About the Venues:

These four venues where selected because they are all sky islands in the Southwestern United States. These sites are prototype sites for phase 1 of FCS.

How the Model is Constructed

Below is brief descriptive information about the components that are incorporated into this model and the formula by which the components are weighted and combined into a final fire risk assessment map. For more complete information on the components, click the "About FCS-1" tab above or follow the 'More...' links below

Fire Probability Submodel Components (FPS)

Values at Risk Submodel Components (VRS)

Fuel Moisture Stress Index (FMSI)
Fire-season, time-dependent, fuel moisture conditions relative to those assessed from 1989 to 2003. For a relative measure at each pixel, we calculate departure from average via the negative z score.
More ...

 

Recreation Value (RV)
Based on a proximity/viewshed analysis of the top ten recreation activities in each venue (where they potentially were and the view from those locations).
More ...

Fire Return Interval Departure (FRID)
An index of the historical interval between fires for each vegetation type, and the years that have elapsed since the last fire.
More ...

 

Species Habitat Richness (SHR)
A proxy for the diversity of fauna, made up of a spatially explicit sum of the GAP-model habitats for mammals, amphibians, reptiles and birds.
More ...

Large Fire Ignition Probability (LFIP)
Probability of fires that will grow to greater than 250 acres within a vegetation type, standardized into a density map based on the total area in each vegetation class.
More ...

 

Property Value (PV)
Tabular housing data joined to census block-level data. Total housing value assigned proportionally based on area of intersection with the 1-km project grid.
More ...

Lightning Probability (LP)
Probability of a lightning strike, based on the spatially explicit density of lightning strikes per 100 ha per year in each research venue.
More ...

 

Perceived Landscape Values (PLV)
Personal perceptions of risk assigned to areas at risk of wildfire, based on participatory, map-based interviews at each of the WALTER venues.
More ...

Human Factors of Fire Ignition (HFFI)
Based on the spatial relationship between human activities and the location of human caused ignition.
More ...

 

For each cell in the component map, the fire hazard is calculated by the following formula

FCS-1 Fire Hazard = AHP weight of all fire probability components

AHP weight of relative fuel moisture index FMSI + AHP weight of fire return interval departure FRID + AHP weight of large fire ignition probabilityLFIP + AHP weight lightning ignition probability LP + AHP weight of human factors of fire ignition HFFI

+ AHP Weight for all fire risk components

AHP weight of recreation value RV + AHP weight of species habitat richness SHR + AHP weight of property value PV + AHP weight of perceived landscape value PLV

Each of the components is weighted in relationship to the others by the Analytical Hierachy Process
