Workshop Descriptions

Advanced Tree Identification

This course is designed as a supplement and compliment to the Basic Tree Identification course. Where the basic course covered concepts and terminology of tree identification, this advanced identification workshop will expand upon those concepts and techniques, and cover individual species common to our area.  We will be going over identification characteristics of common trees in the region.

Basic Tree Appraisal

Focusing on the CTLA Trunk Formula Technique (TFT), this workshop gives an overview of the appraisal process and provides an opportunity to practice in the field. Participants will review common mistakes and refine their craft as appraising arborists.

Common Fungi Affecting PNW Trees and Implications for Tree Risk Assessment

This course will be of use to anyone interested in tree diseases, and particularly anyone conducting risk assessment of trees with disease.

Arborists and foresters conducting tree risk assessments need to:

  1. Know what to look for, and
  2. Know what they are looking at.

Fungi affecting trees show considerable variability in form and their ability to cause decay. Part of that variability is driven by the species of tree and fungus, the age and vigor of the tree, the extent of the fungal attack and associated decay, and the ability of the tree to compartmentalize the invading pathogens. Understanding the CODIT process is integral to understanding where decay may be within the tree. Minimizing bark scaring from park or forest management activities reduces the creation of fungal infection courts that threaten long-term tree health.

Effective Report Writing: Guidance for Arborists and Urban Foresters

Writing is a critical part of communication. If the reader cannot understand what you are telling them, how do you expect them to proceed?  In this class we will review how to write effectively. We will work on the writing styles needed to develop or respond to a request for proposal, as well as site memos, field reports, letter and formal reports with each one tailored to their intended use. The report themes will focus on risk assessment, construction sites, and site memos in general.

Fruit Tree Pruning

Arborists are often asked to prune fruit trees that have been long neglected or haphazardly pruned without a clear philosophy. This class will equip participants with knowledge specific to fruit trees: common trained forms and pruning approaches, species-specific habits and challenges, and tactics to improve production of quality fruit. We will discuss how to interpret and approach client expectations and needs while prioritizing biology-based care, and opportunities for educating and partnering with clients. The day will consist of an indoor lecture, outdoor tour/demonstration on a site with diverse trees, and light hands-on practice in groups.

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.

ISA Tree Risk Assessment Qualification Renewal

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. The Tree Risk Assessment Renewal workshop is a one-day refresher, with five hours of instruction, and three hours of take the exam. Current TRAQ holders can complete the abbreviated course as early as four years into their qualification.

Preserving Veteran Trees

These tree veterans will combine their diverse experiences to present a diverse and comprehensive perspective on preserving veteran trees. Each presenter will give a talk relating to their unique arena in the care of ancient trees. This seminar will cover;

  • How veteran trees function biologically,
  • How our views as an industry have changed over time regarding veteran tree care,
  • How our current industry standards apply to veteran tree care,
  • Case studies on how care of veteran trees is currently being performed in the field, and
  • How technologies can be utilized to preserve veteran trees.

This workshop will feature information on a large range of veteran tree species native to Northern California and Lowland Puget Sound. Tree care will be discussed in situations including residential sites to remnant forest trees in your neighborhood park. A wide range of tree risk mitigation options will be explored.

Report Writing for Arborists

Good communication is essential to every facet of arboriculture. Good reports, whether bids or cost proposals, management plans, risk assessments, or appraisals, are an effective communication tool that can ensure a positive outcome for any project.

This workshop provides simple, easy-to-understand instruction to support arborists in writing effective reports. Topics will include report-writing basics, the crucial elements of an effective report, and various report styles, from a simple on-site field reports and estimates to comprehensive booklet-style reports. Authored reports will be reviewed and critiqued, and report templates included in the take-home handouts.

Trees and Construction

This all day workshop will include information specific to arborists working around construction. The class is appropriate for Commercial Arborists, Consultants, and Professionals in related fields such as Architecture, Landscape Architecture or Planning. The workshop will be 75% indoors with lecture and group activities. We will go outdoors to look at tree preservation examples near the classroom.
