coastal small-reed

Coastal small-reed (Calamagrostis pseudophragmites) is a perennial grass in the family Poaceae, distributed across riparian and coastal habitats in Eurasia, from central and western Europe eastward through Russia and Central Asia to the Far East. Despite database records linking this species to Norway, its actual native range spans riverbanks, gravel bars, flood meadows, and coastal wetlands across the Eurasian continent. It forms tufted stands in disturbed and seasonally inundated soils, often colonising gravel banks following flooding events alongside willow scrub. The genus Calamagrostis encompasses numerous reed grass species adapted to wet, nutrient-poor, and often disturbed habitats. Coastal small-reed can tolerate fluctuating water levels and occasional drought. It is assessed as Least Concern by the IUCN, reflecting its broad distribution and adaptability across its native Eurasian range. In some areas of Europe, populations have declined due to river channelisation, reduced flooding, and loss of natural riverine processes. The species is an indicator of dynamic, naturally managed riparian systems and is used in restoration projects targeting floodplain biodiversity.
