Background

  • The U.S. Forest Service prepared an Environmental Assessment (EA), Biological Assessment (BA), and a Decision Notice/Finding of No Significant Impact (DN/FONSI) for the Tennessee Creek Project (2014) — a 10–15 year forest-management plan (clearcutting, thinning, prescribed burns) across ~16,450 acres to address beetle infestation, fire risk, and habitat/watershed goals.
  • About 9,480 acres in the project area are mapped as Canada lynx habitat within two Lynx Analysis Units (LAUs); the Service assumed a conservative worst-case that all mapped lynx habitat might be treated.
  • The Service relied on prior lynx-focused planning (LCAS, Lynx Conservation Agreement, and the Southern Rockies Lynx Amendment or SRLA) and incorporated project constraints and conservation measures (e.g., avoid healthy spruce-fir and stands with >35% dense horizontal cover; limits on clearcut/regeneration rates; track treated acreage) to limit impacts to lynx and snowshoe-hare winter habitat.
  • The EA concluded the Project "may affect, but is not likely to adversely affect" lynx and that SRLA standards would not be violated even in the worst-case scenario; U.S. Fish and Wildlife Service concurred; Service issued a FONSI and proceeded without preparing an EIS.
  • WildEarth Guardians sued under the Administrative Procedure Act, claiming the EA failed to take a hard look at lynx impacts and that the Service should have prepared an Environmental Impact Statement (EIS). The district court upheld the agency; the Tenth Circuit affirmed.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether EA inadequately assessed effects on lynx (failure to take a “hard look”) EA omitted site-specific locations, baseline quantification of denning/winter habitat, and other data necessary to assess impacts EA reasonably used existing lynx science (LCAS/SRLA), employed a conservative worst-case analysis, and included conservation measures; site-specific locations impracticable over 10–15 years Court held EA adequate; Service took a reasoned, rational “hard look” and did not act arbitrarily or capriciously
Whether lack of site-specific treatment locations required an EIS Richardson requires site-specific analysis; without locations impact on fragmentation unknown Richardson distinguishable — here EA analyzed worst-case across mapped habitat and limited treatments by standards/guidelines; flexibility justified by adaptive, multi-year project management Court held no per se rule requiring site-specific locations; Service’s worst-case and constraint-based analysis was reasonable
Whether EA needed baseline data / ground-truthing to ensure compliance with protections Must collect baseline data now to evaluate/monitor impacts and ensure SRLA limits are met Service had sufficient data and relied on expert, precedent studies; courts presume agencies will follow law; further baseline not required to make decision Court rejected need for additional baseline data now; agency had adequate information to support conclusion
Whether FONSI (no EIS) was permissible given potential effects on lynx and cumulative impacts Project size, potential long-term loss of denning habitat, and effects on linkage areas create significant, controversial, or uncertain impacts — thus an EIS required Size alone not dispositive; Service evaluated context/intensity factors in 40 C.F.R. §1508.27 and reasonably found effects not significant; SRLA compliance, mitigation, and worst-case analysis reduce uncertainty Court held FONSI was not arbitrary or capricious and an EIS was not required — no clear error in significance determination
