Center for Biological Diversity v. U.S. Fish & Wildlife Service
Summary: Center for Biological Diversity ("CBD") filed an action for declaratory and injunctive relief under the Endangered Species Act, seeking protection for the Pacific fisher (a medium-sized brown mammal in the weasel family found only in North America). All parties moved for summary judgment. The CBD was the party that submitted the original petition to list this distinct population segment as endangered in 2000 (after various petitions were filed since 1990 with no action). In 2014, the U.S. Fish & Wildlife Service (the "Service") publicly proposed to list the Pacific fisher as threatened and sought public comment. In April 2016, the Service withdrew the proposed listing, finding that: populations will persist in the future; wildfires will have beneficial consequences; there "may be" breeding and interchange with other populations; and there were only a small number of confirmed deaths due to toxicosis from anticoagulant rodenticides. Plaintiffs now challenge that listing reversal as arbitrary and capricious, and seek an order requiring the Service to publish a new rule within 90 days based on “the best scientific and commercial data available." This court first examined the effect of anticoagulant rodenticides on the Pacific fisher. The court found the Service's assessment of the increase of the emerging threat from toxicosis was arbitrary and capricious, and that the Service "cherry picked" the Gabriel study to say that the study was uncertain. As to population trends, the court found that the Service based its conclusion on limited and inconclusive trend data and ignored the studies' conclusions. In fact, the court stated, "[h]ere, the absence of conclusive evidence of Pacific fisher persistence does not stand alone. The Service does not dispute that the Pacific fisher population has declined dramatically." In the end, the court granted plaintiff CBD motion for summary judgment and denied defendant Service's motion. The court directed the Service to prepare a new rule by March 22, 2019 (which denied plaintiff's motion for a 90-day rule and also denied the Service's request to "brief the timeline in order to evaluate staffing and budget constraints").
