Five environmental groups filed a lawsuit in the federal district court for the District of Colorado challenging the decision of the U.S. Department of the Interior and the U.S. Fish and Wildlife Service (FWS) to remove the Preble’s meadow jumping mouse. The complaint called the mouse an "indicator of the health of its ecosystem" and alleged that it faced threats from the impacts of global climate change. The plaintiffs asserted that the delisting relied on a definition of the term "significant portion of its range" in the definitions of "endangered" and "threatened" that was at odds with statutory language. The plaintiffs also said the delisting was not based on the best scientific data available or a reasonable analysis of the Endangered Species Act's five statutory listing factors.
