Inscrite sur la liste rouge et class\u00e9e comme vuln\u00e9rable, elle d\u00e9pend de prairies de montagne ensoleill\u00e9es, ouvertes, vari\u00e9es et riches en fleurs, situ\u00e9es \u00e0 la limite sup\u00e9rieure de la for\u00eat. Pour ne pas \u00eatre emport\u00e9e par les eaux de fonte au printemps, la chenille choisit de petites buttes dans les prairies pour se m\u00e9tamorphoser.<\/p>\n

Le papillon souffre autant de la surexploitation que de la sous-exploitation agricole. Dans les prairies exploit\u00e9es intensivement, le sol est souvent aplani, ce qui ne laisse plus de petits endroits prot\u00e9g\u00e9s pour les chenilles. Si ces prairies sont ensuite enti\u00e8rement fauch\u00e9es, ou fauch\u00e9es avant la p\u00e9riode de vol du papillon, il ne trouve plus de fleurs pour se nourrir. Dans les prairies peu ou plus du tout exploit\u00e9es, des buissons et des arbres gagnent du terrain et recouvrent progressivement les zones ouvertes et ensoleill\u00e9es dont le papillon a absolument besoin. Une gestion adapt\u00e9e \u00e0 ses besoins est donc essentielle pour soutenir l\u2019esp\u00e8ce et assurer sa survie \u00e0 long terme.<\/p>\n

Kurzbericht<\/strong>
Die Unterart des Sudeten-Mohrenfalters Erebia sudetica inalpina kommt einzig im Raume Grindelwald vor, zwischen der Grossen Scheidegg und Hintisberg. Er steht auf der Roten Liste und wird als verletzlich eingestuft. Sein bevorzugter Lebensraum sind sonnige, offene, struktur- und bl\u00fctenreiche Bergwiesen im Waldgrenzbereich. Um im Fr\u00fchling nicht vom Schmelzwasser weggesp\u00fclt zu werden, verpuppt sich die Raupe auf kleinen H\u00fcgeln in den Wiesen. Problematisch f\u00fcr den Sudeten-Mohrenfalter sind sowohl landwirtschaftliche \u00dcber- als auch Unternutzung: \u00dcbernutzte Wiesen sind oftmals planiert und bieten den Raupen keinen Schutz. Werden die Wiesen zudem vollst\u00e4ndig oder vor der Flugzeit des Falters gem\u00e4ht, findet er keine Bl\u00fcten mehr. In unternutzten oder nicht mehr genutzten Wiesen \u00fcberwuchern B\u00fcsche und B\u00e4ume die offenen, sonnigen Fl\u00e4chen, auf die die Falter angewiesen sind. Eine angepasste Bewirtschaftung an die Bed\u00fcrfnisse des Sudeten-Mohrenfalters ist zwingend n\u00f6tig, um die Art zu f\u00f6rdern und ihr Bestehen l\u00e4ngerfristig sicher zu stellen.<\/p>

Massnahmen<\/strong>
In Zusammenarbeit mit dem Amt f\u00fcr Naturf\u00f6rderung (Kt. Bern), den Bergschaften und mit Hilfe von Freiwilligen werden gezielte Entbuschungsaktionen im Raum Grindelwald durchgef\u00fchrt.<\/p>
