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 Tiger Beetle

<em>Cicindela campestris</em>, the common green tiger beetle, is a predatory beetle in the family Cicindelidae, recorded from Belgium, Denmark, Norway, and Sweden. It is classified as Near Threatened on the IUCN Red List, reflecting population declines linked to habitat loss, particularly the loss of open sandy heathlands, coastal dunes, and dry grasslands across its European range. This beetle is one of the fastest-running terrestrial insects and is an active, visual predator that pursues invertebrate prey with speed and agility. It is characterized by vivid metallic green elytra spotted with cream or white, providing camouflage against sandy substrates. Adults are typically 12–15 millimeters long and are found on bare, sun-exposed sandy ground. Larvae are ambush predators living in vertical burrows in sandy soil, capturing passing insects. The species requires warm, sparsely vegetated sandy habitats that are increasingly rare due to land-use change, scrub encroachment, and development. Conservation of heathland and dune habitats is critical for maintaining viable populations of this Near Threatened species.
