Wiels marsh: a natural but accidental body of water (breakthrough of the water table in 2007) in the heart of the urban center where nature has regained its rights after 10 years of abandonment of the site. Important reed bed sheltering the fauna. Nicknamed Marais Wies, it is not strictly speaking a marsh but is home to all the biodiversity that characterizes a marsh. In danger of being built on. Among the birds you can see here are Eurasian Coot, Little Grebe, Reed Warbler, Grey Heron, Common Sandpiper, House Sparrow, Eurasian Moorhen, Mallard, Common Swift, House Martin, Eurasian Blue Tit, Great Tit, Common Chiffchaff, Greater Whitethroat, Egyptian Goose, Wren and Dunnock.


Français: Marais Wiels: un plan d'eau naturel mais accidentel (percement de la nappe phréatique en 2007) en plein centre urbain où la nature a repris ses droits en 10 ans d'abandon du site. Roslière importante abritant la faune qui va de pair avec ce biotope. Surnommé Marais Wies, il n'est pas un marais à proprement parlé mais abrite toute la biodiversité qui caractérise un marais. En danger de bétonnisation.
