Arborist Tree Pruning Course

Lesson 1 • Tree Structure and Architecture

Examines crown form, branch attachment angles, and structural defects. Provides the visual assessment skills needed before any aerial entry.

Lesson 2 • Industry Terminology and Standards

Introduces standardized pruning terms and professional practice guidelines. Ensures consistent communication across crews and with clients.

Lesson 3 • Tree Biology Essentials

Covers vascular systems, cambium, and growth patterns critical to pruning decisions. Connects biological knowledge directly to cut placement and wound response.

Lesson 1 • Fall Protection Fundamentals

Introduces harness types, lanyards, and anchor principles specific to tree climbing. Establishes the fall-protection logic that underpins all climbing chapters.

Lesson 2 • Body and Limb Protection

Addresses chainsaw-protective clothing, gloves, and foot protection requirements. Links garment ratings to cut-risk levels encountered during aerial pruning.

Lesson 3 • Head and Eye Protection

Covers helmet standards, face shields, and eye protection selection for aerial pruning. Connects PPE choice to specific overhead debris and chainsaw hazards.

Lesson 1 • Drop Zone and Exclusion Zone Setup

Covers calculating drop zones, placing barriers, and controlling public access around the worksite. Directly reduces struck-by risk for ground workers and bystanders.

Lesson 2 • Emergency Response Planning

Covers first-aid readiness, emergency contact procedures, and evacuation routes for aerial incidents. Integrates rescue skills from the climbing chapter into a site-specific response plan.

Lesson 3 • Crew Communication and Briefing

Establishes pre-job briefing structure, role assignments, and real-time communication protocols. Ensures every crew member understands tasks, hazards, and emergency procedures.

Lesson 4 • Pre-Job Hazard Assessment

Teaches systematic site inspection for utility lines, ground conditions, and structural hazards. Produces a written hazard assessment as the foundation for all site safety decisions.

Lesson 1 • Stationary Rope Technique

Teaches the classic doubled-rope technique for ascending and positioning in the crown. Builds foundational movement skills before introducing advanced systems.

Lesson 2 • Rope and Hardware Fundamentals

Covers rope construction, ratings, and hardware components used in arborist climbing systems. Provides the material knowledge needed to select and inspect climbing gear.

Lesson 3 • Moving Rope and Single-Rope Techniques

Introduces single-rope technique and mechanical ascender systems for efficient vertical access. Expands the climber's toolkit for large trees and long ascents.

Lesson 1 • Chainsaw Mechanics and Selection

Covers engine components, bar lengths, and chain types suited to aerial pruning tasks. Connects equipment selection to the weight and maneuverability demands of climbing.

Lesson 2 • Pre-Operation Inspection and Maintenance

Teaches daily inspection routines, chain tensioning, and sharpening for aerial saws. Ensures students can maintain cutting performance and reduce kickback risk.

Lesson 3 • Cutting Techniques and Kickback Prevention

Covers bore cuts, plunge cuts, and limb-removal sequences specific to aerial pruning. Emphasizes kickback prevention as the primary safety discipline for aerial saw use.

Lesson 1 • Correct Cut Placement

Teaches collar cuts, reduction cuts, and heading cuts with precise anatomical reference points. Directly links cut placement to wound closure speed and decay prevention.

Lesson 2 • Pruning Dose and Crown Removal Limits

Establishes maximum live-crown removal thresholds and their physiological basis. Prevents over-pruning errors that compromise tree health and structural integrity.

Lesson 3 • Pruning Timing and Wound Response

Covers seasonal timing effects on wound closure, disease entry, and tree vigor. Enables students to schedule pruning for optimal biological outcomes.

Lesson 4 • Pruning Objectives and Crown Goals

Defines clearance, structural, hazard-reduction, and aesthetic pruning objectives. Aligns each objective with specific crown outcomes and client expectations.

Lesson 1 • Rigging System Components

Covers rigging ropes, blocks, friction devices, and anchor slings used in tree work. Provides the hardware knowledge base for all rigging configurations taught in this chapter.

Lesson 2 • Load Calculation and Rigging Physics

Introduces force multiplication, swing loading, and anchor load estimation for rigging. Enables students to select hardware with adequate working load limits.

Lesson 3 • Rigging Point Selection and Spar Assessment

Teaches evaluation of live and dead wood rigging points for structural adequacy. Connects spar and branch assessment to safe load limits before cuts are made.

Lesson 4 • Advanced Rigging Configurations

Addresses redirected rigging, portawrap systems, and multi-piece removal sequences. Prepares students for complex removals in confined or high-consequence zones.

Lesson 1 • Pruning Near Utilities and Structures

Covers minimum approach distances, insulating tools, and coordination with utility providers. Addresses the highest-consequence aerial pruning environment encountered in practice.

Lesson 2 • Tree Risk Assessment for Pruning

Applies structured risk assessment frameworks to prioritize pruning interventions. Connects defect identification and failure likelihood to pruning scope and urgency.

Lesson 3 • Large and Mature Tree Pruning

Addresses the unique biomechanical and access challenges of pruning large, mature trees. Builds strategies for minimizing structural stress while achieving pruning objectives.

Lesson 4 • Pruning Program Planning and Documentation

Teaches multi-year pruning cycle design, specification writing, and outcome documentation. Prepares students to manage pruning programs across urban forests or large properties.
