Endangered and Threatened Wildlife and Plants; Determination of Threatened Status for Four Plants From the Foothills of the Sierra Nevada Mountains in California

The U.S. Fish and Wildlife Service determines threatened status for Brodiaea pallida (Chinese Camp brodiaea), Calyptridium puchellum (Mariposa pussypaws), Clarkia springvillensis (Springville clarkia), and Verbena californica (California vervain) pursuant to the Endangered Species Act of 1973, as amended (Act). These four plants are known from serpentine, clay, or granitic soils in the southwestern foothills of the Sierra Nevada Mountains in central California. These plants are variously threatened by one or more of the following: urbanization, roadway maintenance activities, off-highway vehicle use, recreational placer gold mining, heavy livestock grazing and/or trampling, and inadequate regulatory mechanisms. These species are also vulnerable to extirpations from random events due to small number and size of populations, and/or small range of the species. A notice of withdrawal of the proposal to list Allium tuolumnense (Rawhide Hill onion), Carpenteria californica (carpenteria), Fritillaria striata (Greenhorn adobe lily), Lupinus citrinus var. deflexus (Mariposa lupine), Mimulus shevockii (Kelso Creek monkeyflower) and Navarretia setiloba (Piute Mountain navarretia) is being published concurrently with this final rule.
