Detailed Description

Surprises relevant to future fire regime forecasts

by Jon E. Keeley, USGS Research Scientist

  • Historical variation in annual fire activity is tied to climate only in the montane forests.
  • Fires are largely insensitive to winter temperatures but significantly affected by spring and summer temperatures.
  • Future impacts of global warming on fire activity are largely dependent on the seasonal patterns of warming.
  • Lower elevation foothill shrublands and savannahs are not strongly affected by high temperatures in any season.
