  1. Unit 6: Prescribed Burning Lesson 1, 2, 3 International Paper Lesson VII

  2. Prescribed Burning is the best method for: • Hazard Reduction- reduction and control of forest litter and undergrowth • Hardwood control- kills undesirable species under 2” in diameter • Site Preparation- Most economical method for providing bare soil and full sunlight • Improving Wildlife Habitat- Reduces predator cover,exposes hidden food sources, increases low browse growth • Disease Control- The only practical control method of Brown Spot Needle Blight, possibly reduces Formes Annosus Root Rot • Improved Accessibility- Improved by reducing ground cover

  3. When planning a prescribed burn, several factors must be considered: • Fuel conditions • Weather • Season of the year • Time of day • Type of fire

  4. Fuel Conditions The amount of fuel, its arrangement, and combustibility (wind conditions, temperature, relative humidity)

  5. Weather Conditions- Available from the GFC, updated daily • Temperature- 20°F to 60°F for winter burning, 80°F and above in summer • Wind- Steady 2 to 10 mph, northerly direction • Relative Humidity- amount of moisture in the air, 30% to 50% • Rainfall- ½ to 1 inch, one week prior to the burn

  6. Other Conditions: • Season of the Year- Winter provides more predictable weather with less stand damage • Time of Day- Started by 10:00am and out by night

  7. Types of Fire For Prescribed Burning • Backfire- Started at a clear fire break or road, heading directly into the wind • Strip Head Fire- Uses narrow, parallel streaks of fire across a large area, set closely to reduce heat intensity • Flank Fire- Used as a supplement to other techniques, set into the wind at a right angle to catch up slowly burning patches

  8. Use of Maps To Plan the Fire • Used to select areas that need to be burned • Help to locate fire breaks in the burning area • Used to locate smoke sensitive areas near the possible burn site

  9. Smoke Sensitive Areas Include: • Airports • Highways • Communities • Resort or recreational areas • Schools • Hospitals • Factories • Stock barns or holding pens

  10. Don’t burn if: • Burn restrictions are in place • Undesirable weather conditions are present • Any smoke sensitive area is within ¾ mile downwind • The area has air pollution or visibility problems • There is a heavy fuel load • You plan to use head fire on two year old fuel • Transport wind speed is less than nine mph

  11. For a successful burn: • Get a reliable weather report, not a forecast, and observe the conditions first hand • Notify adjoining landowners and the GFC to obtain a burn permit • First do a small test fire • Start backfire close to the boundary, don’t start more fire than you can watch • Be aware of the changing wind conditions • Watch for stumps near the firebreak • Mop up any smoldering areas

  12. Evaluating the Burn • Check for crown scorch • Check the amount of litter consumed • Check hardwoods for bark cracks • Check for scorching of the bark • In spring, check for bark beetles
