Mainly comprised of high vegetation, dominated by reeds - hence the name - it provides shelter to many birds and insects such as ducks and fireflies. Dead reeds are often the main components when the Jura peat bogs form. It is a very hardy plant, with deep roots which easily acclimate to these marshes. Under certain conditions, reeds can become “invasive”, and spread in the peat bog, “suffocating” the other lower plants. Climate change and air pollution seem to encourage this.
