Common Spike-Rush

<em>Eleocharis palustris</em>, commonly known as the common spike-rush, is a perennial wetland sedge in the family Cyperaceae, broadly distributed across the temperate and boreal regions of the Northern Hemisphere. This species typically inhabits shallow freshwater marshes, pond margins, riverbanks, wet meadows, ditches, and other seasonally or permanently flooded habitats, tolerating a range of water depths and soil conditions. Its geographic range spans Europe, Asia, and North America, extending from subarctic regions southward into subtropical zones. Classified as Least Concern on the IUCN Red List, <em>Eleocharis palustris</em> is among the most ecologically widespread wetland plant species globally. It forms dense stands via rhizomatous growth, providing important cover, nesting sites, and food resources for waterfowl and invertebrates. The plant produces leafless green culms up to approximately 60 cm tall, bearing a single terminal spikelet. As a plant, dietary traits in the animal sense are not applicable. Biological traits such as average individual lifespan, body dimensions in the zoological sense, and body weight remain poorly documented, as these metrics are not typically applied to non-vascular measurements in this genus. The species plays a critical ecological role in stabilising wetland sediments and maintaining water quality.
