chapter 13 chapter in review
1.) Yosemite was authorized by Lincoln in the middle of the Civil War to protect its resources from the settlers. Yellowstone was the first national park because of U.S. Grant, its purpose was to protect the curious nature of its geysers.
2.)Pollution and noise from snowmobiles put wildlife, vegetation, and park workers at risk. They also leak gas and oil. Off road vehicles compact soil and cause erosion. Air pollution and acid rain damage all ecosystems.
3.) The reintroduction of wolves into Yellowstone makes neighbors of the park nervous that their are these dangerous predators around even though they stablize prey populations.
4.) Areas protected have been growing on a global basis for 50 years. The areas where growth is most prevolent are Asia, North America, and Latin America.
5.) The ideal MAB must have a core zone where their is limited human interference. A buffering zone around that where a couple human influences can exist and then a multiple use area on the outer ring.
6.) Wilderness is an area of undeveloped land affected primarily by the forces of nature, where a man is a visitor who does not remain, it contains ecological, geological, or other features of scientific or historical value.
7.) Wetlands provide food and a habitat for a lot of species, at least a third of endangered species spend some time in these wetlands. They are threatened by our discharge and dumping into them. The Clean Water Act was developed to stop this.
8.) The tropical forest and the grassland have been most effected by humans. We have cut done billions of trees in these forests and lost numerous species because of it. Overgrazing takes place in our grasslands.
9.) A landscape is the factors that make up a geographic area such as grade, materials, location. I live on an island, it is a big rock that sticks out of the water, this is evident because my house is on a rock.
10.) Restoration means to bring something back to a former condition(the forests in our country)
Rehabilitation refers to attempts to rebuild elements of structure or function in an ecological system without necessarily achieving restoration(florida everglades)
Remediation is a process of cleaning chemical contaminants from a polluted area by physical or biologal methods(St. Lawerence River)
Reclamation describes chemical or physical manipulations carried out in severely degraded sites such as open pit mines or large scale constructions(SMCRA)
Recreation attempts to construct a new biological community on a site so severly disturbed that there is virtually nothing left to restore(ponds in the clean water act of 1977)
