No, the designation as natural World Heritage has no influence on the status or the use regulations. The latter are laid down according to the existing municipal, cantonal and national requirements.

The World Heritage region Swiss Alps Jungfrau-Aletsch is the largest ice-covered area in the whole alpine region; with 350 km2 inside the Perimeter it is the biggest ice surface in the Alps. Climate change and glaciers decline are therefore the main issues in the region. For more information, go to Pro Natura Aletsch and the chapter "Glaciology – Approach towards 3500 years of glaciers history" by Heinz Zumbühl and Hanspeter Holzhauser in the book "Welt der Alpen - Erbe der Welt. Jungfrau-Aletsch-Bietschhorn" published in 2007. To order, go to the online shop.

There is no extension scheduled any more. The region’s development came to a close with the in June 2007 confirmed extension to the Grimsel and the Bluemlisalp by the UNESCO World Heritage Committee. It is however possible that in approximately 10 years from now corrections to the Perimeter‘s boundaries could be necessary to one or more places. These modifications must be submitted to the UNESCO World Heritage Committee.

The UNESCO World Heritage area is 824 km2 large and represents  2% of Switzerland’s global territory (41'293 km2) or approximately the size of the canton of Jura (838 km2).

UNESCO stands for United Nations Educational, Scientific and Cultural Organization, UNESCO has 192 Member States. UNESCO is one of the 16 legally independent special organisations of the United Nations and has its headquarter in Paris. UNESCO’s task is to preserve the cultural and natural goods which are of “Outstanding Universal Value“, as stated in the World Heritage Convention.

In 1972 UNESCO adopted the „Convention concerning the Protection of the World Cultural and Natural Heritage“ (World Heritage Convention). To date, 184 States became party to the Convention. It is the most meaningful international tool, designed by the community of nations to preserve their cultural and natural heritage. The criteria for the admission on the „World Heritage List“ can be found under: criteria

UNESCO does not give any funds to the designated World Heritage Sites. UNESCO confers only the very sought-after UNESCO World Heritage Label.

An international UNESCO Committee decides, once a year, which new sites will be inscribed on the World Heritage List. Is a property inscribed, the State party is committed to protecting the natural or cultural good owning an „Outstanding Universal Value“. This commitment includes self-financing and securing the site through protective, conservative and use measures. 

The UNESCO World Heritage Swiss Alps Jungfrau-Aletsch-Bietschhorn Organisation was restructured to avoid redundancies: On the 11. December 2007 the Perimeter municipalities founded the new Foundation UNESCO World Heritage Swiss Alps Jungfrau-Aletsch. On Jan.1 2008, the Foundation was operative. Members are the 18 municipalities of the Perimeter’s Valais side and the 8 municipalities on the Bernese side. >> Foundation Council
