Initiation of 5-Year Status Reviews of 50 Species in California, Nevada, and the Klamath Basin of Oregon

We, the U.S. Fish and Wildlife Service (Service), are initiating 5-year status reviews of 50 species in California, Nevada, and the Klamath Basin of Oregon under the Endangered Species Act of 1973, as amended (Act). 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 new information on these species that has become available since the last review.
