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 Larch

Common Larch (<em>Larix decidua</em>) is a deciduous conifer in the family Pinaceae, distinguished among conifers by its seasonal needle drop. Its native range spans Asia (Armenia and Turkey), eighteen European countries, North America (Canada and the United States), and Oceania (New Zealand), encompassing a broad latitudinal range across temperate and boreal zones. The species typically inhabits temperate and boreal forests, often at higher elevations in montane and subalpine zones where it tolerates cold, short growing seasons and well-drained mineral soils. Common Larch is an important timber tree and is widely planted in forestry and as an ornamental species. Its golden autumn foliage is a distinctive feature of mountain landscapes in the Alps and Carpathians. The conservation status of this species has not been formally evaluated by the IUCN. It plays an ecological role in structuring montane forest communities and providing habitat for numerous associated species. Biological traits of this species remain poorly documented in the scientific literature.
