Reasons to Burn
- Reduce hazardous fuels
Forest fuels accumulate rapidly in pine stands. In 5 to 6 years heavy roughs can build up, posing a serious threat from wildfire to all forest resources. Prescribed fire is the most practical way to reduce dangerous accumulation of combustible fuels under southern pine stands. Wildfires that burn into areas where fuels have been reduced by Rx fire cause less damage and are much easier to control.
- Prepare sites for seeding and planting
Rx fire is useful when regenerating southern pine by direct seeding, planting, or natural regeneration. On open sites, fire alone can expose adequate mineral soil and control competing vegetation until seedlings become established.
- Improve wildlife habitat
Rx fire is highly recommended for wildlife habitat management where loblolly, shortleaf, longleaf, or slash pine is the primary overstory species. Periodic fire tends to favor understory species that require a more open habitat. A mixture of burned and unburned areas tends to maximize "edge effect", which promotes a large and varied wildlife population. Deer, dove, quail, and turkey are some of the game species that benefit from Rx fire.
- Manage competing vegetation
Low-value, poor quality, shade tolerant hardwoods often occupy or encroach upon land best suited to growing pines. Unwanted species may crowd out or suppress pine seedlings. In most situations, total eradication of understory is neither practical nor desirable. However, with the careful use of Rx fire the understory can be managed to limit competition with desired species while at the same time providing browse for wildlife.
- Control insects and disease
Brownspot disease is a fungal infection that may seriously weaken and eventually kill longleaf pine seedlings. Once the seedlings become infected, burning is the most practical method of disease control. Any type of burning that kills the diseased needles without killing the terminal bud is satisfactory. Rx fire has been successfully used under very exacting fuel and weather conditions to control cone insects such as the white pine cone beetle, while the pest is overwintering in cones on the ground. Rx burning costs much less than traditional chemical control methods used to control this beetle.
- Improve forage for grazing
Rx burning improves grazing in open pine stands on the Coastal Plain. Low intensity burns increase availability, palatability, quality, and quantity of grasses and forbs.
- Enhance appearance
Rx burning improves recreation and aesthetic values. Burning maintains open stands, produces vegetative changes, and increases numbers and visibility of flowering annuals and biennials. Rx burning also maintains open spaces such as mountain balds, and creates vistas.
- Improve access
Burning underbrush prior to the sale of forest products improves the efficiency of cruising, timber marking, and harvesting. The reduced amount of fuel helps offset the greater risk of wildfire during harvesting. Moreover, the improved visibility and accessibility often increases the stumpage value of the product.
