Reed beds are officially recognised in France as natural zones of ecological interest in terms of fauna and flora. They are a true reservoir of biodiversity for avifauna (birdlife). This unique environment is protected. They are areas on the edges of pools and marches where reeds constitute the primary vegetation. Reed beds harbour the nests and broods or numerous marsh-dwelling birds and they are effective water purifiers, limiting water pollution. In addition, the species can withstand temperatures down to -20°C.
