Clustered Sedge

Carex glareosa, the clustered sedge or gravel sedge, is a perennial sedge in the family Cyperaceae distributed across the circumpolar Arctic and subarctic zones of the northern hemisphere, growing in coastal and inland wetlands, salt marshes, brackish meadows, mudflats, gravelly tundra, and low-lying areas subject to periodic flooding. The species forms dense tufts or loose colonies, producing narrow, grass-like leaves and small spikelets characteristic of the genus Carex. C. glareosa is adapted to saline and brackish conditions in coastal habitats, as well as to freshwater wetlands in more continental settings. Like other Arctic sedges, it is an important component of tundra and wetland plant communities that provide habitat and forage for migratory waterfowl, shorebirds, and Arctic mammals. The species is listed as Vulnerable by the IUCN, with concern focused on the impacts of climate change on Arctic and subarctic wetland habitats, where rising temperatures, permafrost thaw, altered hydrology, and increased shrub encroachment threaten specialized wetland plant communities.
