Coast Sedge

Coast sedge (Carex exilis) is a slender, tufted perennial sedge in the family Cyperaceae, native to boggy and peaty habitats in northeastern North America, from Newfoundland and Labrador south through New England and the Great Lakes region to the mid-Atlantic states. It grows in sphagnum bogs, fens, moist sandy peats, and the margins of coastal plain ponds—habitats characterised by low nutrient availability, high moisture, and acidic soils. The species produces narrow, grass-like leaves and small, inconspicuous flower spikes typical of the vast Carex genus, which is one of the largest and most ecologically diverse plant genera on Earth. Coast sedge is assessed as Least Concern by the IUCN, reflecting its distribution across a range of protected coastal plain and boreal wetland habitats in northeastern North America. The coastal plain ponds it inhabits are considered globally rare ecosystems of high botanical interest. Like many sedges, coast sedge provides important habitat structure for invertebrates, breeding birds such as sedge wrens, and small mammals in wetland communities.
