Callie, a shy 15-year-old girl, is admitted to Sea Pines (“a residential treatment facility”) after a school nurse discovers that she's been self-mutilating. At Sea Pines she meets six other girls who are dealing with austere problems of their own, which range from anorexia to substance abuse. Callie refuses to speak to anyone, but after a while, she realizes that she wants help and starts to talk...…
William Cronon, Changes in the Land, is an ecological history of colonial New England in which he analyzes the ecological consequences of the European invasion. Cronon took an interdisciplinary approach to his research on the region, utilizing a vast array of sources, which enabled him to construct a detailed analysis on how the ongoing reciprocal relationship between the environment, Indians, and European settlers brought about drastic ecological changes and how these changes in turn limited the choices available to the people. Cronan argues that much of the change to the ecosystem of colonial New England resulted from the Colonists ' contrasting view of property and essentially, their involvement in a capitalist economy. The following review contains a small survey of the books contents, including the evidence Cronon uses to support his argument, my evaluation of both, along with some questions that were raised upon reading Brian Donahue 's, “Environmental Stewardship and Decline in Old New…
The text “Changes In The Land” by William Cronon is an accurate depiction of the alteration in ecology in New England during the colonial period. The book carefully describes how the Indians had been influencing their environment in a significant yet sustainable manner many years before the Europeans came to colonize New England. Cronon explains the idea of how commodity shaped the differences between western and native land practices. He has the ability to tell this story from both perspectives in a correct and clearly understandable fashion. He illustrates that the misunderstanding between two races eventually led to the fall of the Indians. Cronon constantly calls upon many records and scientific reports to support his arguments on the…
Invasive species are organisms that infiltrate ecosystems that are unable to support their alien lifestyle and diet. Their initial invasion may seem inconsequential and, frankly, insignificant at first, but their numbers will quickly grow and multiply, so much that the future outcome takes a drastic turn for the worst. Florida, in particular, has been attacked by numerous invasive species because of its accessibility to foreign cargo and material. The Burmese python, Cuban treefrog, and lionfish are just a few of the infamous invasive species growing in prominence throughout Florida. Even though these species seem incredibly different, they have one thing in common - an ability to tear down entire ecosystems by just being alive! It is important…
2. How did their “occupation” influence the natural development of the landscape? How did they change the land they occupied?…
Mann writes about how the Indians shaped and altered their land to suit their needs. The Indians used fire and rich soil, “black earth”, to do so. Mann writes “ Indians were the Keystone species of American ecosystems...removing them, results in a relatively significant shift…”. A keystone Species is a species that “affects the survival and abundance of many other species”. Evidence suggests the “black earth” covers ten percent of Amazonia. When the Indians were populous, they kept down the populations of animals by hunting them. Once diseases killed the Indians, there was a great boom in the animals populations and their now vast habitats. This provides a reason for Hernando de Soto’s expedition not encountering any bison, while later, when the French traveled down the Mississippi hey encountered bison.…
An increasing human population has severely altered the ecosystem of Louisiana’s coastline. Human influence on the wetlands has diminished it 's size by thousands of square kilometers. Saltwater inundation has deteriorated much of the freshwater plant life and levees built to control the flow of the Mississippi river have prevented any natural restoration. This has caused a reduction in the chance of forming new land while the current land is disappearing into the sea.…
Selective Indian burning thus promoted the mosaic quality of New England ecosystems, creating forests in many different states of ecological succession. In particular, ‘the edge effect’ enlarged edge areas that actually raised the total herbivorous food supply; they not merely attracted game, but helped create much larger populations of it. The land became more open with fewer weeds, and allowing more sunlight to promote growth. These open areas made hunting easier, sometimes with the intentional planting of shrubs lining a pathway for herds to fall into a trap of a few hundred hunters waiting on the other side.…
The kudzu problem, also known as the invasive species Pueraria montana var. lobata, currently rages across the Southern US, drowning out the native vegetation and covering anything in its way, including human architecture. However, the kudzu faces the same upcoming trials as we do—climate change. Will the kudzu, having already stood the test of migration, handle the coming climate shift just as well? To answer this question, we examine the three characteristics of kudzu that allow it to succeed as an invasive species, outcompeting both native species and human landowners, and how these same characteristics…
