Construction projects can pose significant risks to the health and stability of trees on your property. Whether you’re building an extension, installing new landscaping, or undertaking major structural work, protecting existing trees is essential to preserving your property’s natural beauty and ecological value. At NS Tree Surgery Godalming, we specialise in safeguarding trees during construction, ensuring that they thrive even in challenging conditions. In this article, we’ll explore the best practices for protecting your trees during construction projects and how to ensure their long-term health.
Why Tree Protection Is Important During Construction
Trees are more sensitive to changes in their environment than many people realise. Construction work can cause damage to roots, trunks, and branches, which may not be immediately visible but can have long-term effects on a tree’s health.
Common risks include:
- Root Damage: Digging, trenching, or soil compaction can damage or sever roots, leading to instability and reduced access to water and nutrients.
- Soil Compaction: Heavy machinery can compact soil around a tree’s base, restricting the flow of water, air, and nutrients to the roots.
- Physical Injury: Equipment, tools, and materials can damage the trunk or branches, making the tree susceptible to diseases and pests.
By taking proactive measures to protect trees during construction, property owners can ensure that their trees remain healthy and continue to provide value to the landscape.
1. Establish a Tree Protection Zone
One of the most effective ways to protect trees during construction is to establish a Tree Protection Zone (TPZ). This is a designated area around the tree that should remain free from any construction activity.
How to establish a TPZ:
- Calculate the TPZ Radius: The TPZ should be at least 12 times the diameter of the tree’s trunk. For example, if a tree has a diameter of 0.5 metres, the TPZ should extend at least 6 metres from the trunk.
- Install Barriers: Use sturdy fencing to clearly mark the TPZ, keeping machinery, workers, and materials out of this area. Signs indicating the importance of the zone can help ensure adherence.
- No-Go Area: Within the TPZ, avoid any soil compaction, storage of materials, or changes to soil levels. This will protect the root zone and prevent damage from heavy equipment.
2. Plan Construction Activities Carefully
Careful planning is crucial when construction takes place near trees. Consult with a qualified tree surgeon before beginning your project to determine the best course of action.
Consider the following during planning:
- Tree Survey: A survey can assess which trees are most vulnerable and provide guidance on how to protect them during construction.
- Route Machinery Wisely: Plan routes for machinery and vehicles away from sensitive tree areas to minimise the risk of root damage and soil compaction.
- Avoid Cutting Roots: If digging near trees is necessary, use hand tools rather than heavy machinery to avoid cutting through critical roots.
At NS Tree Surgery Godalming, we offer professional advice and assistance with tree surveys and planning to ensure your trees remain protected throughout your project.
3. Use Protective Wrapping for Trunks
Trees that are close to construction zones are at risk of damage from equipment or falling materials. Wrapping the trunks with protective material can help to minimise the risk of physical injury.
Best practices for protective wrapping:
- Use Padding: Wrap the tree trunk with hessian or other padding materials to provide a cushion against impact.
- Secure with Boards: Place wooden boards around the trunk for added protection, ensuring they are fastened without damaging the bark.
- Monitor the Wrapping: Inspect the wrapping regularly during the project to ensure it remains intact and adjust as necessary.
This simple but effective method can prevent damage that could otherwise compromise the tree’s health.
4. Monitor Tree Health During and After Construction
The effects of construction-related damage may not be immediately apparent, making it important to monitor trees for signs of stress during and after the project.
Signs of stress to look for:
- Wilting or Yellowing Leaves: This can indicate that the tree is struggling to absorb water due to root damage.
- Reduced Growth: A lack of new growth or smaller leaves may signal that the tree is under stress.
- Cracks or Fissures: Any physical damage to the trunk or major branches should be addressed promptly to prevent decay.
Regular inspections by a professional tree surgeon can help identify any emerging issues and provide treatments such as mulching, watering, or pruning to support the tree’s recovery.
5. Incorporate Tree-Friendly Practices
During construction, simple adjustments can make a big difference in protecting the trees on your property. Consider these tree-friendly practices:
- Mulch the Root Zone: A layer of organic mulch can help retain moisture and improve soil structure, providing vital support to the tree’s roots.
- Watering During Dry Periods: If the construction project coincides with dry weather, ensure that trees receive adequate water to prevent stress.
- Avoid Grade Changes: Altering the soil level around a tree can damage roots and affect its stability. If grade changes are necessary, consult a tree expert for guidance.
