1. Fuel Management Objectives within Dry Forest Landscapes on the Okanogan-Wenatchee NF Dr. Richy J. Harrod Okanogan-Wenatchee National Forest

5. Ecological Restoration Ecological restoration aims to enhance the resilience and sustainability of forests through treatments that incrementally return the ecosystem to a state that is within a historic range of conditions (Landres et al. 1999). The process of assisting the recovery and management of ecological integrity (Society for Ecological Restoration).

6. Okanogan-Wenatchee NF Dry Forest Strategy 2020.3 – FSM Policy 1.All resource management programs have a responsibility for ecological restoration… Emphasize restoration efforts in the dry and mesic forests Provided recommendations for types of and placement of treatments Key emphasis on integration of resource values

7. Relatively open stands of ponderosa pine developed dense Douglas-fir, white fir, and grand fir understories.

8. Goals of Fuel Management Change how fire behaves within stands and across landscapes Create stands and landscapes that are resilient to fire Mitigate fire hazard in the wildland/urban interface

9. Fuel Management Objectives Reduce surface fuels Increase height to live crown Decrease crown density

10. Fuel Management Objectives Treatment sequence –Harvest, pile, pile burn, underburn –Thin, pile, underburn –Underburn Can use FCCS to determine sequence

12. Reduce Surface Fuels In dry forest types, average of 3-5 tons/acre within stands Loading should be discontinuous, variability is desired.

13. Reduce Surface Fuels Goal is to reduce flame length –A measure of fire intensity which determines fire severity –Long lengths leads to high torching potential

14. Reduce Ladder Fuels Decrease potential for torching –Eliminate branches on large trees –Reduce understory density Variability throughout stand is desirable

15. Decrease Crown Density Reduce potential for crown fire –Harvest or thinning –Torching through prescribed fire Variability is desirable Retain large fire resistant trees!

16. Hard to Meet Restoration Objectives

19. LANDSCAPE CHARACTERISTICS

20. Priority Treatment Areas- developed using Analytical Hierarchy Process Weight factors Applied at the landscape scale.

21. Restoration Approach Determine where on the landscape to place your treatments.

22. Summary Treatments need to be strategically placed on the landscape Stand level treatments should focus on three principles of fuel management Treatments need to consider the importance of spatial patterns, fire tolerant structures, and species composition Important to integrate resource objectives, not about reducing fuels everywhere.
