Endangered and Threatened Wildlife and Plants; Determination of Endangered Status for Astragalus holmgreniorum (Holmgren milk-vetch) and Astragalus ampullarioides (Shivwits milk-vetch)

Краткое содержание

We, the Fish and Wildlife Service (Service), have determined endangered status under the Endangered Species Act (Act) of 1973, as amended, for two perennial herbs--Astragalus holmgreniorum (Holmgren milk-vetch) and Astragalus ampullarioides (Shivwits milk-vetch). Three small populations of A. holmgreniorum exist in Washington County, Utah, and adjacent Mohave County, Arizona. Five small populations of A. ampullarioides exist in Washington County, Utah. Significant portions of the habitat of both species are subject to disturbance from urban development, off-road vehicles (ORVs), grazing, displacement by exotic weeds, and mineral development. This determination that A. holmgreniorum and A. ampullarioides are endangered species implements the Federal protections provided by the Act for these plants.
