Topic Overview
The City & Guilds Level 2 Diploma in Forestry and Arboriculture is a vocational qualification that equips learners with the fundamental knowledge and practical skills required for working in the arboriculture and forestry industries. The course covers a wide range of topics, including tree biology, identification, planting, pruning, and the safe operation of machinery such as chainsaws and woodchippers. It also emphasizes the importance of health and safety regulations, environmental sustainability, and the legal framework surrounding tree work.
This qualification is designed for individuals who wish to pursue a career as an arborist, forestry worker, or grounds maintenance operative. It provides a solid foundation for further study, such as the Level 3 Diploma in Arboriculture, and is highly valued by employers in the sector. The practical nature of the course means that students spend significant time outdoors, developing hands-on skills that are directly applicable to the workplace.

Assessment Guidance
Guidance for achieving higher grades
- 💡Always refer to the manufacturer’s operator manual during both preparation and maintenance assessments.
- 💡During practical assessments, talk through your actions to demonstrate your understanding of why each step is performed.
- 💡Practice systematic pre-use checks until they become automatic; use a checklist if permitted to ensure nothing is missed.
- 💡Familiarize yourself with common fault symptoms and corrective actions, as these are frequently assessed in oral questioning.
- 💡When operating, constantly assess your surroundings and be prepared to stop safely if conditions change.
- 💡For written components, use specific terminology from legislation and industry guidance to show technical knowledge.
- 💡Always use the correct technical terminology in your answers, such as 'hinge', 'sink cut', 'crown reduction', and 'PPE'. This shows the examiner that you have a deep understanding of the subject.
- 💡When answering questions about legislation, quote the specific act or regulation and explain how it applies to the scenario. For example, mention the Health and Safety at Work Act 1974 and the duty of care to employees and the public.
- 💡For practical questions, structure your answer in a logical sequence, step by step. This makes it easier for the examiner to follow and ensures you cover all necessary points.
Common Mistakes
Common errors to avoid in your coursework
- Skipping or rushing pre-use inspections, assuming the machine is in the same condition as last use.
- Failing to adjust seat, mirrors, and controls for individual operator ergonomics before startup.
- Operating machinery on slopes without understanding the machine’s stability limits and roll-over risks.
- Using incorrect fuel mix ratio or contaminated fuel, leading to engine damage or poor performance.
- Neglecting to check emergency stop mechanisms or not knowing how to activate them quickly.
- Not reporting minor faults or unusual noises, allowing small issues to develop into major failures.
- Misconception: 'Topping a tree is an acceptable way to reduce its height.' Correction: Topping is harmful and can lead to decay, weak regrowth, and tree death. Proper pruning methods like crown reduction should be used instead.
- Misconception: 'All trees can be felled in any direction.' Correction: The direction of fall is determined by the tree's natural lean, wind direction, and the presence of obstacles. A proper assessment is essential to ensure safety.
- Misconception: 'PPE is optional if you are experienced.' Correction: PPE is a legal requirement and should always be worn when operating machinery or working at height, regardless of experience level.
Revision Plan

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A tree surgeon needs to mix a 5% solution of glyphosate herbicide. They have a 10-litre knapsack sprayer. How much glyphosate concentrate (in millilitres) is needed?
- 1.Step 1: Identify the required concentration: 5% means 5 ml of concentrate per 100 ml of water.
- 2.Step 2: Calculate the total volume needed: 10 litres = 10,000 ml.
- 3.Step 3: Use the formula: (concentration % / 100) × total volume = amount of concentrate. So (5/100) × 10,000 = 500 ml.
- 4.Step 4: State the final answer with units: 500 ml of glyphosate concentrate.
Question: Describe the steps you would take to safely fell a small tree (e.g., 20 cm diameter) using a chainsaw, including the direction of fall and escape route.
- 1.Step 1: Assess the tree and surroundings: check for hazards such as dead branches, power lines, and obstacles. Determine the natural lean and decide the felling direction.
- 2.Step 2: Clear the work area: remove any undergrowth and ensure an escape route is clear at 45 degrees behind the tree.
- 3.Step 3: Make the felling cut: use a chainsaw to make a horizontal cut (the 'sink cut') on the side facing the felling direction, about one-third of the tree's diameter deep.
- 4.Step 4: Make the back cut: on the opposite side, slightly above the sink cut, leaving a hinge of wood to guide the fall.
- 5.Step 5: As the tree starts to fall, retreat along the escape route, keeping an eye on the tree and the surrounding area.
- 6.Step 6: After the tree is down, assess the area and proceed with limbing and cross-cutting as needed.
