Tree Climbing and saftey in Tree Care

 By Founder & Teaching Arborist, School of Trees 

    Sean Harman ISA Certified Arborist MA-6197A


Tree Climbing Techniques & Proper Work Positioning

Professional tree climbing is not about getting into the tree — it is about maintaining control, stability, and safety while performing precise work. Proper climbing technique reduces fatigue, prevents injury, protects the tree, and allows for accurate pruning cuts.

Every movement in the tree should be intentional and repeatable.

 

Core Principles of Professional Tree Climbing

All climbing systems and techniques must support these fundamentals:

  • Continuous fall protection
     
  • Stable work positioning
     
  • Redundant attachment when cutting
     
  • Minimal damage to tree tissue
     
  • Efficient movement with minimal strain
     

If a position feels rushed, unstable, or awkward, it is not acceptable.

Tie-in Point selection

 

Tie-In Point (TIP) Selection

Your tie-in point determines your safety, reach, and work quality.

A proper TIP should:

  • Be structurally sound and free of defects
     
  • Have a favorable branch angle
     
  • Allow vertical and lateral movement
     
  • Minimize rope movement across bark
     
  • Be positioned above the work whenever possible
     

Avoid tie-in points with:

  • Cracks, decay, or conks
     
  • Bark inclusions
     
  • Excessive leverage or movement

 

Two Points of Attachment (Critical Safety Rule)

Whenever cutting, climbers should maintain two independent points of attachment.

Examples:

  • Primary climbing line + adjustable lanyard
     
  • Primary line + secondary climbing system
     

Two points of attachment:

  • Prevent swing falls
     
  • Reduce shock loading
     
  • Increase cutting stability
     

Never rely on a single attachment point while operating a saw.

 

Body Positioning & Balance

Good work positioning keeps your body centered, supported, and out of the cutting plane.

Best practices:

  • Keep hips below the anchor point
     
  • Maintain three points of contact whenever possible
     
  • Position your body to the side of the cut, not directly behind it
     
  • Avoid overreaching — reposition instead
     

If you cannot cut comfortably without stretching or twisting, reposition first.

Rope and Lanyard

 

Lanyard Use for Work Positioning

A lanyard is a work positioning tool, not just a backup.

Use your lanyard to:

  • Stabilize yourself at the work position
     
  • Reduce load on your primary line
     
  • Control body orientation
     
  • Maintain redundancy while cutting
     

Lanyards should be adjusted deliberately — not left loose or forgotten.

 

Rope Management & Protection

Poor rope management creates hazards for both the climber and the tree.

Best practices include:

  • Keeping climbing lines out of the cutting zone
     
  • Avoiding running ropes across sharp unions
     
  • Using friction savers or cambium protectors
     
  • Managing slack intentionally
     

Never cut toward:

  • Your climbing line
     
  • Your lanyard
     
  • Any loaded rope

Our Process

 

Movement & Repositioning in the Canopy

Efficient climbers move methodically, not reactively.

Key techniques:

  • Advance the rope before moving laterally
     
  • Use redirects to maintain favorable rope angles
     
  • Reset work positions instead of reaching farther
     
  • Anticipate the next cut before moving
     

Good movement reduces fatigue and improves cut accuracy.

 

Cutting Position Awareness

Every cut should be made with:

  • A stable stance
     
  • Clear escape positioning
     
  • No loaded rope in the cutting path
     
  • Full control of the saw
     

Never cut:

  • One-handed
     
  • While off-balance
     
  • While standing on unstable limbs
     
  • Above your attachment points
     

A stable cut is a safe cut.

fatique management in tree care

 

Fatigue Management & Efficiency

Fatigue leads directly to mistakes.

Reduce fatigue by:

  • Using efficient rope systems
     
  • Maintaining proper body alignment
     
  • Taking micro-breaks
     
  • Repositioning instead of muscling through
     

Professional climbers work smarter, not harder.

 

Common Climbing Mistakes to Avoid

  • Overreaching instead of repositioning
     
  • Working below weak or compromised anchors
     
  • Forgetting lanyard redundancy
     
  • Allowing rope creep into the cutting zone
     
  • Rushing setup to “save time”
     

Time saved by skipping setup is lost correcting mistakes.

 

Professional Climbing Standard

Professional climbing and work positioning:

  • Protect the climber
     
  • Protect the tree
     
  • Improve work quality
     
  • Reduce long-term injury risk
     
  • Allow precise pruning decisions
     

If your position does not feel controlled, it is not acceptable.

 

Professional Judgment & Pruning Accountability

Every climber is responsible not only for how a cut is made, but why it is made. Professional judgment separates trained arborists from laborers.

Before each cut, climbers should be able to clearly answer:

  • What problem does this cut solve?
     
  • Will this cut reduce future risk or defects?
     
  • Is this the smallest cut that achieves the goal?
     
  • Will this cut be defensible years from now?
     

Good pruning is intentional, conservative, and based on tree biology. Unnecessary cuts create unnecessary problems. When uncertainty exists, the correct action is to pause, reassess, and consult rather than proceed.

Professional arborists are judged by the long-term condition of the tree, not the speed of the work.

 

Long-Term Tree Health & Professional Standards

Trees respond to pruning over years and decades, not days. Every cut influences future structure, decay development, and maintenance needs.

Professional standards require that climbers:

  • Preserve branch collars and natural form
     
  • Minimize live tissue removal
     
  • Avoid creating large or unnecessary wounds
     
  • Protect trees from climbing-related damage
     
  • Prioritize structural integrity over appearance
     

Training does not end when the climb is complete. Continual observation, evaluation, and refinement of technique are essential to professional growth.

The goal of professional tree work is not simply to finish the job — it is to leave the tree safer, healthier, and better structured than before.
