Tree safety and risk assessments


Managing tree risk is the responsibility of the owners and managers of the land on which the trees grow. They have a moral and legal responsibility for personal and public safety.


Overall risk to human safety is low.


Trees grow in many different areas, in different situations and with varying degrees of public access or human activity. Where it is appropriate to manage trees, management should seek to enhance their significance, ecosystem services, biodiversity and social benefits they provide, and to manage the undesirable impacts they have, such as damage to property and risk to human safety.


Why do risk assessments?


Risk assessments protect workers and comply with law. They should be conducted before any work starts that requires a risk assessment.


5 steps to a risk assessment:


  • Identify hazards

  • Decide who might be harmed and how

  • Evaluate risks and decide on control measures
  • Record findings and implement them

  • Review and update when necessary


Mortgage reports and subsidence


Often if there are trees on or adjacent to properties then mortgage / insurance companies will require an assessment of the implications for direct and indirect damage and any recommendations for tree work now and in the future.


Direct damage is where tree roots will grow into or under the walls or foundations of properties and affect their structural integrity.


Indirect damage is where tree (or shrub) roots obtain water from the soil under foundations, reducing its volume and potentially causing differential movement of the structure.


Mortgage tree survey – shows all the trees in relation to the property that may impact the property, what condition the trees are in are in and what remedial works are required to mitigate the risks and manage the trees.


Subsidence reports.


Trees are a key influence of subsidence and are the main cause of subsidence movement in the UK. What trees are of concern? A tree of full maturity with little potential for future growth that has not caused damage to a building in the past may be less of a risk compared to that of a tree growing vigorously and increasing in size.


Subsidence reports highlight specific trees of concern which are being investigated. The report makes it clear to all parties the role of the tree in the subsidence investigation.
