Habitat & Geographic Range

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.

Cona Paa Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

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.

Cona Paa Frog

<em>Nanorana conaensis</em>, commonly known as the Cona Paa Frog, is a small amphibian in the family Dicroglossidae, a diverse group of frogs distributed across South and East Asia. The genus Nanorana is characteristic of high-elevation Himalayan and Tibetan Plateau habitats, and <em>Nanorana conaensis</em> is presumed to occur in the Cona region of southeastern Tibet, China, where it likely inhabits cold freshwater streams, moist alpine meadows, and the margins of wetlands at considerable elevation. Like other paa frogs, it is presumed to be a generalist carnivore, typically consuming invertebrates such as insects, worms, and small crustaceans detected by sight near water. The species is currently classified as Data Deficient by the IUCN, reflecting the limited biological and distributional information available. Geographic range boundaries, population size, and population trend data remain unconfirmed, partly due to the remote and politically restricted nature of its presumed habitat on the Tibetan Plateau. Biological traits including average body size, lifespan, reproductive seasonality, and clutch size remain poorly documented in the primary scientific literature. Conservation threats potentially include habitat degradation from infrastructure development, climate-driven changes to alpine hydrology, and human disturbance in high-altitude wetland ecosystems.
