Endangered and Threatened Wildlife and Plants; 5-Year Status Reviews of Little Colorado Spinedace, Sentry Milk-Vetch, Siler Pincushion Cactus, Slender Rush-Pea, and Yuma Clapper Rail in the Southwest Region

Samenvatting

We, the U.S. Fish and Wildlife Service, are initiating 5-year status reviews under the Endangered Species Act of 1973, as amended (Act), of the threatened Little Colorado spinedace (Lepidomeda vittata), endangered sentry milk-vetch (Astragalus cremnophylax var. cremnophylax), threatened Siler pincushion cactus (Pediocactus (=Echinocactus,=Utahia) sileri), endangered slender rush-pea (Hoffmannseggia tenella), and the endangered Yuma clapper rail (Rallus longirostris yumanensis). A 5-year review is based on the best scientific and commercial data available at the time of the review; therefore, we are requesting submission of any such information that has become available since our original listing of these five species or since the last 5-year review.
