coast amaranth

Coast amaranth (Amaranthus pumilus) is an annual herb in the family Amaranthaceae, native to the Atlantic and Gulf coasts of the eastern United States, where it once grew on coastal foredunes, beach strand, and shell-hash substrates above the high tide line from New York south to South Carolina. It is a low-growing, fleshy plant with small, rounded leaves and inconspicuous green flowers typical of the genus. Coast amaranth is assessed as Extinct in the Wild by the IUCN, as it has not been reliably documented from wild populations since the mid-20th century; the last confirmed collections date to the 1960s. The species' decline and likely extinction resulted from intense human pressure on Atlantic coastal habitats through shoreline development, beach stabilisation, vehicular traffic on beaches, and increased storm frequency disrupting pioneer dune vegetation. It is federally listed as Threatened in the United States, though this listing predates confirmed extinction in the wild. A small number of ex-situ accessions may exist in botanical garden collections. Genetic material and seed banking efforts represent the only remaining conservation options for this critically reduced species.

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.
