Endangered and Threatened Wildlife and Plants; 90-Day Findings for Four Species

Issuing agencies

Abstract

We, the U.S. Fish and Wildlife Service (Service), announce 90- day findings on two petitions to add species to and one petition to remove a species from the Lists of Endangered and Threatened Wildlife and Plants under the Endangered Species Act of 1973, as amended (Act). We also announce a 90-day finding on one petition to revise critical habitat for a listed species. Based on our review, we find that the petitions to list the Fish Lake Valley tui chub (Siphateles bicolor ssp. 4) and delist the southern sea otter (Enhydra lutris nereis) present substantial scientific or commercial information indicating that the petitioned actions may be warranted. Therefore, with the publication of this document, we announce that we are initiating status reviews of these species to determine whether the petitioned actions are warranted. To ensure that the status reviews are comprehensive, we request scientific and commercial data and other information regarding the species and factors that may affect their status. Based on the status reviews, we will issue 12-month petition findings, which will address whether or not the petitioned actions are warranted, in accordance with the Act. We further find that the petitions to list the Pryor Mountain mustang population (Equus caballus) and to revise the critical habitat designation for Sonora chub (Gila ditaenia) do not present substantial information indicating the petitioned actions may be warranted. Therefore, we are not initiating status review of the Pryor Mountain mustang population or proceeding with a revision of critical habitat for the Sonora chub.
