Start with a fire regime
A fire regime describes recurring patterns such as frequency, season, size and severity. Those patterns differ among grasslands, shrublands, forests and wetlands, and they can change as climate, fuels and land use change.
Calling a species “fire adapted” does not mean every fire produces a positive outcome. A fire outside the historical range of conditions, or repeated before recovery, can create different effects from a periodic event within that range.
Intensity and severity are not synonyms
Fire intensity describes energy released by the fire. Burn severity describes ecological effects, often including vegetation change and soil response. A map of vegetation severity is a useful baseline, but delayed mortality and below-ground effects require follow-up.
Look for a mosaic
Real fire footprints can contain unchanged, low-, moderate- and high-severity patches. Refuges and surviving biological material may influence recolonization, while exposed areas may face different erosion or seed-source constraints.
Safety comes first
Do not enter closed or unstable burned areas to collect observations. For current conditions, use local fire authorities and land-management agencies. Renewal Ecology is not an emergency service.
