Introduction
Trees add beauty, structure, and biodiversity to outdoor spaces — but they also come with responsibility. Without proper care and attention, trees can become dangerous, posing risks to people, property, and surrounding vegetation. In many cases, tree-related accidents are preventable with early detection and intervention.
At LM Tree Surgery Winchester in Winchester, Hampshire, we often respond to emergencies that could have been avoided with timely inspection and maintenance. This guide will help you recognise common tree hazards before they escalate into serious problems, and explain how professional tree surgery can play a crucial role in prevention.
Understanding Tree Hazards and Their Causes
Tree hazards are often the result of unseen decay, poor structure, disease, or damage caused by weather or human activity. Identifying these risks early can protect your home, reduce liability, and extend the lifespan of your trees.
Common Causes of Tree Hazards
- Storm damage or lightning strikes
- Soil instability or root disturbance
- Fungal infections or pest infestations
- Improper past pruning
- Overcrowded or competing growth
- Construction or vehicle impact
Hazards aren’t always obvious, but with a trained eye and consistent monitoring, most warning signs are detectable before failure occurs.
Key Signs Your Tree May Be a Hazard
Structural Weakness
Trees with co-dominant stems — where two trunks grow from the same point — are particularly prone to splitting. Look for visible cracks or included bark at junctions where stems meet.
Dead or Dying Limbs
Deadwood is brittle and prone to breaking off unexpectedly. Branches without leaves during growing season, or those that snap easily, may need removal.
Leaning or Uprooting
A sudden lean or visible root lifting indicates instability. Trees that lean naturally may be fine, but a recent or worsening tilt is a serious warning.
Fungal Growth
Fungi such as bracket mushrooms at the base or on the trunk often indicate internal decay. While not all fungi are dangerous, they’re a sign that the tree should be assessed.
Cankers and Wounds
Areas of sunken or missing bark can expose the tree to pests and disease. These cankers may interrupt nutrient flow and weaken overall structure.
Additional Red Flags
- Excessive leaf drop out of season
- Discolouration or patchy foliage
- Cavities or hollowing in the trunk
- Bark peeling away in large strips
- Evidence of pest activity or boreholes
When to Involve a Professional Tree Surgeon
The Limits of DIY Inspections
While regular observation is helpful, a certified arborist can provide a much deeper level of assessment. At LM Tree Surgery Winchester, we offer expert evaluations across Winchester, Hampshire using advanced techniques to detect internal decay, assess root health, and evaluate canopy stability.
Risk Assessment and Management
Our team can recommend and carry out:
- Crown thinning – to reduce wind resistance and load on limbs
- Deadwood removal – to prevent falling branches
- Bracing or cabling – to support weak junctions
- Selective pruning – to restore balance and remove hazardous growth
- Tree removal – only when absolutely necessary and carried out safely
Seasonal Considerations and Planning
Why Timing Matters
Hazards can emerge or worsen with seasonal changes. Winter storms may expose weaknesses, while autumn leaf drop can reveal structural defects. Planning routine inspections at least twice a year — spring and autumn — ensures early intervention.
The Role of Weather Events
High winds, droughts, and prolonged rainfall all affect tree stability. After a severe weather event, inspect your trees for:
- Broken or hanging limbs
- Soil heaving or root exposure
- Bark splitting or trunk cracks
- Unusual leaning
The Legal and Safety Implications
Property owners have a legal duty of care to manage trees that may pose a risk to others. Ignoring signs of potential failure could result in liability for damages or injury. Prompt action with the support of professional tree surgeons helps maintain a safe environment while fulfilling your responsibilities.
Conclusion
Spotting tree hazards early is one of the most effective ways to protect your property and the people around it. Regular visual inspections, combined with periodic assessments from experienced professionals, can save lives, preserve mature trees, and prevent avoidable expenses.
