When it comes to planning construction projects or managing green spaces, one of the most essential steps often gets overlooked—tree surveys. A tree survey is an in-depth analysis of the trees on a property, evaluating their health, size, species, and overall condition. For property owners, developers, and anyone involved in land management, understanding tree surveys and their significance is key to ensuring compliance with local regulations, promoting sustainability, and maintaining the environment’s ecological balance.

What is a Tree Survey?

A tree survey is a comprehensive report carried out by a qualified arborist or ecologist. The survey typically includes:

• Species identification: Identifying the type of trees present on the property.
• Tree health assessment: Examining the health and structural condition of the trees.
• Size and age determination: Measuring the height, spread, and age of the trees.
• Protection recommendations: Offering advice on how to protect trees during development or construction.
• Root system evaluation: Assessing how the roots might interact with surrounding structures or underground utilities.

The purpose of a tree survey is to gather all this information to make informed decisions regarding tree management, planning permissions, and construction activities.

Why Are Tree Surveys Important?

1. Compliance with Planning Regulations: In many countries, there are strict regulations regarding tree preservation and management, particularly when the trees are within urban areas, conservation areas, or on development sites. A tree survey ensures compliance with these regulations, avoiding costly fines or delays in projects.

2. Environmental Impact Assessment: For developers, understanding the ecological value of the trees on their property is crucial. A tree survey can provide vital information on how the proposed development might impact the environment. In some cases, trees may need to be protected or preserved, while others might need to be removed to facilitate construction.

3. Sustainable Landscaping and Urban Planning: Proper tree management contributes to the sustainability of an area. Trees help absorb carbon dioxide, improve air quality, reduce urban heat islands, and provide habitats for wildlife. A tree survey helps incorporate green spaces into development plans while also promoting the preservation of existing trees.

4. Risk Management and Safety: Tree surveys help identify any hazardous trees that may pose a risk to nearby properties, roads, or pedestrians. This is particularly important for large trees with potential structural weaknesses that could lead to falling branches or whole trees during storms or other extreme weather conditions.

5. Increasing Property Value: Properties with well-maintained trees and green spaces tend to have higher market value. A tree survey helps property owners make the most of their landscape by identifying trees that can enhance the aesthetic and ecological value of the area.

What Does a Tree Survey Include?

A typical tree survey will include the following components:

• Tree Location: A map or plan showing the position of all significant trees.
• Tree Details: Detailed information about each tree, such as species, size (height, spread, trunk diameter), and age.
• Health and Condition: A thorough assessment of the tree’s health, identifying signs of disease, pests, or structural defects.
• Protection Measures: Recommendations on how to protect trees during construction, such as fencing or ground protection.
• Planning Implications: An analysis of how the trees may affect or be affected by any proposed development work, including the need for tree removals or replacements.

Types of Tree Surveys

1. Arboricultural Survey: This type of survey focuses on the health, safety, and management of trees. It includes the assessment of tree age, species, and condition to determine how the tree should be cared for.

2. Ecological Survey: This survey assesses the potential ecological value of the trees, particularly in relation to local wildlife habitats. It is often required when the property is located near protected areas or if wildlife may be affected.

3. Tree Preservation Order (TPO) Survey: If the trees are protected by a TPO, this survey assesses whether any work on the trees can be carried out legally, ensuring the preservation of valuable trees.

4. BS5837 Survey: This is a specific type of survey carried out for development sites. It assesses the trees within or near a development area to determine how the development will affect them and vice versa.

How to Get a Tree Survey

Tree surveys must be carried out by a qualified arborist or ecologist, as they require expert knowledge to assess tree health, safety, and ecological importance. Many surveyors will offer a full report with detailed recommendations, including how to preserve trees or what actions to take if trees need to be removed.

In the UK, professional services such as Gradwell Ecology’s Tree Surveys and Planning offer comprehensive assessments. These services help developers and property owners navigate the complexities of tree management, ensuring all legal and environmental responsibilities are met.

Conclusion

A tree survey is an invaluable tool for anyone involved in property development, land management, or even just maintaining a green space. By understanding the condition, value, and legal protections of trees on a property, stakeholders can make informed decisions that benefit the environment, the project, and the community as a whole. Whether you're a property owner, developer, or ecologist, a tree survey is an essential step in responsible tree management and sustainable development.
