Forest Fires in the United States: 8 February 2000
Forest Fires in the United States
8 February 2000
The Wildland Fire Assessment System is a contribution of “The Fire Behavior Research Work Unit”, Missoula (Montana USA). The broad area component of the Wildland Fire Assessment System (WFAS) generated national maps of selected fire weather and fire danger components. Fire Danger (Potential) is a normalized adjective rating class across different fuel models and station locations. It is based on information provided by local station managers about the primary fuel model, fire danger index selected to reflect staffing level, and climatological class breakpoints. Low danger (class 1) is green and extreme potential (class 5) is red.

The Morning Report of the SOUTHERN AREA COORDINATION CENTER is a narrative summary of fire activity within the Southern Area including number of fires, wildfires as well as prescribed burns, and area. “Wildland fire activity across the Southern Area picked up some over the weekend. Large fire activity occurred in Mississippi and Texas with initial attack activity fairly widespread. Prescribed fire activity has also increased. A crew and some miscellaneous overhead were mobilized to Mississippi.”
In following states the number of fires and area were reported on 7 February 2000:
ALABAMA: Accomplished 4 Rx burns for 2,380 ha Friday on 4 districts.
LOUISIANA: The Spring Creek fire was 100% contained on 2/4 at 115 ha.
MISSISSIPPI: Conditions are drying out and initial attack activity is increasing. Prescribe burning is being limited by the dry conditions. Temperatures this week are expected to warm up into the mid-60s with no rain in the forecast. The Fort Fire was caused by multiple arson fires that burned together. The fire is 100% contained at 368.3 ha. Aerial burnout was completed and crews are now mopping up and patrolling.
National Forest in Mississippi (MS-MNF): The Leno Road Fire is 100% contained at 81 ha and was caused by arson.
SOUTH CAROLINA: All areas of the state have moderate fire danger levels. Fire activity has increased for the state along the coast with some fires reported in other regions.
TEXAS: The Texas State Forest Service (TX-TXS) reported the Pecan Bayou fire is 100% contained at 162 ha. The fire is thought to be arson caused. The Cane Break Snake Fire is 100% contained at 162 ha and was also arson caused.
According to the INCIDENT MANAGEMENT SITUATION REPORT three categories of fires are distinguished, such as:
1. Fires*
2. Prescribed Fires
3. Wildland Fire Use Fires**
* This classification corresponds to the category “wildland fires” as defined by the National Interagency Fire Center (NIFC)
** A brief excursion to wildland fire terminology:
Wildland Fires: Fires occurring on any tpye of vegetation, regardless of ignition sources, damages or benefits.
Wildfire: Any uncontrolled wildland fire which (1) may require suppression response, or (2) any uncontrolled wildland fire which meets management objectives and is declared as a Wildland Fire Use Fire (see below) or syn. Prescribed Natural Fire or Prescribed Fire.
Prescribed Fire: Occasionally also called management-ignited fire, or prescribed burning, is a controlled application of fire to vegetation in either their natural or modified state, under specified environmental conditions which allow the fire to be confined to a predetermined area and at the same time to produce the intensity of heat and rate of spread required to attain planned resource management objectives.
Wildland Fire Use Fire: Naturally ignited fire which is managed to achieve resource benefits under close supervision (syn. Prescribed Natural Fire)
Currently, Wildland Fire Use Fire data are not available. The differentiation of the above mentioned three fire classes do not point out clearly for the moment, whether the classified wildland fires included prescribed burned areas.

Remarks on Prescribed Burning
At this time of the year prescribed burning operations are conducted routinely.
Fire is an important natural tool for ecosystem management. It can reduce dense vegetation improving wildlife habitat and lessening the potential for large, wildfire disasters. Land managers are directed to prepare a prescribed fire/burn plan for every area of public land that can burn. Some areas require total suppression while others will benefit from a wildland fire. Those areas that will benefit from a fire can be treated by a prescribed fire.
Especially, for the moment, in the southern and southeastern regions of the United States prescribed fire activities will be carried out in the following weeks and months. In this case, fire signals on satellite images can be traced back to this kind of land management activities.
In the Prescribed Fire Position Paper of the Forest Protection Bureau by the Division of Forestry in Florida, prescribed fire activity is described as a land management application that is essential to the practice of forestry, management of wildlife, preservation of endangered plant and animal species, improvement of range conditions and reduction of wildfire damage in the wildland/urban interface areas. While there is general public and landowner concern with increased smoke, reduced air quality, and liability; the general public and landowners benefit significantly from the reduction of devastating wildfire, improved wildlife habitat and forage, preservation of endangered and threatened plant and animal species, and improved management of forest resources. The prospect of severe reductions in the utilization of this management tool is of major concern to Florida’s natural resource managers and conservationists due to the subsequent loss of derived public and private benefits. They suggest the need for legislative attention.
Another report on nation-wide prescribed burning in the U.S.A. was published in International Forest Fire News No.19 (September 1998).
