Tree Risk Assessments: Level 1, 2, and 3
Have your trees grown to a size that makes you nervous for your safety? Tree risk assessments performed by certified arborists can help gauge the safety of a tree on your property with these three levels of detail:
- Level 1 – A limited visual assessment for when you have many trees and are not sure where to begin
- Level 2 – A basic assessment for when you can point out a tree with safety concerns
- Level 3 – An advanced risk assessment for when you know your trees are safety risks, but you want to keep them
Davey now uses sonic tomography technology for decay detection in trees. The tool utilizes sound waves to detect decay or cavities inside aboveground woody tree parts such as trunk and scaffold limbs.
The results of your tree assessment are typically provided in an arborist report suitable for permit applications in your municipality.
