1. Landscape Treatment Priority Analysis Sequoia and Kings Canyon National Parks

2. Fuels Treatment - Where are the Priorities ? Combine several analysis layers to better visualize areas in need of treatment. –What are the ground conditions - hazardous? –What’s at risk - developments in high hazard areas? –Where to apply/not apply prescribed fire & why

3. Combine Existing Analyses Hazard Ignition Risk Ecological Need ? Mineral King Project Area (East Fork Watershed)

4. Additive Priority Analysis

5. Analysis Inputs Firefighter Safety Hazard Analysis Presence of Development Fire Return Interval Departure “FRID” Ignition Risk Presence of Sequoia Groves –additional priority, could be cultural areas, etc.

6. Standard“Hazard” Model Once fire ignites High Hazard Moderate Hazard Low Hazard

7. Hazard Inputs Fuel models Aspect Slope Elevation Accessibility of Roads (additional safety) –Measure of ability for resources to get in/out of areas

8. Reclass Hazard Inputs Fuel models - Heavy = High,etc Aspect - South = High Slope - 70 degrees is High Elevation - low elevation is high hazard

9. Road Accessibility Low hazard –Primary/Secondary Roads Moderate hazard –Unimproved/unpaved roads High hazard –4-WD, trails, dead-end (1-way in/out), or areas > 420 meters(1/4 mile) from road

10. Apply weights to Hazard Inputs Fuel models - High fuel hazard more important than low elevation..

11. Add Hazard Inputs & classify Increasing Hazard Class 2 Class 1Class 8

12. Firefighter Safety - “Hazard” Once fire ignites

13. Developed Areas Buildings data buffered to 250 feet. County assessors plats used as surrogate for buildings within park in-holdings areas. Could simply delineate area on map and digitize. Presence multiplied by FFTS value.

14. Ecological Need for Fire Fire Return Interval Departure aka “FRID” Demonstrates how many fire return intervals a vegetation type has missed. Also a measure of extreme fuel buildup Surrogate for Condition Classes –Extreme/High - class 3. –Moderate - class 2 –Low - class 1

15. Fire Return Interval Departure FRID = TSLF - RI max RI max

16. Vegetation

17. Determine Historic Fire Return Intervals

18. Vegetation Reclass Table RI max = Maximum Fire Return Interval

19. Historic Fire Return Intervals

20. Fire History Assumption when no data Conservative date = 1899 2001 - 1899 = 102 (TSLF)

21. 76-7 = 9.9 7

22. Fire Return Interval Departure FRID = TSLF - RI max RI max

23. FRID Source Data Summary Vegetation map Fire Return Intervals look-up table Fire history –1921-2002 –Assumption with no data (last fire was 100 years ago)

24. Ignition Risk - Data available Dept. of Interior fire records (1202’s) –Need UTM’s - lat/long format difficult to translate but rumor says that’s changing. Local fire history database - generate center points if actual ignition location unknown. Density function - graphically depicts points that might overlap.

25. Risk - Probability of Ignition

26. Sequoia Groves Presence - use FRID value as additive –A little extra push to treat these areas –Other parks may have other values they wish to make priority Other Values ? - Cultural sites, etc.

27. Priority Model - Range of Values

28. What does the intersection look like? Hazard Risk EcologicalNeed ?? ?

29. Landscape Treatment Priority Analysis Hey, look here

30. Assumptions for Priority Analysis Fire Return Intervals are relatively accurate Aspect makes a difference - work in progress to refine fire return intervals Vegetation map is accurate Fire history is accurate

31. Data Needs / Limitations Vegetation Map (FRID, Fuels) Fire History - 1202’s and/or polygons (ignition points and area burned for FRID) Fire Return Interval - for each veg type Infrastructure/Developed Areas DEM’s (elevation, slope, aspect for Hazard) Roads - categorize for accessibility Ground truth - data are not perfect!!!

32. Future Updated Vegetation map - basis for analysis Refine Fire Return Intervals - aspect Refine priorities and weighting schemes Tools/Extensions to run analyses faster Web based analysis - select parameters Remote Sensing - Fuels, succession models Other disturbance regimes - grazing, disease, mechanical treatments
