Common Tussock Sedge

<em>Carex stricta</em>, commonly known as the common tussock sedge or tussock sedge, is a clump-forming perennial sedge in the family Cyperaceae native to wetland habitats of eastern North America. It is distributed widely from Nova Scotia and Quebec south to Florida and westward to the Great Plains, occurring in freshwater marshes, forested swamps, wet meadows, pond margins, and other seasonally to permanently flooded habitats. A characteristic feature of this species is the formation of large, elevated tussocks — densely rooted, mound-like structures that can reach 60 centimeters or more in height and may persist for decades, providing elevated microsites above standing water for other plants and animals. <em>Carex stricta</em> typically produces narrow, grass-like leaves and elongated, cylindrical spikes bearing small brown pistillate and staminate flowers in spring. The tussocks are ecologically significant, offering nesting sites for birds such as marsh wrens and serving as refugia for invertebrates, amphibians, and small mammals during flooding. The species is currently assessed as Least Concern by the IUCN, with stable populations across its broad native range. Conservation concern is focused on wetland degradation and drainage. Biological traits such as average individual lifespan, above-ground biomass, and precise leaf dimensions remain variable across populations and are poorly documented at the individual level.
