibians, and invertebrates. As this meadow was being grazed, the wildlife, plant life, and natural beauty has been destroyed. As time has gone by, the only solution the National Park Service has attempted was to not physically restore the meadow but to just monitor
In conclusion, the reintroduction of gray wolves to Yellowstone National Park is an excellent example for future conservation efforts in the United States. The successful case shows that there is a need to restore gray wolf populations, in order to ensure optimal ecosystem functions. By observing the effects of the absence of a top predator from Yellowstone Park and the changes that have occurred after reintroduction, more people may be able to conclude that wolf populations are necessary for ecosystem balance and conservation. With this conclusion may come an increase in the future populations of gray wolves along with improved policy and awareness.

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.
The climate of the tundra is characterized by harsh winters. The average temperature in the tundra area is about –27 degrees. But what is even worse are the long night. At nights the lowest temperture recorded was –67.36 degrees. There are even times in the year when the sun doesn’t come up for days. In the tundra we have little snow and even less rainfall. The rainfall is about a quarter inch in a yearly rainfall. Even though the tundra’s winters are long a harsh there summers are the shortest season of all. Do to the terrible weather and climate in the tundra their animals and plant life is very limited.
Landscape fragmentation contributes to loss of migratory corridors, loss of connectivity and natural communities, which all lead to a loss of biodiversity for a region. Conservation of biodiversity must include all levels of diversity: genetic, species, community, and landscape (CNHP 1995). Each complex level is dependent upon and linked to the other levels. In addition, humans are linked to all levels of this hierarchy. A healthy natural and human environment go hand in hand (CNHP 1995). An important step in conservation planning, in order to guarantee both a healthy natural environment as well as a healthy human environment, is recognizing the most endangered elements.
The type of biome where dust bowls are known to occur is in the temperate grasslands. The typical climate in a temperate grassland biome includes very cold winters that drop below -40 degrees Fahrenheit and very warm summers that exceed over 100 degrees Fahrenheit. The precipitation level ranges from 10 to 35 inches per year. Most of the precipitation in this biome occurs during late spring and early summer.
The other day I was sitting with a friend of mine in a class, all of a sudden she turns to me saying, "You got to see this." Expecting to be handed a phone to read some text or watch a video to my surprise she hands me a copy of National Geographic turned to an article about the domestication of foxes. "Borrow it from me, I know you're into animal stuff, you got to read it." Only my friends would do this, but this article is a really great starting point to discussing pets. I think it is important to explain how I happened upon the article, because I doubt I would have gotten passed an article about wild foxes, or wild animals for that matter. The fact that they were able to breed foxes specifically to be pets for humans was the reason of interest, as her later comment that, "I totally want one, they are so adorable" shows . Pets are our strongest connection to the natural world; they are the part of nature we interact with on a day-to-day basis. Pet stores, like Petco which I visited, do a lot to mediate and influence manner in which relationships between people and their pets' form. Pets have a distinct role in people's lives as children, best friends, and members of the family which not only impact how the pet is treat it also impacts how other animals are seen and ranked in their importance towards humans.
In the last decade, from the Rockies to New England and the Deep South, rural and suburban areas have been beset by white-tailed deer gnawing shrubbery and crops, spreading disease and causing hundreds of thousands of auto wrecks. But the deer problem has proved even more profound, biologists say. Fast-multiplying herds are altering the ecology of forests, stripping them of native vegetation and eliminating niches for other wildlife. ' 'I don 't want to paint deer as Eastern devils, ' ' said Dr. McShea, a wildlife biologist associated with the National Zoo in Washington, ' 'but this is indicative of what happens when an ecosystem is out of whack. ' ' The damage is worse than anyone expected, he and other scientists say. Higher deer densities have affected growth, survival, and reproduction of many plant species which have aesthetic, economic or ecological value. In some cases, many species of trees have also been shown to have reduced growth as a result of high deer density (Environmental Benefits of Hunting, 1). Deer prefer certain plant species over others and frequently feed on economically valuable tree species. For example, they prefer oak and sugar maple seedlings, as well as acorns, over less palatable species like American Beech and striped maple. Thus, less marketable species are more likely to survive to maturity,

Estimates are that at the turn of the twentieth century over two million wild horses roamed free in the western United States. However, having no protection from their primary predator, man, by the 1970’s there numbers had dwindled to less than thirty thousand. In 1971, after a massive public uproar, Congress by a unanimous vote enacted the “Wild Free-Roaming Horse and Burro Act” (Act) that characterizes wild horses and burros as national treasures and provides for their protection.
The San Joaquin Kit fox has been listed has been listed as endangered since 1967 under the federal endangered list. San Joaquin Kit foxes are important in their ecosystem; they serve as a population control for smaller rodents the population has continued to decrease due to loss of habitat and degradation of the land caused by development. The efforts that have been made to protect this species are necessary for the species to avoid extinction. However, the efforts made to protect the species have yet to have positive results. Stricter regulations on development need to be implement, for example banning franking. If larger parcels of natural habitat are not obtain for the San Joaquin kit fox the population will not thrive and become extinct.
...gency of the situation is, you can spread awareness for that particular ecosystem or organism. You could also take part in the “Adopt an Arctic Fox” it’s a program set up by the WWF for not only the arctic fox, but other animals which are endangered. You pay money to adopt the animal for a certain amount of time and the money goes into saving the animal through protests, petitions, treaties and even scientific research. Finally, one of the most contributing and beneficial factors of this cause; the “Take Action” program. Take action is part of a branch of the WWF known as the “Wildlife Action Centre”. It is here where petitions and treaties are sent and enforced to and by government officials. Each year more and more people become interested in the cause and its effects. It is time now for us to take action and make a stand for species that cannot do so themselves.
