An umbrella effect is the protection extended by the presence of an umbrella species to other species in the same habitat. The umbrella species is often either a flagship species whose conservation benefits other species〔Sherman, 2002, 280.〕 or a keystone species which may be targeted for conservation due to its impact on an ecosystem. More generally, an umbrella species determines the area over which conservation occurs. They are often representative of other species in their habitat, being an easily observable and known species. ==Example== A good example of an umbrella species and its impact is summed up by Kimberly Andrews, a University of Georgia doctoral student at the Savannah River Ecology Laboratory: "Protecting a species like the canebrake has practical applications, as protection measures would have broad environmental value because of an umbrella effect. That is, protecting the rattlesnakes would ensure protection of other wildlife species that use the same habitats but are less sensitive to development or require fewer resources."〔Gibbons, 2007.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Umbrella effect (ecology)」の詳細全文を読む スポンサード リンク
