Acker-Schachtelhalm

The Common Field Horsetail (<em>Equisetum arvense</em>) is a vascular plant belonging to the genus Equisetum within the family Equisetaceae. It is one of the most widespread and recognisable of the horsetail species, characterised by its jointed, hollow stems and whorls of slender branches. The species is found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, spanning the Afrotropic and Palearctic biogeographic realms. Its geographic distribution is exceptionally broad, encompassing Africa including Mauritius, Asia including Iran and Taiwan, nine European countries, North America including Canada, Mexico, and the United States, Oceania including Australia and New Zealand, and South America including Brazil. <em>Equisetum arvense</em> is assessed as Least Concern on the IUCN Red List. The plant often colonises disturbed soils and is considered a persistent weed in agricultural settings. Biological traits beyond its distinctive morphology remain poorly documented in the scientific literature.
