RENO, Nev. — Webber’s ivesia (Ivesia webberi) was given protection under the Endangered Species Act
(ESA) as a threatened species on June 2, 2014 by the U.S. Fish and Wildlife Service (Service) in addition, the Service designated 2,170 acres of critical habitat for the species. "Webber's ivesia is threatened with extinction because of many factors, particularly the invasion of nonnative plant species and associated increases in the frequency and severity of wildfires throughout the species' limited range," said Ted Koch, State Supervisor for the Nevada Fish and Wildlife Office. Webber’s ivesia is restricted to sites with sparse vegetation and shallow, rocky, clay soils on mid-elevation flats, benches or terraces between 4,475 and 6,237 feet elevation in Washoe and Douglas Counties in Nevada, and in Lassen, Plumas and Sierra Counties, in California. All 17 known populations of Webber’s ivesia are within the transition zone between the eastern edge of the northern Sierra Nevada and the northwestern edge of the Great Basin. One of these populations is presumed extirpated (no longer found). Webber’s ivesia is a member of the rose family. It is a low-growing, perennial forb that is approximately ten inches in diameter with clusters of leaves that lie nearly flat on the ground. It has greenish-gray leaves, dark red, wiry stems, and head-like clusters of small bright yellow flowers. Flowering typically begins in May and extends through June and the whole plant becomes reddish-tinged late in the season.
