Endangered and Threatened Wildlife and Plants; Endangered Status for Four Plants From Vernal Pools and Mesic Areas in Northern California

The Fish and Wildlife Service (Service) determines endangered status pursuant to the Endangered Species Act of 1973, as amended (Act), for four plants--Lasthenia conjugens (Contra Costa goldfields), Navarretia leucocephala ssp. pauciflora (few-flowered navarretia), Navarretia leucocephala ssp. plieantha (many-flowered navarretia), and Parvisedum leiocarpum (Lake County stonecrop). These species grow in and around the margins of vernal pools and in seasonally wet areas in northern California. Habitat loss and degradation imperil the continued existence of these plants. This final rule implements protection provisions of the Act for listed plants.
