    Lantra Awards Level 3 Award in Felling and Processing Trees over 380mm and up to 760mm

    Topic Overview

    The Lantra Awards Level 3 Award in Felling and Processing Trees over 380mm and up to 760mm is an advanced qualification for experienced forestry and arboriculture professionals. It focuses on the safe and efficient felling of large-diameter trees, typically those found in mature woodland, parkland, or urban environments where precise directional felling is critical. This unit builds on foundational chainsaw skills, requiring candidates to demonstrate competence in assessing tree condition, planning escape routes, and using advanced cutting techniques such as the open-faced notch and bore cutting to control the tree's fall. Mastery of these skills is essential for reducing risk to the operator, the public, and surrounding property, and for maximising timber recovery.

    This qualification is part of the Lantra Awards suite of vocational qualifications in land management, which are widely recognised across the UK forestry and arboriculture industries. It is typically taken by individuals who already hold the Level 2 Award in Felling and Processing Trees up to 380mm, as it requires a higher level of technical knowledge and physical skill. The course covers risk assessment, environmental considerations (such as protected species and ground conditions), and the use of appropriate personal protective equipment (PPE). Successful completion demonstrates that the candidate can work independently to industry standards, making them more employable in roles such as forestry contractor, tree surgeon, or estate worker.

    Understanding how to fell and process large trees is not just about technique; it's about decision-making under pressure. Candidates must learn to evaluate factors like wind direction, tree lean, decay, and the presence of obstacles before making the first cut. The processing element involves cross-cutting and snedding (removing branches) to produce timber of specified lengths, often for firewood, fencing, or construction. This qualification ensures that operators can carry out these tasks safely, efficiently, and in compliance with current legislation, including the Health and Safety at Work Act and the Provision and Use of Work Equipment Regulations (PUWER).

    Key Concepts

    Core ideas you must understand for this topic

    • Advanced notch types: The open-faced notch (70° angle) and the conventional notch (45° angle) are used for large-diameter trees to provide greater control and hinge wood strength. The choice depends on tree lean, wind, and desired felling direction.
    • Bore cutting technique: Used to create a hinge without cutting through the tree's centre, reducing the risk of barber chair (splitting) and allowing precise directional control. The bore cut is made from the side, leaving a holding wood at the back.
    • Hinge wood management: The hinge (uncut wood between the notch and back cut) must be of consistent thickness (typically 10% of tree diameter) to guide the tree's fall. Incorrect hinge thickness can cause the tree to twist or fall off-line.
    • Escape routes and retreat paths: Before felling, two escape routes at 45° angles away from the expected fall direction must be planned and cleared. The operator must retreat along these routes immediately after the back cut is complete.
    • Risk assessment for large trees: Factors such as decay (e.g., fungal brackets, cavities), lean, wind loading, and nearby structures must be assessed. A dynamic risk assessment is performed throughout the operation.

    Learning Objectives

    What you need to know and understand

    • Evaluate the implications of health and safety legislation on felling operations for large diameter trees.
    • Identify and assess hazards specific to felling trees between 380mm and 760mm, implementing appropriate control measures.
    • Prepare a worksite for felling operations, ensuring safe access, egress, and escape routes.
    • Demonstrate precise felling cuts on trees 380mm–760mm in diameter using approved techniques to control direction of fall.
    • Apply methods to safely resolve hung-up trees, selecting and using appropriate tools and winching equipment.
    • Process felled timber efficiently, converting it into required sizes while maintaining chainsaw safety and productivity.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for thorough documentation of risk assessments, including identification of overhead hazards, ground conditions, and proximity to utilities.
    • Require demonstration of correct felling cuts with accurate gob cut depth and hinge wood thickness, ensuring controlled direction of fall.
    • Check for effective use of a felling lever or wedge to assist the fall and prevent bar pinch.
    • Assess safe takedown of hung-up trees using a winch or hand-powered device, ensuring no one enters the danger zone.
    • Evaluate the processing of timber: correct cross-cutting without chain contact with ground, and proper stacking of products.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always reference current Lantra guidance and the latest edition of the appropriate chainsaw operations manual in your risk assessments.
    • 💡Practice felling cuts on simulators or in a controlled environment before performing the assessed task to build confidence and precision.
    • 💡During the practical assessment, verbalize your actions as you perform them to demonstrate understanding of each step.
    • 💡Prepare a detailed site plan in your portfolio, noting environmental considerations and wildlife habitats to show full compliance with sustainable practices.
    • 💡During the practical assessment, examiners look for a systematic approach: start with a thorough site and tree assessment, clearly communicate your plan, and demonstrate smooth, controlled cutting. Rushing or skipping steps loses marks.
    • 💡Pay close attention to your hinge wood thickness. Use a tape measure or your saw's bar length as a guide. A hinge that is too thick can cause the tree to hang up; too thin and it may snap, causing a dangerous uncontrolled fall.
    • 💡Always maintain a stable stance with your feet shoulder-width apart, and keep the chainsaw close to your body for control. Examiners note your body positioning and saw handling throughout the felling process.

    Common Mistakes

    Common errors to avoid in your coursework

    • Incorrectly estimating the tree's lean and weight distribution, leading to unpredictable felling direction.
    • Neglecting to establish and maintain clear escape routes, resulting in being in the danger zone during the fall.
    • Using an inadequate hinge wood thickness, causing loss of control or barber chair.
    • Attempting to fell a hung-up tree by cutting the supporting tree without mechanical assistance, increasing risk of sudden release.
    • Misconception: A larger notch always gives better control. Correction: The notch angle and depth must be matched to the tree's diameter and lean. An overly deep notch can weaken the hinge, causing the tree to fall prematurely or off-target.
    • Misconception: Bore cutting is only for trees with a backward lean. Correction: Bore cutting is also used for trees with side lean or in windy conditions to maintain hinge integrity and prevent splitting. It is a versatile technique for any tree over 380mm.
    • Misconception: The back cut should be level with the notch apex. Correction: The back cut should be slightly above (2-3 cm) the notch apex to create a step that prevents the tree from sliding back off the stump. This is critical for safety.

    Frequently Asked Questions

    Common questions students ask about this topic

    Before You Start

    Prior knowledge that will help with this topic

    • Lantra Awards Level 2 Award in Felling and Processing Trees up to 380mm (or equivalent) – this ensures basic chainsaw operation and felling techniques are already mastered.
    • Understanding of tree biology and decay indicators – knowledge of how fungal decay, cavities, and cracks affect tree stability is essential for risk assessment.
    • Competence in chainsaw maintenance and sharpening – a poorly maintained saw is dangerous and inefficient; examiners expect candidates to check chain tension, sharpness, and oil levels before starting.
