Black River State Forest and the surrounding north-central WI sand country — bridge between the Driftless Area to the south and the Northwoods to the north. Pine barrens (jack pine, oak savanna), oak-hickory ridges, and bottomland hardwoods (silver maple, swamp white oak) along the Black River. Spring morels in disturbed bottoms and dying elm; chanterelles in oak woodlands; matsutake-candidate Tricholoma magnivelare in jack pine; chicken-of-the-woods on red and white oak.

**Black River SF / Driftless — S-Tier Heat & Moisture Sweet Spot** You're sitting in a rare convergence: sustained soil temps at 73°F with 2+ weeks of consistent moisture and zero drought stress. This explains the 57-species viability list—essentially everything from early-summer flushers (Chicken of the Woods, parasols, wine caps) to opportunistic wood-decayers (turkey tail, artist's conk, jelly ears) is triggering simultaneously. The Driftless topography is holding moisture better than surrounding areas. The only brake is moderate desiccation risk—soil VWC at 0.21 is solid but not saturated, meaning flush window closes if you get 3+ days of heat without rain. No precip is forecasted here in the next 48 hours, so yields will peak *today and tomorrow*, then decline hard by mid-week. Watch for sudden boletus emergence (Aspen Bolete, Frost's Bolete, Two-Colored Bolete) in the next 12 hours; this cohort is a final indicator of peak conditions before the drying phase kicks in. **Hot tip:** Hit north-facing oak and aspen stands in early morning before 9 AM—that's where residual dew and shade keep soil moisture longest, and boletes will flush earliest there.

Primordia readiness: Cold = mycelium dormant. Activating = soil warming, primordia building. Primed = 5+ sustained warm days at species threshold; fruiting imminent if moisture cooperates. Based on Schmidt 1983 / Mihail 2007.
