The Wildfire Risk Reduction Grant Program Effectiveness Assessment and Program Overview Brett Wolk, Chad Hoffman, Claire Griebenow, and Tony Cheng January 14 th, 2015, Front Range Roundtable LR Team Meeting, Lakewood, CO Colorado Forest Restoration Institute, Colorado State University, Fort Collins, CO ,
Wildfire Risk Reduction Grant Program 2013 Colorado State Assembly authorized $9.8 million from general funds for fire mitigation. Non-federal lands in Colorado match required (25% hard match) Vegetation Management – Very Flexible – Large fuel breaks – Defensible space – Egress/Ingress – Equipment and Infrastructure
& & Fuel Break Roadside D-space Equipment /Other All WRRG Awards Through September
Wildfire Risk Reduction Grant Program The Future of the WRRG Program – Hearing Tomorrow!!
Colorado Forest Restoration Institute Role in the WRRG Program Additional effectiveness assessment – more than a quick walk through and pictures. Purpose: To inform the DNR and fire/forestry practitioners about fuel hazard mitigation effectiveness and ways to improve future treatments. – Audience: State/Politicians Stakeholders and managers
Monitoring and Assessment Goals: Education and Outreach…

Predicts relative fire hazard from 0 (low fire hazard) to 9 (high). Peer reviewed. Free. Easy to use and interpret results. Comprehensive fuels assessment. Applicable across vegetation types and geography. Fuel Characteristic Classification System FCCS
Fuels Characteristic Classification System Fire Potential Ratings (0-9) PrePost Surface Fire Behavior Potential 33 Summary surface fire behavior potential, calculated as the maximum of spread potential and flame length potential scaled to an index between 0-9. Reaction potential 2. 1 Approximates the potential reaction intensity (energy released per unit area and time). Spread potential Proportional to the no-wind rate of spread in surface fuel (distance per unit time). Flame length potential Proportional to fireline intensity or flame length. Crown Fire Potential 31 Weighted average of crown fire subpotentials. Crown fire initiation potential Potential for fire to reach canopy layer. Crown-to-crown transmissivity potential Potential for fire to carry through a canopy. Crown fire spreading potential Relative index of crown fire rate of spread. Available Fuel Potential 21 Sum of fuel loadings in all combustion phases scaled to an index between 0-9. Flame available fuel potential Sum of fuel loadings available for the flaming phase of combustion (in units of 10 tons/acre). Smoldering available fuel potential 0. 4 Sum of fuel loadings available for the smoldering phase of combustion (in units of 10 tons/acre). Residual available fuel potential Sum of fuel loadings available for the residual smoldering phase of combustion (in units of 10 tons/acre).
Pre vs. Post Treatment Surface Fuels Herbaceous Shrubs Trees Accomplishments to date: Round 1 and 2 funding only. 38 of 52 grants with at least 1 site visit. 21 of 52 grants with plots. 32 treatment units with plots. ~270 pre-treatment plots statewide. Developing Sampling Methods for FCCS Inputs

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.
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. WRRG Program Goals
Are Fire Hazard Mitigation Goals Met? Mitigation Goal: Tree’s Survive Post Fire Reduce Post Fire Erosion Increase Fire Suppression Safety and Effectiveness Objective: Reduce wildfire hazard through vegetation management.

1. Utilization Opportunities 2. Prescribed Fire SOLUTIONS
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.
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.
