Threatened species in Switzerland, standing 2010

43% of mayflies, 40% of stoneflies and 51% of caddisflies found in Switzerland are included in the Red Lists of threatened species on the basis of the IUCN criteria. These represent a total of 47% of the 499 evaluated species, for which sufficient data are available; a further 15% (71 species) are near threatened. The most severely threatened species are those found in rivers located on plains (river straightening, altered water flow dynamics, water quality) and, in part also, in small lakes and ponds and in meadow creeks (pollutant contamination, unnatural conditions). The revised Red List of mayflies of Switzerland presented here replaces the first edition.
