Arson and debris drive 71% of KY ignitions. Rx-burn capacity runs 60–74% short of plan. Storm-corridor ignitions are the next loss vector.
Kentucky averages 1,400 wildland fires and 46,800 acres burned per year, concentrated 62% in the March–April window with a clear secondary peak in November. Cause attribution is unforgiving: 71% arson + debris. Meanwhile, the institutional response — prescribed fire, burn-day notification, smoke-window forecasting — is structurally underbuilt. KDF executes ~3,200 ac/yr against a ~12,000-ac plan; DBNF runs ~6,500 against a 25,000-ac target; NPS 1,800 against 4,500 — 60–74% short across the agency stack. The next loss vector is corridor: 14 of 42 major outage events since 2018 occurred in fuel-loaded corridors with documented downstream ignitions.

L1 · WILDFIRE LOAD
KDF reports Kentucky wildfire load swung from 17,875 ac (2022) to 47,662 (2023) to 23,896 (2024) across 937 fires (KDF, 2025). The 2016 anomaly remains the high-water mark at 141,180 ac; SE coalfield counties — Bell, Harlan, Letcher, Pike — carry the disproportionate share.

L2 · CAUSE ATTRIBUTION
Cause coding in KDF's annual reports puts arson and debris-burning together at 71% — a structural finding, not a year-anomaly. The remaining 29% spreads across equipment, lightning (rare for the region), railroad, smoking, and miscellaneous.

Arson clusters geographically; debris-burning correlates with peak-window low-RH days. Both yield to outreach and burn-day permits — but only with field staffing.
L4 · Rx-BURN CAPACITY
The institutional answer to a fire-adapted landscape is prescribed fire, and across the agency stack KY runs 60–74% short of plan.
- KDF — ~3,200 ac/yr realized · ~12,000 planned · 73% short
- DBNF (USFS) — ~6,500 ac/yr · target 25,000 · 74% short
- NPS (Mammoth, Cumberland Gap) — ~1,800 ac/yr · target 4,500 · 60% short
- Burn-day calendar — 38 favorable days median, only 19 used (50%)
- Constraints — staffing 2:1 below NWCG min; permit lag 11 d; KY-DAQ smoke window narrow.
"Arson + debris is 71% of cause. The fix isn't a new sensor — it's a burn calendar, a permit window, and 14 more burn bosses. The tools we have are 50% used."

L3 · SMOKE EXPOSURE
EPA AQS & KDF smoke-day records show seasonal PM2.5 spikes concentrated downstream (NE-prevailing winds) of SE coalfield ignition cells. Smoke-day count averages 9 per fall, 12 per spring across the affected airshed.
Title VI cohort overlap: 37 census tracts intersect a high-smoke-day envelope, meaning notification + advisory pipelines are not optional for environmental-justice compliance.
L5 · STORM/OUTAGE → CORRIDOR FIRE
Storm-driven utility outages are the next loss vector. Of 42 major events (≥50,000 customers) since 2018, 14 occurred in fuel-loaded corridors with documented downstream ignitions; ForestOp counts ~31 confirmed corridor-fire events.
