MEMORANDUM

Friends of the Wild Swan, Alliance for the Wild Rockies, Montana Ecosystems Defense Council, and Native Ecosystems Council (collectively, “Plaintiffs”) appeal the district court’s summary judgment in favor of the United States Forest Service, United States Fish & Wildlife Service, and three individuals (collectively, the “Government Defendants”) in this suit challenging the decision authorizing the Colt Summit Restoration and Fuels Reduction Project (“the Project”). We have jurisdiction under 28 U.S.C. § 1291 , and affirm in part, vacate in part, and remand.

1. The “identification of the geographic area” that will be impacted by the Project “is a task assigned to the special competency of the appropriate agencies.” Kleppe v. Sierra Club, 427 U.S. 390, 414 , 96 S.Ct. 2718 , 49 L.Ed.2d 576 (1976); see also Idaho Sporting Cong., Inc, v. Rittenhouse, 305 F.3d 957 , 973 (9th Cir.2002) (“Ordinarily, an agency has the discretion to determine the physical scope used for measuring environmental impacts.”). The Forest Service appropriately justified its decision to look only at the Clearwater Lynx Analysis Unit in measuring the Project’s impact on the lynx and its critical habitat, noting, for example, that the Unit “would comprise more than 1 female hom-erange” and that the Project in total would impact “less than 10% of the Clearwater LAU.”

2. Plaintiffs contend that formal consultation under 50 C.F.R. § 402.14 be tween the Forest Service and the Fish and Wildlife Service was required because the Government Defendants failed to apply definitions in the Fish & Wildlife Service’s Consultation Handbook and incorrectly found the Project “not likely to adversely affect” the Canada lynx. But, Plaintiffs did not preserve this issue for appeal; they failed to raise it either in opposition to the Government Defendants’ motion for summary judgment or in response to the Government Defendants’ motions to dissolve the injunction. Thus, the issue is waived. See, e.g., Broad v. Sealaska Corp., 85 F.3d 422, 430 (9th Cir.1996) (declining to reach the merits of an issue that was not raised in the district court).

3. The Forest Service relied at least in part on “the standards in the 2007 Northern Rockies Lynx Management Direction” (the “Lynx Amendments”) in analyzing the Project’s effects. In Cottonwood Environmental Law Center v. United States Forest Service, issued after the decision below, we held that, because of procedural flaws, “the Forest Service must reinitiate consultation on the Lynx Amendments.” 789 F.3d 1075, 1085 (9th Cir.2015). We therefore vacate the district court’s determination that the Forest Service complied with the Endangered Species Act, 16 U.S.C. § 1531 et seq., in relation to the lynx and lynx critical habitat. On remand, the district court should consider in the first instance the Government Defendants’ argument that the Forest Service performed sufficient independent analysis of the Project to render any reliance on the Lynx Amendments harmless.

4. Each party shall bear its own costs on appeal.

AFFIRMED IN PART, VACATED IN PART, and REMANDED.
