The Camargue environments are very strongly marked by salt and only the banks of the river and its alluvial ridges escape this influence and develop much more luxuriant vegetation. This wood, which we call ripisylve, includes white poplars, ash trees and elms. The banks of the river are colonized by amorphous, bulrushes, reeds and marsh irises. This environment is also home to many species of birds and mammals that find refuge there.
