Endangered and Threatened Wildlife and Plants; Endangered Status for Three Plants and Threatened Status for One Plant From Sandy and Sedimentary Soils of Central Coastal California

摘要

The U.S. Fish and Wildlife Service (Service) determines endangered status pursuant to the Endangered Species Act of 1973, as amended (Act), for three plants: Chorizanthe pungens var. hartwegiana (Ben Lomond spineflower (also previously known as Hartweg's spineflower)), Chorizanthe robusta (inclusive of var. hartwegii and var. robusta) (robust spineflower), and Erysimum teretifolium (Ben Lomond wallflower). The Service also determines threatened status for one plant: Chorizanthe pungens var. pungens (Monterey spineflower). These four taxa occur in coastal habitats of southern Santa Cruz and northern Monterey Counties and are imperiled by one or more of the following factors: Habitat destruction due to residential and golf course development, agricultural land conversion, sand mining, military activities, and encroachment by alien plant species. This rule implements the protection and recovery provisions afforded by the Act for these plants.
