Prescribed or controlled burning (back burning) is a technique sometimes used in forest management, farming, or prairie restoration. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest. Some seeds, such as sequoia, remain dormant until fire breaks down the seed coating.

In industrialized countries, controlled burning is usually overseen by fire control authorities for regulations and permits. The party responsible must delineate the intended time and place. Obtaining a permit may not limit liability if the fire burns out of control.

Another consideration is the issue of fire prevention. In Florida, during the drought in 1998, catastrophic wildfires burned numerous homes. But forestry managers note that the underlying problem was prior cessation of controlled burning, due to complaints by homeowners.

Controlled burns are sometimes ignited using a tool known as the driptorch, which allows a steady stream of flaming fuel to be directed to the ground as needed. Variations on the driptorch can be used such as the helitorch, which is mounted on a helicopter, or other improvised devices such as mounting a driptorch-like device on the side of a vehicle. A pyrotechnic device known as the fusee can also be used in ignition.

For the burning of slash, waste materials left over from logging, there are several types of controlled burns. Broadcast burning is the burning of scattered slash over a wide area. Pile burning is gathering up the slash into piles before burning. These burning piles may be referred to as bonfires. High temperatures can harm the soil, damaging it physically, chemically or sterilizing it. Broadcast burns tend to have lower temperatures and will not harm the soil as much as pile burning, though steps can be taken to treat the soil after a burn. In lop and scatter burning, slash is left to compact over time, or is compacted with machinery. This produces a lower intensity fire, as long as the slash is not packed too tightly. However, soil may be damaged if machinery is used to compress the slash. Slash is a forestry term that refers to coarse and fine woody debris generated during logging operations or through wind, snow or other natural forest disturbances. ...

Controversy

George D. Kessler, professor of forestry, and extension forester at Clemson University notes that controlled burning reduces fuels, may improve wildlife habitat, controls competing vegetation, improves short term forage for grazing, improves accessibility, helps control tree disease, and perpetuates fire dependent species. In old growth longleaf pine forest, it helps maintain habitat for endangered Red-cockaded Woodpeckers in their sandhill and flatwoods habitats. However many scientists disagree with such a simplistic approach, and indicate that each forest must be assessed on its own merit. A decidous beech forest in Slovenia. ...

There are critics of controlled burns as a forest management practice. Barbara A. Lund believes that burnings are harmful to the environment. She has asserted that controlled burning may be harmful to eastern hardwood forests and that many animals die during the burns.[1]


Agricultural use

In addition to forest management, controlled burning is also used in agriculture. In the developing world, this is often referred to as slash and burn. In industrialized nations, it is seen as one component of shifting cultivators as a part of field preparation for planting. Often called field burning, this technique is used to clear the land of any existing crop residue as well as kill weeds and weed seeds. Field burning is less expensive than most other methods such as herbicides or tillage but because it does produce smoke and other fire related pollutants, its use is not popular in agricultural areas bounded by residential housing. In the United States, field burning is a legislative and regulatory issue at both the Federal and state levels of government. First used significantly in the Neolithic Revolution (ie. about 9-11,000 years ago at the end of the last ice age when hunter gatherers turned to farming). Assarting in Finland in 1892 Slash and burn (a specific practice that may be part of shifting cultivation or swidden-fallow agriculture) is an agricultural procedure widely used in forested areas. ... Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned. ... This does not cite any references or sources. ...


Controversy

In Oregon, field burning has been widely used by grass seed farmers as a method for clearing fields for the next round of planting. The Oregon Department of Environmental Quality began requiring a permit for farmers to burn their fields in 1981, but the requirements became stricter in 1988 following a multi-car accident[2] in which smoke from field burning near Albany, Oregon obscured the vision of drivers on Interstate 5, leading to 23-car accident in which seven people died and 37 were injured. [3] This resulted in more scrutiny of field burning and proposals to ban field burning in the state altogether.[4] Official language(s) (none)[1] Capital Salem Largest city Portland Area  Ranked 9th  - Total 98,466 sq mi (255,026 km²)  - Width 260 miles (420 km)  - Length 360 miles (580 km)  - % water 2. ...
