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.

Rusty-faced Parrot

A medium-sized parrot of the high-altitude cloud forests and Andean slopes of Colombia and Venezuela, rusty-faced parrots have green plumage with a distinctive orange-rufous face and forehead. They inhabit humid mountain forests between 1,500–3,000 meters and are little studied due to their remote, steep habitat. Listed as Vulnerable due to ongoing deforestation of Andean cloud forests. They move seasonally with food availability across forested ridges.
