TRAQ Methodology

TRAQ, developed by the International Society of Arboriculture (ISA), is a qualitative approach ideal for detailed evaluations of individual trees. It focuses on assessing the likelihood of tree failure, the potential impact, and the consequences, providing a thorough understanding of any risks. This method is perfect for clients needing in-depth analysis to make informed decisions about tree management, maintenance, or removal.

QTRA Methodology

QTRA is a quantitative approach that calculates the probability of tree failure, target occupancy, and potential consequences. This method is particularly useful for large-scale assessments, where multiple trees must be evaluated and managed efficiently. QTRA helps prioritise actions based on calculated risk levels, making it an excellent choice for managing tree risks across more significant properties or complex sites.

Tailored Assessments

At ArborScan, we tailor our tree risk assessment services to your requirements, offering the flexibility to use either TRAQ or QTRA based on your specific situation.
