Tree Risk Studies

We offer specialized services in tree risk assessments to ensure the safety of people, buildings, and public or private spaces. A healthy tree can have structural defects or internal problems that only a qualified professional can identify. Our assessments help prevent incidents, enable responsible decision-making, and reduce legal liabilities as an owner or manager.

How we work

We conduct risk evaluations following standardized international methodologies, such as VTA (Visual Tree Assessment, Mattheck & Breloer 1994) or QTRA (Quantified Tree Risk Assessment, Mike Elisson). Our certified arborists analyze, for example:

• The structural and mechanical condition of the tree

• Symptoms of disease, pests, or decay

• Exposure to strong winds or extreme conditions

• The environment (pathways, residences, infrastructure)

• Potential impact in case of failure

Each assessment includes a risk level classification and clear recommendations: ranging from simple maintenance actions to pruning, structural reinforcement, or, in extreme cases, removal.
