Prescribed fire is one of the most effective tools we have in managing the intensity and spread of wildfires by reducing those fuels that would otherwise be available for a wildfire to consume. Wildfires that burn in areas where fuels have been reduced by prescribed fire cause less damage and are easier to control.Prescribed fires help reduce the catastrophic damage of wildfire on our lands and surrounding communities by: Safely reducing excessive amounts of brush, shrubs and trees. Encouraging the new growth of native vegetation. Maintaining the many plant and animal species whose habitats depend on periodic fire.Prescribed fire was the most effective technique, and under severe weather conditions reduced the average fireline intensity of a wildfire by 76% and its burned area by 37%, avoiding manifestations of severe fire behaviour.

Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil. Reducing this competition for nutrients allows established trees to grow stronger and healthier.
What are the advantages to prescribed burns?
Benefits of a safe and successful prescribed burn:
Removes old vegetation to make room for new growth. Shifts soil nutrients to a state more favorable to prairie species. Helps reduce the spread of invasive and pest species. Consumes excess fuel, such as dead and downed trees, reducing dangerous and intense wildfires.
Why don’t they do controlled burns in California?

How can controlled burns as seen with Native American cultural burns help protect ecosystems and reduce large catastrophic fires?
These control/prescribed burns effectively kill off invasive plants help restore natural habitat. The re- moval of the excess foliage will reduce fuel for forest fires and help reduce the effects of climate change, as well as help our state absorb more water into our meadows and replenish our groundwater.
What percentage of controlled fires get out of hand?
Approximately ninetynine percent of those burns were ‘successful’ (in that they did not report escapes or near misses). This can be viewed as an excellent record, especially given the elements of risk and uncertainty associated with prescribed fire. However, that leaves 40 to 50 events annually we should learn from.
Are prescribed fires bad?
Under low to moderate fire weather, prescribed burning can influence fire intensity and spread. Particularly if the burn is recent, it can slow or even stop a fire but not under extreme fire weather.
How do wildfires stop naturally?
While wind can help the fire to spread, moisture works against the fire. Moisture, in the form of humidity and precipitation, can slow the fire down and reduce its intensity. Potential fuels can be hard to ignite if they have high levels of moisture, because the moisture absorbs the fire’s heat.
Who said only you can prevent forest fires?
Smokey Bear’s famous slogan, “Only you can prevent forest fires,” was added in 1947 by the Wartime Advertising Council, known today as the Ad Council.
How do firefighters prevent wildfires?
Firefighters control a fire’s spread (or put it out) by removing one of the three ingredients fire needs to burn: heat, oxygen, or fuel. They remove heat by applying water or fire retardant on the ground (using pumps or special wildland fire engines) or by air (using helicopters/airplanes).
