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.

Coast Purple Tip

Coast purple-tip (Colotis erone) is a butterfly in the family Pieridae, subfamily Colotinae, native to coastal and wooded savanna habitats of sub-Saharan Africa, occurring in eastern and southern Africa from Kenya and Tanzania south to Mozambique and South Africa. Like other Colotis species, males have striking wing-tip markings—in this case a vivid purple or lilac patch on the forewing apex—while females are more cryptically patterned. Larvae feed on plants in the family Salvadoraceae or Capparaceae, typical host families for the genus. Adults are fast-flying and typically found along woodland margins, coastal thickets, and scrub habitats near the coast. The genus Colotis is distributed across Africa and Asia, with many species restricted to specific host plants and habitat types. Coast purple-tip is assessed as Least Concern by the IUCN, with populations distributed across suitable coastal and woodland habitat in eastern and southern Africa. Like many invertebrates, it is sensitive to habitat quality and the availability of its larval food plants.
