Great Dismal Swamp National Wildlife Refuge — 112,000 acres straddling the VA-NC line. Atlantic white cedar, bald cypress, tupelo, red maple, and loblolly pine over peat soils. Lake Drummond at the center. Unique "pocosin" wetland ecology with Atlantic white cedar stands — a southern-appalachian species reaching its eastern limit here. Oyster mushroom year-round on dying cedars and tupelo; chicken-of-the-woods on water oak; summer chanterelles on drier hummocks.

Great Dismal Swamp NWR is rated Excellent. Soil is sitting at about 70°F, and the swamp's saturated peat is holding moisture (0.18 VWC today, 0.20 over the 7-day average) even though recent rain has been light, with 0.53" over the past week. There's no drought and no limiting factor, and the moisture trigger is met. Every modeled species is viable at high confidence, including oyster, chanterelle, chicken of the woods, hen of the woods, lion's mane, honey mushroom, and indigo milk cap, plus the yellow-gilled gym and the stinkhorn trio (Ravenel's, elegant, lantern). Temperatures have held above threshold for 6-7 of the last 7 days across the board. The one thing to watch is the thin rain input: if the next week stays dry, VWC will start drifting down and the flush will taper, especially on the mycorrhizal species like chanterelle and indigo milk cap, which depend on consistent moisture. A cool front or a good soaking rain would extend the run. Hot tip: Hit the hardwood-dominated ridges and tree bases for hen of the woods and chicken of the woods first, since those are the ones that fade fastest if the moisture slips, and save the lower, wetter ground for oysters and lion's mane on downed wood.

⚠ 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.
