In-Person Location: Mount Baker Rowing and Sailing Center, 3800 Lake Washington Blvd S, Seattle, WA 98118
Online Location: This workshop is available for remote attendance online. Gather a group at work and watch together. Every person taking the online workshop will need to register to receive CEUs.
Dr. Kevin T. Smith, Torrey Young, Frink Rinn and Chris Rippey are long-active practitioners in arboriculture. Dr. Kevin Smith is a research scientist and has published over 150 research and educational articles. Torrey Young started his career in Arboriculture in the early seventies as a tree worker and has evolved into a leading Arboricultural Consultant in California. Frank Rinn has a Master’s Degree in Physics and is a technology innovator whose inventions have helped to move our industry into the age of data-driven tree care. Chris Rippey started his career chipping brush for his dad. He is an active tree worker and managed a preventative tree maintenance program for the Seattle Parks System.
These tree industry veterans will combine their diverse experiences to present a comprehensive perspective on preserving veteran trees. Each presenter will give a talk relating to their unique arena in the care of veteran 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 ranging from residential sites to remnant forest trees in your neighborhood park. A variety of tree risk mitigation options will be explored.
Workshop participants will walk away with a better understanding of the options for preserving veteran trees. They will get access to the experience of four people who have made trees their life’s work. Attendees will better understand why to prune a veteran tree, the physiology of older trees, why goal specific pruning is key, why less is more, and why we must be brave and innovative in order to make the often hard choices to preserve and manage veteran trees.
This workshop will conclude with a substantial panel discussion with our speakers.

- 8:45-9:45am Case Studies of Veteran Tree Care (Chris Rippey)

- 10:45-11:00am Break
- 11:00-12:00pm Biology of Veteran Trees (Dr. Kevin T. Smith)

- 12:00-12:30pm Lunch Break
- 12:30-1:30pm How Technology and Math Helps in Preserving Veteran Trees (Frank Rinn)
- Technologies and methods for assessing structure and function of veteran trees and preserving these natural habitats as long as possible with sufficient safety
- 1:30-1:45pm Break
- 1:45-3:30pm Panel Discussion with the Speakers moderated by Jon Pywell, Urban Forester of the City of Corvallis (All Speakers)
- 3:30-5:00 OPTIONAL Field Session (weather dependent)
- Participants and instructors will drive to nearby Seward Park to discuss topics covered the day’s presentations.
Topics for the panel discussion will include:
- What are your opinions on managing public perception and fear following a major tree failure event which resulted in death or manor property damage?
- How does the panel determine likelihood of failure for trees that already appear impossible still to be standing?
- What are your thoughts on the 30% rule?
- Lapsed pollards and topped trees.
- How do you manage lapsed pollards/old topped trees which have developed old sucker growth above compromised stems?
- (using a large drawing) how would you prune this trees?
- Can we talk about root decay?
- Propping designs, what do you use and when do you use them?
- Can you all comment on how we can grow the veteran trees of the next generation? It seems that we are running out of locations that will grow trees to old age, especially in highly urban areas. Isn’t some part of veteran tree care the preservation of “veteran soil”?
Dr. Kevin T. Smith is Supervisory Plant Physiologist for the US Forest Service and Affiliate Professor of Biology at the University of New Hampshire, Durham. A plant pathologist and mycologist, Smith investigates the growth and defense processes of compartmentalization in living trees and the long-term relationships of trees and forests with decay fungi. Smith has published more than 125 research and educational articles and has received awards for research and science delivery from the US Forest Service and the International Society of Arboriculture.
