Advanced Tree Appraisal: Anchoring Appraisals with Multiple Methods

Most appraisal training is focused on a very narrow slice of the world of tree appraisal: the Trunk Formula Method. This course explores the plethora of other methods that can be used by tree appraisers.

The course begins with an explanation of the concept of anchoring and how to evaluate the reliability, accuracy, and precision of data points. It then gives an overview of all three approaches to appraisal: cost, market, and income. It dives in and explores methods of appraising partial loss, diminution of market value, percentage contribution, and net present value. Next, participants have an opportunity to reconcile the many possible methods as they are applied to a given assignment.

The last third of the class is a series of case studies that give participants the opportunity to practice applying the methods discussed in class and to then choose and defend their own final appraisal conclusion.

Advanced Tree Risk Assessment

Tree risk assessment is an area of urban forest management that has evolved rapidly in the past decade. We have moved from simple hazard tree assessment concepts into a more sophisticated understanding of risk in general. With the introduction of the ISA’s Best Management Practices document for Tree Risk Assessment, and the Tree Risk Assessment Qualification (TRAQ), several new approaches and guidelines have been introduced. Within the field of tree risk assessment there are many techniques and concepts to master; from basic principles through to sophisticated diagnostic techniques.

This course will focus on Level Three advanced tree risk assessment, but will also link this to Levels One and Two to show when Level Three may be required, and how to relate it to other work.

Advanced Tree Risk Assessment: Principles and Practices

Tree risk assessment is an area of urban forest management that has evolved rapidly in the past decade. We have moved from simple hazard tree assessment concepts into a more sophisticated understanding of risk in general. With the introduction of the ISA’s Best Management Practices document for Tree Risk Assessment, and the Tree Risk Assessment Qualification (TRAQ), several new approaches and guidelines have been introduced. Within the field of tree risk assessment there are many techniques and concepts to master; from basic principles through to sophisticated diagnostic techniques.

This course will focus on Level Three advanced tree risk assessment, but will also link this to Levels One and Two to show when Level Three may be required, and how to relate it to other work.

This course will be delivered by Dr. Julian Dunster, the designer of the original Certified Tree Risk Assessor credential (TRACE) and author of the new ISA Tree Risk Assessment manual for the TRAQ course. The course will be of interest to anyone practicing tree risk assessment, and especially arborists already holding the TreeRisk Assessment Qualification.

Creating Wildlife Habitat Trees

Class participants will have the opportunity to learn best practices regarding the safe retention of tree portions for habitat. Techniques like Coronet Pruning will be demonstrated. In addition, participants will learn how to create bird boxes using pre-existing cavities. Saws can also be utilized to create habitat; we’ll explore how to attract desired animals by specifying the size and location of wood holes.

 

As arborists, it is our job to evaluate trees and offer solutions to mitigate risks. Frequently, wildlife habitat exists in known tree risks (i.e., cavities, dead snags, or broken tops). In many cases, risks can be reduced and mitigated while retaining existing wildlife habitat or creating new wildlife habitat.

Not all trees need to be used as habitat trees, but in the right place they can make a substantial, positive difference to the community. Knowing regulatory laws and protected species is the arborist’s responsibility. The people taking care of trees must realize the value in preserving and creating habitats, so we can live more symbiotically in the world.

Documenting Evidence: Practical Guidance for Arborists

Arborists routinely examine trees for health and risk. The assignment may involve site review, or checking a tree before pruning or removing it. Perhaps it involves collecting data to report about appraisal of damage or trespass issues, or forensic investigations about injuries caused by falling trees. This course covers the professional practice of recognizing and understanding evidence, and learning how to effectively use it in reports. It applies to tree care companies and climbers, municipal, utility, and consulting arborists - anyone working with trees who may later need to explain what was done on any given day.

Electrical Hazard Awareness Training

Arborists need to be aware of potential electrical hazards in their work environment.  Tree care brings arborists in close contact with energized power lines and equipment that have the potential for serious injury and fatalities. This training is for tree care professionals who want to avoid deadly encounters and other negative consequences with electricity.  Keep your crew safe with electrical hazard awareness training.

ISA Tree Risk Assessment Qualification

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.
