Buffalo NR corridor — first National River, deep limestone bluffs and old-growth pockets in the Ozark Plateau. Mixed mesophytic forest in coves: tulip poplar, sugar maple, white oak, basswood. Excellent spring morel hunting in dying-elm flats and tulip poplar coves.

# Buffalo National River – S-Tier | May 29, 2026 This is a textbook spring sweet spot: 70°F soil, sustained moisture above thresholds for a full week, and zero drought stress. You've got 31 species firing simultaneously across saprophytes, lignicolous polypores, and cup fungi—the rare "hit everything" window. The moderate desiccation risk is real but not binding; the 0.35 VWC today and consistent 7-day average of 0.25 mean conditions are still favorable for another 48–72 hours before the drying curve accelerates. Target the fast flushers first (Oysters, Wine Caps, Dryad's Saddle, Fairy Rings) while they're still in optimal moisture phase. The polypores and woody fungi are patient—they'll fruit regardless, but this is prime window for the ephemeral stuff. Watch the forecast: any dip below 0.20 VWC mid-week will collapse the upper-tier species rapidly. Hot tip: Scout north-facing ravines and seeps where residual moisture pools—they'll extend your viable window by 3–4 days even as upland sites begin to fade.

⚠ 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.

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.
