Tree inspections and statute and common law applied to trees
This subtopic equips learners with the competence to conduct systematic visual tree inspections, identify structural defects, pests, and diseases, and determine the appropriate management recommendations. It integrates an understanding of common law duties, particularly occupiers’ liability and negligence, with statutory controls such as Tree Preservation Orders and felling licences to ensure legal compliance in arboricultural practice.

Quick Revision Summary (Key Takeaway)
The SEG Awards ABC Level 2 Certificate in Arboriculture covers the fundamental principles of tree care, including tree biology, identification, planting, pruning, and health assessment. This qualification equips students with the practical skills and knowledge needed to work safely and effectively in arboriculture, preparing them for roles such as groundsman or arboricultural assistant.
Topic Overview
Arboriculture is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants. The SEG Awards ABC Level 2 Certificate in Arboriculture provides a solid foundation in the science and practice of tree care, covering everything from tree biology and identification to planting, pruning, and safety. This qualification is ideal for those starting a career in the arboricultural industry, as it combines theoretical knowledge with practical skills.
The course is structured around key areas such as tree biology, soil science, tree identification, and practical techniques like pruning and planting. Students learn how trees function, how to assess their health, and how to carry out maintenance work to a professional standard. Safety is a major focus, with emphasis on risk assessment, personal protective equipment (PPE), and working at height.
This certificate is part of the Horticulture & Land Management suite of qualifications and is recognised by employers across the UK. It prepares students for further study, such as the Level 3 Diploma in Arboriculture, or for entry-level positions as arboricultural groundsmen or tree surgeons' assistants. The skills gained are essential for maintaining healthy, safe, and attractive trees in urban and rural environments.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a structured inspection method, such as Visual Tree Assessment (VTA), clearly recording observations of crown, stem, and root zone.
- Award credit for correctly identifying and categorising hazards (e.g., deadwood, cavities, fungal brackets) and linking them to appropriate risk-based recommendations.
- Award credit for accurately referencing relevant legislation (e.g., Highways Act 1980, Wildlife and Countryside Act 1981) and explaining its impact on tree work decisions.
- Award credit for evidencing understanding of common law principles by discussing duty of care, foreseeability, and the ‘reasonable person’ test in tree inspection scenarios.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always structure tree inspection answers around a logical sequence: site assessment, tree biology, hazard identification, and legal context.
- 💡Memorise the key pieces of legislation by name and year, and practise applying them to realistic scenarios to demonstrate practical understanding.
- 💡When recommending works, justify your choice by explicitly linking the inspection findings to the legal duty of care and the level of risk.
- 💡Always use correct arboricultural terminology, such as 'included bark', 'crown dieback', and 'root plate', to show depth of knowledge.
- 💡When answering questions about pruning, refer to the British Standard BS 3998:2010 and explain the reason behind each cut.
- 💡In practical assessments, demonstrate safe working practices at all times, including wearing appropriate PPE and using correct manual handling techniques.
Common Mistakes
Common errors to avoid in your coursework
- Confusing statutory legislation (e.g., Tree Preservation Orders) with common law duties, or applying one where the other is legally required.
- Relying on a single indicator (e.g., fungal growth) to condemn a tree without cross-referencing other signs or considering target value.
- Failing to consider the legal implications of tree ownership and boundaries, leading to incorrect advice about pruning overhanging branches.
- Overlooking the importance of recording inspection findings in a dated, signed report that would withstand legal scrutiny.
- Misconception: Topping a tree is an acceptable way to reduce its height. Correction: Topping is harmful and creates weak regrowth; proper crown reduction cuts back to lateral branches.
- Misconception: All trees have taproots. Correction: Many trees have fibrous root systems that spread widely; taproots are common in some species but not all.
- Misconception: Pruning in autumn is always best. Correction: Pruning timing depends on species and purpose; for many trees, late winter or early spring is better to avoid disease.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on tree biology and physiology. Revise the functions of roots, stems, and leaves, and create diagrams to label parts.
- 2Week 2: Learn tree identification. Collect leaf samples or use online resources to practice identifying 10 common species, noting key features.
- 3Week 3: Study pruning techniques and safety. Watch videos of proper pruning cuts and practice on model branches if possible.
- 4Week 4: Review tree health and risk assessment. Learn common diseases and defects, and practice completing a basic tree inspection form.
- 5Week 5: Attempt past exam questions and use active recall to test your knowledge. Focus on command words like 'describe' and 'explain'.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions: Test recall of facts such as tree species, parts of a tree, or safety equipment. Read each question carefully and eliminate obviously wrong answers.
- 📋Short-answer questions: Require a brief definition or explanation, e.g., 'What is included bark?' Give a clear, concise answer with an example if possible.
- 📋Scenario-based questions: Present a situation (e.g., a tree with decay) and ask for recommendations. Use your knowledge of tree biology and safety to give a reasoned response.
- 📋Practical assessments: You may be asked to demonstrate a skill like pruning or planting. Follow the steps in order and explain what you are doing to the assessor.
Command Word Expectations (SEG AWARDS)
What examiners look for when using specific command words in this specification
Give a detailed account of a topic, including key features and characteristics. For example, 'Describe the structure of a tree root' – you should mention the main parts (e.g., root hairs, cortex, xylem) and their functions.
Give reasons or causes for something, showing understanding of processes. For example, 'Explain why trees need to be pruned' – you should discuss health, safety, aesthetics, and growth control.
Weigh up the pros and cons of a situation and come to a judgement. For example, 'Evaluate the use of chemical weed control in tree planting' – discuss benefits (e.g., reduced competition) and drawbacks (e.g., environmental impact), then give a balanced conclusion.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A tree has a height of 12 metres and a crown spread of 8 metres. Calculate the tree's crown spread to height ratio and comment on its stability.
- 1.Step 1: Identify the given values: height = 12 m, crown spread = 8 m.
- 2.Step 2: Calculate the ratio: crown spread ÷ height = 8 ÷ 12 = 0.67 (or 2:3).
- 3.Step 3: Interpret the ratio: A ratio of 0.67 indicates the crown is relatively narrow compared to height, which may suggest good stability in exposed sites, but could also indicate competition for light.
- 4.Step 4: State the final answer with units: The crown spread to height ratio is 0.67:1.
Question: Describe the process of photosynthesis and explain why it is essential for tree growth.
- 1.Step 1: State the equation: carbon dioxide + water → glucose + oxygen (in the presence of light and chlorophyll).
- 2.Step 2: Explain the role of chlorophyll in capturing light energy.
- 3.Step 3: Describe how glucose is used: for respiration, growth, and storage as starch.
- 4.Step 4: Link to tree growth: photosynthesis produces the carbohydrates needed for cell division and elongation, forming new wood and leaves.
- 5.Step 5: Conclude with the importance: without photosynthesis, trees cannot produce energy or biomass, so they would die.
