Overall Preliminary Conclusions For WRRG Effectiveness Assessment
• Clear objectives = better mitigation.• Most current treatments focus on reducing
crown fire hazard, and are successful at that objective when aggressive.
• Surface fuels and slash disposal is a barrier to fire mitigation success.– Many treatments do not change and/or increase
surface fuel quantity and continuity.
![Page 20: The Wildfire Risk Reduction Grant Program Effectiveness Assessment and Program Overview Brett Wolk, Chad Hoffman, Claire Griebenow, and Tony Cheng January](https://reader036.vdocuments.us/reader036/viewer/2022062518/56649f355503460f94c540f6/html5/thumbnails/20.jpg)
Objective: Reduce wildfire hazard
through vegetation management.
Shared Treatment Goals:
– Tree’s Survive Post Fire.
– Reduce Post Fire Erosion.
– Increase Fire Suppression Safety and
Effectiveness.

Why Should Roundtable Care?
• Lots of work on private lands. Landscape Scale.
• Private Lands becoming receptive to monitoring and LEARNING.
• WRRG monitoring program has created hunger for information.– Efficient and effective treatment methods.
![Page 26: The Wildfire Risk Reduction Grant Program Effectiveness Assessment and Program Overview Brett Wolk, Chad Hoffman, Claire Griebenow, and Tony Cheng January](https://reader036.vdocuments.us/reader036/viewer/2022062518/56649f355503460f94c540f6/html5/thumbnails/26.jpg)
Opportunities for Learning Exchange
Private• Negotiate individual tree
removal with homeowners.• No NEPA – opportunity for
innovative techniques, also continue to repeat failures.
USFS• Negotiate landscape
treatments with public groups.• NEPA moderates management
– slows advances, but ensures minimum best practices.

Options for Woody Slash Disposal
• Mastication• Chipping• Slash pile burn• Broadcast burn• Leave branches on site (lop and scatter)• Pay to have it hauled out (stewardship contract)• Find a buyer• Give away for free
All options have ecologicalbenefits and drawbacks
