Seabeach amaranth had not been seen on Monmouth County beaches since 1899 or elsewhere in New Jersey since 1913, but it was rediscovered in July 2000 in Sea Bright, Monmouth Beach, and Sandy Hook. Biologists are not certain how the species re-colonized Monmouth County beaches; seeds may have blown or floated over from Long Island, washed up from the Carolinas during a storm, or been long-buried in the offshore sands used to widen the beach. To help populations continue to prosper on New Jersey coastal beaches, the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, New Jersey Department of Environmental Protection, and local governments work in partnership to manage and maintain beaches in ways that protect this threatened species and its habitat. Seabeach amaranth grows on Atlantic coastal beaches from New York to South Carolina in areas of bare, shifting sand, and it faces threats from beach erosion, storm damage, seawalls and jetties, sand fencing, beach raking, recreational activities, and insect pests. Its leaves are small and dark green with red edges, its stems are red, seeds begin sprouting in May, plants grow low and spread out, are typically 5 inches in diameter but can be up to 3 feet across, produce tiny yellow flowers that later turn into seed pods, and can grow until late summer.
