Seaside Amaranth Amaranthus pumilus RafinesqueG2 (Globally rare)  -  Threatened (Federal)  -  Endangered (MD)  -  S1 (Highly state rare)  -  Worcester only  Synonyms: Seabeach Amaranth.

Status:

Seaside Amaranth grows on sandy beaches of the barrier islands along the Atlantic coast. It grows just above the high water mark at the base of sand dunes. In the late 1960s, Seaside Amaranth disappeared from Maryland's barrier islands. The Assateague Island National Seashore website says, "Seabeach amaranth's rediscovery on Assateague occurred in 1998 when a single plant was found by a park biologist. This occasion marked the first time in over 30 years that amaranth had been observed on the island. By 2000 a total of 7 wild plants were discovered. With these 7 plants, the National Park Service, along with other State and Federal agencies, began the hard work of trying to restore a viable population of this threatened species to its native habitat on Assateague. Between 2000 and 2002, offspring from the original plants were planted at many locations along the Maryland portion of the island. Since then, surveys have estimated that the annual amaranth population on Assateague has ranged between 500 and 600 plants." With fewer than 50 populations worldwide, this diminutive plant is truly one of Maryland's hidden botanical gems.

There are 16 records in the project database.
