VALID and QTRA Tree Assessment

No matter whether you’re a government agency, local authority, landowner, or homeowner, you have a duty of care to manage the risk from your trees falling or dropping branches.

VALID and QTRA are two internationally recognised tools for tree risk management.

The VALID tree risk assessment method integrates legal standards with ISO 31000 risk management principles to evaluate the likelihood of failure, occupency and consequences.

The Quantified Tree Risk Assessment (QTRA) method applies established and accepted risk management principles to tree safety.

Callophrys Tree Consultancy is one of the few arboricultural consultancies in Scotland able to offer both Quantified Tree Risk Assessments and VALID tree risk assessments.
