Tree Surveys for Commercial Sites: Identifying Dangerous Trees Before They Become a Liability

Trees are a valuable part of many commercial properties, providing shade, improving the appearance of outdoor spaces and making sites more welcoming for staff, customers and visitors. Regular tree surveys help keep them that way.

However, when trees are growing close to buildings, car parks, footpaths or busy public areas, their condition needs to be properly monitored.

For facilities managers, business owners and property management companies across Devon, professional tree surveys are an important part of maintaining a safe site and identifying potential problems before they become more serious.

At DTG Tree Consultancy, we carry out tree surveys and risk assessments throughout Devon, helping commercial clients understand the condition of their trees and make informed decisions about ongoing maintenance.

Why Commercial Properties Need Tree Surveys

Unlike a private garden, commercial sites often have a greater number of people moving around them throughout the day.

A mature tree next to a quiet boundary might present a very different level of risk compared with one overhanging a busy entrance, staff car park or children’s play area.

For businesses responsible for managing these spaces, knowing the condition of the trees is an important part of their wider duty of care.

A professional tree survey helps identify structural weaknesses, disease, decay and other concerns that might otherwise go unnoticed.

It also provides a clearer picture of what maintenance is actually necessary, helping property managers avoid both unnecessary expenditure and potentially dangerous delays.

The National Tree Safety Group’s guidance recommends a sensible, proportionate approach to tree risk management, balancing public safety with the considerable benefits that trees provide.

What Are the Warning Signs of a Potentially Dangerous Tree?

Not every unhealthy-looking tree is dangerous, and even healthy trees can occasionally lose branches. However, certain visible changes should prompt further investigation.

Some of the warning signs include:

• Dead or hanging branches: Particularly concerning when positioned above entrances, pathways or parking areas.
• Cracks or splits in the trunk: These can sometimes indicate structural weakness or movement within the tree.
• Fungal growth around the base: Certain fungi may be associated with decay affecting roots or lower stems.
• Sudden changes in leaning: A tree that has recently moved or developed lifting soil around its base may require urgent attention.
• Sparse or declining foliage: Unusual leaf loss or dying sections of the crown can indicate underlying problems.
• Storm damage: Strong winds can leave branches weakened or expose existing structural defects.

These signs do not automatically mean a tree needs removing. A professional inspection helps establish the seriousness of the issue and what action, if any, is appropriate.

If a tree appears immediately dangerous, access to the affected area should be restricted while professional advice is sought.

What Happens During a Commercial Tree Survey?

A commercial tree survey involves assessing relevant trees across a site and recording their condition, surroundings and any identifiable concerns.

At DTG Trees & Grounds, our inspections consider factors such as tree health, structural condition, visible defects and the potential consequences of tree or branch failure.

The assessment also considers how the surrounding area is used.

For example, a tree beside a frequently used footpath at a care home in Exeter may need a different management approach from one growing in a rarely accessed section of a rural estate near Dawlish.

Following the inspection, clients receive practical recommendations that may include:

• Crown reductions or selective pruning
• Removal of dead or damaged branches
• Further specialist investigation
• Monitoring and future inspections
• Tree removal where justified by the findings

This helps commercial clients better understand the level of risk rather than relying solely on subjective descriptions.

Managing Liability Through Planned Tree Inspections

One of the biggest advantages of professional tree surveys is having a documented approach to tree management.

If a tree-related incident occurs, property owners and managers may need to demonstrate that they took reasonable steps to identify and address foreseeable risks.

A survey report can provide a useful record of the trees inspected, their condition at the time and the recommendations made.

However, arranging a survey is only part of the process. Any necessary work should also be considered, prioritised and recorded.

There is no single inspection interval suitable for every commercial property. The frequency depends on the trees, their condition, the site environment and how frequently surrounding areas are used.

A well-managed programme allows businesses to prioritise work based on actual risks rather than waiting until something goes wrong.

Tree Surveys for Schools, Care Homes and Commercial Estates

Different commercial environments have different tree management requirements.

Schools and nurseries need particular consideration around playgrounds, entrances and outdoor learning areas, while care homes may have gardens and pathways used by residents with reduced mobility.

Holiday parks, business parks and managed residential developments also benefit from planned inspections, particularly where mature trees are located near accommodation, roads or communal spaces.

Across Devon, our team supports commercial clients in areas including Exeter, Dawlish, Teignmouth, Newton Abbot, Torquay and Paignton.

Tree inspections can also complement our commercial grounds maintenance services, helping site managers coordinate routine outdoor maintenance with specialist arboricultural work.

What If a Commercial Tree Is Protected?

Some trees on commercial land are protected by Tree Preservation Orders (TPOs) or conservation area legislation.

This can affect what work is permitted, even where a tree requires maintenance.

For example, Exeter City Council provides information on protected trees and Tree Preservation Orders, including how to check whether a tree is protected.

Similar considerations apply to commercial properties within Teignbridge and other Devon council areas.

Where protection applies, consent or prior notification may be necessary before carrying out work, subject to the relevant legal provisions and exemptions.

Our team can provide advice on tree work applications and help clients understand the appropriate next steps.

Why Choose DTG Trees & Grounds?

We are also proud to be an ARB Approved Contractor.

For commercial clients, our focus is on clear reporting, sensible recommendations and helping property managers make informed decisions about the trees they are responsible for.
