Swiss Alps Jungfrau-Aletsch, Switzerland
This heritage site is located in the northeastern part of the Valais region in southwestern Switzerland. The Jungfrau, Aletsch Glacier, and Bietschhorn Peaks were added to the list in 2001, and the expansion in 2007 increased the core protection area from the original 539 km2 to 824 km2. The heritage site is a good example of the topography of the Alps, and it includes the most heavily eroded areas of the mountains and the largest glaciers in Eurasia. The conservation area covers a variety of ecosystems, and the continuous ladder-like sequence of habitats was caused by climate change associated with the retreat of the glaciers. Because of its outstanding natural beauty and because it contains a wealth of information about the development of mountains, glaciers and climate change, the heritage sites are prominent and have universal value.
