Restoration Ecology

. Beginning in 1936, a group of faculty at the University of Wisconsin-Madison Arboretum undertook the first modern ecological restoration. They surveyed the state, made a list of the native species in existing tallgrass prairies, and replanted those species onto a former horse pasture, restoring the original prairie. This is an example of which approach to restoration ecology?

. An abandoned industrial site on the outskirts of an urban area has soil polluted with toxic chemicals, and essentially no life. The group in charge of improving the site plans to remove the top soil layers to get rid of the toxic chemicals. They will replace it with clean soil. Then, they will choose several species of plants that are attractive and resilient, but not necessarily native. The approach being used to improve this site is best described as

. Restoration of closed landfills often have which type of impact on the community?

. The Cambrian Wildwood, in Wales, is a community-driven project with the goal of restoring native habitats and lost native animals, including the pine marten, red squirrel, wild boar, and beaver. Eventually, it will consist of 7,500 acres (3,000 ha), either purchased or involving partnerships with landowners. The area will have trails and camping areas. Which aspect of the Cambrian Wildwood best defines it as a rewilding project?

. Biological control would likely be beneficial in all of these situations except where

. A person who would probably not favor a plan to restore an ecosystem containing many exotic and introduced species is a person who

. Conservationists have spent much time and effort trying to restore both prairies and wetlands. Which of these statements would most likely refer to a restored prairie, rather than a restored wetland?

. A group of conservationists wishes to restore a degraded agricultural area to its original native prairie. Before determining how the restoration will be done, what is one of the first decisions the group will have to make?

. A scientist involved in a stream restoration project wants to measure the success of the project in terms of its human dimensions rather than its ecological benefits. For example, rather than number of restored stream miles or increased biodiversity, she would measure factors such as how much foot traffic the area would get or how many feet of stream would become accessible to people. According to the concept of biocultural restoration, this change would likely result in

. Complete restoration of ecosystems may become less likely in the future because
