Abstract: An integrated analysis of landscape change in the alpine zone of Sagarmatha (Mt. Everest) National Park, Nepal, is presented based on the results from five separate research expeditions conducted between 1984 and 2004. Research results indicate that alpine ecosystems (4,000–5,200 m) within the Imja and Gokyo valleys have been significantly impacted during the past twenty to thirty years as a result of poorly controlled tourism. Impacts within the alpine zone include the overharvesting of fragile alpine shrubs and plants for expedition and tourist lodge fuel, overgrazing, accelerated erosion, and uncontrolled lodge building. Evidence suggests that similar scenarios of landscape change in the alpine zone are occurring elsewhere around the Everest massif as the result of adventure tourism. This article stresses that the alpine zone is a comparatively neglected landscape that is in need of greater protection, conservation, and restoration involving integrated, applied research to the clarification of problems, the design of remedial projects, and monitoring of their impacts. “Community-based Conservation and Restoration of the Everest Alpine Zone,” a Sherpa-led project established in May 2004, is provided as an example of how the paper's research results are currently being utilized by local communities.
