Common box

The common box (<em>Buxus sempervirens</em>) is a slow-growing evergreen shrub or small tree with one of the widest distributions of any species in its genus, occurring across Africa, Asia, Europe, North America, and South America. It typically inhabits diverse terrestrial ecosystems, from limestone hillsides and rocky slopes to woodland understories and cultivated gardens. The common box has not been formally evaluated on the IUCN Red List. Long valued in horticulture and topiary, this species is widely cultivated and naturalized far beyond its native range in southern Europe, western Asia, and northern Africa. Its dense, hard wood is among the heaviest produced by any European tree, historically used for woodworking and engraving. The species often forms dense thickets in natural settings, providing important shelter for invertebrates and small vertebrates. Biological traits of this species remain poorly documented in the scientific literature.

Red-billed Duck

Red-billed Duck (Anas erythrorhyncha) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.
