Filing Date Type File Action Taken Summary 01/30/2023 Complaint Download Complaint filed. Plaintiffs in Montana Federal Court Challenged Determination that Arctic Grayling Did Not Warrant Protection Under Endangered Species Act. A lawsuit filed in the federal district court for the District of Montana challenged the FWS’s determination that the upper Missouri River population of Arctic grayling did not warrant listing under the Endangered Species Act. The complaint alleged that the surviving populations “face a barrage of threats” such as low flows and barriers in river channels and warming water temperatures made “even more significant because of the current and predicted impacts of a changing climate, which are expected to reduce water flows and raise water temperatures even further.” The plaintiffs contended that the FWS impermissibly relied on unenforceable and voluntary conservation efforts to address threats to the grayling and also that the FWS failed to utilize best-available scientific information.
