Montana Grizzly Habitat Faces Renewed Road Lawsuit

Conservation groups say revised federal review still miscounts reclaimed roads, a dispute that has run since 2018 management plan changes.

Do you trust federal agencies to follow environmental laws when managing public lands?

Friends of the Wild Swan and the Swan View Coalition have threatened to sue the U.S. Forest Service and U.S. Fish and Wildlife Service over logging roads in the Flathead National Forest. The threat follows a newly revised biological opinion the federal agencies published in September 2026. The dispute is a legal action, not a shipped technology, and no outcome has been decided.

Why it matters

The groups allege that the Forest Service treats reclaimed, impassable roads the same as open roads when calculating total road density and motorized use. Their notice alleges that the second round of court-mandated revisions repeats earlier errors, extending a dispute that has run for years in Northwest Montana.

The dispute rests on a 2018 revision to the Flathead National Forest's management plan, which allows unused roads to be blocked along 50-300 feet of their length. The groups say the agencies' September 2026 revised biological opinion still counts those reclaimed roads as if they were open.

The players

Friends of the Wild Swan

A Montana conservation group that has litigated against federal forest management in the Flathead region.

Swan View Coalition

A Montana conservation coalition that works on forest and wildlife protection in the Swan Valley area.

U.S. Forest Service

The federal agency that manages the Flathead National Forest, including its road and travel management plan.

U.S. Fish and Wildlife Service

The federal agency that issues biological opinions on threats to endangered species such as grizzly bears.

The details

Under the 2018 plan, the Forest Service can render an unused road impassable by impeding motorized travel along 50 to 300 feet of the route. The groups argue this treatment is counted the same as full road use in calculations of total road density, which affects habitat assessments for grizzly bears. A biological opinion is the formal review by the U.S. Fish and Wildlife Service of whether a federal action jeopardizes a listed species. The groups allege the agencies arbitrarily dismissed the effect of impassable roads on grizzly bear habitat and connectivity.

2018: Forest Service revised its forest-wide management plan on road rehabilitation.
2019: The groups first sued, alleging the rule change violated the Endangered Species Act.
2024: The groups filed another lawsuit over the revised biological opinion.
June 5, 2026: A lawsuit challenged approval of a 7,700-acre forestry project.
October 23, 2026: The groups filed their notice of intent to sue.

The Tech Race

Forest road-density accounting in grizzly habitat is a long-running regulatory question rather than a technology race, and this dispute sits within the ongoing Endangered Species Act litigation over Flathead National Forest management. The case is one of several legal tests of how federal agencies count and treat decommissioned roads.

Montana residents who use Flathead National Forest roads may see changes to access and travel if the court rules on the road treatment. The outcome will determine whether reclaimed roads are counted as open for planning purposes.

The takeaway

Watch whether the Forest Service and Fish and Wildlife Service respond within the 60-day window set by the groups' notice. Whether a federal court accepts the revised biological opinion will show if reclaimed roads can be excluded from grizzly habitat road-density calculations.
