onderreed
Onderreed (Dutch for "under reed") is a term used in wetland ecology to describe the submerged components of reed beds, including rhizomes, roots, and the lower portions of stems that remain below the water surface. The concept emphasizes the underwater structure that supports the above-water canopy and overall bed stability.
In typical stands of common reed (Phragmites australis), onderreed comprises the rhizome network and below-water shoots
Ecologically, onderreed contributes to sediment stabilization, nutrient cycling, and habitat provision for a range of aquatic
Onderreed is most commonly observed in temperate wetlands across Europe and parts of Asia, where reed beds
In research and restoration practice, onderreed is considered when designing wetlands and reestablishing reed stands, because
