The close interaction between people and trees in urban areas poses specific challenges to the balance between managing risk and preserving the urban forest. Maya Tree is an experts in tree risk assessment and mitigation, and focus on maintaining trees on the landscape with minimal risk to the public, property and infrastructure. We are trained and equipped to apply advanced sonic tomography to non-invasively determine the internal structure and integrity of potential risk trees. This enables us to consistently present clear, defensible and accurate recommendations for risk mitigation, and empowers our clients with the knowledge to make truly informed decisions about their trees.
Visual risk assessment
Through this basic risk assessment methodology, Maya Tree certified arborist identify factors such as pests, diseases, site conditions and structural weaknesses which may contribute to elevated risk of whole tree failure or failure of component parts such as branches. This risk assessment methodology is the first step to identify hazard trees.
Sonic Tomographic is a method to detect decay and cavities in standing trees non-invasively. The velocity of sound waves in wood depends on the modulus of elasticity and the density of the wood itself. The unit tracks the speed of these waves. Most damage and disease causes fractures, cavities, or rot and reduces the wood’s elasticity and density.
Benefits of Sonic Tomography
Sonic tomography reveals the internal condition of a tree throughout a vast portion of the stem. By better understanding the structural integrity of a tree, you have a more accurate sense of the level of risk the tree represents, and can determine the best course of action to take.
Benefits for public and private tree management are significant. The information provided through sonic tomography allows you to:
- Prioritize trees based on risk level
- Avoid unnecessary felling of low risk trees
- Avoid accidents by removing high risk trees
- Save money by preventing unnecessary removal of trees
- Protect the equity trees add to an environment
An aerial inspection (crown inspection) is the inspection of the aboveground parts of a tree not visible from a ground-based inspection, including the upper trunk, upper surfaces of stems, and branches. Aerial inspections usually include a visual assessment for defects, conditions, and response growth. Conditions of particular importance include inspection of significant branch junctions, cracks in branches, sunscald on the tops of branches, and bark damage from bird or animal feeding. In addition, aerial inspections may include evaluation of internal decay. We perform our aerial inspection using our UAV (Drones).
