Endangered and Threatened Wildlife and Plants; Revised Endangered Status, Revised Critical Habitat Designation, and Taxonomic Revision for Monardella linoides ssp. viminea

Type: report

Article abstract: We, the U.S. Fish and Wildlife Service (Service), recognize the recent change to the taxonomy of the currently endangered plant taxon, Monardella linoides ssp. viminea, in which the subspecies was split into two distinct full species, Monardella viminea (willowy monardella) and Monardella stoneana (Jennifer’s monardella). Because the original subspecies, Monardella linoides ssp. viminea, was listed as endangered under the Endangered Species Act of 1973, as amended (Act), we reviewed and updated the threats analysis that we completed for the taxon in 1998, when it was listed as a subspecies. We also reviewed the status of the new species, Monardella stoneana. We retain the listing status of Monardella viminea as endangered, and we remove protections afforded by the Act from those individuals now recognized as the separate species, Monardella stoneana, because the new species does not meet the definition of endangered or threatened under the Act. We also revise designated critical habitat for Monardella viminea. In total, approximately 122 acres (50 hectares) in San Diego County, California, fall within the boundaries of the critical habitat designation. We are not designating critical habitat for Monardella stoneana because this species does not warrant listing under the Act.
