Common Lake Sedge

Common Lake Sedge (<em>Carex lacustris</em>) is a robust emergent sedge in the family Cyperaceae, classified as Least Concern on the IUCN Red List. It is native to Canada and the United States, where it typically grows in grasslands, wetlands, forests, and cultivated landscapes, with a particular association with shallow water and the margins of lakes, ponds, rivers, and marshes. This tall, coarse sedge typically forms dense colonies along shorelines and in wet meadows, providing important habitat structure for waterfowl, amphibians, and invertebrates. Its fibrous root systems and rhizomatous growth help stabilize shoreline sediments and contribute to water quality by filtering nutrients. Common Lake Sedge is a characteristic species of North American freshwater wetland communities and is frequently used in ecological restoration projects targeting riparian and lacustrine habitats. Its stable population and broad North American range support its Least Concern assessment. Biological traits of this species remain poorly documented in the scientific literature.
