Reed beds are natural habitats found in floodplains, waterlogged depressions, and estuaries. Reed beds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reed beds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities. Artificial reed beds are used to remove pollutants from grey water. Burned reeds on flat plain. Time lapse clouds movement. Sunny day. Big large arid wetland. Post-dried field.
