Live fuel moisture (LFM) refers to the moisture content that is within living vegetation. It is the predictor of what vegetation will burn, the rate at which the vegetation will burn, and what levels of combustion the vegetation can withstand. Generally, in the case of a wildfire, the higher the LFM is, the lower the rate is of energy released.
Wildfire is a serious threat to lives, property and natural resources in California. The men and women of CAL FIRE make countless preparations and train frequently in order to be ready for all types of emergencies, including wildfires. Residents need to do the same.
Research and post-fire assessments have shown that property owners can protect their homes and businesses against wildfire by addressing three clear sources of vulnerability: materials and design features used in building the home or business, the landscaping vegetation located immediately adjacent to the home or business, and the general vegetation and other combustible materials and items on the property surrounding the home or business.
