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.
No two fires ever look the same, and it’s hard to predict how various forest and environmental conditions will affect outcomes. Fire agencies around the country still worry about their ability to control prescribed burns. It’s one reason the practice remains infrequent among forest managers in the west.

Fire suppression is safer, more effective and costs less in areas with a recent history of controlled burning.
Please consider the following precautions and guidelines to help make sure your burn goes to plan.
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.

This objective is necessay to evaluate the success of the burn. To show the success, or lack thereof, of a prescribed burn, a photograph can be taken before, directly after, and one year following the burn. Objectives for a prescribed burn often include one or more of the following:.
Prescribed burn is a common practice in farming communities for burning agricultural debris. Prescribed fire is also used by land managers for fuel reduction. Over the past two decades, the use of prescribed fires has increased to counteract a history of fire suppression that has left many forests susceptible to catastrophic wildfires due to the buildup of fuels.

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.

2017) that while prescribed fires emit smoke, daily emissions can be exponentially greater during a major wildfire.
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.
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.
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.
Finally, we decided to focus on the prescribed fire projects instead of the individual publications because some of the projects, especially the large, long-term studies, produced multiple publications. Ultimately, we settled on 50 articles/reports from 32 prescribed fire projects conducted in 15 states for this meta-analysis project.

Prescribed fires behave in a more predictable manner when windspeed and direction are steady. For underburning, the preferred range for windspeed in the stand is 2-5 km/hr (at eye level) for most fuel and topographic situations. With high winds, heading fires spread too rapidly and become too intense.
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.
