Habitat & Geographic Range

Cobberas Grevillea

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common corncockle

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.

Cobberas Grevillea

Cobberas grevillea (Grevillea brevifolia) is a low-growing, spreading shrub in the family Proteaceae, endemic to a restricted area in the Cobberas–Tingarringy region of the Victorian Alps and adjacent New South Wales ranges in southeastern Australia. It grows in subalpine to montane heath and rocky outcrops at elevations above 1,000 metres, where it is associated with snowpatch vegetation and exposed rocky ridgelines. The species produces small, narrow leaves and clusters of red and cream spider-like flowers typical of the diverse genus Grevillea, which is one of the largest genera in the Proteaceae family. Flowers are an important nectar source for honeyeaters and insects during the short alpine summer. Cobberas grevillea is assessed as Vulnerable by the IUCN, reflecting its extremely restricted range of only a few square kilometres of suitable habitat and vulnerability to altered fire regimes, climate change—which is shifting snowpack dynamics and vegetation zones upward—and disturbance from feral horses, which damage subalpine vegetation through grazing and trampling. Conservation measures include habitat monitoring within alpine national parks and management of introduced herbivores.

Common corncockle

<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.
