Another native Utah plant, a perennial herb with orange flowers clinging to survival in Washington County, has been listed as an endangered species.
The U.S. Fish and Wildlife Service determined Gierisch mallow, or Sphaeralcea gierischii, faces enough threats from gypsum mining and motorized recreation to warrant protection under the federal Endangered Species Act, according to a rule posted Tuesday on the Federal Register.
This rare mallow is found only on gypsum outcrops associated with the upper limestone layer of the Kaibab Formation in Washington County and the adjacent Mohave County in Arizona. Gierisch mallow was named a distinct species of Sphaeralcea in 2002 when scientists distinguished it from Rusby's globemallow because of its larger flowers and smooth leaves.
