Rule of Law:
An agency's decision regarding scientific methodology, such as how to measure and maintain biological diversity under the National Forest Management Act (NFMA) and National Environmental Policy Act (NEPA), is entitled to deference and will be upheld unless it is arbitrary, capricious, or an abuse of discretion. An agency is not required to adopt a specific scientific theory, like conservation biology, so long as its chosen methodology is rational and it gives a reasoned explanation for rejecting alternatives.
Facts:
- The U.S. Forest Service (Service) was required by federal law to develop long-term land and resource management plans for the Nicolet and Chequamegon National Forests in Wisconsin.
- The plans were intended to guide forest management activities, including timber harvesting, road construction, and wildlife habitat creation, for ten to fifteen years.
- During the public comment period, Sierra Club submitted extensive materials advocating for the application of 'conservation biology,' a scientific discipline emphasizing the need for large, unfragmented habitats to maintain biodiversity.
- Sierra Club proposed that the Service create large 'Diversity Maintenance Areas' (DMAs) where logging and road building would be restricted to prevent forest fragmentation.
- In developing its final plans, the Service used its own methodology to address biodiversity, which focused on analyzing vegetative diversity and monitoring 'management indicator species' (MIS).
- The Service considered the principles of conservation biology and the DMA proposal but declined to adopt them in the final plans.
- The Service concluded that the application of conservation biology to the forests in the Lake States region was uncertain and that further research was needed before making it a priority.
- The final approved plans authorized timber harvesting and other activities that Sierra Club alleged would lead to the fragmentation of the forests.
Procedural Posture:
- Sierra Club challenged the Nicolet and Chequamegon forest management plans in administrative appeals to the Chief of the U.S. Forest Service.
- The Chief of the Forest Service affirmed the plans in part and remanded them in part for specific alterations.
- Sierra Club filed two lawsuits against the U.S. Forest Service in the U.S. District Court for the Eastern District of Wisconsin, challenging the final plans.
- In the district court, both parties filed cross-motions for summary judgment.
- The district court first held that Sierra Club's claims were justiciable (i.e., had standing and were ripe).
- The district court then granted summary judgment in favor of the U.S. Forest Service on the merits in both cases.
- Sierra Club, as appellant, appealed the district court's grants of summary judgment to the U.S. Court of Appeals for the Seventh Circuit, where the cases were consolidated.

Issue:
Does the U.S. Forest Service act arbitrarily and capriciously in violation of the National Forest Management Act and the National Environmental Policy Act by developing forest management plans that do not apply the principles of conservation biology, when the agency considered but ultimately rejected that scientific methodology as uncertain in its application?
Opinions:
Majority - Flaum, Circuit Judge.
No. The U.S. Forest Service did not act arbitrarily and capriciously because federal environmental statutes do not mandate the use of any particular scientific methodology to satisfy the requirement to provide for biological diversity. Under the deferential 'arbitrary and capricious' standard of review, an agency's choice of methodology will be upheld so long as it is rational and the agency considers relevant factors. The National Forest Management Act (NFMA) and its regulations require the Service to 'provide for diversity' but do not prescribe a specific method for doing so. Similarly, the National Environmental Policy Act (NEPA) requires agencies to take a 'hard look' at environmental consequences but does not mandate particular substantive outcomes. Here, the Service considered the principles of conservation biology presented by the Sierra Club but reasonably concluded that the science was uncertain in its application to the specific forests at issue. The Service's own methodology, which focused on vegetative diversity and the use of management indicator species, was a rational approach to fulfilling its statutory obligations. The Service's decision to reject a scientific theory it deemed uncertain does not constitute a failure to take a 'hard look' or a violation of its duty to use 'high quality' science.
Analysis:
This decision reinforces the high degree of judicial deference afforded to federal agencies' scientific and technical judgments under the 'arbitrary and capricious' standard of review. It establishes that while environmental statutes like the NFMA and NEPA impose clear procedural and substantive duties, they leave the specific scientific methodology for fulfilling those duties to the agency's discretion. The ruling clarifies that an agency can satisfy its NEPA 'hard look' obligation by considering a novel scientific theory and providing a rational basis for declining to apply it, such as uncertainty. This precedent makes it more difficult for plaintiffs to challenge agency actions based on disagreements over competing scientific theories, solidifying the agency's role as the primary expert decision-maker.
