Seabeach amaranth (Amaranthus pumilus) is a federally threatened plant species that is vulnerable to both man-made and natural disturbances. Large populations of seabeach amaranth (from 3,000 to 5,000 individuals per year) grew at Cape Hatteras National Seashore in the late 1980s, but the populations subsequently declined and none have been found since 2005. Park staff survey for the species annually because seabeach amaranth is a pioneer species and populations are highly variable. In 2018, Staff spent approximately 44 hours surveying for amaranth, covering roughly 44 lineal miles of potential beach habitat by foot and utility terrain vehicle (UTV). No amaranth was found anywhere within the survey areas.
