Fire plays a vital role in preserving forest health, vegetation maintenance, and certain ecosystems. Fire managers can use GIS to determine where to place prescribed fires on the landscape while considering fuel type, topography, wildlife habitat, and weather conditions. Modeling will show how a prescribed fire will behave and spread under a variety of conditions as well as the impact of smoke dispersion. With GIS, fire managers can select the appropriate prescription under which a prescribed fire will achieve the greatest benefit.
