LANDFIRE (LF) is pleased to announce the release of Early Spring Modeling Dynamic Fuels with an Index System (MoD-FIS) for the Great Basin and Southwest regions. MoD-FIS is seasonally modulated fuel model data that incorporates seasonal variability of herbaceous cover. These fine fuel measurements are then used to capture changes to fire behavior fuel models based on the current fire season herbaceous production.
Early Spring is a new addition to our seasonal suite of products and includes MoD-FIS Fuel Vegetation Cover (FVC), Height (FVH), and 40 Scott and Burgan Fire Behavior Fuel Models (F40) for the timeframe of February 1st - April 20th.

Background:
By 2011, there will be five versions of LF data products. Users need to be able to understand the strengths and limitations of each data product version in order to determine which version best fits their analysis and or application needs.
Advice:
Consult the Data Products Version Table to determine which version of LF data products best fit your analysis and/or application needs.
Background:
Previously, LANDFIRE (LF) Fire Regime Condition Class (FRCC) deliverables included both classed and continuous metrics of departure for vegetation and were called FRCC and FRCC Departure Index. These products will now be referred to as Vegetation Condition Class (VCC) and Vegetation Departure (VDEP). According to the FRCC Guidebook, FRCC is a combination of vegetation departure and fire frequency and severity departure. The layers previously referred to as Fire Regime Condition Class (FRCC) and Fire Regime Departure Index (DEP) were measures of vegetation departure, hence the name change. In addition, substantial changes in processing methods were used with LF 1.0.5 and LF 1.1.0 compared to LF 1.0.0 and these changes are described in the table below.
VCC and VDEP Version Comparison
| LF 1.0.0 | LF 1.0.5 and LF 1.1.0 | |
| Biophysical Settings (BPS) Units | Unique by map zone | Grouped (collapsed); refined in western rangelands using SSURGO soils data |
| Reference Conditions | LANDSUM | Vegetation Dynamics Development Tool (VDDT) |
| Succession Classes | Not mapped for any agricultural and urban EVTs | Not mapped for non-burnable agricultural and urban EVTs |
| Summary Units | ECOMAP Subsections and map zones | Hydrologic unit codes (HUCs 8, 10, 12) depending on Fire Regime Group* |
| Deliverables | Vegetation Departure and Vegetation Condition Class CONUS only | Vegetation Departure and Vegetation Condition Class CONUS, Alaska, and Hawaii |
*Southeast geoarea currently using ECOMAP Subsections
Advice:
Use caution when comparing VCC and VDEP from different versions because the methodology varies. Considerations are:
