## Multi-scale Mapping

**Multi-scale Mapping**
**Of**
**Fire Regime Condition Class**

## Why Map?

- Communication
- “Guidebook” characterizes FRCC but **not** spatially
- Spatially identify restoration opportunities

## 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

## 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

- Excessive

- Similar

- Deficient

- Relative Amount

| 34 to 66 | 2 |
| >66 | 3 |

## 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

## Reports

**Notes:**
Help State Fire Plan Working Group prioritize subwatersheds to do work.
Data must be consistent and quality must be suitable at the county/subwatershed levels.
Mid-scale data – NOT project level data.
Our purpose is to create data that will be useful for identifying project areas, and for prioritizing those projects
