Why elk and deer love burns
Fire clears the canopy and lets sun hit the soil. What comes back first is grasses, forbs and shrubs — high-protein new growth that elk and deer hammer from spring green-up through the fall. A burn is a food plot the size of a mountain, and it keeps producing for a decade or more. The catch is timing: a fresh burn is bare ground, and an old burn is timber again. The sweet spot is in between.
Read burn age like a local
On the map, burns are shaded by age: red means two years or younger (bare ground, skip it), green means three to fifteen years old (prime feed — this is what you are looking for), amber means older than fifteen (timber is reclaiming it, value fading). One limitation to know: the perimeter shows where the fire burned, not how hot it burned. A patchy, low-severity edge grows feed faster than a moonscape. Flip to the satellite basemap and look for green regrowth inside the perimeter before you commit to the drive.
| Burn age | What it looks like | How to hunt it |
|---|---|---|
| 0–2 years | Bare ground, ash, standing dead timber | Skip it — no feed yet, and snags are a hazard |
| 3–5 years | Explosive green-up, great feed, thin cover | Hunt the edges; animals feed inside and bed in adjacent timber |
| 6–15 years | Prime: feed plus edge cover and glassing lanes | Glass the open burn at first and last light |
| 15+ years | Timber reclaiming, openings closing | Value fading — look for the next younger burn |
How to use the burn scar layer
Turn on Burn scars under the Weather group in the Layers panel. Cross it with public land ownership and hunt unit boundaries so you are only scouting ground you can legally hunt, then flip between the satellite and topo basemaps: satellite shows you actual regrowth, topo shows you the benches and basins inside the burn where animals feed. The data is the interagency fire perimeter history — every mapped federal and state fire since 2005 — so it covers the whole West, not just the famous fires.
Hunt the edge, not the middle
Animals rarely live in the middle of a burn. They feed in the new growth and bed in the standing timber next door, which makes the burn perimeter the highest-value line on the map. Mark the transition where green burn meets dark timber — that is your morning and evening corridor. Burns also open up glassing lanes in country that used to be too thick to see through, so country you wrote off five years ago may be huntable now.
What the paid apps charge for this
Credit where it is due: the paid apps present fire data more slickly, and onX folds wildfire and recent-imagery layers into its $100-a-year Elite tier. But the underlying fire history is the same public interagency dataset either way — nobody owns it, and there is no technical reason a burn perimeter should cost a subscription. HuntTrack draws the same NIFC perimeters, shaded by the same age logic, for free. If a burn scar is the layer you open most, that is $100 a year you do not need to spend.
Timing it for the opener
Idaho's any-weapon deer season opens October 10 and elk runs October 10–24, so burns at mid elevation are at peak value right now — green-up is done, feed is cured but still nutritious, and animals are keying on it before the snows push them down. Have two or three burns picked per unit, because the obvious ones get company. And check current conditions before you go: perimeters are history, not active fire. A burn from 2021 can have a 2026 fire burning inside it, and closures follow the active fire, not the old line.
