The national database of state and local wildfire hazard mitigation programs
serves as a clearinghouse of information about nonfederal policies and
programs that seek to reduce the risk of loss of life and property through
the reduction of hazardous fuels on private lands. If

Objectives
Space Imaging (a remote sensing contract firm) and the Florida Division of Forestry, have completed a statewide assessment of wildland fire risk for Florida. The overall purpose of the Wildland Fire Risk Assessment is to identify the potential for wildfire within the State. More specific objectives include:
- the identification of areas in need of additional tactical planning,
- improved planning for firefighting resources,
- increased dialogue with residents to address community priorities and needs, and
- foster collaboration and cooperation among agencies to better define priorities and improve emergency response.
Methodology
The Wildland Fire Risk Assessment System (FRAS) combines indices of Wildland Fire Susceptibility and Fire Effects to generate a �Level of Concern� map. Data layers used to develop the Wildland Fire Susceptibility Index include: fuel and crown closure classifications and non-burnable areas from Landsat TM data, and topographic and fire weather data from existing data sets.
The Fire Effects Index uses data layers derived from a variety of existing data sets. These data included location of critical facilities, forest plantations, utility corridors, urban interface areas, roads, and firefighting resource locations; as well as, suppression cost-- based on soil and fuel types.
The Levels of Concern (LOC) were computed by multiplying the Wildland Fire Susceptibility Indices by the Fire Effects Indices. The LOC values were then assigned to nine categories of risk and mapped for each Florida Division of Forestry District.
Another component of FRAS is the Fire Response Accessibility Index (FRAI). The FRAI is a relative measure of travel time from the nearest fire station to reach a particular mapped cell. Values are assigned into one of six categories of time ranging from class 1 (greater than 120 minutes) to class 6 (0-14 minutes). Accessibility is based on the location of roads and wildland firefighting resource dispatch stations. The Fire Response Accessibility Index is coupled with the Levels of Concern data on District maps.
The fire behavior model, FlamMap is used in FRAS. FlamMap calculates the behavior of a fire occurring in each 30x30 meter cell under defined weather conditions given topographic, fuels, and crown closure data.
Applications
The Florida Wildland Risk Assessment System will provide the Florida Division of Forestry staff and other fire managers access to and use of published results data. The central product of the assessment is a series of spatial map data depicting the wildland fire risk situation in Florida. Using tools of the FRAS, reports and maps can be generated and printed. The maps generated from the Levels of Concern and Fire Response Accessibility data allows fire managers to more effectively prioritize pre-suppression efforts and improve firefighting preparedness.
An important capability of the FRAS is a feature that allows fire managers to conduct customized analyses of wildfire risk for an area of interest. Managers can create alternative scenarios for fuels mitigation planning through manipulations of data, such as resource locations, fire occurrence, or fuel models. Users can generate custom outputs such as reports for Wildfire Susceptibility, Levels of Concern, and Wildfire Accessibility.
