Endangered and Threatened Wildlife and Plants; Determination of Critical Habitat for Thlaspi californicum (Kneeland Prairie Penny-cress)

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat pursuant to the Endangered Species Act of 1973, as amended (Act), for Thlaspi californicum (Kneeland Prairie penny-cress). The critical habitat consists of one unit whose boundaries encompass a total area of approximately 30 hectares (74 acres) in Humboldt County, California. Section 7 of the Act requires Federal agencies to ensure that any actions they fund, authorize, or carry out do not result in the destruction or adverse modification of critical habitat. As required by section 4 of the Act, we considered economic and other relevant impacts prior to making a final decision on the size and configuration of the critical habitat unit.
