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-cypress

<em>Cupressus sempervirens</em>, the common cypress, is a coniferous evergreen tree in the family Cupressaceae. Native to the Mediterranean region and widely distributed across Europe, Africa, Asia, North America, Oceania, and South America, this species typically thrives in temperate broadleaf and coniferous forest habitats within the Palearctic realm. The common cypress is characterized by its distinctive columnar or pyramidal growth form, with dark green, scale-like leaves arranged in dense, flattened sprays. It often grows on well-drained, rocky or alkaline soils and typically tolerates drought and heat, making it well adapted to Mediterranean climates. The tree produces small, rounded cones that take approximately two years to mature. <em>Cupressus sempervirens</em> is widely cultivated as an ornamental tree and windbreak, and its durable, aromatic wood has historically been valued for construction and furniture. This species is also associated with funerary traditions in many Mediterranean cultures. Its conservation status is assessed as Least Concern, reflecting its broad range and stable populations across multiple continents.
