Endangered and Threatened Wildlife and Plants; Proposed Designation of Critical Habitat for Chorizanthe robusta var. robusta (Robust Spineflower)

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat pursuant to the Endangered Species Act of 1973, as amended (Act), for Chorizanthe robusta var. robusta (robust spineflower). Approximately 660 hectares (1,635 acres) of land fall within the boundaries of the proposed critical habitat designation. Proposed critical habitat is located in Santa Cruz County, California. Critical habitat receives protection from destruction or adverse modification through required consultation under section 7 of the Act with regard to actions carried out, funded, or authorized by a Federal agency. Section 4 of the Act requires us to consider economic and other relevant impacts when specifying any particular area as critical habitat. We solicit data and comments from the public on all aspects of this proposal, including data on economic and other impacts of the designation and our approaches for handling any future habitat conservation plans. We may revise this proposal to incorporate or address new information received during the comment period.
