Tree Risk Management

Tree owners have a legal duty of care obligation to ensure, in so far as is reasonably practicable, that their trees do not cause injury or damage to others.  

What is considered ‘reasonably practicable’ can vary widely, depending on your circumstances and that of your trees. Whether you are responsible for a single tree or an entire tree population, engaging an experienced tree expert will ensure you discharge your obligation appropriately and without unnecessary cost.

Additionally, engaging an expert and following their guidance shifts the burden of responsibility from you to your expert.

Planning & Development

Planning & Development

Trees are a material consideration in the UK planning system, some may even be a material constraint to development. Local Planning Authorities (LPA) have a statutory duty to consider the protection and planting of trees when granting permission for proposed developments.

When applying for planning permission, for a site with existing trees on or adjacent to it, the LPA will require your application to be accompanied by an Arboricultural Report to British Standard 5837:2012 which includes:

  • a tree survey and tree categorisation;
  • an Arboricultural Impact Assessment (AIA);
  • a Tree Protection Plan (TPP); and
  • Arboricultural Method Statements (AMS).
