Friends of the Wild Swan and Swan View Coalition filed a notice of intent to sue the U.S. Forest Service and U.S. Fish and Wildlife Service dated October 23, 2026. The groups say a newly revised biological opinion published in September 2026 replicates errors from the prior round of court-mandated revisions.
Why it matters
The dispute concerns how unused logging roads in the Flathead National Forest are closed and counted in road-density calculations, which the groups argue affects grizzly bear habitat and connectivity in Montana. Ongoing litigation over the Flathead forest plan could shape how Montana's federal forestlands are managed.
The groups' notice cites a 2018 Flathead National Forest plan revision that allows roads to be rendered impassable along 50-300 feet of the route while still counting them as reclaimed. The agencies have not publicly addressed the groups' specific allegations, and whether the revised biological opinion will be upheld remains unresolved.
The players
Friends of the Wild Swan
A Montana conservation group that has long litigated federal forest management decisions in the Flathead region.
U.S. Forest Service
The federal agency that manages the Flathead National Forest and its road and forest-wide management plans.
U.S. Fish and Wildlife Service
The federal agency responsible for issuing the biological opinion assessing threats to endangered species such as grizzly bears.
The details
The groups allege that the Forest Service's 2018 revision lets unused roads be closed without full rehabilitation, including exempting officials from a requirement to fully rehabilitate roadside culverts. They say the agencies arbitrarily dismissed how impassable roads affect grizzly bear habitat, and they will file suit in federal court if the government does not act within 60 days.
Timeline
2018: Forest Service revised the forest-wide management plan on road rehabilitation.
2019: Groups first sued, alleging the rule change violated the Endangered Species Act.
2024: Groups filed another lawsuit over the revised biological opinion.
June 5, 2026: Lawsuit filed challenging approval of a 7,700-acre forestry project west of Hungry Horse Reservoir.
October 23, 2026: Groups filed their notice of intent to sue.
Big Picture
This dispute extends litigation that began when the Flathead National Forest's 2018 forest-wide plan revision was challenged under the Endangered Species Act in 2019. The groups' new notice follows the same pattern of repeated lawsuits over revised federal documents that have not satisfied court-mandated requirements.
Montana residents who use Flathead National Forest roads for recreation or hunting could see some routes closed or made impassable depending on how the revised rules are applied. The dispute affects how much road access remains on federal lands in Northwest Montana.
The takeaway
Residents who rely on Flathead National Forest roads should watch whether the 60-day response window produces changes to road-closure rules. The outcome may shape how grizzly bear habitat is protected across Northwest Montana.
What happens next
The federal agencies have 60 days from the October 23, 2026 notice to respond before the groups file suit in federal court.
