    SEG Awards Level 2 Award in Practical Environmental and Conservation Skills
    SEG Awards Level 1 Certificate in Practical Environmental and Conservation Skills

    Topic Overview

    The SEG Awards Level 2 Award in Practical Environmental and Conservation Skills introduces you to the hands-on techniques used to manage and protect natural habitats. You'll learn how to identify common UK species, carry out practical conservation tasks like hedge laying and pond creation, and understand the legal frameworks that safeguard our environment. This qualification is ideal if you're considering a career in countryside management, horticulture, or environmental science, as it builds the foundational skills needed for further study or entry-level roles.

    The course covers five key areas: understanding environmental and conservation principles, carrying out practical habitat management, using tools and equipment safely, monitoring wildlife, and working effectively in a team. You'll spend time outdoors applying these skills, from coppicing woodland to constructing bird boxes. By the end, you'll be able to contribute to real conservation projects and appreciate how human activities impact ecosystems.

    This award sits within the wider SEG Awards Occupational Qualification suite, which focuses on vocational learning. It's designed to be accessible for students aged 14+ and provides a stepping stone to Level 3 qualifications or apprenticeships. The practical nature of the course means you'll develop transferable skills like problem-solving, communication, and environmental awareness, which are highly valued by employers in the green sector.

    Key Concepts

    Core ideas you must understand for this topic

    • →Biodiversity: The variety of life in a habitat; conservation aims to maintain or increase biodiversity by protecting species and their ecosystems.
    • →Habitat management techniques: Methods like coppicing, hedge laying, and pond creation that mimic natural processes to support wildlife.
    • →Health and safety: Risk assessments, correct use of tools (e.g., loppers, bow saws), and personal protective equipment (PPE) are essential for safe fieldwork.
    • →Species identification: Knowing common UK flora and fauna (e.g., oak, blue tit, stag beetle) using field guides and keys.
    • →Legal frameworks: Wildlife and Countryside Act 1981, Countryside and Rights of Way Act 2000, and Environmental Protection Act 1990 govern conservation activities.

    Learning Objectives

    What you need to know and understand

    • Be able to prepare foundations, Be able to construct a wall
    • Be able to prepare foundations, Be able to construct a wall

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for accurately setting out the wall line and excavating a foundation trench to firm, undisturbed subsoil, ensuring removal of all topsoil and organic matter.
    • Award credit for preparing a level and compacted foundation base, placing the largest, most stable stones as footing stones with their long axis running into the wall.
    • Award credit for constructing the wall with correct batter (taper) on both faces, typically a ratio of 1:6 to 1:8, maintaining consistent face alignment.
    • Award credit for building in horizontal courses, carefully selecting and bedding each stone with the grain laid horizontally, using sufficient hearting (small packing stones) to fill voids and bind the structure.
    • Award credit for incorporating through-stones (tie stones) at regular intervals, projecting a minimum of 150mm on each face to bond the wall together.
    • Award credit for finishing the wall with a secure coping, using selected flat or vertical stones firmly wedged and overlapping the top course.
    • Award credit for demonstrating correct measurement and excavation of foundation trench to specified dimensions (width, depth) and ensuring base is level and free of loose material.
    • Credit for selecting and placing appropriate foundation stones (larger, flat stones) and checking for stability before progressing.
    • Credit for constructing wall with proper batter (inward slope) and appropriate use of through stones to tie both faces, demonstrating structural integrity.
    • Evidence of correct coursing: stones selected and placed with tight joints, hearting material used to fill voids, and regular checking with spirit level and plumb line.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always inspect and sort your stone pile before starting; categorise by size and shape to speed up construction and improve stone selection.
    • 💡During assessment, regularly check the wall's line, level, and batter using string lines, spirit levels, and batter frames to demonstrate precision and quality control.
    • 💡Health and safety is critical—wear appropriate PPE (gloves, steel-toe boots) and use correct lifting techniques; a safety observation could be part of the assessment.
    • 💡Conservation context matters: where possible, use locally sourced stone and traditional techniques to match existing structures, showing awareness of environmental and heritage considerations.
    • 💡Always double-check foundation layout and dimensions against your assessment brief before placing stones, and photograph your work for your portfolio.
    • 💡Take time to sort and grade your stones by size and shape before starting construction, and keep your work area organized to improve efficiency.
    • 💡Demonstrate continuous evaluation by using a spirit level and string line at every stage, and make adjustments immediately before securing stones.
    • 💡In your reflective account or viva, explain your choices (e.g., why a particular stone was used as a through stone) to show deeper understanding of structural principles.
    • 💡In practical assessments, always explain why you're doing each step. For example, when planting a hedge, state that you're mixing native species to provide food and shelter for wildlife.
    • 💡Use correct terminology in written answers. Instead of 'cutting trees', say 'coppicing to promote regrowth and create varied age structure'.
    • 💡Link your actions to legislation. Mentioning the Wildlife and Countryside Act when handling protected species shows deeper understanding.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to remove all topsoil and organic material before laying the foundation, leading to settlement and wall collapse.
    • Placing stones with the grain running vertically (on bed), causing them to split under load or through freeze-thaw action.
    • Forgetting to batter the wall—building vertical faces that are structurally unstable and contrary to traditional dry stone walling principles.
    • Using insufficient through-stones or placing them incorrectly, resulting in a wall that lacks lateral strength and is prone to bulging.
    • Neglecting to use hearting, leaving large voids between face stones that compromise the wall's integrity and encourage water ingress.
    • Inadequate foundation preparation: trench not dug deep enough, not level, or containing organic matter, leading to wall movement later.
    • Ignoring the need for through stones or bonding stones, resulting in a wall that lacks lateral strength and may bulge over time.
    • Poor stone selection and placement: using rounded stones, not packing voids, or creating running joints (vertical joints aligned) which weakens the wall.
    • Failing to maintain consistent batter throughout the build, causing irregular face alignment and potential instability.
    • Misconception: Conservation means leaving nature completely alone. Correction: Active management like cutting back invasive species or coppicing is often needed to maintain biodiversity.
    • Misconception: All tools are safe if used carefully. Correction: Each tool has specific safety rules; for example, a bow saw requires a firm grip and proper stance to avoid kickback.
    • Misconception: You can identify any species by colour alone. Correction: Many species look similar; use multiple features like leaf shape, habitat, and behaviour for accurate ID.
