On September 18, 2015, the U.S. Fish and Wildlife Service (Service) issued 90-day findings on 25 petitions to list various plants and animals under the Endangered Species Act (ESA). Of the 25 petitions, the Service concluded that 23 petitions presented substantial scientific or commercial information indicating that the petitioned actions may be warranted, and initiated 12-month status reviews for those species to determine if the listing is warranted under the ESA. These species include:
| Species | Latin Name | Range |

| Virgin River spinedace | Lepidomeda mollispinis mollispinis | Arizona, Nevada, and Utah |
| Yuman desert fringe-toed lizard | Uma rufopunctata | Arizona (United States) and Sonora (Mexico) |
The Service also concluded that a listing petitions for the Cahaba pebblesnail (Clappia cahabensis), found in Alabama, and a delisting petition for Stephens’ kangaroo rat (Dipodomys stephensi), found in California, did not present substantial scientific or commercial information indicating that the petitioned actions may be warranted. Accordingly, the Service declined to initiate status reviews for those species.
The Service has indicated that it will be accepting comments on the 23 species undergoing status reviews until November 17, 2015.
