DRAFT: Requesting feedback on the 2026 revised rank, factors, and State Rank Reason outlined below and in the Conservation Status Rank Report.
Stenanthium occidentale is a somewhat uncommon to locally common species in western Montana. No significant and widespread threats to the species are known, and population levels are robust enough that its viability in the state should not be a concern.
