Arborist Reports

​Arborist reports are valuable tools used to document tree health and any issues regarding its risk, site conditions, pest & disease, and structure.  Reports can vary from an oral report or letter, to a formal written report, depending on the needs of the client.

Reports typically include:
  • Tree species, size, and condition
  • Information regarding the cause of issues
  • Discussion of general health of tree
  • Relevant pest/disease issues
  • Structural integrity and condition of tree
  • Discussion of tree's risk
  • Recommendations as needed

Reports can include: 
Arborist reports are often a requirement prior to tree removal in many municipalities.

Tree Risk Assessments

A formal tree risk assessment is valuable for determining the risk that a tree poses to people or property and to prioritize tree work to reduce risk.  The assessment can include a written report describing the risk that your tree poses, as well as mitigation options to reduce this risk.  Merlin is an ISA Qualified Tree Risk Assessor (TRAQ) through the International Society of Arboriculture.  

​What is TRAQ?
(From the ISA): "The ISA Tree Risk Assessment Qualification (TRAQ) program provides an opportunity for professionals in the arboriculture industry to expand their knowledge through education and training in the fundamentals of tree risk assessment. This qualification promotes the safety of people and property by providing a standardized and systematic process for assessing tree risk. The results of a tree risk assessment can provide tree owners and risk managers with the information to make informed decisions to enhance tree benefits, health, and longevity."

Tree Appraisal

Trees provide many benefits and can be valuable assets to your property. Tree appraisal is used to help owners determine the value of their trees, including environmental, functional, aesthetic, and economic benefits.

Tree Management Plans

We work with clients to develop long and short term management plans for their trees and property sites.  

This includes:
  • Determining and prioritizing pruning needs
  • Cabling inspections
  • Soil fertility management
  • Safety monitoring

Construction Impact Monitoring and Mitigation

Damage to trees from construction can be irreparable.  We work with homeowners, contractors, and developers to set up protections for trees so they thrive long past the construction project.  We also work with clients to recommend which trees to preserve and steps to be taken to do so.

  • ​Calculate and implement tree protection zones (TPZ)
  • Onsite monitoring during construction projects
  • Work with contractors and designers during the planning phase to minimize impact to trees
  • Determine tree suitability for retention
  • Post-construction management ​​