The Sonoran desert of southern Arizona is under severe threat due to a non-native species: 1 buffelgrass (Cenchrus ciliaris). Buffelgrass, or African foxtail grass, is native to regions of Africa, southern Asia, Iran, and the extreme south of Europe. 2 It is a perennial grass that grows to about 50 cm tall with linear leaves. Buffelgrass was first introduced to Arizona, Texas, and Sonora, Mexico in the 1930’s as a means to feed cattle and prevent soil erosion. Unfortunately, many ranchers in Sonora, Mexico are still using this invasive grass as a means to feed their cattle and going as far as planting and irrigating the buffelgrass. If buffelgrass is allowed to flourish in the American southwest, we can witness the end of the beautiful ecosystem…
California’s Native Americans flourished for 15,000 years. They were nomadic hunters but also had great gathering skills. They lived their lives free from regime. The population was dense, culturally diverse, and the languages in that state were vast, hundreds of tribes and bands coexisted. Even though the land was used and manipulated to enhance…
In spring, a season which brought massive runs of shad, alewives, herring, and mullet from the ocean into the rivers, Indians in Florida and elsewhere along the Atlantic coastal plain relied on fish taken with nets, spears, or hooks and lines. In autumn and winter—especially in the piedmont and uplands—the natives turned more to deer, bear, and other game animals for sustenance. Because they required game animals in quantity, Indians often set light ground fires to create brushy edge habitats and open areas in southern forests that attracted deer and other animals to well-defined hunting grounds. The natives also used fire to drive deer and other game into areas where the animals might be easily dispatched. Because the region’s climate offered a long growing season and generally plentiful rainfall, southern Indians developed a complex system of agriculture based primarily on three crops: corn, beans, and squash. To clear farmland, the natives used fire and stone axes to remove smaller brush and timber. They then stripped the bark (a process known as girdling) from larger trees so that they sprouted no leaves and eventually died. Native farmers (primarily women) then planted corn, beans, and squash together in hills beneath the dead and dying trees. By all accounts, the three crops, known in some cultures as “the three sisters,” usually did well under such conditions. Beans helped replace nitrogen taken from the soil by corn; cornstalks provided “poles” for the beans to climb; and broad-leaved squash plants helped cut down on weed growth and erosion. Farming seems to have allowed native populations to increase in the millennium before European contact. Some of the larger native cultures probably numbered in the tens of…
The abundance of native tallgrass prairies have been declining for the past century, and are being replaced by urbanized landscaping. As it has been studied, the area of tallgrass prairies have declined over 82% since the 1800s (Larsen et al. 2003).Tallgrass prairies harbor more plant and animal biodiversity, compared to urban landscaping. Thus, the conservation and preservation effort for prairies should increase, in order to maintain this biodiversity. Tallgrass prairies can be protected by either grazing or fire (Larsen et al. 2003). In addition to grazing, or fire, protecting prairies can also be done by conserving the landscape area and elimination any human land use and disturbances to be done on those prairies. If there is not much effort put into maintaining these environments, the prairies will decline more and more as time goes by, which can eventually disturb the populations of some native species. The declining of tallgrass prairies is also disturbing the population of some native species. Introduced species might not be affected by the habitat changes, in which those changes might be into their advantage, and they are able to adapt to their new habitat. This can result in allowing the introduced species to overcome the population of native species, eventually causing a major diversity changes.…
In many opinions, invasive species becoming introduced to a different environment is not deemed acceptable. With many situations incorporating these species, they are sought to be pests, only trying to make lives difficult for others. Many also have come to believe, from experience, that these insidious species cause harm to the environment of which they are newly exposed to. The businesses and/or government agencies that bring invasive species to a new environment must consider many measures before transferring and following through with brings the species forth to a new location. With careful considerations of transportation, other natural predators, the actual environment and the sole purpose, the business and/or government agency must vigilantly take into consideration the actions it is about to partake in.…
An invasive species such as the zebra mussel, invaded the Great Lakes of America in 1988. They were brought in by seagoing vessels that emptied their ballast water as they got in the port, the zebra mussels had hitched a ride in the water taken in in the ballast before the ship left port in the Caspian and Black seas. By 2010 these muscles and colonized the waters in over 30 US states spreading like wildfire. Invasive species have a huge impact on their nonnative environment, the zebra mussel clogs and take pipes at factories in water treatment facilities that can degrade docs and ruin fishing gear. But it’s not the only invasive species after reading this chapter I decided to look up a little more online about invasive species, it seems that…
