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 Barrel Cactus

Coast barrel cactus (Ferocactus viridescens) is a stout, ribbed cactus in the family Cactaceae, native to coastal sage scrub and chaparral communities of extreme southern California and northern Baja California, Mexico. It grows on rocky slopes, canyon walls, and coastal bluffs within a few kilometres of the Pacific coast, favouring thin soils and south- or west-facing exposures. This barrel cactus reaches up to 1 metre in height and diameter, bearing dense clusters of stout red or pink spines and yellow to greenish-yellow flowers that bloom in late spring and summer. Fruits are yellow and edible when ripe, historically used as food by Indigenous Kumeyaay people. The coast barrel cactus is threatened by illegal collection for the horticultural trade, urban sprawl around San Diego, and invasive grasses that increase fire frequency in chaparral. It is assessed as Least Concern by the IUCN, but populations in California are considered vulnerable due to limited range. The species is legally protected under the California Endangered Species Act and the Convention on International Trade in Endangered Species (CITES).
