Montana Field Guide

DRAFT: Requesting feedback on the 2026 revised rank, factors, and State Rank Reason outlined below and in the Conservation Status Rank Report. Gaultheria humifusa is widespread across mountainous areas of western and central Montana, where it is common in some subalpine and alpine habitats. Occurrences are almost entirely on publicly managed lands, including many on National Forest lands managed for multiple use. Many other populations are within designated wilderness areas or within Glacier National Park. Population levels are uncertain though they are robust. Trends are unknown though populations have likely been relatively stable in the recent past or experienced only minor declines. Climate change may negatively affect this species over the next several decades. However, the timing and magnitude of potential impacts are largely unknown. Although climate change is listed as a potential threat to the species, it does not affect the overall threat rank or scoring, or the final subnational rank.
