This “Elwha Ecosystem Restoration Project ” is the largest dam-removal undertaking in U.S. history. This project could serve as an inspiration and a model for similar enterprises in other parts of the country and in the world. Both dams, constructed to provide electricity for a paper mill (funded by Japanese capital) in the city of Port Angeles, were built without fish ladders, which allow salmon to navigate through dams. The dams’ removal had been proposed as far back as the 1970s, but was resisted by many of the local communities. Finally, a U.S. congressional act passed in 1992 paved the way for the U.S. government to acquire the dams and remove them in order to restore the river’s ecosystem. This paper tries to elucidate the core reason for dismantling the dams through reviewing degradation of the watershed environment and the prospects for the restoration of both natural and human related conservation.}, pages = {17--39}, title = {ダム撤去による河川生態系回復の試み : エルワ川ダム撤去に至る経緯}, volume = {第24巻}, year = {2012}, yomi = {ムラカミ, キミヒサ} }
