Hazard Tree Safety “Up The Ante”and “An Interactive Study”
Presented To:International Wildland Firefighter Safety Summit Toronto, Ontario November 18, 2003 Paul Chamberlin Interagency Fire Operations Safety Aerial Fire Depot Missoula, Montana
Recent Events • Bitterroot National Forest • Kentucky, Plumas Hotshot • Missionary Ridge Fire • Inyo National Forest • Helena Hot Shot- 30 Mile Fire • 2001 Northern Rockies, 3 trees hit 4 people in 6weeks • 2003 Broken ankle, broken neck, and one tree injured 3 people • Several other injuries and many close calls nationwide
In the Northern Rockies, these situations were well managed • Experienced and dedicated supervisors • Crews well briefed • Were looking for snags • The snags involved were just missed!
Even when properly managed, we are still having problems -Forest health issues are not soon going away -We have hundreds of thousands of acres of burned forests
Even when properly managed, we are still having problems -Therefore what we are doing is inadequate -We must ‘Up The Ante’ for snag and hazard tree safety
Guiding Thoughts • Driving along parked cars • Drifting into the oncoming lane • We recognize indicators with ingrained knowledge • We need a tool chest full of mitigations
Guiding Thoughts • Query the Workforce • Consolidate Their Ideas • Get the Word Out
“Up the Ante” a Process • Each Unit to review existing rules and guidelines. • Each individual ‘Gut Check’ • Group ‘Brainstorm’ new ideas • E-mail findings to central address • At each unit, prepare a Tree Hazards briefing for incoming resources.
Getting There- a Process • Line officers to demonstrate strong, visible and active leadership • Achieve employee focus and buy-in • 2 hour sessions on each unit • Product of each session gathered centrally • Ideas and suggestions gleaned for common threads and new ideas
Program Goals • All functions • Trails • Fire • Timber • Researchers • Engineers • Contractors • Public
Program Goals • All functions • Raised Awareness, Mental Engagement, Ownership, Buy-in, Strong Leadership • Well known indicators of tree structural defects • Effective mitigations throughout • Reinvigorate 1993 National Snag Hazard Report
Current Status • NWCG FAST 2002 National Emphasis Topic • Northern Rockies OSHA Mitigation • R-1 Safety and Health Leadership Team annual emphasis topic • NRCG says go • USFS National Fire Safety Council support for all USFS fire folks
Success is achieved when: • Wise, concise, and achievable concepts become part of the culture
Success is achieved when: • Wise, concise, and achievable concepts become part of the culture • These concepts become regular briefing elements and are found in common language, in manuals and guidebooks
Success is achieved when: • Wise, concise, and achievable concepts become part of the culture • These concepts become regular briefing elements and are found in common language, in manuals and guidebooks • Conscious and deliberate procedures and behaviors end tragic hazard tree accidents

Hazard Tree Awareness An Interactive Study of Hazard Tree Indicators
Hazard Tree Awareness Presented with a sincere concern for your safety, by Northern Rockies Federal Land Management Agencies.
Interactive Discussion Throughout this program, discuss each example as a risk to: • Someone walking or driving by. • A short term camp or work site. • A permanent camp site, or facility.
Interactive Discussion Throughout this program, discuss each example as a risk to: Someone walking or driving by. A short term camp or work site. A permanent camp site, or facility. • Where a significant risk exists: • Describe appropriate options. • Describe events that will change the risk level.
Tree Basics • Anything that causes stress on a tree will weaken it. • Tree Stresses are Cumulative and Inter-related. • The structural integrity of a tree is affected when these stresses result in damage and or decay. • Very elementary – the scientific names of insects and disease agents are not needed.
Objective:Looking for the Indicators Indicators of tree structural issues Changing conditions and changing risk levels. Assessment tools to help ascertain risk.
Objective:Looking for the Indicators in the Crown, on the Bole, at the Roots and Tree Base, and Changing Conditions.

Crown Indicators • Structural Characteristics observed in the Crown. • Dead Tops • Broken Tops • Fire Damage • Forks • Defective and Hanging Limbs • Leaning Trees • Crown Indicators of Root Defect • Loss of needles / leaves, thinning crowns • Discoloration • stress cone / seed crop
Structural Characteristics - Crown • Dead Trees and Broken Tops
Structural Characteristics - Crown • Fire Damage to Crown of Tree
Structural Characteristics - Crown • Witches Brooms are an example of defective limbs. • Heavy snow, wind, or other conditions can cause these limbs to break and fall
Structural Characteristics - Crown Dead branches
Structural Characteristics - Crown Long standing leaning trees have grown a vertical top • Developed re-enforced root systems to compensate • Are less of a hazard than….
Structural Characteristics - Crown …. recent leaning trees
Crown Indicators of Root Defect • Loss of needles/leaves, thinning crowns, dieback
Crown Indicators of Root Defect • Stress cone
Bole Indicators • Indicators of Butt, Stem and Bole Defects: • Decay • Swelling • Cracks and Splits • Fire Scars • Burned out bole
Indicators of Butt, Stem, Bole Defects • Decay - Rots
Indicators of Butt, Stem, Bole Defects • Decay - Conks
Indicators of Butt, Stem, Bole Defects • Bole swellings
Indicators of Butt, Stem, Bole Defects • Cracks and Splits - Lightning
Indicators of Butt, Stem, Bole Defects • Cracks and Splits - Windshake
Indicators of Butt, Stem, Bole Defects • Cracks and Splits – Frost Cracks
Indicators of Butt, Stem, Bole Defects • Burned bole of tree, adjacent to road
Root and Tree Base Indicators • Observed at the base of the tree • Basil Resin Flow • Mushrooms • Butt Rots • Wind Throw • Fire Damage • Burned root • Water • Soil Erosion • Compaction • Sprung Roots
Indicators of Root Defects • Basil Resin Flow
