Defenders of Wildlife v. United States Forest Service, No. 23-1093 (10th Cir. 2024)
Annotate this Case
The case revolves around a dispute over the management plan for the Rio Grande National Forest (RGNF) in Colorado, particularly its impact on the Canada lynx, a species listed as threatened. The United States Forest Service (USFS), tasked with managing the RGNF, revised its Land Management Plan in response to a significant spruce beetle epidemic. The revised plan was assessed by the United States Fish and Wildlife Service (FWS), as required by the Endangered Species Act (ESA), to consider the plan's effects on the Canada lynx. FWS issued a Biological Opinion in 2021 concluding that the plan would not likely jeopardize the lynx's continued existence. The Defenders of Wildlife contested this conclusion, arguing that the Biological Opinion violated the ESA and the Administrative Procedure Act (APA), and that USFS improperly relied on the opinion in preparing the plan.
The United States Court of Appeals for the Tenth Circuit affirmed the lower court's dismissal of the Defenders’ petition. The Court held that FWS did not violate the ESA or the APA in its assessment, and that USFS appropriately relied on FWS's conclusions. The Court noted that the FWS had reasonably considered all relevant data, including information about the Canada lynx subpopulation in Colorado, and had made a reasoned decision based on this data. The Court also found that the FWS adequately addressed the potential impact of the plan on both low-use and high-use lynx habitats. The Court concluded that because the FWS's actions were not arbitrary, capricious, or contrary to law, the USFS did not act arbitrarily in relying on the Biological Opinion.
