The objectives of the prescribed fire were to provide for firefighter and public safety first, reintroduce fire back into a fire adapted ecosystem, and reduce fuel loadings during prescribed environmental conditions to allow for moderated fire effects. Fire managers were able to burn close to 1,250 acres of the 1,471 acre treatment unit.

Prescribed fire is a common method used to produce desired ecological effects in chaparral by mimicking the natural role of fire. Since prescribed fires are usually conducted in moderate fuel and weather conditions, models that accurately predict fire behavior and effects under these scenarios are important for management.

The first step to a successful prescribed burn is an analysis of forest property and the resource management plan. Determine the needs of each stand and what actions should be taken to meet these needs. Prescribed fire as well as other alternatives should be addressed and a decision reached regarding the preferred treatment.
Advancements for prescribed fire tools must (1) predict the impact of complex ignition patterns; (2) incorporate fire–atmospheric interactions; (3) predict most likely (instead of most extreme) fire behavior that occurs under marginal weather and fuel conditions; (4) accurately account for flanking and backing fire dynamics; and (5) link energy dose to prediction of fire effects.
In predicting outcomes of prescribed burning, it may be useful to compare the prescribed fire intensity cies, is seen as key to success (emery and gross 2005.
Most prescribed fires burned at a temperature under 80°f and relative humidity above 20 percent will keep the surface temperature below 800°f and soil temperature under 100°f up to two inches below the surface. Large logs and woody debris should be hand cleared form the site, if possible, to avoid long-term residency.

Please consider the following precautions and guidelines to help make sure your burn goes to plan.
The success of a prescribed fire is largely dependent upon thelevel of planning. Dozed lines should be constructed and arrangements made for equipment several weeks in advance. Finally, everyone should know their task on the day of the burn. Teamwork and communication are essential for conducting a safe, efficient prescribed fire.
Two types of fire simulation were used in this study: random and propagating, being used, respec- tively to simulate prescribed and unplanned fires. For prescribed fires, cells were selected at random and igni- tion success depended on availability for burning, as determined by the flammability variable.
A controlled or prescribed burn, also known as hazard reduction burning, backfire, swailing, in the wild, many trees depend on fire as a successful way to clear out the competition and release their seeds.

Grazing management in particular is vital to successful burning. Since suc- neighbors are certainly useful for predicting results from prescribed burning.
A prescribed burn plan is important for a safe and successful prescribed burn. A written burn plan includes the prescription for the stand and outlines.
A prescribed fire (pf) impact forecasting system has been developed to facilitate the dynamic management of air quality by modulating pf activity. Approximate location and size of fires are predicted based on the weather forecast and historic pf patterns. While burn permit data are used in georgia, satellite-derived (gbbep) fire data are employed.
Following consecutive prescribed burns for control actions among parts, it is easier to reliably predict success of a prescribed burn program, but can also.
In order to maximize the benefits of prescribed fires and balance the conflicting needs of ecological fire use, agricultural production, and effective smoke management, it is crucial that we understand how fires interact with the atmosphere and how this interaction affects smoke transport and dispersion so that viable tools can be developed for making go or no-go decisions for prescribed fires and for accurately predicting smoke distribution and concentration.
Smoke from prescribed fires is a complex mixture of carbon, tars, liquids, and forest service have been used to predict particulate emission factors and source.
Prescribed burning 2 backfire: a fire set to spread against the wind to burn more slowly and remove more vegetation and litter. Backfires are often used to create a black line for addition-al safety when a head fire is used on the same burn area. Fire boss: a person who supervises all phases of the ap-plication of a prescribed burn.
Naturally occurring fires have historically been an important factor in determining plant and animal distribution and composition in missouri. While natural fires are random and uncontrolled, prescribed burning is the process of applying a controlled fire to a predetermined area to meet certain goals and objectives.

“aras are trained to use and interpret the airfire tools for predicting when, where and how intense smoke is likely to manifest, but these tools can also be used by public officials, fire management staff, and others with the responsibility of informing the public about the timing and location of potential smoke episodes, both for prescribed fire and for wildfire.
Smoke produced from the burning vegetation will dissipate, and the overall success of meeting the burn objectives. Wind - prescribed fires behave in a more predictable manner when wind speed and wind direction are steady. Wind speed generally increases to a maximum in the early afternoon and then decreases to a minimum after sunset.
Computer simulation of prescribed fire effectiveness the changes induced on the fuel complex structure by a fuel treatment are measurable, and can be quantified in terms of changes in fire behaviour by computer simulation. The behave fire behaviour prediction system (andrews 1986) based upon the spread model of rothermel (1972) is fre-.
When planning a prescribed burn, consider the impact you want to achieve for your land management goals. Learning fire behavior will help burn managers predict potential impacts of a burn before it is conducted. There are several characteristics of fire that influence its impact. Keep in mind that weather, topography and fuel have roles in affecting fire characteristics.
