A tree risk assessment is a comprehensive investigation into the degree of risk that is posed by a single tree or multiple trees on a property. The assessment aims to identify just how likely a branch, or the entire tree is to fail and what the impacts of that failure are likely to be. The qualified arborist can then determine exactly which actions need to be taken to mitigate that risk.
Wherever there could be a potential threat to people or property, tree risk assessments can be carried out. These might include such locations as parks, playgrounds, schools and residential properties.
What is a Tree Risk Assessment?
Depending on the site and the number of trees being assessed, your qualified Arborist can assess and identify any trees that pose an immediate or potential risk of failure. A number of varied factors will be assessed by your qualified arborist to provide a complete and thorough arboricultural tree report of each tree’s health, structure and risk level.
Some of these factors are:
- The tree species
- Any signs of pest infestation
- Canopy density
- Any visual defects
- Structural integrity of trunk/s
- Amount of deadwood present
- Location of the tree and proximity to buildings or other structures
- Proximity to powerlines or other services
- Signs of wounds
- Frequency of people within the fall radius
Who can perform a Tree Risk Assessment?
Only an AQF Certificate 5 Arborist can carry out a tree risk assessment, as they have the qualifications, knowledge and experience to provide an accurate detailed assessment.
Ensure any arborist you hire to carry out an assessment can show evidence of holding a minimum AQFÂ Certificate 5 in Arboriculture.
