On 2 June 2025, a woman jogging along the popular Thames Path near Barnes, south-west London, was struck by a falling tree. Emergency services were called to the scene at around 7:20 am. The runner received on-site treatment before being transported to hospital by the London Ambulance Service. The area was quickly cordoned off to remove the tree and assess any immediate dangers to the public.
This incident, although rare, has sparked renewed discussion on BBC news about the importance of tree inspections and risk management—especially in areas with high foot traffic. Whether trees are on public land, residential property, or near well-used paths, landowners have a legal and moral responsibility to ensure they are maintained safely.

Understanding Tree Hazards: What Went Wrong?
Falling trees and branches can pose a significant risk to life and property. While the circumstances surrounding the tree failure in Barnes are still being investigated, several key issues may have contributed:
- Structural weaknesses such as decay or disease
- Previous storm damage
- Poor tree maintenance or neglect
- Age-related failure in mature trees
Urban trees can face stress from compacted soil, pollution, limited rooting space, and construction activities. These conditions may not be immediately visible to the untrained eye, but they can significantly affect the health and stability of a tree.
How Often Do These Incidents Happen?
Despite media attention, falling trees rarely result in injury. According to the National Tree Safety Group (NTSG), the average annual risk of being killed by a tree in the UK is about 1 in 10 million. However, the low frequency does not eliminate the responsibility to manage these risks. A single incident can be catastrophic—not only for those involved, but also in terms of legal liability and public confidence.
Legal Responsibilities for Tree Owners
All tree owners—whether private individuals, local authorities, or corporate landowners—have a duty of care to the public. This is defined under various legislation, most notably the Occupiers’ Liability Acts 1957 and 1984 and the Health and Safety at Work etc. Act 1974 for organisations managing land accessible to employees or the public.
Failure to inspect and maintain trees can result in prosecution, insurance claims, or substantial financial penalties.
Key Legal Considerations
Trees must be inspected at intervals proportionate to their location and level of risk.
- Records of inspections and works carried out should be maintained
- Any high-risk trees near roads, footpaths, or public buildings should be prioritised
- Dead, dying, or dangerous trees must be managed promptly
Local authorities are increasingly aware of the legal implications of tree failure. Private landowners, however, may not realise their responsibilities extend to trees bordering roads or public paths.
The Role of Professional Tree Risk Assessments
A tree risk assessment is a professional service carried out by a qualified arboriculturist or tree surveyor. The goal is to assess the likelihood of failure and the potential consequences, and then recommend appropriate action.
What Does a Tree Risk Assessment Involve?
A comprehensive tree risk assessment generally includes:
- Visual inspection: Assessing the condition of the trunk, canopy, and root flare
- Diagnosis: Identifying pests, diseases, fungi, or decay
- Risk categorisation: Assigning a priority level based on severity and likelihood
- Recommendations: Advising on pruning, removal, bracing, or reinspection intervals
Many professionals now use tree risk software tools to document findings and standardise reporting, ensuring traceability in the event of a dispute or claim.
Who Needs a Tree Survey?
Tree risk assessments are especially important for:
- Landowners with trees near public highways, schools, parks, or transport routes
- Housing associations and property managers
- Local councils and parish authorities
- Large estates or commercial premises
In high-traffic zones, more frequent inspections—typically every 1 to 3 years—are advised. Trees in low-occupancy areas may be inspected less often, provided no change in condition is observed.
Preventing Incidents Through Proactive Tree Management
The Thames Path incident serves as a stark reminder that tree management is not simply about aesthetics or conservation—it’s about safety. Trees should be valued and preserved, but not at the expense of human life or wellbeing.

Tips for Responsible Tree Management
- Schedule regular inspections with a qualified arborist, especially for mature trees or those near roads and footpaths.
- Keep records of all assessments, works, and decisions made. This is crucial for demonstrating due diligence.
- Act quickly on high-risk findings. If a tree is deemed hazardous, arrange for remedial work without delay.
- Understand seasonal risks. Many structural failures happen in summer after heavy rain or during stormy periods when the canopy is full.
- Monitor tree health continually. Visual checks in between formal surveys can catch emerging issues early.
- Urban trees enhance biodiversity, reduce urban heat, and contribute to mental wellbeing. But poorly managed trees can turn from assets to liabilities.
Conclusion: Safety Must Be at the Root of Urban Tree Care
While falling tree incidents are statistically rare, they are not insignificant. The recent injury to a runner in Barnes has raised essential questions about public safety and the condition of our trees in shared spaces. Regular, professional tree risk assessments should be standard practice—not just in high-profile areas like the Thames Path, but anywhere trees interact with people.
Whether you are a homeowner, estate manager, or local authority, taking tree risk seriously is an investment in safety, liability protection, and public trust. Trees enrich our lives—but it is our duty to ensure they don’t endanger them.
