Designation of Critical Habitat for Ivesia webberi: Proposed Rule

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the Ivesia webberi (Webber's ivesia) under the Endangered Species Act (Act). In total, approximately 2,011 acres (814 hectares) in Plumas, Lassen, and Sierra Counties in northeastern California and Washoe and Douglas Counties in northwestern Nevada fall within the boundaries of the proposed critical habitat designation. If we finalize this rule as proposed, it would extend the Act's protections to this species' critical habitat. The effect of this regulation is to designate critical habitat for Ivesia webberi under the Act.
