Providing an expert opinion on all your tree care needs

Advanced Tree Health Assessment

Trees may present a safety risk to people and property. Most mature trees have structural defects that may fail.

  • What is the probability that defect may fail?

  • What is the risk to your property?

  • What are the management options to reduce unacceptable risk?

ATS provides basic tree health assessments as part of our Plant Health Care services. However, some trees may warrant more detailed evaluation, testing, analysis and reporting. These services may include excavation of the root zone for evaluation, soil testing, foliar testing or aerial lift sample collection and laboratory testing. The findings of these tests would be analyzed culminating in a report summarizing findings and management recommendations.

Tree Risk Assesment

TRA uses the industry standard in tree risk assessment; International Society of Arboriculture (ISA) Tree Risk Assessment methodology. Our ISA Tree Risk Qualified arborists will perform the systematic process of evaluating the tree from the roots to the top of the tree. The evaluation may include advanced assessment methods and tools such as root excavations, Resistograph drillings to detect decay and aerial lift inspections.

The result of the evaluation will be a document summarizing the findings, risk and management options to reduce the risk.

This aerial lift inspection included Resistograph drilling of a trunk cavity high in the tree to measure the extent of decay.

Tree Removal Permit Application Process

A number of communities in the Roaring Fork Valley require approval from the municipality to remove trees and plans to mitigate those removals. This process includes preparing an application, a report detailing the location and condition of the trees to be removed and if required a plan to mitigate the removal of the trees.

ATS will perform an inventory of the proposed tree removals; documenting the species, size, condition, the location of each tree the property and summarize the findings in a report. We will develop a mitigation plan if required or work with the design firm designated to work on your site improvement plan. We will complete and submit the municipal application and work to gain approval of a project that meets your and the municipality’s objectives.
