**Helena/Big Belts – Tier A Analysis** You're sitting in a paradox: the biodiversity is exceptional (37 species viable), but soil VWC of 0.13 is barely holding the line. The A-tier reflects the *breadth* of what can fruit here under normal conditions, not current intensity. Moisture is your only constraint—two weeks of modest precipitation (0.59") haven't recharged the duff layer enough to trigger the moisture threshold, leaving everything in a "ready but waiting" state at 64°F soil temp. Focus on saprophytes and wood-decayers first: Chaga, Birch Polypore, Jelly Antler, and Angel Wings don't depend on fresh soil moisture the way Hedgehogs and Milk Caps do. If you're targeting ground-fruiting species, prioritize lower elevations (4,000–5,500 ft) where thermal mass and aspect shelter maintain slightly higher moisture. Watch the forecast obsessively—even 0.3" of rain in the next 48 hours will flip multiple species from "marginal" to "flush," especially fast-responders like Cauliflower, Lobster, and Saffron Milk Caps. Desiccation risk is moderate, meaning established mycelium is fine, but pinning is suppressed. Hot tip: Scout north-facing slopes and seepage zones now before the rain; mark the sweet spots so you can hit them hard the moment precipitation arrives.

⚠ Road Access Notice

Always verify road access is public before following GPS directions to mountain areas. Many forest roads are seasonal, gated, or require 4WD. Dispersed camping follows USFS/BLM rules (typically 14-day limit). Check ranger district offices for current road and campground conditions.
