Summary
[edit]DescriptionRNN de Machais 3 - Cliché Vosagus 26-06-2013.JPG |
Français : La tourbière de l'Étang de Machais a été photographiée ici en automne depuis le pierrier oriental qui la domine.
C'est un des derniers lacs-tourbières presque intacts d'Europe occidentale. Le cirque glaciaire très original a été remanié en vallée suspendue barrée par un cône de déjection torrentiel. Il est occupé par un lac acide dystrophe et une tourbière tremblante acidiphile entourée de buttes à Ericaceae & des boulaies sur tourbe. Le microclimat froid a sélectionné des espèces aux affinités arcticoboréales (ou "relictes glaciaires") : la flore comprend notamment le Petit nénuphar, la Myriophylle à fleurs alternes, deux Utriculaires, la Scheuchzérie des marais, la Laîche des bourbiers, le Lycopode inondé, l'Andromède à feuilles de Polium, le Rossolis à feuilles rondes et de nombreuses mousses et hépatiques dont le rare Sphagnum riparium. L'entomofaune nordique est aussi représentée par l'Aeschne subarctique, la Cordulie arctique, le Nacré de la canneberge et le Cuivré écarlate. Réserve naturelle nationale gérée par le Parc naturel régional des Ballons des Vosges. Noter qu'un arrêté interdit la fréquentation de la tourbière centrale.
