Tree Surveys - Frequently Asked Questions
What is a tree inspection survey?
Yes. If potential internal defects or other concerns are identified during an inspection, further specialist investigations may be recommended to better understand the issue and guide future management decisions.
What is a Visual Tree Assessment (VTA)?
What is a walk-over or “negative” tree survey?
A walk-over (sometimes called a “negative”) survey involves inspecting trees across a site and only recording those that require works or further attention. Trees that do not present any notable issues are not individually recorded within the survey report.
A tree inspection survey assesses the visible condition of a tree or group of trees to identify defects that could affect their safety. The aim is to manage risk responsibly while retaining trees wherever possible.
Visual Tree Assessment is an industry-recognised method of inspecting trees from ground level. It focuses on identifying visible signs that may indicate structural weakness, poor health, or an increased risk of failure.
Do tree surveys guarantee that a tree is safe?
No tree survey can guarantee that a tree is completely safe. Trees are living organisms that change over time and can be affected by weather, ground conditions, and external damage. Surveys provide a professional assessment at the time of inspection and proportionate recommendations for management.
How often should trees be inspected?
Inspection frequency depends on factors such as tree condition, location, and how often people or property are present nearby. Trees in higher-risk locations generally require more frequent inspections than those in low-use areas.
What is a BS5837 tree survey?
A BS5837 survey is undertaken to support planning and development. It records tree information in a standardised format so that trees can be considered properly during site design and construction.
What is the difference between a tree inspection survey and a BS5837 survey?
Tree inspection surveys focus on tree condition and safety as part of ongoing management.
BS5837 surveys focus on planning and development, helping designers and planners understand how trees may influence site layout and construction.
Will trees be tagged and mapped?
Where required, trees can be tagged for identification and their locations plotted on digital maps to assist with management, works, or construction planning.
