MAGUIRE DAISY
The species name is listed as threatened under the Endangered Species Act since September 5, 1985.
Species Description: A member of the sunflower family, the Maguire daisy (Erigeron maguirei) is a perennial herb with a branched woody base. Its stems and spatulate-shaped leaves are densely spreading and hairy. Its flowers are dime sized with white or pink petals. Bits of sand commonly cling to the hairs of the leaves and stems.
Location: Maguire daisy has been located from 5,200 to 8,600 feet in elevation. Highest plant densities occur on mesa tops between 6,000 and 7,000 feet in elevation. The species occurs from the San Rafael Swell in Emery County, Utah, south into Wayne and Garfield Counties, Utah, through the Waterpocket Fold in Capitol Reef National Park. Maguire daisy occurs primarily on the Navajo Sandstone formation. Individuals have been located within steep, narrow, dry, rocky, and sandy canyon or wash bottoms of the Wingate, Chinle, and Navajo Sandstone formations; sandstone walls of the Wingate, Navajo, and Cutler formations; cracks of large boulders; sliderock; and atop mesas of the Navajo Sandstone. Populations within canyon bottoms apparently are small, incidental occurrences established from seeds dispersed by wind or overland flow from source populations on the mesa tops.
Recent Actions: On May 16, 2008, the Fish and Wildlife Service (Service) published a Federal Register Notice announcing the recovery of the Maguire daisy and proposed to delist the species. More detail is available in the attached documents:

The Maguire daisy was originally listed as endangered in 1985 (50 FR 36089). In 1996, the Service reclassified the species to threatened (61 FR 31054).
