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

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat pursuant to the Endangered Species Act of 1973, as amended (Act), for Chorizanthe robusta var. robusta (robust spineflower). Approximately 190 hectares (469 acres) of land fall within the boundaries of the critical habitat designation. Critical habitat is located in Santa Cruz County, California. This critical habitat designation provides additional protection 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 solicited data and comments from the public on all aspects of the proposed rule, including data on economic and other impacts of the designation, and our approaches for handling any future habitat conservation plans.
