Siuslaw NF / Oregon Dunes

**Siuslaw NF / Oregon Dunes – A-Tier (Moisture-Marginal Window)** You're looking at a classic late-summer dry spell that's keeping this region Tier A on potential rather than current abundance. Soil moisture is right at the edge—0.13 VWC is *technically* viable for fruiting, but it's been flatlined for two weeks with almost no rain. The king bolete, lobster, and cauliflower populations are your best bets if conditions hold or improve slightly; oysters and the drier-preference species (Yellow-Gilled Gym, Banded Mottlegill) can fruit in marginal conditions but will be scattered and small. The real story is that one decent rain—even 0.3–0.5"—would flip this from "hunt the edges" to genuinely productive. Until then, target riparian zones, north-facing slopes, and coastal fog drip areas where microclimate moisture lingers. Soil temps at 61°F are perfect; you're not moisture-limited by heat, only by the actual water deficit. **Hot tip:** Scout the dune slack complexes and interdune wetland margins now—they'll be your first indicators of activity, and they're often 2–3 days ahead of upland fruiting when moisture finally arrives.
