Habitat & Geographic Range

Gewöhnliche Kornrade

Habitat

Found across multiple habitat types including montane grasslands and shrublands, tropical and subtropical moist broadleaf forests, and temperate coniferous forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Lesotho), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Gewöhnliche Kornrade

<em>Agrostemma githago</em>, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.

Zusammengedrückte Binse

<em>Juncus compressus</em>, commonly known as the Compressed Rush, is a perennial herbaceous plant in the family Juncaceae, native to temperate regions of Europe and introduced or naturalised across parts of North America. The species typically grows in moist to wet habitats including grasslands, marshes, riverbanks, ditches, and the margins of cultivated land, tolerating periodic flooding and a wide range of soil conditions from loamy to clayey substrates. Its stems are characteristically flattened or compressed in cross-section, a distinguishing feature that gives the plant its common and scientific names. Reproductively, <em>Juncus compressus</em> bears small, brownish flowers arranged in loose, terminal inflorescences, and produces capsule-type fruits containing numerous tiny seeds dispersed by water and wind. The species has a broad geographic distribution across at least seven European countries including Belgium, Denmark, Finland, and Ireland, as well as Canada and the United States in North America. As a primary producer, it plays an ecological role providing cover and food resources for invertebrates, waterfowl, and small mammals in wetland ecosystems. Currently assessed as Least Concern by the IUCN, populations appear stable throughout most of its range, though wetland drainage and agricultural intensification pose localised threats.
