River Pearl PLUS the label for untouched Swiss waters

Let’s preserve natural rivers and streams!

Switzerland’s waters are in a perilous situation. Most streams and rivers have been straightened or canalised, or else fragmented by dams. Less than 4% are still in their natural state.

We must value and protect these last remaining untouched streams and rivers! Not only are they important habitats for native animals and plants – especially for threatened species. They are also important recreational areas for us humans.

With the River Pearl PLUS label, we recognize untouched streams and rivers, as well as the commitment of local people.

Mature trees with spreading canopies on the water’s edge became a rare sight. When planting, it is important to allow space for these future trees. (Thur inland canal (c) T. Stäheli / WWF Switzerland)

From river network to life network – why riverbank vegetation is vital for living water bodies

Anyone walking along many of Switzerland’s streams and rivers today will see open, well-maintained banks – free of bushes and trees. No shade, no rustling leaves, no twittering birds. What looks neat and tidy is often a sign of ecological poverty, though. That's because flowing waterways are more than just clean water flowing through a channel: they are diverse habitats embedded in overgrown, structurally rich riverbanks.
