Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Broad-ringed White-eye

The Broad-Ringed White-Eye (Zosterops poliogastrus) is a species in the genus Zosterops. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical grasslands and savannas within the Afrotropic biogeographic realm.

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.
