Three primary factors always affect wildland fire behavior:

 

1. FUEL

The type and density of the surrounding vegetation provides the fuel to keep the fire burning. Not all plants and trees burn the same way. Some almost never burn, some burn at different times of the year, and others can burn almost anytime.

 

2. TOPOGRAPHY

The fire is affected by the steepness of slopes, valleys, saddles, ridges, and other land features in and around the building site. Vegetation varies widely between the extremes of south facing and north facing slopes.

 

3. WEATHER

Wind, temperature and humidity conditions affect each fire, and are highly variable in terms of time and location. Extended periods of low moisture increase the possibility of wildfire. Low humidity and high winds increase and intensify fire behavior, and wildland fires will often create their own internal weather conditions.

 

We have never been able to control the weather factor. But we can modify or accommodate topographical features, and we certainly can control the existing vegetation (fuel) on and around the property.
