1. Multi-scale Mapping Of Fire Regime Condition Class

2. Why Map? Communication Guidebook characterizes FRCC but not spatially Spatially identify restoration opportunities

3. Why Develop a Tool? Most land managers lack GIS skills Many analytical tasks are repetitive Automation saves time, money, and reduces analytical errors Consistency & repeatability

4. Mapping Tool Objectives Compare existing condition to the reference condition Derive and spatially display departure indices Spatially identify restoration opportunities Report change necessary to mimic reference condition Conduct change detection between existing condition & proposed treatment ExcessiveSimilarDeficient Relative Amount

5. FRCC Mapping Tool Model inputs Spatial Data Biophysical setting (e.g., BpS) Existing condition of successional states (e.g., veg-fuel classes) Landscapes (e.g., reporting units) Tabular Data Reference condition table Landscape to BpS crosswalk Model outputs Spatial Data Veg-Fuel Class Percent Difference Veg-Fuel Class Relative Amount Veg-Fuel Condition Class: std level Veg-Fuel Class Departure Veg-Fuel Condition Class Landscape Departure Tabular Data Landscape Reports

6. Model Inputs Data Requirements –Continuous & consistent –Any scale (geographic extent & resolution) –Capable of discriminating BpS & Veg-Fuel classes Data Sources –Remote Sensing Satellite imagery Photo interpretation –Stand exam –Field-level mapping

15. Veg-Fuel Class Percent Difference The difference between existing veg-fuel class composition and the reference condition Indicates the veg-fuel classes that are most deficient to most excessive Most informative of all the indices Values: -100 to 100 Negative = too little; Positive = too much

16. Veg-Fuel Class Relative Amount Classification of the Percent Difference (lose information) Identifies excessive and deficient amounts of veg-fuel classes Suggests management scenarios –Maintain veg-class (similar) –Recruit veg-class (deficient) –Reduce veg-class (excessive) Trace Under RepresentSimilarOver Represent Abundant

17. Veg-Fuel Condition Class: Stand Level Classification of relative abundance Suggest management scenarios: –CC1 = maintain/recruit –CC2 = reduce –CC3 = reduce Useful for NFPORS reporting Percent Difference (%) Relative Abundance Std-level FRCC <25 Similar, Under Represented, Trace 1 25 to 75Over Represented2 >75Abundant3

18. Veg-Fuel Class Departure Signifies the overall departure across all vegetation-fuel classes within a BpS Values = 0 to 100 Useful for prioritizing BpSs for restoration

19. Veg-Fuel Condition Class (BpS-level) Classification of Veg-Fuel departure Stratified by BpS & landscape Represents the vegetation component of FRCC Vegetation-Fuel Departure (%) Vegetation-Fuel Condition Class <341 34 to 662 >663

20. Landscape Departure Area-weighted average of Veg- Fuel departure at lowest level of the landscape hierarchy Useful for prioritizing landscapes Values range between 0 and 100
