Lawsuits involving land management plans are uncommon, but we have two to look at right now. Both also involve the interplay between land management plans and the Endangered Species Act. A district court has decided that the Nantahala-Pisgah National Forest LMP violated the ESA’s requirements for consultation on listed species. At the other end of the court process, the BLM has been sued (again) for a plan that allegedly fails to adequately address the greater sage-grouse, a species for which listing was prevented by agency actions to amend BLM (and Forest Service) land management plans.
Court decision in Defenders of Wildlife v. U. S. Forest Service (W. D. North Carolina)
On March 31, the district court vacated the Fish and Wildlife Service’s Biological Opinion for the revised Nantahala-Pisgah Forest Plan, which violated the Endangered Species Act with respect to four bat species. This means the forest plan does not comply with the ESA and may not be implemented. The court said its decision “voids authority for the Revised Forest Plan,” and it appears this means reversion to the prior plan. The revised plan would have increased the amount of logging. The opinion can be downloaded from the article. There is (or was) a second lawsuit pending against the revised plan, discussed here.
The court did not agree with the plaintiffs on all counts. In particular, it upheld the use of the national forest boundaries as the ESA action area for the forest plan decision, despite some evidence of indirect effects occurring outside of this boundary. This affects the scope of required analysis. The court did find the following flaws in the FWS BiOp.
The environmental baseline was inadequate because, even though forest plans are programmatic decisions and may require a “broader scope,” “Other than the general and unexplained conclusions that bats use the Forests and that the Forests contain suitable habitat for the bats, the environmental baseline offers no assessment of the conditions of the bats that are specific to the action area.” The BiOp’s environmental baseline evaluation also failed to account for the actual impacts of any past or present federal, state, or private actions in the action area.
Again recognizing that this is a programmatic decision, the court stated with regard to cumulative effects that, “Even when FWS lacks comprehensive information, it may still determine whether ‘activities in particular areas [are] fundamentally incompatible with the continued existence of the species’ and, in light of that determination, recommend constraints on certain activities in particular areas as needed” (which in the case of a forest plan could be additional protective plan components). The BiOp also did not address the effects of the non-federal actions that had been identified in the record, and the court construed the overall lack of effort as “an improper wholesale deferral” of effects analysis to future projects.
The court also found the “no jeopardy” determination by the FWS in the BiOp to be arbitrary and capricious because it did not explain how they reached that determination in light of the conclusions in the biological assessment and other facts indicating that the species on the forest were at high risk and important to the species as a whole. While the court also faulted the Forest Service for relying on this improper jeopardy determination, it determined that the Forest Service BA adequately provided the best available science to the FWS, even if they may have misinterpreted that science.
New lawsuit: Montana Wildlife Federation v. Burgum (D. Montana)
On March 26, the Montana Wildlife Federation, The Wilderness Society and Defenders of Wildlife filed a lawsuit against the 2025 amendments to the Montana and Wyoming BLM resource management plans, which modified 2015 plan amendments that convinced the Fish and Wildlife Service to not list greater sage-grouse as threatened or endangered. The BLM’s 2025 amendments make a number of changes that reduce protection that had been provided to sage-grouse in the 2015 plans. A lawsuit by different parties was discussed here.
This case will focus on oil and gas and mineral development. According to the complaint, the BLM removed a requirement to prioritize development outside of important sage-grouse habitat, abandoned a provision of the prior plans calling for a mineral withdrawal that would have prevented mining on 10 million acres of the most important sage-grouse habitat, and weakened numerous minimization and mitigation measures.
The plaintiffs allege violations of FLPMA, NEPA and the APA. The FLPMA requirement is to manage for sustained yield of wildlife, and the Fish and Wildlife Service had previously said the conservation measures removed were necessary to prevent further decline and likely listing under the Endangered Species Act. Alleged violations of NEPA involve failure to acknowledge, based on the best available science, that these amendments would be less protective of sage-grouse and to disclose those adverse effects, and failure to properly evaluate the loss of mitigation measures that were already proving inadequate. The case also will address the effects of the One Big Beautiful Bill Act (which was adopted between the final EIS and the ROD for these amendments) on BLM’s discretion to not lease sage-grouse habitat for oil and gas, and the effects on sage-grouse of claimed likely additional development that would be allowed. The article includes a link to the complaint.
Court decision in Montana Wildlife Federation v. Haaland (9th Cir.)
(I apparently missed this decision at the time – which points out that my search system isn’t perfect, and if someone feels like I missed something important to federal lands management, they should let me know.)
On January 17, 2025, the Ninth Circuit Court of Appeals enjoined several leases in sage-grouse habitat conducted under the 2015 sage-grouse plan amendments in response to two separate lawsuits. The Montana Wildlife Federation case was heard in the Montana district court and the Western Watersheds Project case originated in Idaho (though these appeals to the Ninth Circuit did not involve leases in either state).
The circuit court determined that a BLM “instructional memo,” which interpreted the 2015 plan to require prioritization of oil and gas permits outside of sage-grouse habitat only when there was a backlog in processing expressions of interest, was plainly inconsistent with the 2015 plan (which had no such qualifier) because “IM 2018-026 prioritizes administrative efficiency over the 2015 Plan’s stated purpose of protecting sage-grouse habitat.” The court concluded, “The agency thus failed to draw a “rational connection” between the backlog requirement and the substantive, conservation-oriented goals of the 2015 Plan.” While the court did not invalidate the memo, it found that the June 2018 Wyoming lease sales (addressed by the Montana court), which applied the interpretation in the memo, violated FLPMA because they did not conform to the management plans. The court found this substantive violation of FLPMA warranted vacating the leases.
In the Idaho case, the 9th Circuit concluded that BLM violated both FLPMA and NEPA with respect to five lease sales (677 leases) when it eliminated in some instances and severely shortened in others the various public participation periods without providing an adequate explanation for its change in policy. The court stated, “BLM failed entirely to acknowledge the potential costs of reducing public participation in leasing decisions, including that shortening the participation opportunity might lead to insufficient consideration of the environmental impacts of its actions.” The court found this procedural violation to be less severe, and enjoined the relevant sales without vacating the leases in Nevada, Wyoming and Utah.
