coast club-rush

Coast club-rush (Schoenoplectus subulatus) is a tall, emergent sedge in the family Cyperaceae, found in coastal and estuarine wetlands throughout tropical and subtropical regions of Africa, Asia, the Middle East, and the Americas. It grows in brackish and freshwater tidal marshes, mangrove margins, river mouths, and lagoons, often forming dense stands in nutrient-rich mudflats. The triangular stems are characteristic of the Schoenoplectus genus, which includes the common bulrush. Like other bulrushes, coast club-rush provides dense nesting habitat for rails, herons, and bitterns, as well as food in the form of seeds and stems for waterfowl. It plays an important ecological role in coastal nutrient cycling, sediment trapping, and shoreline stabilisation. The IUCN assesses the species as Least Concern, reflecting its wide distribution across tropical and subtropical coastal regions globally. In some areas, it competes with other emergent vegetation, and its stands can be dense enough to impede water flow in managed wetlands. It is used in some regions for thatching and traditional basketry.
