90-Day Finding on a Petition To Delist the Sacramento Mountains Thistle (Cirsium vinaceum) and Initiation of 5-Year Status Review

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to remove the threatened Sacramento Mountains thistle (Cirsium vinaceum) (thistle) from the Federal List of Threatened and Endangered Plants, under the Endangered Species Act of 1973, as amended (Act). We find the petition does not present substantial information indicating that delisting of the thistle may be warranted. Therefore, we will not initiate a further 12-month status review in response to this petition under section 4(b)(3)(B) of the Act. However, we are initiating a 5-year review of this species under section 4(c)(2)(A) of the Act to consider information that has become available since we listed the species as threatened on June 16, 1987 (52 FR 22933). This will provide the public an opportunity to submit new information on the status of the species. We invite all interested parties to submit comments or information regarding this species.
