Compressed Spike-Rush

<em>Eleocharis compressa</em>, commonly known as the Compressed Spike-Rush, is a perennial sedge-like plant in the family Cyperaceae, endemic to the eastern and central United States. It typically inhabits calcareous wetlands, prairie fens, wet meadows, and the margins of streams and lakes, favoring sites with shallow water or saturated soils that are often rich in calcium and magnesium. The species is characterised by strongly flattened, wiry stems and small, solitary spikelets at the stem tip, features typical of the genus Eleocharis. Like other spike-rushes, <em>Eleocharis compressa</em> is a photosynthetic primary producer with no true leaves, relying entirely on its green stems for carbon fixation. It provides important microhabitat for aquatic invertebrates and nesting cover for ground-foraging birds in fen communities. Currently assessed as Least Concern by the IUCN, the species faces pressure from wetland drainage, agricultural runoff, and the alteration of hydrology in prairie landscapes. However, it persists across a sufficient portion of its range to maintain a stable conservation status. Biological traits such as average lifespan, reproductive output, and growth dimensions remain poorly documented relative to more commercially studied wetland species, though it is typically a slow-growing, long-lived perennial.
